Customer Ratings & Reviews

Great product right out of the box. Clean and smooth look with very easy set up and ultimately great visuals and speed to back it up. Great for new and old PC gamers.

Looks great and runs great picture quality is exactly what I wanted

It’s 2026 and we have more monitor (and PC solutions) than ever before, while prices have continued to fall (well, all but HDDs and RAM which have reversed during this AI data center explosion). Fortunately most of those servers are headless and not requiring dedicated monitors, which is a benefit to we consumers. Today we’re looking at the Samsung Odyssey G4 27-inch speed demon of a monitor, featuring a 300 Hz scanning rate, with 1 millisecond response, but less resolution than discriminating users may demand. If you play FPS and quick response games you’ll likely love this monster of a monitor. Albeit caveat emptor, this 300 Hz speed comes at a cost of resolution, featuring just 1920x1080p max resolution. If i had my druthers I’d likely have selected a 1440p 240 Hz screen, though my usage is not just gaming, but also general purpose, work, security, etc. When gaming speed matters, it is very noticeable of the refresh rate over 60 Hz (duh?), 120 Hz, 144 Hz, and 165 Hz monitors, supposedly even newer 240 Hz monitors though i could not tell a difference from my primary monitor over DisplayPort 1.2, rightfully so as the HDMI 2.0 input has max refresh of 240Hz. Don’t get me wrong, i remain mostly impressed by this monitor, however i personally feel a 1440p w 240 Hz refresh or ultrawide monitor rate might appease more than just hardcore FPS speed prioritized customers. PROS +simple assembly +HDR 10 support +300Hz refresh rate (DP 1.2) +240Hz refresh rate (HDMI 2.0) +super fast 1ms response rate +anti-glare display screen +included DisplayPort cable +Nvidia G-Sync / AMD FreeSync +IPS panel = excellent wide-screen viewing +both HDMI and DisplayPort inputs (no USB-C though) +makes a great 2nd screen CONS -lack of 4k -no HDMI 2.1 -limited pixel density -slight backlight bleed -only 1920x1080 resolution -needs HDMI dongle on a Mac -no on- board speakers, audio out -on single display not the primary imho -less Cinematic than a deeper black VA panel CONCLUSION While there are several valid use-cases for a low-cost, ultra fast monitor sure to appease speed freaks, I feel the lack of resolution is a major drawback, and recommend a pre versatile product. RECOMMEND - look for Samsung 1440p or 1600p ultrawide res with 240 Hz refresh rate imho if you want to extent the longevity and prevent a 3-5 year paper weight taking up space.

Monitor quality keeps improving, unfortunately my wife's eyesight is going the other way.  Besides size, I'd not considered them helping people with eyesight problems.  I recently saw that the new Samsung monitors had a new and improved Matte finish. I've had matte finishes on other notebook's/monitors, but they had a negative effect on the quality of viewing.  My wife's vision problem is exacerbated by screen reflections.  My hope was a screen with an improved matte finish will be easier for her to view, and a 27" will be a big step up from her notebook.  Unpacking and setup of the monitor was very extremely easy.  One built in screw attached the monitor arm to the monitor base.  The Monitor arm is built so that the monitor can be viewed in either portrait or landscape orientation (yea) with a reasonable amount of tilt.  The G4 monitor has a HDMI and a Displayport connector, as well as power in and audio out (headphones or for powered speakers). It has a 100mm VESA mount on the back.  To test it I hooked up to one of my notebooks.  Once plugged in I connected the HDMI Cable to the notebook and monitor, it promptly displayed the notebook's screen on the G4 monitor.  By default the G4 was a little dim and colors were not quite right.  I used the on/off - Joystick on the lower left of the back side of the monitor to go into the set up menu. I increased the brightness, contrast and sharpness to pretty much match the display of my notebook.  The monitor on stand is 16" tall, and is 24" wide. With a stand it's 9.5" deep and weighs 9.9 lbs.  The stand does allow height adjustment and allows you to use the monitor in portrait mode.  It has a very small bezel so two could be used together without much distraction.  It supports full HD (‎1920x1080) with AMD FreeSync, and claims to have 1ms response time with up to a 300 hz refresh rate.  It includes both a HDMI cable and a DisplayPort cable. Once I made the color adjustments I found the color was very pleasing.  And the matte finish is remarkable.  NO reflections, you get close to the screen and look in any direction you get true colors without any reflections, it's very immersive when you lean in.  To me it is a great example of how much monitors have improved and continue to improve.   This is strictly a 1920x1080 HD monitor, not a 2K or 4K display.  It does support HDR10 (extended blackness, mostly having to do with video), yet its blacks are quite deep and its colors quite consistent. And running with either the 100hz or 300hz refresh rate there is absolutely no flicker. It supports 3 levels of Eye Saver (low, high and off) mode which reduces potentially harmful blue light emissions. I thoroughly enjoyed watching videos on this display.  It has multiple gaming modes which adjust up the brightness and it sharpens the contrast settings automatically. It also has a Response Time Settings and auto sync to prevent tearing when gamings fast moving images (seemed pretty effective in Asphalt Jungle and Turismo 7). In normal PC mode the game mode setting improves screen readability from a distance, the text is sharper/cleaner.  But for movie viewing it hurt dark images significantly.  I don't recommend game mode for video viewing or video editing, all dark areas are blown out.    This is not the highest performing monitor you can purchase (but you know that), but for its price you get a very high quality product.  It makes a great extension monitor. And my wife absolutely loves it.  The lack of reflections is great for her vision issues.  The audio quality was MUCH better than I expected (but no built in speakers).  The quality is very good. The colors are nearly perfect, when I compared my notebook (w/OLED Display) to this monitor. The monitor does great with gaming but still only Full HD; and does not have the sharpness of an OLED screen, but it may be the best IPS screen I've ever seen. It also seems like a great monitor for Image Editing or graphics work (except for the lack of 2K/4K resolution). But I do like this monitor a lot, for day to day computer use it's excellent. I think it will be perfect for my wife.

In a time when it can cost more than a grand (or two) for a video card that pushes 4K or more WELL, it was actually a treat to spin up a few AAA titles at 1080p on the Odyssey G4 and top out at 300 fps. It was a little difficult to drop down from my 1600p ultrawide at first, but the truth of the matter is that the G4 actually had a nice enough picture, especially with games having good HDR implementation, that I could see sticking with the 27” G4 if I didn’t have a larger screen already dedicated to gaming. The spec sheet on this monitor looks impressive on the specs that matter: 300Hz refresh, FreeSync Premium, 1ms response time, and HDR10. The screen has a matte finish, so you don’t get a lot of distracting reflections from bright room lights, and the IPS panel means off-angle viewing is still very clear. There’s a black-level “equalizer” that bumps up shadow detail (to spot those monster-spawn points in dark corners) without completely overblowing the picture. Several differently shaped aimpoint overlays are available to improve center-shot accuracy. Like most monitors, you get a handful of gimmicky color modes supposedly optimized for different types of games (RTS, FPS, Sports, etc.) as well as low and high “eye saver” settings (typical blue-light reduction with ultra-warm orange-ish whites), another setting for graphic design (which I suppose is optimized for RGB accuracy), and one for “entertainment.” There is also a custom setting that allows you to dial in a number of standard picture controls (brightness, contrast, tint, saturation, sharpness) as well as some slightly more advanced adjustments like gamma, white balance, shadow detail (which is, frustratingly, a different adjustment than the black equalizer). Basic performance specs indicate a 1000:1 contrast ratio and typical 300 cd/m2 operating brightness. The numbers are…fine…on their own, and will serve you well in a bright room, but they aren’t anything impressive enough to really make your jaw drop. Assembly takes all of 30 seconds: toolless attachment of the single support column via single thumbscrew to the (thankfully) smallish base, then snap the screen onto the mounting points and you’re done. There are standard VESA mount points as well for those of you using a display arm or other mount. A small plastic band near the bottom of the stand provides for a sliver of cable management, and the stand allows enough vertical movement to put the screen in portrait mode in either left or right orientation. There is a USB port at the back, but it’s only for servicing the panel, not for multimedia display or moving data around on a thumb drive. What you DON’T get is a lot of anything else--the tradeoff you pay for getting some of those enviable monitor stats at such a reasonable price. There are only two inputs, DP (1.2) and HDMI (2.0); DP supports 300Hz output while HDMI will push 240Hz max. There aren’t any speakers, though there is a headphone jack in the back. There is a six-stage gamma adjustment, but no indication as to the value of each setting. Similarly, there are color temperature settings, but nothing to indicate how close or far each one is to the 6500K neutral. The panel does support HDR10 display though it does not appear to be HDR certified, and I did not see any evidence that the panel supports 10-bit color. There is also a response time adjustment in the monitor’s menu; but, like the gamma and color temperature settings, there is no direct indication what the response time adjustments (standard, faster, and extreme) correspond to in terms of literal panel timing. I’m guessing the highly touted 1ms response time is activated only under the extreme mode. FWIW, I didn’t see any visible glitching running the panel at the extreme setting, but the tradeoff is that you have to turn off adaptive sync to make any timing adjustments, and then there isn’t any indication of just what the response time is left running at (3ms? 5ms?). Despite sounding a little harsh, the G4 actually produced a stellar image, especially in games that have native support for the expanded HDR colorspace. I was more than pleased with the deep, glowing neon hues and over-saturated colors in Horizon Forbidden West (non-HDR) and the incredibly realistic, gritty feeling of the dingy cityscape in Dying Light – The Beast (native HDR). The G4 does not carry G-Sync certification, but my RTX 4090 rig recognized the panel’s G-Sync compatibility immediately and the action was sublimely smooth. Backlight bleed was minimal, confined to just a bit of bright bloom primarily in the upper right corner, but during normal use it wasn’t intrusive enough to be noticeable. Still, it’s a fast IPS panel at a reasonable price point so you aren’t going to see OLED-level inky blacks. The only real COMPLAINT I have about the G4 is actually a design issue that frankly drove me nuts. The 4-way joystick/menu button is hidden at the back of the monitor…not on the side, not at the bottom, not at a convenient edge, but far enough in the back that it was a struggle to find it every single time. I suppose once you get the settings dialed in to your liking you might not need to access the controls very often, but fiddling blind with a rear-mounted control is already irritating enough…putting the control it in a place that isn’t easy or intuitive to locate was frustrating for no good reason. Similarly, the headphone jack is also WAY in the back which may make for even more frustration if you are someone who routinely switches between headphones and external speakers. So where does that leave the G4 in the VERY crowded PC gaming monitor market? It does its job well and hits the high points of fast response time, adaptive sync up to 300Hz, HDR support, but it does fall a little short in terms of some usability issues, and some run-of-the-mill specs for brightness and contrast. Still, the monitor carries a reasonable price tag, especially on sale, and for the money, will provide a very pleasing picture with a few high-horsepower gaming capabilities thrown in for good measure.

I recently acquired the Samsung 27" S27HG40DEN to replace an older screen that was starting to look pretty washed out. Overall I'm happy with it for the price, but it's not perfect. First off, the good stuff: Gaming feels really responsive on this thing. I play a mix of shooters and some open, world games, and the motion is smooth enough that I don't notice any annoying blur or lag during fast action. It's definitely better than my old 60Hz monitor , everything just feels snappier. I also really like that it has a portrait mode option. I rotate it sometimes when I'm reading long articles or working on documents with a lot of scrolling, and it's super convenient. The stand makes it easy to pivot, which is a nice touch I didn't expect at this level. Picture quality is decent for normal use , colors look okay and it's bright enough for my room. No major complaints on the build either, it feels sturdy and the thin bezels make it look pretty modern on my desk. The one thing that bugs me though is the resolution. It's 1080p (Full HD), and at 27 inches I can kinda tell. Text isn't as razor sharp as I'd like, and when I watch videos or play newer games I find myself wishing it was 4K. I know 4K would probably cost more, but man, once you've seen that extra clarity it's hard to go back. If you're mostly doing casual browsing and lighter gaming it won't bother you much, but if you're picky about sharpness like I am, you might feel the same. Bottom line: It's a good, no, frills 27" monitor that does the job well for gaming and everyday stuff, especially if you value that portrait rotation. Responsive performance is there, and I like the flexibility. Just know that if 4K sharpness is important to you, this one falls a little short in that department. Would I buy it again? Probably yes for the money, but next time I'm saving up for a 4K version.

Best bang for your buck. 300ms refresh rate is so amazing for first person shooters . The monitor is so crispy ans enhances your game 10 fold. Worth every penny. If you play arc, call of duty or battlefield you need this

My 34" ultrawide 4k monitor was too big for Esport shooters so I needed something "cheap" and this 300HZ monitor was the perfect choice.

This monitor is exactly what I needed for my gaming needs. Crisp picture and great refresh rate.

The Samsung Odyssey G4 27" Gaming Monitor exceeded all of my expectations. As part of my first gaming PC build, I wanted a monitor that could handle fast-paced games while still delivering a great-looking picture, and this monitor does exactly that. The 300Hz refresh rate is incredibly smooth, making games feel responsive and fluid. Whether I'm playing Fortnite, Cyberpunk 2077, GTA, or other action-packed games, everything looks sharp and runs beautifully. The 1ms response time helps eliminate motion blur, and AMD FreeSync Premium keeps gameplay smooth without screen tearing. The Fast IPS panel provides excellent color quality and wide viewing angles, while HDR10 adds extra depth and detail to supported games and content. The 27-inch size is perfect for gaming, offering plenty of screen space without overwhelming my desk. Setup was quick and easy using DisplayPort, and the monitor worked flawlessly right out of the box. The sleek black design also gives my gaming setup a clean, modern look. If you're looking for a high-performance gaming monitor with exceptional speed, image quality, and value, the Samsung Odyssey G4 is an outstanding choice

This Samsung gaming monitor is amazing. I noticed a huge difference compared to the other brand that I had glad I purchased this. Thank you so much Best Buy.

The visual side of the monitor looks fantastic, the adjustment towards the height and angle make it an amazing monitor for either gaming or work

Having connection issues when using HDMI cable. Picture is incredible.

Good quality the monitor has fast response time and will do the job

From the frist day i got it i tried my best to max it out but just couldn't i have a pretty beefed up pc a d it just worked liek a charm with 244hz the gameplay or anything is just smooth. Only dislike is the price but after buying i understand why it was priced the way it was. I would definitely recommend

This is an amazing monitor, priced great and performs extremely good

exception gaming monitor with great hd and perfect size for a desk

The lighting areas and very bad in the corners of the screen and black scenes do not look black at all. Besides that I have no complaints at all. The gameplay is very smooth and the screen size is great for the money.

The monitor works great with a clear image. The display port cable included was very stiff and lost connection everytime I moved the computer but I already had a better cable to switch to because I didn't know the monitor came with cables.

TL;DR - the Samsung Odyssey G4 (G40H) is a solid 27 inch 1080p monitor for those who value frame rate over resolution. It pairs well with cards in the same performance class as the AMD Radeon 7600XT, Intel ARC B580, and Nvidia GeForce RTX 5060Ti. Color performance is spot on, AMD FreeSync and VESA VRR work as expected for variable framerates, and HDR10 does add depth to video, graphics design, modeling, and gaming content. However, there are some limits as to what the HDMI and DisplayPort ports can do. I can only recommend this display for eSports gamers looking for a relatively inexpensive 300Hz panel. Unboxing and setup: Packaging is minimal, but in a good way. Everything you need to get started is in the box, too - HDMI and DisplayPort cables, power adapter and cord, and desktop stand. Assembly requires no tools - attach the stand to its base using a thumbscrew, snap the monitor in place on the stand, and remove the protective film from the display. Then you'll attach power and video cables, hook it up to your computer or gaming console, and you're good to go. For PC users, I HIGHLY recommend using the DisplayPort connection over the HDMI connection as you'll be able to get a higher refresh rate with HDR and 10-bit color enabled. If you plan on switching back and forth between a PC and a game console or two separate PCs, there is a headphones/audio out port on the back of the monitor you can attach analog speakers or an analog soundbar to. My biggest gripe here is that Samsung insists on using an external power brick with their displays, something I've never been a fan of no matter what brand it is. I know they wanted to go for a thin form-factor with this display, but I'd rather deal with just a power cable instead of a "line lump" when it comes to cable management. Usage: When you set up the monitor initially, it'll display a QR code for registration. You can get past this screen using the joystick interface. You'll also find the initial setting for the monitor to be "Eco Mode", which is a welcome change from nearly every monitor and TV I've used in the past being set to "Vivid Mode" from the factory. While Eco doesn't provide the best color balance, it also doesn't fry your retinas. For Windows PCs, you'll want to head to your display software first (Intel Graphics Software, AMD Adrenalin, Nvidia App) and make sure to enable VRR/FreeSync and turn up your bits per pixel setting. Then in the Settings App, you'll need to go to Display and advanced Display to turn on "Dynamic Refresh Rate) and crank your refresh rate up to the highest setting it'll allow. Note that the power draw for anything above 60Hz is negligible compared to 60Hz, so feel free to set it as high as you're allowed to. On most modern Macintosh computers, you'll be able to change the refresh rate and bits per pixel setting entirely from the Displays portion of the System Settings app, and enable variable refresh rate as well. For Linux users, your Display control panel should work similarly to macOS's Displays settings pane, meaning you won't need to go into the driver app to enable VRR or change bits per pixel. So how well does it work? Very. I played games using a Nintendo Switch 2, a ARC B580/Ryzen 7 7800X3D PC, a Radeon 6950XT/Ryzen 7 7800X3D PC, and a GeForce 5070 Mobile 8GB/Ryzen AI 350 laptop. In games that consistently ran above 120FPS, action was very smooth. For more demanding titles like Cyberpunk 2077, Doom Dark Ages, and Black Myth: Wukong, the variable refresh rate made it so screen tearing wasn't a thing. For audio editing and production in macOS, I found a 120Hz refresh was adequate for scrolling multitrack projects in Logic Pro. Watching Amazon HDR content showed strength and weakness in panel brightness - while muzzle flashes in the movie Fury were bright and punchy, the dark backgrounds were crushed by the limits of LCD technology without a full-array local dimming backlight. The stand is also super nice on this monitor. Vertical adjustment, full screen rotation, and the ability to turn the panel left and right are some really nice touches here, and moving the screen didn't feel like I was moving the base as well. This display also doubles as a decent 1080p TV for a college dorm, bedroom, or studio apartment. Pair it with a streaming media player and a pair of speakers or an analog sound bar, and you have a perfect streaming companion. Drawbacks: On a technical standpoint, I would have liked to see HDMI 2.1 and DisplayPort 1.4 or later. While HDMI 2.0 and DisplayPort 1.2 provide enough bandwidth for a 1080P high refresh rate experience, the newer versions of these ports would have allowed 300Hz and 10-bit full RGB display. On an aesthetic standpoint, I would much prefer an integrated power supply in the monitor instead of a line lump When it comes to cable management, it's one more thing to deal with. Yes, the monitor would be about a half-inch thicker, but that's a tradeoff I can stand. In closing: Again, the Samsung Odyssey G4 is a compelling option for those wanting to make the jump into high refresh rate gaming. 300Hz 1080p is perfect for eSports. The monitor also doubles as a good all-arounder in day-to-day performance. I did have to ding it for a couple of things I see as shortcomings, but it's not enough where I wouldn't be able to recommend it. It is a good option for eSports gamers though, and that's who I recommend it to.
