    Alienware Monitors are Simply Awesome

    Yes they are slighting overpriced. But you get what you pay for. Color is awesome, latency is top notch and the clarity is bar none excellent. Very little black light bleed and always top notch displays come from Alienware. At least in my experience. No tearing because of Nividia Gsync. I love the panel and the OSD controls. You can also charge phones and tablets from the small hub on it, even without it being connected to the pc. Its a great monitor. Is it worth it for the price? Only if you really want it to match with other Alienware accessories, or you can get it on sale. No question about the quality though.

    Awesome for 360 fps. I play fortnite. I can tell you that much that is good for that game. Now if we can get 4K resolution at 360 fps for a decent price then we be in there. Lol. Probably gonna be a 10k monitor if one is made.

    Great performing monitor but best geared for FPS enthusiasts. Image quality is good to very good for me stops short of excellent. HDR is just average. If you’re looking for the fastest monitor for esports or FPS shooters, this is the monitor for you. I have mine paired with an Alienware M15R2 with a 2080 max Q. My laptop can not muscle this thing past 200fps with settings turned down. But I don’t run it that way. For those wondering about how it might impact your laptop performance - I’d say I gained about 5-6% due to the fact that using the display port on laptop bypasses the Intel GPU and runs soley on the 2080. For that reason alone an external monitor is worth the add to your gaming laptop.

    IPS really did surpass TN. Cheat the Value w/TAM!

    Calibration Setting (From RTINGS.com) - Works best IMO Picture Mode: Custom Brightness: 29 Contrast: 75 RGB: 100-96-93 PROS: +PRICE: Total Access Member Here: Like you, I thought Total Access gets first dibbs. Now, I'm like I might as well keep it. Up to 2 years of free insurance (with deductible)? Why not buy open box excellent everything? Currently this is $200 off + $50 off with Open Box Excellent. Total Access Protection Check. +Upgraded from the AW2518H (TN 240 Hertz). WHAT A DIFFERENCE between IPS and TN. Like many out there, I was extremely skeptical of performance. However, the input lag on this IPS panel ACTUALLY BEATS the TN. Seriously, like HUH? +IPS VS TN: IPS will always win but the problem was it didn't meet TN performance levels before. However, tech changed and IPS has beaten TN. I still am in shock about that but it is 100% true. +360 Hertz is amazing if you can reach it. I play CS:GO more than any game out there logging over 2000 hours. 360 hertz is worth it to me. Is it worth it to you? Honestly, you can only get 360 hertz on some games (not new ones). If you are buying this for other higher requirement games, there's no point to get 360 hertz because you'll never reach it. Maybe with Alder Lake + 3090...we will see but doubtful. +New tech is better. This one actually looks better than my AW3420DW despite them being the same ish tech. RTINGs gave this monitor super high marks in all but contrast (IPS, blacks don't look black). I'm hoping one day OLED will hit this spec or better as OLED is the future once they figure out how to do 360 hertz with it and low ms. CONS -Ghosting: Extreme Mode has ghosting for sure. Super Fast and Fast are great but it isn't 1ms. I stuck with Super Fast. -360 hertz is a niche game market. It only works with older games if properly matched with good CPU + GPU. Otherwise, honestly you don't need it.

    It is a solid product that delivers perfomance, color, build quality and talk about quality control. I grew tired after countless purchases of other brands, there was always something, dead pixel, build felt flimsy/delicate, washed colors etc... I see myself sticking with Alienware from now on.

    360hz IPS Native G-Sync Only 379$???

    360hz ips monitor with native g-sync for 380$? It would have been crazy to pass up a deal like that. -Phenomenal Input Lag of only 1.7ms! -Best Response time with 0% overshoot out of the 360hz monitors Came from Benq xl2540 and the better colors and ips made it a lot easier to spot people in Apex Legends. Would recommend putting digital vibrance up 10% so the colors pop more for gaming.

    This is for PC gaming, but I can also confirm that even w/o Freesync, on the XSX, it can run VRR @120hz + HDR all at the same time, which is very rare. Build quality is top notch and it is the fastest monitor out there w/ the lowest input lag according to Rtings. When set to PC RGB, the blacks levels are amazing for an IPS panel. Price matched at almost 50% off, I am very happy with this purchase.

    What a monitor! The color is great and can be adjusted to your liking. The input lag is insanely low. It's a noticeable difference moving up from 240 hz and now 240 feels sluggish to me. If you catch it on sale like I did, it's an insane value for how good it is.

    fantastic vivid colors; fast refresh rate; expensive; took up too much room on the desk; highly suggest using a side arm mount rather than placing directly on your desk

    I absolutely LOVE this monitor!!! Paired my monitor with a Ryzen 7 3700X, NVIDIA RTX3080. I haven't been playing long on it but I can see a huge difference vs my 144Hz monitor. The only part that bothers me is the large base that takes lots of desk space. Definitely look at getting a vesa mount.

    I'm using a 3070 system with a i910850k and I think it's a great match for some games but I literally mostly only play CSGO in CSGO at 1080p all maxed out I get around 320-400 fps all the time.. Sometimes though depending on the setting I'll get some choppy movements outta nowhere... strange flickering almost I've used it with G-sync, ULMB, and without any of them at 360hz and I've gotta say it runs the smoothest at ULMB 240-300Hz at 360hz I get random glitches not a lot but they annoy me at times... I'm still giving it some time on deciding to return or keep because it is a pretty awesome monitor nonetheless Very great gaming monitor, I do believe they should have some updates on this new monitor because it needs some work.

    I bought two of these when on sale. These monitors are well worth the money and even more so when found on sale. These run 4K quality videos or games great. I use them for my PC and PS5 and the image quality is awesome and smooth. Really like the G-Sync as this is my first time having such a PC with higher end monitors and it is neat with optimization for games.
