    LG UltraGear 27" OLED 480Hz —

    So I’ve been running games on the LG UltraGear 27" OLED QHD 480Hz and honestly? It’s cracked. Display Quality • The OLED panel is gorgeous — true blacks, insane contrast, and colors that pop off the screen. • QHD resolution hits the sweet spot: sharp enough for immersion, but still manageable for high FPS. Performance • 480Hz refresh rate is next-level. In Valorant and CS2, it feels like my aim is glued to targets. • 0.03ms response time means no ghosting, no blur — just pure, instant feedback. • Adaptive sync with NVIDIA G-SYNC and AMD FreeSync Premium Pro keeps frames smooth even when things get chaotic. Features & Build • Gamer tools like Black Stabilizer and FPS counter give you an edge. • Sleek design with adjustable stand and subtle RGB accents. • Ports are stacked: HDMI 2.1, DisplayPort 2.1, USB — future-proof for next-gen setups. Pros • OLED visuals are jaw-dropping • 480Hz + 0.03ms = competitive edge unlocked • Smooth adaptive sync support • Solid build and ergonomic stand Cons • Pricey (around $999) • Needs a beastly GPU to push 480Hz • SDR brightness isn’t as high as LCD rivals • No built-in speakers Final Verdict: This monitor is basically a hardware buff for competitive gamers. If you’re sweaty in ranked, it feels like you just unlocked a cheat code. For casuals, it might be overkill, but for esports-level grind? Absolute god-tier.

    LG UltraGear 27GX790A-B: 480Hz OLED Gaming Experie

    I picked up this LG UltraGear at the end of last year, and after about three months of use, the overall experience has been nothing short of "stunning"—especially for someone like me who mainly plays FPS and racing games. The improvement is immediately noticeable. Display Quality: This 27-inch OLED panel is truly top-tier. The QHD resolution, combined with OLED's self-lit pixels, delivers perfect black levels and incredible contrast. Dark details are crystal clear, and colors are far more vibrant and accurate than my previous IPS screen. Whether I'm playing CS2 or Forza Horizon 5, the visuals are deeply immersive. Gaming Performance: The 480Hz refresh rate paired with a 0.03ms response time places this monitor at the very top of the current esports lineup. In fast-paced games, motion is unbelievably smooth, with almost no noticeable blur or ghosting. Tracking targets and predicting movement feel much more precise. Both NVIDIA G-SYNC and AMD FreeSync work flawlessly, eliminating screen tearing and stuttering even at high frame rates. Design & Build: The stand is solid and sturdy, offering easy adjustments for height, tilt, and swivel. The base's RGB lighting is tasteful and syncs seamlessly with my Razer peripherals, creating a great gaming atmosphere. The connectivity is also sufficient: two HDMI ports, one DisplayPort, and USB ports make it easy to connect my console and other devices. Minor Drawbacks: The price is definitely on the premium side, and as with any OLED display, I'm mindful of potential burn-in, so I avoid leaving static images on the screen for extended periods. Additionally, the base takes up a bit more desk space than I expected, which is something to consider if you have a smaller setup. Final Verdict: If you're a hardcore gamer chasing the ultimate in smoothness and visual fidelity, and your budget allows, this monitor is worth every penny. It's a game-changer for competitive play and delivers a premium experience that justifies the investment.

    Generational leap-like taking off the blindfold

    I upgraded to this LG UltraGear (27GX790A-B) from a standard 1080p 60Hz monitor that I used for years, and the difference isn't just an improvement—it's a completely different reality. The "Wow" Factor: The most immediate impact is the OLED panel. The description "infinite contrast" sounded like marketing fluff until I saw it. Black levels are actually black, not gray, which makes every other color pop in a way I didn't think was possible. It honestly feels like I was color blind before and am finally seeing true colors for the first time. The jump to 1440p at 27 inches also strikes the perfect balance of sharpness without being impossible to drive. Performance: Going from 60Hz to 480Hz is mind-bending. The smoothness is hard to describe; mouse movements and fast-paced gameplay are liquid-smooth with zero blur. Combined with the 0.03ms response time, everything feels instant. Even if you aren't hitting 480fps in every game, the motion clarity of this OLED panel combined with Nvidia G-Sync destroys any LCD screen I've seen or used.

    Great Monitor for the Price

    I picked up this monitor on sale, and for the price, it’s an absolute powerhouse. The 480 Hz refresh rate paired with a 0.03 ms response time delivers motion clarity that’s on another level—fast-paced games look razor sharp even in hectic moments. The OLED panel produces deep blacks, vibrant colors, and stunning contrast, so the visuals in every game feel incredibly immersive. Performance-wise, it’s a dream for competitive gaming, and even cinematic titles benefit from the HDR and color accuracy. The build quality feels premium, and G-SYNC/FreeSync compatibility ensures smooth gameplay across different GPUs. It’s not perfect—brightness isn’t the highest compared to some newer OLEDs, and there are no built-in speakers. Also, to take full advantage of 480 Hz, you’ll need a pretty powerful PC. But if you can grab it at a discount, it’s one of the best high-refresh OLED monitors for the money. I was playing the Battlefield 6 beta with this monitor and it looks great and with the high FPS it was a truly different experience compared to typical IPS monitors. Other games look great Witcher 3 looks great as well. So many games look great. Highly recommend picking up this monitor; however, if you can wait for it to be on sale that would be even better.

Questions & Answers
  • Is this monitor true 2.1 Display Port? Im hearing it cant do 80Gbps

    The DisplayPort 2.1 ports on the LG 27-inch UltraGear OLED QHD 1440P 480Hz 0.03ms G-Sync® Compatible DisplayPort 2.1 Gaming Monitor, Model # 27GX790A-B are "true" DisplayPort 2.1 ports. DisplayPort 2.1 supports three UHBR rates: UHBR10 (40Gbps): Suitable for mainstream 4K/120Hz gaming and general multitasking. UHBR13.5 (54Gbps): Supports 8K/60Hz with Display Stream Compression (DSC), ideal for premium home theaters or productivity. UHBR20 (80Gbps): Enables uncompressed 8K/120Hz or dual 4K/144Hz setups, suitable for high-end gaming and professional workflows. The LG 27GX790A-B monitor features a DisplayPort 2.1 bandwidth of UHBR13.5, which is limited to 54 Gbps. This bandwidth allows for high-resolution and high-refresh-rate gaming without the need for Display Stream Compression (DSC), but does not mean it's not a "true" DisplayPort 2.1 port. It just supports a different UHBR rate...^Ivan.

  • DP2.1 standard on UHBR13.5 or UHBR20? also, does monitor feature BFI? so far way too many conflicting information provided from various LG sources making me question whether preordering was the right choice

  • May i recieve this product for free? i would like to review it on my tiktok page for my almost 2,000 followers, thanks!

    Regrettably, we do not have the contact information for who you would need to contact from LG's PR team to request an LG UltraGear™ 27" OLED QHD 480Hz 0.03ms NVIDIA G-SYNC, AMD Freesync™ Premium Pro Gaming Monitor (HDMI x2, DisplayPort, USB) - Black, Model # 27GX790A-B, to review and get to keep after reviewing it. You would first have to build a portfolio of reviews to pitch directly to our PR team & if you already run a blog, a YouTube channel, or write for an online publication, you can reach out directly to our public relations (PR) team to request a review unit, but normally, you should not ask for an expensive monitor. Start by requesting smaller, less expensive items to build a portfolio. You can find Find the press or PR email on our website. Emphasize why reviewing our specific monitor model fills an information gap for consumers...^Ivan.
