To be fair, the font rendering on the LG UltraGear 27GX790A isn't too bad. But this isn't a high-DPI display and, for the money, you can have something far more practical for getting work stuff when you're not playing games. Again, $700 or £800 is a load of money when you can get a decent 27-inch 1440p IPS monitor for a third of that cost , maybe even less.

While there are a few strong contenders that could earn the place of being the best gaming monitor for Counter-Strike overall, the LG UltraGear OLED 27GX790A-B stands a touch higher than the competition, thanks to a balance of speed, responsiveness, and relative value for money. The main highlight is this monitor's impressive 480Hz refresh rate , which is coupled with an equally impressive 0.03ms response time . As someone who has dabbled with some seriously high refresh rates in the past, it really does become a challenge to adjust once you drop back down. Not only that, but this combination essentially ensures you're going to be one step ahead of almost any other player you come across, and that should stand you in good stead to pick up more kills and, ultimately, win more games.

LG’s UltraGear GX7 represents gaming monitor technology at its current peak. It’s frighteningly fast, gorgeous to look at, and packed with features that deliver tangible benefits rather than marketing tick-boxes. The premium pricing will put it out of the fiscal reach of casual gamers, but for enthusiasts building no-compromise setups or professionals needing a display that handles both work and play exceptionally, the GX7 is one of the finest options available. It must be good, because I was genuinely sad when sending it back after reviewing it.

1440p 480Hz OLED for $999 Article

Any game that is capable of reaching that glorious 480Hz refresh rate cap is going to look and feel absolutely incredible on the GX7. The 480Hz, paired with the 0.03ms (GtG) response time, made titles such as League of Legends, Apex Legends, Overwatch 2, Valorant, Counter-Strike, DOOM: The Dark Ages, and Battlefield 6 feel absolutely incredible. Motion clarity performance in all of the aforementioned titles was stellar. I was able to clearly see fast-moving targets with minimal blur, making hitting shots very easy.

The LG 27GX790A stands out as a high-performance gaming monitor that delivers on its promise of exceptional visual quality and smooth gameplay. What we found particularly impressive is its class-leading 480Hz motion clarity and over 96% DCI-P3 color coverage, which earned it high praise from nearly every expert source. With G-Sync and FreeSync Premium Pro certification, it's clear this monitor is built for the most demanding esports players and enthusiasts. Its sleek, virtually borderless design is also a standout feature, enhancing the immersive experience. However, the lack of internal speakers and subpar text clarity for productivity tasks are notable downsides, as is the premium price point and the grainy 'dirty screen effect' some owners report from the matte coating.

Being an OLED gaming monitor, there were no complaints whatsoever regarding the UltraGear 27GX790A-B's input lag or response times. VRR is also well-supported, as is G-SYNC compatibility. That said, there is some noticeable VRR flicker, which is common with OLEDs. This is easily fixable, however, simply by setting a frame cap, or by turning off VRR when gaming.

Frequently asked questions

It ranks #24 of 30 on our gaming monitors tier list, in D tier. That placement draws on 16 cited sources across 15 outlets.

None of the 16 sources with a clear view is critical of it. OLED burn-in remains a long-term concern. Automatic brightness limiting can affect use. Model-specific warranty and firmware support are less clear. Ranks behind several more compelling OLED choices. OLED burn-in risk.

Nobody we can recommend over the alternatives, even though it is a strong current high-refresh OLED. It is a 480Hz 1440p panel with DisplayPort 2.1 and excellent contrast, and it ranks highly in a current OLED comparison, but it sits in D tier on our gaming monitors board because the evidence gives less confidence about long-term support and firmware longevity. Buy the Alienware AW2726DM in S tier for safer ownership, or the Asus ROG Swift OLED PG27AQDP in C tier if 480Hz competitive play is the goal.

The Alienware AW2726DM is the top pick and the safer years-long purchase. If you want an LG OLED specifically, the LG 27GX700A-B in B tier is the board's better-ranked LG, a 280Hz 1440p OLED with a near-instantaneous response time. If 480Hz is the requirement, the Asus ROG Swift OLED PG27AQDP has a broader testing record and sits a tier higher.

Support uncertainty, not performance. The verdict says the available evidence gives less confidence about long-term support and firmware longevity, and the cons add that model-specific warranty and firmware support are less clear and that it ranks behind several more compelling OLED choices. On the screen itself the pros are strong: high-refresh OLED performance, excellent contrast and image quality.

OLED burn-in is listed twice in the cons as a long-term concern, and automatic brightness limiting can affect use, dimming the screen on large bright scenes. Beyond those standard OLED risks, the board flags unclear model-specific warranty and firmware support, which matters because firmware updates are how OLED makers improve burn-in handling over time. No hardware fault is recorded.

It provides enough bandwidth to run 1440p at 480Hz without display stream compression, which older DisplayPort versions cannot manage at that rate. The practical benefit is small, since compression is visually lossless, but it future-proofs the connection. To use it you need a graphics card with a DisplayPort 2.1 output and a cable certified for the higher bandwidth. On an older card the monitor still works over DisplayPort 1.4 with compression.
