Our take on the LG UltraGear 27GX790A OLED Gaming Monitor
The LG UltraGear 27GX790A is a 27-inch 1440p OLED gaming monitor built for fast play. Its OLED panel delivers near-instant pixel response and deep blacks, and LG rates peak brightness at 1,300 cd/m² for punchy highlights. It sits at the top of the 27-inch 1440p class, trading the higher resolution of 4K rivals for speed and contrast. It suits competitive players and anyone who wants OLED picture quality on a desk, though burn-in care and static desktop use are worth weighing.
- OLED panel gives essentially instant response and no smearing
- Deep blacks and high contrast beat any IPS or VA rival
- 1440p at 27 inches keeps frame rates high without a top-tier GPU
- 1,300 cd/m² peak brightness makes HDR highlights stand out
- HDMI and DisplayPort cover PC and console sources
What reviewers say

Questions and answers
- Is this monitor good for competitive shooters?
- Yes. OLED response and a high refresh rate keep motion clear, which is why fast-game players favor it. A strong GPU helps you reach high frame rates at 1440p.
- Should I worry about OLED burn-in?
- It is a real long-term risk with static elements like taskbars. Use screen-shift and pixel-refresh features, hide the taskbar and vary content if you also work on it.
- How does it compare with a 4K gaming monitor?
- It is faster and has better contrast, but 4K is sharper for desktop work. Choose this for motion and HDR, 4K for text and detail.
- Does it work with a PS5 or Xbox Series X?
- Yes, through HDMI. Consoles can drive 1440p output, though some features depend on the console's supported modes.
- What is in the box?
- Expect the monitor, a stand, and HDMI and DisplayPort cabling. Check the listing for the exact cables included.
- Is 27 inches too small for 1440p?
- No. 1440p at 27 inches is a common, sharp-enough pairing and keeps frame rates higher than 4K.
