Vivid

[This review was collected as part of a promotion.] All I have to say about this monitor is just WOW! I had an LG 1440p 144hz nano IPS before and I got this as my main and its so much more vibrant! Amazing for gaming!

Blown away

[This review was collected as part of a promotion.] Just picked up the LG 27GX704A-B and I'm honestly blown away. The glossy finish on this screen makes the image look so much clearer than my old matte monitors. 1440p at 240Hz is the sweet spot for gaming right now, and the motion clarity is unreal. No ghosting, no blur, just pure speed. Highly recommend for anyone looking to level up their setup!

27” OLED ULTRAGEAR - SUPERB!

[This review was collected as part of a promotion.] I recently swapped my studio monitor from an LCD to this OLED and the differences are highly noticeable. No longer experiencing mouse lag due to the screens high refresh rate which is so much nicer to work on. The picture looks crystal clear with brightness and colour looking on point. The monitor assembles easily to the stand within seconds and the screen looks great in my studio. Bigger isn't always better as I found my previous 32” slightly too big which was straining my eyes but the 27” is perfectly uniform for the distance I am sitting from the monitor. I may have spent a little more than I intended but the upgrades are well worth the additional cost. I'm very happy!
