LG ultra gear Evo 45 inch 5K2K OLED - I wasn’t sure how good this monitor would be until I turned it on connected it to my 5090 pc I couldn’t believe my eyes

Arad84Oct 16, 2026 · Verified purchase ★★★★★

Best gaming immersion - I upgraded from the 39GX950B to the 45" and haven’t looked back. Gaming on this is on another level, and the immersion is what sold me. Text is a bit softer than the 39", but it’s very usable. Brightness is good, the colors are deep and not washed out, and the matte finish is great in a bright room. One note for anyone who gets this monitor. Mine had visible vertical gray banding right out of the box, with zero hours on the panel, which scared me. That doesn’t mean yours is broken. I ran the pixel cleaning from the monitor’s menu once, and the banding was gone. Ten days in, it’s still clean, even on gray test screens and in dark scenes in games. Try that before you return it. LG says panel uniformity varies from unit to unit, so results can differ, but it worked for me. I also leave it in standby after sessions, not powered off, so the automatic cleaning cycles can run. Highly recommend, especially if you game.

Best monitor I have used so far - Used this on a Mac mini and it works great!! Refresh rate is amazing and the OLED provides perfect image. I would highly recommend this monitor. Make sure you have the proper cables to connect to Mac as not all cables can handle the high refresh rate.

GINORMOUS CURVED OLED FOR GAMING - Having owned a lot of different versions of LG Ultragear monitors over the years, from LED's to Oleds ranging from 400 to 500 HDR, to now this monster screen. I was a little hesitant to how this one would perform, being a curved dual mode 5K2K seemed a little weird at first, but ..it works. On one side of the spectrum you have this beautiful 5120x2160 165Hz OLED HDR400, perfect for casual games (think Cyberpunk 2077 with ray tracing, or Red Dead 2) absolutely stunning; Then at any given moment you can hit a button and change it to a 2560x1080 running at 330Hz for lightning fast gaming at .03 GtG almost too perfect for fps games such as Valorant or playing some Eternal Doom, racing games etc... Pros Immersive 45" ultrawide *800R Curve Beautiful OLED give you great visuals and perfect blacks - with a contrast ratio of 1,500,000:1, and a color depth of 1.07B Fast even at 5120x2160 (165Hz), but if you need to easily switch modes to 1080 for 330Hz - Insane response times (.03 GtG) PBP (Picture-by-Picture : 2PBP (side-by-side from two inputs) -PIP (picture-in-Picture): Adjustable size/position, screen/sound switching DP 2.1, HDMI 2.1, and USB-C 90W Cons -It's a bit on the expensive side -With all OLED's there is a risk of burn in (suggest using pixel shift, screen savers, and hide your taskbar w minimize) -Speakers are 7W, not quiet but also not very loud, but to be honest I wouldn't personally ever use a monitors speakers anyways, but you also have a choice of using a headphone jack that is directly under the screen if you need more options..., but honestly if you own this monitor you must likely are already using a separate headset. -Very large power brick ...and just to be frank, This monitor : It's a monster, it takes up a lot of desk real estate, If you have a small desk, consider an arm or perhaps going down to the 39GX950B-B size/model. Overall, this is a great monitor, if you have the desk room and are wanting something to really get you feeling like you are in the game, get this monitor. I have been having a blast so far, there are a lot of features to this monitor, I have been tinkering for days changing settings and testing thing out, it wasn't until day 3 that I realized I could setup multiple configurations of the PBP&PIP which has been fun to play around with. The monitor is fast, beautiful and worth it if you are looking for something like this, I would definitely give it a shot if you are in the market.
