    A nice upgrade from C2 OLED TV

    I just upgraded my primary monitor to this "LG 45GX950A-B" (sometimes called "GX9" for short). Previously I was using an LG C2 OLED TV, so I will be comparing against that.[Text Rendering / Subpixel structure]The GX9 has a subpixel structure of "RGWB" (red-green-white-blue) which is better for sharp text rendering than most other OLED displays to date (including my C2 TV). This is because much text in major operating systems uses subpixel antialiasing which is normally tuned for an "RGB" subpixel structure. When the physical display panel differs from that, it causes color fringing around text

    Absolutely incredible monitor for gaming and daily use

    I have been extremely happy with this LG 45 inch UltraGear monitor. The size is perfect if you want something immersive without going to a full triple monitor setup, and the picture quality is honestly stunning. The OLED panel makes games look rich, sharp, and smooth, with deep blacks and great color. The curve feels natural and really pulls you into whatever you are playing.Gaming on it has been excellent. The motion is smooth, the response feels instant, and it pairs really well with a high end gaming PC. Racing games, shooters, and open world games all look amazing on this screen. It also w

    Great Panel!

    Love it. The screen real estate is huge. You can have three tabs across the screen during multitasking and it stays very usable. I personally wouldn’t recommend going any wider than this panel like some Samsung screens do. Any wider and it feels awkward to look at the left and right corners of the screen. This is a nice sweet spot for multitasking while also fits media like films fit better.The fact this is an Oled panel and 5k2k is the cherry on top. Unless you’re paying for a 6k screen this seems to be the best DPI that you can get at a reasonable price.One issue I did have is the dual mode.

    This monitor is amazing; pros/cons for non-professional users

    I've been using it for 4 months now and when I first set it up, it was stellar. The difference was incredible. It's very immersive and just a great screen. I'm not going to go into all the details that others do, but I'll highlight a few things:Pro:- It's big. The curvature is just about right if you're about 3 feet away.- The HDR is a nice change and very noticeable.- Refresh is fine - 165Hz is more than enough if you can push it there.- 2 HDMI, 1 DP, 1 USB-C is nice.- I get 165Hz with both DP 3M (what is now Green Jiss CABLE-54532587 (?)) and HDMI 2M (Ubluker UB222) cables from Amazon.- USB-

    Genuinely great monitor. Don't buy it unless you like ads and spyware.

    Probably the best gaming monitor I've ever owned. Wanted to upgrade from an Alienware DW34 OLED to this. Don't buy it if you own a Windows system, or LG's products in general right now.On Windows systems, this LG product will piggyback an installation through Windows updates that will download literal adware and spyware to your device without your consent or knowledge, giving you ads for things like McAfee directly to your computer, and being able to track your inputs and (in the case of their Smart TVs) listen to people around it to sell that data to whoever they want, possibly in violation o

    Damaged in transit or manufacturing defect? UPDATE

    Received my LG 39TX90SA-W after 8 days between time of order and delivery as part of the Amazon Prime Day event this summer. Item arrived in good condition without any apparent damage to shipping and product boxes. However, upon setup, my monitor had noticeable vertical banding on the left half of the screen, especially on gray backgrounds. Perhaps the damage could be attributed to the jostling of the shipment in transit? The box is large and is not light. Would’ve returned it and requested a replacement through Amazon, but the monitor was now 2x the price I bought it for, and return/replace w

    Amazing upgrade for everyday work & gaming

    Before your read this review, I am not a super serious gamer. I bought this monitor mostly for work and to play non-fps intensive strategy games like EU5. Eye fatigue, screen real estate, and resolution quality drove me to splurge on this monitor, and I am so glad I did. This monitor is insanely good and worth the price.I had an 49in UW Odyssey G9 before but this 45in Ultragear is leagues above that in almost every way. Resolution, screen real estate, ergonomics are all much better than any UW or even Apple monitor.First, the resolution makes a massive difference for someone like me who stares

    beautiful monitor. good pixel density for desktop use. absolutely shines when playing games

    pretty crazy monitor... for a pretty crazy price. ive replayed every game i have with it and its everything i wanted. 4k and ultrawide and oled and bigger then my last. this wraps around you thats not annoying like the G9 from samsungmy cons are the fact that the stand is a grey ish with just a slight tinge of blue tint. kinda odd considering most setups are black white or a certain color or have a wood estheticand a huge con is a "2 year warranty" i had to call amazon and lg to verify this because nowhere is it listen. thats why i loved my DWF alienware monitor that had a 3 year burn in warra
