LG UltraGear OLED GX9s SMART Gaming Monitor 45GX90SA-B - WOLED UWQHD 1440p Curved 45 Inch, 240Hz, 0.03ms, HDR 400, webOS AI, Speakers, Wi-Fi, Bluetooth, DP 1.4, HDMI 2.1, USB-C

Brilliant monitor and a great upgrade from the previous 45" Ultragear. Doesn't support as high refresh rates but this is a small trade off for getting the full WebOS.

The build quality feels premium at first, but a few issues let it down. The stand is noticeably wobbly, especially with the monitor raised to its max height - any knock on the desk makes the screen visibly shake. The resolution (3440x1440) is a real limitation on a 39" screen; text and fine detail look soft, and it's something to be wary of at this size before buying. The webOS smart software is also hit or miss - I found it laggy and prone to glitches, and it repeatedly prompts you to switch inputs whenever you connect a new device, which gets old fast. For anything beyond gaming, like watching films or TV, the screen size doesn't translate well given the resolution - text and UI elements can look stretched or blurry. I'd also flag that LG lists Picture-by-Picture/Picture-in-Picture support in the specs, but several buyers (myself included) have found this feature isn't actually available on this model - worth checking before you buy if that's a dealbreaker. Great panel and colours when it's working well, but these issues hold it back from a higher rating.

An amazing monitor. LG panels are the best. This OLED is crystal clear with dark blacks. Was a bit fiddly to set up due to all the different settings but once done it’s stunning. Is an aggressive curve however it hits your line of sight perfectly. Great for productivity and fantastic gaming to boot

I bought this 39" ultrawide to do it all. Attracted to the deep blacks of an OLED, and the size was about what I was after. It seemed to hit all the spots. Firstly the good. For 1st person games, it's phenomenal. The immersion people talk about is true. The curve brings you in, you can focus on everything on screen and everything off screen does seem to disappear. It really is impressive here and where the monitor excels. If you spend the majority of your time on this activity, I'd recommend this monitor. For non 1st person games, like strategy games, 3rd person views, isometric view based games, it's still very good. The colour rendering is wonderful, response time fast, etc. The only negative is some text clarity isn't quite there, but that's going to be font dependant on the game. I'd still recommend with that caveat. The smart TV capacities, I didn't overly explore, but it seemed very comprehensive. Bear in mind with the curvature though, the usage of the monitor is limited to you sitting in a very exact place. With your eyes being 80cm away from the screen being that exact place. If you even lean back a little, or too the side (apparently I do this a lot leaning on my chair, something I never even thought about before with flatter screens), the image starts to appear to be a bit contorted, and drops the enjoyment of whatever media you are viewing. Sit in the exact space though (easier with 1st person games as previously mentioned, but less likely with a movie), and it's fine, and the 21:9 format works very nicely. So why the 3 stars then? Because I don't just watch movies sat 80cm away and play games. I like to have a few things on screen at once, a browser in one place that I tend to read, a youtube movie to the side, a calendar and note taking somewhere reachable too. The size is great for this, the curve is too aggressive for this, the OLED tech unfortunately is poor for this. The text clarity is the real reason why I chose to return this monitor, the underlaying subpixel layout resulted in text fringing and I also deal with highlighted text at work, we tend to use yellow highlight, and this resulted in the left side of the highlighted text being green, and the right side in red. Very odd and distracting and something I never came across with an IPS screen. A few fonts seem fine, but many just weren't. Ironically the LG website seemed to use one of the worse fonts for rendering on an OLED too. It was way worse than my 10 year old 32" 1440p 2k IPS 60Hz screen to an unacceptable level. Spreadsheets are just weird too. They say sit in the perfect space and it appears to be straight. OK, but flatter monitors are always straighter anyway so this isn't an issue. 800R is honestly just a bit crazy for productivity tasks, there is nothing else as aggressive as this curve on the market. It also eats a lot of desk space up due to this, even with a large desk like mine, plus the large stand brings the monitor about 12cm closer to the back of it, which is quite significant but probably necessary to get the user of the monitor to adjust to that 80cm sweet spot. If you're on the market for a monitor, and have more than 10% of your time not gaming, then I'd unfortunately recommend looking at a different model. Other things: The backlighting is quite nice, the menu system a bit confusing, and the processor is not fast enough for the smart TV things. It's a nice to have (maybe suitable for a student that's just left home) but cheaply done. This results in booting up time being fairly significant (10-15 seconds), and when plugging in a new input source, it seems to take a while to recognise this, and then offers to switch source, or sometimes not even that. Maybe this was a menu option I missed though.

Colour excellent, peripheral vision takes some getting used to and the settings confuse me but I am almost 80 years old.

Very happy with those screen glad I didn't buy the 45 inch version

Don't buy LG monitors they install bloat spyware on to your Windows computer without your permission and then track and sell your information. Google if you don't believe me!
