Spyware

You pay a lot of money for a monitor that installs Spyware on to your machine as soon as you plug it in. BEWARE: LG is stealing everything it can, will ruin your gaming experience with Spyware, and charges you an insane price while they do it.

Awful Panel

That Matte finish ruined the panel, OLED Must be Glass not this, picture in SDR looks similar to an IPS monitor, Horrible! HDR looks better but I need to consistently run the OLED Pixel Clear feature otherwise some shapes will appear on screen, overall I am totally disappointed with my purchase and I am not happy at all with this, wish I knew how horrible this monitor, Stay away.

Terrible picture quality

I upgraded my 32" monitor expecting better quality, or at least some improvement, but it hasn't turned out that way. I've spent hours adjusting settings, watching tutorials, and trying different configurations. While the colors do look better, the overall clarity and detail just aren't there. No matter what I try, nothing seems to fix it. At this point, I'm honestly regretting the upgrade.

45GX90SA-B

[This review was collected as part of a promotion.] The LG 45-inch OLED monitor is absolutely stunning. The ultra-wide screen delivers incredible image quality with deep blacks, vibrant colours, and excellent contrast. I used it for both productivity and gaming, both performed amazingly, with smooth performance and plenty of screen space. The build quality feels premium, and once you use OLED at this size, it's hard to go back. I would recommended to anyone looking to upgrade their experience.

Amazing monitor!

This monitor does it all. Great for pretty much everything on the planet. Doesn't glitch or have any issues. Can connect via USB-C or HDMI.

Really worthy purchase

[This review was collected as part of a promotion.] Really good graphics, good response time and refresh rate. Bought for gaming and some other uses and there is no lagging, just good vibes. 10/10 would recommend

Miss leading false advertising.

This monitor does not have PBP or PIP mode as stated in the specs. It will only display 1 input and one web based screen at the same time. Not split screen from 2 different computers using 2 different inputs.

Gorgeous Image, only one flaw

The monitor has a great picture on it. Much like the previous model 39GS95QE-B.AUS. WebOS is ok for my first time ever using it. Although WebOS has more features and functionality, I think the settings in the previous model were easier to use and find. My biggest issue is I cannot get the monitor to go in standby mode and do a pixel clean on its own. Contacting LG was no real help as they initially told me it didnt have a standby mode. I had to take images and show the guy it did. Every time it has inactivity, it says no input, attempts to go in standby and then comes back out and starts the no input again. This is the same across three systems. I even tried to turn off the network on the monitor and unplug the current selected input to see if that would help. It did not. I had no issues with the previous model going in standby and cleaning itself. Hopefully they get this fixed soon.
