Does it all.

[This review was collected as part of a promotion.] Brilliant display, 45 inch curved ultrawide is next level immersion, comes with webos which works well and a remote for ease of use. It has LG TV style HDR, making good use of the 1300 nit panel spec, which makes everything look better and adds that punchy wow factor to the image. Built in speakers work well and honestly the best display I've owned to date!

Beautiful monitor

I come from a pair of 24" 2K IPS monitors and I'm loving the physical size and 5K2K resolution of the 39GX950B-B. Whether I'm consuming media, playing games, editing photos or video, or doing productivity work, I don't feel space constrained - even vertically, which was a sticking point for me with many ultrawides. I love the non-gloss anti-glare coating since it's in a bedroom with lights and windows. Image quality, color reproduction, and contrast are fantastic to my eyes, and I'm loving the HDR effect for my photos. I can't wait to try some games with HDR support as well. I also appreciate the clean physical design of the screen and stand.
