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.

Lives up to my expectations!

Got a preorder after watching Monitors Unboxed review, which finally confirmed it was a good choice (I was upgrading from Dell Alienware 34 Ultrawide). The monitor lives up to the expectations - crisp colors, no font fringing in Win11 and excellent resolution. The only concern worth noting is that to fully enjoy 5k2k is to have a good GPU. I'm running 4090 and it's a stretch, so I need to optimize settings a bit more. No regrets and loving my new toy! P.S. I was worried that the curvature might be too much, but it's actually great and I wasn't expecting I would be enjoing so much!

5K2K Tandem OLED -Nice bright HDR Scenes-

[This review was collected as part of a promotion.] I've had this monitor for a month now. It has been amazing so far. The peak brightness is exactly what I've been looking for. When I was using LG's last gen WOLED. My main gripe was that the brightness for me was just too dim even at 100% brightness in the OSD and HDR set to maximum through windows. With the 5K2K Tandem OLED. It fixed all my initial issues with the last gen model. Ultrawide UHD resolution is sharp. Like looking at a 4k screen but with 39' length and the curve is so minimal and unnoticeable. Perfect for viewing. The matte screen for me is a plus. Since I work with a lot of LED lighting everywhere plus theres a big window in the room. 165hz is a nice refresh rate with this monitor too. It doesnt rely on DSC, so you get the full bandwidth of DP2.1. Although you need a GPU that supports DP2.1. The colors and contrast are your typical OLED popiness. The color stand out among whichever scene you're looking at and the dark scenes with black are really immersive. With HDR the dark scenes get even more jaw dropping. Since in small sections of the screen it can boost the brightness up to 1500nits without lossing any detail in the object. (Ex. A single light in dim dark room). For some people you may need to fine tune the monitor to your preferred settings. Once you dial it in to your specifications. You won't regret getting this monitor. As I've been interested in this monitor since it got announced. Before I pulled the trigger and bought it. I messaged LG support about a discount for the monitor in question. The Rep was very happy and sent over a code right away! So those of you who havent made a decision yet. Maybe that might entice you!

Just shutup and pay the money!

I am very pleased with this monitor. My previous monitor was a AW3423DW. The extra pixels, refresh rate, and screen space of this monitor is just wonderful. The only thing I am not so keen on is the AI upscaling. I feel a feature like this should be on a separate monitor thereby lowering the price. The main catch of this ultra wide oled monitor is the 5k2K resolution at 165 hz. You are going to need a 5090, or something close it, to run that resolution natively. Do not be discouraged by the matte panel. HDR videos on youtube show you of what this thing is capable. The matte finish is a plus because I now do not get reflections of my window or lights on this screen, while the colors and blacks make gaming a joy. Just buy it already.

5 Star Product!

If someone someone can leave a 1 Star Review without even trying the monitor then I'll leave a 5 Star. I own the 45 Inch version of the 5k2k monitor & it's amazing. I am debating on switching to this for the better panel but will wait on reviews. Everything about this looks great.

End Game Monitor - You want this one

I ordered this as a preorder and ended up getting it early. After 1 week of use, I love this monitor. Gaming, productivity you name it, this is the end game Monitor. I have the 45in 5k2k as well, that is a great monitor as well but the 39in takes productivity to another level The text clarity is great, colors are amazing, couldn't be happier

Dont

Size, brightness, colors and text clarity are really, really good. I returned mine due to HORIZONTAL banding issues. There were lines across the entire screen, visible when the image had a lot of light colors.. light grey, light brown, etc. Also, with white content, there was this almost sparkle effect I noticed.. not sure if this was caused by OLED tech or the matte coating. Just couldn't accept these cons at this price. Pic attached but it doesnt show the extent of the defect.
