I'm just letting you know I also returned my Gx9, bought a G5 55" for a cheaper price and have not regretted it once. The G5 is just on another level compared to the GX9. The brightness, the colors, the color saturation and even the screen coating is spectacular compared to the dull picture you get from a Gx9.

I picked the exact same monitor and I am typing on it now. It's clear as a bell. I didn't want the stupid built in OS so this was better than last years model. I bought this for gaming and after watching a few reviews about the 5k2k not scaling well for lower resolutions I bought this because I can actually run games in the native resolution without upscaling. With the 5k2k I was planning on just scaling down to 3440x1400 anyways but happy I just bought it native. Super happy I did. It's basically a perfect match for my system (Ultra 265 + RTX 5070). I also got a smoking deal on this monitor. If offered a 5k2k for trade on this one to one, I don't know if I would even do it, I have the resolution I want with no scaling and 240hz native instead of 165hz.

I had this same debate and I went 45”, the monitor not being tall enough was my biggest complaint with a 34” Ultrawide. I wasn’t gonna go bigger unless it was taller. 800r is aggressive but I don’t mind it at all.

Purely for sim racing? I’d go the 49 inch for sure. You don’t need lots of vertical FOV but you do want lots of horizontal FOV. I ran a 21:9 and a 32:9 for racing and I’d pick the 32:9 anytime if u can’t run triples

Personally I would avoid an 800/1000R curve (The LG GX45) for productivity unless it doesn’t matter to you that timelines and shapes aren’t straight.

AW3821DW owner here. I got the GX9 last week and going to return it because of the curve. It doesn’t feel right when doing work and I also find hiding task bar annoying. Shame as it’s amazing when gaming.

I have an LG Dual Up (2560 x 2880) next to my new GX9 and the text looks better on the Dual Up. Pretty disappointed.

Awesome, I’ve been looking forward to this since the moment it was announced. I’m very intrigued by the new AI features and the text clarity/increased brightness of the new tandem panel. I had the 45” for a few weeks but the curve was too aggressive for visual work. Fantastic for gaming though. Hoping this will bring the best of both worlds to my use-case (75% WFH Creative Director / 25% gaming). [Current setup with the AW3821DW](https://www.reddit.com/r/battlestations/s/vizki55jMh) - Looking forward to adding an OLED next to the DualUp!
