45" is too big, I use an LG 42" TV and thats the absolute maximum size to comfortably use as a monitor, and even then I still need the display upscaled. 39" seems ideal, pretty much the same width but a bit shorter, the vertical pixels at the top don't matter at all.

This. Many of us are on 38" 3840x1600 screens that have been waiting years for an upgrade. 45" is way too big for me. Plus that 800r curve is terrible. I would've preferred 2000r in the 39", but 1500r is a lot better than 800r

The 45" is too big. 38/39" is the sweet spot for me. It covers my entire field of view. The smaller screen will also have higher pixel density. The 1500r curve will make it more versatile for gaming and desktop usage. I would've preferred a 2000r curve, but at least it's not a wild 800r.  Many of us have a 38" 3840x1600 screen that we've been waiting years for an upgrade.  I have the money, but monitor makers refuse to make the product I want.

I just setup my 39GX950B last night and played some Recsec. Coming from a AW3423DWF myself, its a really nice upgrade!

Yea I didn't think 34" -> 39" would be that big of a difference, but it feels way more immersive. The extra screen space with the extra curve is nice. I played a bit on my buddies LG 5K2K 45" before he returned it (Gave him bad motion sickness) and it was a bit too much for me.

I currently have the 45” 5k2k and might sell it for this one. 1500 curve sounds nice 👍

The curve is strong so your voice will sound like you're in a fishbowl lol. Reason im going to switch to the 39 inch.

My only hang up is it isn't glossy. I guess I'll wait another year before I move from my G9 oled.

I think this isn't really about which one is "better". It's simply a different form factor of essentially very similar monitor. I previously owned the 38GN950, which was an excellent display. For a long time, I was convinced that I'd move straight to its OLED successor as soon as one became available. However, the 45GX950A arrived first, and I figured it was at least worth trying. I was initially skeptical that 45 inches would be too large and that the 800R curvature might be too aggressive. That feeling did not last long. I adapted to the proportions fairly quickly, and now it feels just right. Now the release of the 39GX950B did not really spark interest for me anymore. I dont find myself wanting a smaller version anymore. I also feel that the generous 5K resolution and the level of detail 45GX950A provides are slightly better appreciated at this size. The PPI is still notably high, and scaling isn’t strictly necessary (though I personally use 125%). There's more of realistically usable workspace for productivity, and in games it's easier to admire the added detail that the higher resolution brings on a physically larger screen. Compared to traditional 4K 16:9 displays, these two are roughly equivalent in size to about a 37" and a 32" monitors respectively. That said, I completely understand that with different preferences, desk sizes, and viewing distances, the 39" model could be perfect.
