Very happy with my single LG Monitor 38UC99-W. I can have multiple apps up including a mind boggling 2 foot wide waveform edit window.
IMO, 38" 3840x1600 IPS is the sweet spot for work + gaming. I've been using a discontinued LG monitor for the last 5 years and have been very happy with it.
I have a 38" 3840x1600 monitor (same aspect ratio), that I've been using for work and gaming for the last 5 years and absolutely love it!
IMO, do yourself a favor and look at some 38" 3840x1600 resolution IPS monitors. The higher pixel density and standard subpixel layout should make reading text easier on the eyes. Also, the Odyssey's higher pixel count should require a more powerful GPU to achieve the same frame rate. My understanding is that most competitive FPS players opt for 1080p or 1440p, to max their FPS, which would be even more reason to lean towards a 38" monitor if you really want something that big. I say this as someone who debated between a 40" 4k monitor and the size and resolution above, and ended up going with the LG 38" monitor in 2020 and having no regrets. I've primarily used it for work on my MBP and gaming, with open world survival/shooters being my favorite genres.
I think LG has a relatively newer version of 38" in IPS. It's the W model. I've worked on both 34 and 38 ultrawide and the 38 is way better. You really grow to appreciate the extra vertical height that 1600px gives you.
I absolutely love my 38" LG (I have the Freesync version). However, I don't see it for sale anymore. I feel 38" is the perfect size, though I suppose a higher resolution would be good. Why not consider the 38WR85QC-W.AUS? It's basically the same as the 38GN except cheaper ($1200). The 40" 5k 2k is also a good option, but I use my UW for both work and gaming so I'd go with the 120hz one.
The same panel is used in the LG 38" widescreen monitors. I'm having one of the Lg with freesync instead of g-sync
I have a 38" 3840x1600 with a 2300r curve. It's fantastic. Perfect size. That 39" looks great, but that 800r curve is far too aggressive. I need to be able to use it for non gaming too.
