Why are you considering an OLED for this use case?
Text will look terrible and burn in is a serious consideration. You'll get the edges of the windows burnt in in a few months time. Check Hardware Unboxed "purposely burning in" or something like that.
Please just grab 2 32" 4K for the same price as a 48" C4.
Source: I've put my 48" C4 on the desk. I can't work on it. Text sucks, pixel shift and ABL are noticeable and no, I don't want to turn them off via the service menu and void the warranty.
Interesting, I have quite the opposite experience with my 42" C3. I was very worried about the text clarity but I really can't complain about it. And I'm running 422 chroma sampling since I'm too lazy to switch off the 144 Hz framerate for working and then back again for gaming and have an old ass GPU with only HDMI 2.0. Haven't noticed pixel shifting or ABL either in practice but then again I run basically everything in dark mode.
Not saying that your experience would be invalid in any way, just saying that it seems to vary a lot personally how perceivable those things are.
Can't comment about the burn in as I've not had my setup for that long yet.
Hello, fellow programmer with one of these TVs checking in!
I've been using an LG C1 48" for the past 2.5 years for both work and gaming.
Mine is held 61cm from the front edge of my desk on an Ergotron HX arm (highly recommended).
For work and coding, I use MS fancy zones to portion the 4k screen into a 12 wide by 6 tall grid of equally sized subspaces. Dragging a window to 6wide by 3 tall makes it 1080p. 8 wide by 4 tall is 1440p. I can do custom tall/narrow for different applications, etc. I love it. Black desktop, AHK script to hide all desktop icons when I don't need them, auto hide taskbar, dark mode everything. I did most of those things before getting an OLED. Everything in Linux looks great, too.
I will say, for me, my 61cm depth is too close. I wish so badly that I could get the monitor another 20-30cm further away from me, but it seems like you have plenty of depth space.
With the depth you have, I would go for the 48". For anyone with a more standard 30-32" desk, I would urge you to go for the 42".
I'm building a new desk next year and it's going to be deeper so I can finally get this beautiful beast further away from me.
For me 30-32 inch depth is good for 42. I used 42c2 in such a desk. Now desk is 36 inch deep and looking for 48B4/C4.
