I just run on a 45" TV at 3840 x 2160. Sure, the response time is slow for gaming, but it works fine for movies and coding. And I have enough space that I can set each window to whatever size and orientation I want.
Previously dual monitor, 24" 1920 x 1080, portrait left, landscape right. left was usually for email and chat, right for coding and browser.
Now it's a single 40" 4k tv as my display. Using gridmove to easily partition the screen as needed. It's like have 4 1080p screens with no border. Only downside I've come across is some screensharing apps will always share the entire desktop when sharing a single app (webex is worst offender) - just the app window will be shown, but with massive greyed out background. Can be fixed by changing desktop res, just an annoyance.
Moving to a single massive screen has honestly lead to better productivity, but i possibly attribute that more to gridmove than overall screen real estate.
I fix that by maximizing whatever app I'm sharing and upping the zoom. It looks comically large on my screen, but normal to the rest of the folks on the call.
For screen sharing I use Picture-in-Picture mode of my 43” 4K monitor (Acer DM431K) to give me a separate 1920x1080 screen to share when required. That way it is at the right size and resolution for everyone.
Yes. One HDMI 2.0 to give me 4K@60Hz and then one usb-c to HDMI (or is it DP) for the PiP.
Only one input on this specific monitor can do 4K@60Hz, all the others are 4K@30Hz or good refresh at lower resolutions.
Takes 20 seconds to enable the second display in display settings and then pick the right input for the PiP mode on the monitor (it has a remote). Most of the time I have my personal laptop displaying in the PiP frame lower right. The remaining 3/4 of the screen is my work area.
I used a 40-or-so inch med-to-low tier TV for coding a bit, and was surprised at how not terrible it was. The latency was not actually that much worse than a monitor.
This was in the living room, which is sort of inconvenient. So I decided to get one for my desk. Being a silly project just for myself, I didn't want to splurge on it, so I went for the cheapest 4k I could find. I think it may have been a store brand.
The response time on that thing was noticeably terrible, like I would lose track of the cursor in vim because it wasn't keeping up properly.
The moral of the story I think is that you can get a not-terrible 4k tv for coding reasonably cheap, but the response time issue may still exist. It is probably just a roll of the dice.
