I've used 43" for 3 years now
I bought a 4K LG TV with an HDMI 2.1 input. Problem solved for £265 (Argos end-of-line sell-off)
I can fit 8 A4 pages on the screen at full size (just a few lines lost off the top of the top row of 4 pages), which is excellent for 3-way code merges.
Rock solid display with no flickering or colour/brightness variation.
The only problem I have is when I screen share with colleagues on laptops, and I have to make the text ridiculously large on my screen for them to be able to read.
