Oh this one will look good! A month ago I was struggling with even basic code reading (double text) so I embarked in a quest for the crystal clear text feeling that we need for programming and settled on this one:

It’s 144 Hz, looks cool, text is sharp and it can be found for 400$ too I think, so if even the one you found ends up being meh in text I’d suggest you 27” @ 4k

Now there are a lot of parameters when it comes to choosing a monitor but the bare minimum would be IPS, 1ms-4ms of response (no ghosting) and for me at least 120hz but it’s because I got used to it and everything else looks tacky/laggy
