Cool name! However, I never had a situation with Goland where speed was an issue. In most cases, I'm waiting for the code to compile. Page rendering speed is an issue in things like web browsers. Besides, my main 4k monitor has a refresh rate of 30hz, so scrolling will always be janky...
For me, the killer feature of any IDE has always been integrated debugging and able to inspect the data. Integrated testing has also been another feature I cannot live without today.
I had to run a 4k screen through an adapter that could only do 30hz@4k and it was a horrible experience - I could notice the lag even when I was typing and scrolling anything was stuttering. I feel like my eyes got tired faster working on that screen. Why would you use that as a main display ?
I doubt it's going to damage your eyes. It's sample-and-hold, after all. It is just very tedious that you have to wait 33ms between when you type a key and it appears on the screen. You will notice, and you will be frustrated.
I have a 360Hz monitor and it is really amazing what the reduction in input latency feels like in the real world. All of this input lag that gets blamed on USB or bad input subsystems is really just double-buffered vsync.
I think that this article might be referring to the CRT displays (when the CRT gun would pulsate and cause visible flicker especially when the monitor was not interlaced). I do not notice any flickering with the LCD display. In fact, the text appears sharper when compared to another 4k monitor I have with a higher refresh rate... It's not the best though, but compared to what was 10-20 years ago it's amazing.
That said, it's certainly not for watching video or playing games.
Because that was the only 4k 28in I could afford. It's not the best I must say, but does the job. The monitor is massive, so I don't scroll that much anyway. I can have everything visible at once.
