eye problems and monitor refresh rate

Is it possible to use higher refresh rates than 60hertz, when you install Arch and use it (without GUI, just command line)?

If I have understood right, the default refresh rate for pretty much everything is 60hertz.
It's impossible for me to do anything with that refresh rate, it begins to hurt my eyes almost immediately.
It has to be at least 75hertz.

Re: eye problems and monitor refresh rate

Judging by your comments I'll assume that you're using a CRT display. If so, the obvious example to help with your eye fatigue would be to buy a LCD monitor. If you are using an LCD, then the refresh rate should be 60Hz and increasing it will NOT make a difference. The native refresh of all LCD panels that I've seen is 60Hz.

Re: eye problems and monitor refresh rate

it depends what videocard you have, you'll need to compile a kernel which includes the framebuffer driver for it (intelfb, radeonfb, nvidiafb) and specify something like "video=radeonfb:1280x1024-32@75" as a kernel boot option

see here for ati radeonfb

and the intelfb documentation is here

google around for nvidiafb
