It is theoretically possible over VGA and HDMI v1.3+, but that does not mean it's actually supported by the hardware.

yes it's possible on low resolutions

HAROOOW

with hdmi v 1.4a? i heard only hdmi v1.4b can get 120hz , but my videocard has hdmi v1.4a

On lower resolutions any version is enough to get 120hz

you should be able to get 120hz at 1080p on hdmi, it can handle 4k at 60hz

my VG236H begs to differ

you need hdmi to hdmi, adaptor convert everything to vga and no actual talking between card and monitor happens

if its 120hz in the specs then thats the max refresh rate at the spec max resolution in todays world of buying monitors and LED pride panels

CRT were like max res : 1600x1200
max refresh 80000hz

max refresh you could only get at 320x240

hdmi v 1.4b can get 120hz, but my laptop videocard supports hdmi v1.4a so i caont get 120hz?i can get only 85hz with vga i guess rip

Depends on the monitor & the drivers ofc.

VGA can do 1600x1200 @ 100Hz. 120/144 is no problem when hooking up to an old CRT. I imagine Hdmi or any modern interface is capable of handling 120Hz and above at lower resolutions.

The main/real question is whether it's been made part of the requirements spec for the interface (therefore drivers produced to comply with spec).

Iirc hdmi is effectively a repackaged DVI with audio, and dual DVI can handle 120Hz no problem.

Check your laptops GPU model/chip and hop over the manufacturers' website, you should hopefully be able to find a list of officially supported resolutions/Hz.

Ultimately my friend, you just have to do the research to confirm it yourself otherwise you may be wasting money/time on something that is destined not to work. Good luck!

Friend has same monitor that i want to buy Benq XL2411Z, so i think i will go to test with my laptop....

Makes sense. Hope it works np for you!
