2 monitors, different resolutions capable of different hz'rates

[ailos]

I have a 144hz Asus VG248QE 1920x1080 monitor and a Philips monitor at 1280x1024 capable of 75hz.

Currently I am running them both with Dual Link DVI but for some reason my 144hz monitor locks down to 60hz while the Philips monitor still runs fine in 75hz.
If I disconnect the Philips monitor and only run my Asus one independently, I can get it to run at 144hz.
Can I not run different resolutions at say (1 monitor 144hz and the other one at 60hz) or is it some other issue?

The graphics card will only compute one refresh rate, so you are limited to the slowest rate displayable by both monitors

if clarkjd is right you could get a cheap gpu, 610 or something for the second screen? however it is managing 60 and 75 Hz simultaneously.

try it on displayport if you can, i'm wondering whether there is a combined bandwidth limitation across dvi.

I can run my Asus monitor at 144hz but then it forces the monitor to a 1280x1024 resolution, And also I tried to switch the DVI cables around and then my Philips monitor didn't even get a signal, The Asus monitor working fine at 144hz.

I think DP will fix that.

I think DP will fix that.

Will it make it so I can run 144hz and 75hz at the same time and optimal resolutions?

that I don't know. but dp can do 1440p at 144Hz, so it should solve the optimal resolution problem, I don't think that different frequencies are an inherent problem as you are already doing that.
