Fujitsu L22T-2 Refrash Rate Problem

[erdeminoff]

Hi. I bought a old L22T-2 monitor today and wanted to run this monitor 1920x180p 75 hz. But its seems only 60 hz from display properties. (Amd catalyst shows 75 hz to supported refrash rates but its not working) Also I dowloaded cru and patched clock limit my Amd R9 270x driver. In the beginning I used default 60 hz values from cru and set 1920x1080 70 hz. After restart Its seems 70 hz from display propertious but this time image not scaling correctly. So I think It should be from resolution parameters. SO I need correct parametres from best scaling. Here: Tecnical Details of L22t-2

Please help. Thank you

I don't know what you mean by not scaling correctly. The timing parameters are not for scaling. If the refresh rate is not displaying correctly, then either the monitor can't handle the refresh rate, or it can't handle the timing parameters you used. I don't have that monitor, so I don't know what refresh rates or timing parameters that monitor can handle. You have to figure that out. Have you tried the "LCD standard" and "LCD reduced" timing options?

Also, if you're using VGA, the auto adjust function in the monitor might have trouble with higher refresh rates. VGA quality also depends on the monitor, cable, and video card. It's best to avoid VGA with LCD monitors if possible.

Edit: Same parameters are working on 72 hz without problem

But i didnt pass blur problem. When increase refrash rate screen is bluring. I got max sharpness from 1080p 40hz. SO need a solution. I think maybe it ll resolve from vga connection. I want to try that :

What do you think?
