How can i force 60Hz for TFT Displays?

[sydney]

Hello

Ive be triad in xorg.conf but xorg doesent care and use allways 75Hz on each TFT, it looks like a blurry window.


xorg.conf

Code: Select all

Section "Monitor"
    Identifier	"SamsungTFT"
#    Option	"dpms"
    HorizSync 31.5-61.0
    VertRefresh 60-60
    DisplaySize 376 301
EndSection

Section "Monitor"
    Identifier	"ProviewCRT"
#    Option	"dpms"
    HorizSync 31.5-61.0
    VertRefresh 60-60
    DisplaySize 376 301
EndSection

Code: Select all

Section "Screen"
    Identifier	"Screen0"
    Device	"Nvidia0"
    Monitor	"SamsungTFT"
    DefaultDepth 24
    Subsection "Display"
        Depth 24
         Modes "1280x1024"
    EndSubsection

I know it seems a stupid question but are you sure the monitors accept 60Hz.


I've got to ask just to clear that up :], as for everything else, your xorg.conf appears good. So from here its beyond me

Search the google for "your monitor model xorg.conf"; it works wonders. I had the same problems with my SONY TFT and found the following solution:

Code: Select all

HorizSync   28-80
VertRefresh 48-75
ModeLine    "1280x1024" 108.0 1280 1328 1440 1688 1024 1025 1028 1066 +hsync +vsync

Here is what I have in xorg.conf:

Code: Select all

Modes     "1280x1024_60" "1024x768_60" "800x600_60"

This solved the problem for me.

I have solved.

The Option "VertRefresh" "60" is needed for nvidia drivers

Code: Select all

Section "Device"
    Identifier  "GeForceFX 5700 Ultra"
    Driver      "nvidia"
    #VideoRam    131072
    # Insert Clocks lines here if appropriate

Option "HorizSync"
Option "VertRefresh" "60"
Option   "UseEdidDpi"   "FALSE"
Option   "DPI"   "96 x 96"
Option   "DPMS"
#Option "RenderAccel" "true"
#Option "AllowGLXWithComposite" "true"
Option "Coolbits" "1"
