Blurred image, v10 x86, dual screen, ATI, laptop.

[kebabbert]

I got a blurred image on the external TFT screen, why is that?
----------------------------
Ok, I got everything working now. A Dell Laptop D600 with ATI mobility Radeon 9000 running dual screen, internal 15" 1400x1050, external 20" TFT 1680x1050, on Solaris 10 x86. Thanx very much for your help!

What I did to get different resolutions working, was that I looked into /var/log/Xorg.0.log file, and added those numbers into the "Monitor" section:

...
(II) RADEON(0): Supported additional Video Mode:
(II) RADEON(0): clock: 146.2 MHz Image Size: 433 x 270 mm
(II) RADEON(0): h_active: 1680 h_sync: 1960 h_sync_end 2136 h_blank_end 2240 h_border: 0
(II) RADEON(0): v_active: 1050 v_sync: 1053 v_sync_end 1059 v_blanking: 1089 v_border: 0
(II) RADEON(0): Ranges: V min: 56 V max: 75 Hz, H min: 31 H max: 83 kHz, PixClock max 170 MHz
(II) RADEON(0): Monitor name: 20WGX2
....

transforms to:
ModeLine "1680x1050" 170.00 1680 1960 2136 2240 1050 1053 1059 1089




However, there is still a problem. On my external 20", the image is slightly blurred. The font are not razor sharp, which it is on my laptop screen. Maybe the problem is specific for Solaris?
