Unable to get other display resolution

Hello .

Have install the nvidia driver ( 295.49 ) manually ( the hard way which is not so hard ) on opensuse 12.1 ( Linux 3.1.10-1.9-desktop #1 SMP PREEMPT Thu Apr 5 18:48:38 UTC 2012 (4a97ec8) x86_64 x86_64 x86_64 GNU/Linux )

I have read :

I have a DELL E153FPT monitor which show :

Horizontal scan range 30 kHz to 63 kHz (automatic)
Vertical scan range 56 Hz to 76 Hz (automatic)
Optimal preset resolution 1024 x 768 at 60 Hz

I have a graphic card : NVIDIA 6800 GS which show :
Memory Interface 256-bit
Memory 512 MB
Memory Bandwidth 35.2 GB/sec.
Fill Rate 6.4 billion texels/sec.
Vertices per Second 600 Million
Memory Data Rate 1050 MHz
Pixels per Clock (peak) 16
Textures per Pixel* 16
RAMDACs 400 MHz

Is it possible to get any running display definition which Pixel Clock is under 78.8 MHz
such as :

cvt 1120 840 50

1120x840 49.91 Hz (CVT 0.94M3) hsync: 43.27 kHz; pclk: 63.00 MHz

cvt 1200 900 50

You mentioned that you have a DELL E153FPT monitor. According to the specs given here

DELL E153FPT 15-inch Flat Panel Touch Monitor : Point of Sale | Dell

your monitor is capable of a maximum (native resolution) of 1024x768@75Hz. What are you actually trying to achieve? You can go lower, but not higher with this monitor.

Factory Preset Resolution Modes	Image Brightness
720x400 pixels @ 70.1 Hz, 640x480 pixels @ 59.9 Hz, 640x480 pixels @ 75 Hz, 800x600 pixels @ 60.3 Hz, 800x600 pixels @ 75 Hz, 1024x768 pixels @ 60 Hz, 1024x768 pixels @ 75 Hz

I know that ( I give you all the data for that monitor. ).

I was just wondering as the max pixel clock is 78.8 MHz , may I use any resolution which shows a pixel clock less than 78.8 as :

cvt 1120 840 50
# 1120x840 49.91Hz  (CVT 0.94M3) hsync: 43.27 kHz; pclk: 63.00 MHz
Modeline "1120x840_50.00" 63.00 1120 1176 1288 1456 840 843 847 867 -hsync +vsync

which show a pixel clock of 63.00 MHz which is less than 78.8 MHz, with a hor. freq of 43Kh which is less than 63KHz and a vert. freq of 50 Hz which is less than 75Hz.

This is just my question.

It seems to me that I had have done something similar with my old CRT “VISION MASTER PRO 410” from IIYAMA; but I did not find my old config files.

But perhaps I misremember.

Thank you for your help but it is only a sort of electronic question. I would like to tweak my monitor when I use it for some work.

I is not a driver install problem.

I was just wondering as the max pixel clock is 78.8 MHz , may I use any resolution which shows a pixel clock less than 78.8 as :

No, of course you can’t. because the specs of your monitor show clearly that 1024x768 is the MAXIMUM (and native) display resolution by design. Your graphics card is capable of handling higher display resolutions and refresh rates, but your monitor will not operate.

Thank you very much to everybody for helping.:slight_smile:

Case is closed
