skull_noose Posted January 5, 2004 Report Share Posted January 5, 2004 Hey I was wondering if anyone could help me? I can't figure out how to change my refresh rate on my monitor. I am runnning Mandrake Linux 9.0 with a Nec 17" monitor. Your help is greatly appreciated! Thanks! Quote Link to comment Share on other sites More sharing options...
Andrewski Posted January 5, 2004 Report Share Posted January 5, 2004 skull_noose, According to http://www.mandrakeuser.org/docs/xwin/xset.html, Mandrake should automagically pick up what monitor you're using and select a refresh rate. If that's not good enough, looks like you'll have to edit your XF86config file manually. That's the file that determines your display configuration, e.g. video driver and monitor config. Are you experiencing problems/flicker? What monitor are you using? Quote Link to comment Share on other sites More sharing options...
chris z Posted January 5, 2004 Report Share Posted January 5, 2004 if i'm not mistaken (can't verify this 'cause i'm at work) you can also change the refresh rate in Mandrake Control Center->hardware->monitor. it should give you an option to test the settings you choose before applying them. then you must reboot (or at least restart X) for them to take effect.

skull_noose Posted January 5, 2004 Author Report Share Posted January 5, 2004 when my heater or air conditioner comes on the screen flickers for about 30 seconds....then it resets. i had the same problem with my other machine running windows xp..set my refresh to 60hz and it was fine.....im not real sure how to manually set it.....any tips?

Andrewski Posted January 5, 2004 Report Share Posted January 5, 2004 Chris, nope, can't change the refresh rate in MCC, only the colour depth and the resolution. (I thought the same thing but could verify it. :)) As for the heater, I think that's to be expected if it's messing up the workings of the monitor. Not sure though. What kind of monitor are you using? Quote Link to comment Share on other sites More sharing options...
ac_dispatcher Posted January 6, 2004 Report Share Posted January 6, 2004 I have modified my refresh rate by adding a "modeline" section in my XF86Config-4 file: in my XF86Config-4 - Section "Monitor" Identifier "monitor1" VendorName "Generic" ModelName "Flat Panel 1280x1024" Option "CalcAlgorithm" "CheckDesktopGeometry" DisplaySize 320 240 HorizSync 31.5-67 VertRefresh 50-160 Modeline "1280x1024" 843.85 1280 1704 2720 4656 1024 1024 1032 1132 +hsync +vsync EndSection Notice the "modeline" part. Its sets my refresh to 160hz. You can get setting with a modline calculator. Try this one: http://www.hut.fi/Misc/Electronics/faq/vga...a2rgb/calc.html Hope it helps.

Qchem Posted January 6, 2004 Report Share Posted January 6, 2004 You could try using xvidtune - but be carefull. If you break anything you own the pieces :P Quote Link to comment Share on other sites More sharing options...
iphitus Posted January 6, 2004 Report Share Posted January 6, 2004 When i turn my deskfan on whe it's hot, the screen looks like its running at somethin like 10hz coz of the vibrations. ANyway im ot. 60hz isnt good for your eyes, i run at a lower res 85 hz and it's much nicer on the eyes. i dont get sore eyes after a while.

coverup Posted January 8, 2004 Report Share Posted January 8, 2004 xvidtune is a great tool. As Iphitus suggested, I run my system at a lower resolution (1152x864). X config tools pick up 75Hz refresh rate at this resolution, which gives some flicker. Using xvidtune I found a modeline for 78 Hz, and the flicker's gone. Interestingly, I couldn't find 85Hz modeline though the monitor happily accepts 85Hz under Windows. Quote Link to comment Share on other sites More sharing options...
aRTee Posted January 9, 2004 Report Share Posted January 9, 2004 I guess you may have to play a bit more, if win can do it, lin can do it. In my experience, with linux you get one small resolution step more at the same refresh rate, or at least the same, in linux, compared to windows. Also, linux often allows higher resolutions than windows, esp on somewhat older hardware. Quote Link to comment Share on other sites More sharing options...

skull_noose Posted January 10, 2004 Author Report Share Posted January 10, 2004 Where can I get XVIDTUN? Thanks for all your help! You guys rock! Quote Link to comment Share on other sites More sharing options...
coverup Posted January 10, 2004 Report Share Posted January 10, 2004 Where can I get XVIDTUN? Thanks for all your help! You guys rock! It's xvidtune (all lowercase). It is the part of XFree86 AFAIK. On my computer, it resides in /usr/X11R6/bin/xvidtune. Before doing anything, make sure you read the manual: [user@host currentdir] $ man xvidtune Remember the warning: You could try using xvidtune - but be carefull. If you break anything you own the pieces Quote Link to comment Share on other sites More sharing options...
