Refresh rate
Posts: 6
Hello everyone,
I am having difficulties to set the refresh rate of my Samsung LCD monitor with Nvidia for Mepis 6.5 RC 3
[eVGA GeForce FX 5200 256 MB AGP8x | Samsung SyncMaster 173T ]
I followed the instructions on this forum and wiki also. No luck!
If I use the vesa (xorg) driver (Mepis X-Windows assistant) to repair the xorg.conf, I have 1280x1024 at 75 Hz. which I want but I cannot use Beryl.
If I use the nvidia (new) driver (Mepis X-Windows assistant) to repair the xorg.conf, I have 1280x1024 at 53 Hz. which gives me Beryl but lower refresh. (At this refresh rate, my eyes get strained quickly)
If I add the following line and clean up the relevant code in nvidia based xorg.conf, it does not make any difference:
# V-freq: 75.00 Hz // h-freq: 80.42 KHz
Modeline "1280x1024" 151.83 1280 1360 1544 1888 1024 1024 1027 1072
Interestingly, nvidia based and vesa based xorg.conf files are almost identical, particularly monitor settings are the same but result in different refresh rates. Any help with this is greatly appriceated.
Following are the xorg.conf files:

This must be a bug in readings, my refresh rates go from 50 to 54 Hz while the screen is clearly doing the old 85Hz(I'll notice anything below 75Hz).
That being said it is not impossible that by changing xorg.conf your monitor is now doing a low refresh rate.
Don't use modelines, that is old school, and they do more harm than good usually these days.
Also you are saying you have a LCD monitor, so low refresh rates should really not matter in eyes strain.

I have noticed that on my dual-head GeForce4-mx440 card running TwinView, KControl thinks my refresh rate is 50hz.
Fortunately, one of my monitors has a button which displays the current settings and it is indeed getting a 75hz refresh.
In addition, the Nvidia utility program indicates that both monitors are set to 75hz refresh.
That's in Mepis 6.04 / 6.5. using the 9631 Nvidia driver. In Mepis 3.4-3 (using the 8776 driver) Kcontrol sees the refresh correctly.
I suspect you're actually getting a 75hz refresh when KControl says 50hz.
I thought that newer Samsung monitors, when you pressed the Auto Adjust key briefly showed the resolution & refresh they were being fed. Can you check that way?
Yep...

I can see settings on my monitor, too (thanks for reminding me).
Same thing here. The refresh rate and choices shown by KDE is where the problem is. The actual refresh rate is different.
I thought my monitor looked and worked fine with the newer Nvidia drivers in the 6.5 RCs (I'm using a CRT and have an Nvidia FX5200).
If I right click on the desktop and go to "Configure Desktop>Display", it's showing a refresh rate of 50hz with choices for 50, 52, 53, 54, 55hz.
Yet, if I press a button on my monitor with the 50hz option in KDE, it's showing v:85.4hz
So, it's a bug with the way KDE is interpreting the choices instead of an actual refresh rate problem.

I've read about that on the Internet. However, for whatever the reason, my eyes get so tired with my home monitor. I dimmed the brightness of the LCD and it's helped though.
It may may be due to the long hours I've been spending at PCs at work lately and also when I see the 53 Hz as refresh rate, I may be psychologically influenced.
Thanks for the reply

Actual? refresh rate is 60 Hz

I used the monitor buttons and discovered that the refresh rate is 60 Hz.
I'm quite confused, I'll wait for the stable version and do a clean install and see what happens

60Hz is normal for a LCD.
If you are more comf with a higher rate and the instructions don't give a preferred refresh rate you could use this:
Section "Monitor"
Identifier "Monitor0"
VendorName "Samsung"
ModelName "unknown"
Option "DPMS" "true"
HorizSync 30-81 #check this !
VertRefresh 56-75
# Option "UseEdidFreqs" "false"
EndSection
You might or might not need "Option ' UseEdidFreqs" "false" '.

I posted the issue on local LUG and got this reply, quite interesting:
We (Mandriva) have recently discovered via a user bug report that the
NVIDIA driver does not report the refresh rate correctly to X.org,
consequently xrandr and higher-level tools like krandrtray all show an
incorrect refresh rate (i.e. not the one that's actually being used).
You should always trust the information provided by your monitor's OSD,
that will always be the most reliable. If it says it's getting a 60Hz
signal, then it is.
Most LCDs want a 60Hz signal. There are a few which want a 75Hz signal.
The 'native' refresh rate of your monitor will be listed in the manual.
You should always drive it at this rate, so if it says 60Hz in the
manual, then relax; everything is correct. An LCD that wants a 60Hz
signal will often *accept* a 75Hz signal, but you shouldn't do this - it
won't make anything smoother and will actually usually lead to odd
visual artifacts as the monitor is forced to adjust the signal. As a
previous poster said, LCDs do not flicker the way CRTs do, and you do
not need a high refresh rate with them to avoid flicker and eyestrain.
The Mandriva bug report, for anyone interested, is here:

I've done a fresh installation of the final 6.5 and my monitor's built-in menu shows 75 Hz. I will not edit the xorg.conf although display settings offer only 50 and 51 Hz.
Thank you all for offering help.

When I look at the refresh rate using the newer Nvidia driver, it shows something like 50hz for my monitor, too. I've never seen that kind of thing before, other than with the latest drivers in the newer RCs.
I tried several things to try and get it to display the same refresh rate as the older Nvidia drivers (specifying vsync at bootup using the opt in nvidia driver and more). But, it just doesn't seem to give me the choices I've seen with other Nvidia drivers in the past, no matter what I try.
But, I don't see any difference in monitor quality. So, I was wondering if it was just some kind of "fluke" with the way the refresh rate choices are being displayed (i.e., 50hz is really 70hz). lol
I'll keep an eye on this thread for any solutions.
