Refresh Rate Incompatibility

May 16, 2009 at 02:59:02
Specs: Windows Vista, Athlon 3000/2GB
I just bought a new Samsung SyncMaster
2233SW Monitor. It's resolution is 1920x1080.
During boot-up, I get a monitor popup error in
the middle of the screen stating "Not Optimum
Mode - Recommended Mode: 1920x1080
60Hz". When it actually gets into Windows
and the display settings change, the window
goes away.

Here is my problem:

When I am in the BIOS or in Safe Mode, I get
this popup and after 60 seconds, the display
shuts down. The only way I can get it back is
to turn the monitor off and then back on again.

Here is what I have found out:

The default display during boot-up and in the
BIOS is 1280x1024 at 75 Hz. Apparently the
refresh rate is the issue. When in Windows, I
have changed the display settings to every
possible mode, and only get the popup when
set at 75 Hz. When in Safe Mode, I can
change the resolution, but all modes are set to
"default refresh", & it doesn't state what that
rate is. According to the monitor, it is 75Hz.

My question:

Is there any way to change the default refresh
rate of my ATI Radeon (X1600Pro) video card? Is there
any other way to change it in the BIOS or
when in Safe Mode? I would like to set it back
to 60 Hz. That way I should be able to get rid
of this issue in startup, the BIOS, and in Safe
Mode.

Thanks in advance!

Nathan

Try this. Right click on a blank space on the desktop and choose Properties. Click the settings tab and choose advanced. Next click the monitor tab and set your refresh rate form there.

I have tried that. That is how I have changed the display
settings to every possible mode, as I mentioned above. In
Safe Mode all when you try to change the refresh rate, the
only option is the "Hardware Default setting", which I found to
be set at 75 Hz. Are there any other methods to change the
"default setting"?

Maybe I should just return the monitor...

Is it even possible to change the display settings for your PC
for when it is booting or when in the BIOS?

Did you use the setup program on the cd that came with the monitor? It will usually walk you through the entire setup for the monitor. It uses a wizzard type setup program to optimize your display.

There is no way to change the screen resolution until you get into Windows. I have no idea where you're coming up with the BIOS display settings as being 1280x1024 at 75Hz?

You have to install the monitor driver as was suggested & possibly update your video drivers. Once you've done that, right click on the desktop, select Properties > Settings, then adjust the resolution. Click Advanced > Monitor tab & set the refresh rate to 60Hz. And make sure the box is checked next to "hide modes this monitor cannot display", then click APPLY.

There may be a setting on the monitor that allows you to choose whether to display the message or not. Check the manual. Most LCDs are supposed to operate anyway even when the resolution isn't set at what the monitor is rated at.

You've been given several possibilties - I don't see where you said you tried any of them.

I guess I need to clarify. The Monitor drivers and software have
been installed. I have spoken to Samsung and was told that
the monitor is only designed to display up to 60Hz and will
otherwise show the popup and then shut down after 60
seconds to avoid damage. (No way to get rid of this.) I know
what the display settings are when booting and in the BIOS
because there is an info option in the monitor menu that tells
me what signal it is receiving. (1280x1024 at 75Hz) I have
been in display settings and have changed the resolution and
refresh rate with no problems when in Windows. I have no
issues with the display when I am using the computer
normally. My problem is when I am booting up, in the BIOS,
or in Safe Mode, (i.e. before the video card drivers have
loaded.) It is then when the display defaults to 75 Hz. When
in Safe Mode, my monitor display will shut down after 60
seconds because it is at 75 Hz instead of 60 Hz. My question
is if there is any way to change the "default" refresh rate that
the video card displays before the drivers are loaded. When in
Safe Mode, you can change the resolution, but when you try
to change the refresh rate, it only allows you to select "default
hardware settings", (which, in my case happens to be 75 Hz.)
Hope this clarifies things and thanks for the help!

Well there's definitely no way to change the refresh rate in the BIOS. Safe mode uses a generic display driver with hardly any options because who really needs a lot of options in safe mode. There may be a way to get the default rate down to 60 Hz in Safe Mode by altering something in the registry, but I have no idea on how go to about this. I thought that 60 Hz was the default refresh rate in Safe Mode anyway, as well as in the BIOS, but I guess I'm wrong.

It sounds like 60 Hz is default for most video cards, but
apparently not for all of them. It should be getting more
common to have 60 Hz be default since most LCDs require
that or lower. But, it looks like what I am dealing with is a
"default refresh rate" that is set by the video card BIOS.

http://www.hardwaresecrets.com/arti...

It is not set by the MOBO BIOS, or by generic drivers in Safe
Mode. I have been researching a lot, but I am still at a loss.
Some video card companies offer BIOS updates, but it seems
that they are getting rare. There are apparently ways to hack
the video card BIOS and change the default settings, (the
display settings used by the MOBO before Windows starts
and loads the drivers,) but I am still not too sure how to do
that? Has anyone had experience with this?
