Windows 7: CRT Frequency issues - Getting annoyed

CRT Frequency issues - Getting annoyed

In Windows XP I used a program called Reforce to force my refresh rates for specific resolutions I would use while gaming. That meant 100hz for 1024 and lower resolutions. Now in Windows 7 I've tried every possible way of solving this but I'm seriously out of ideas now, also I've spent several hours on these forums + other forums trying to find a solution. The problem is, I can't force the frequency for the resolutions with any program, nor from Nvidia control panel. You can see my other posts on similar threads.

Just found another bug, It doesn't allow me to change resolutions either properly, If I go to normal Screen Resolution and change it, it somehow only scales it, my monitor still says 1280x1024 if I put it to 1024x768 for example. That could have something to do with the refresh rates.

My monitor is Samsung SAMTRON 98 pdf 19" CRT

Samsung Samtron 98PDF 19 inch CRT Monitor - Product details and features - DealTime

Windows 7 atm tells me my monitors max resolution is 1280x1024 at 85hz.

Things tried so far:

Reforce (in administrator + compatibility)
Refreshlock (in administrator + compatibility)
NVIDIA control panel custom resolutions
Powerstrip (in administrator + compatibility)
Made my own driver for the monitor with powerstrip
Rivatuner (in administrator + compatibility)

Probably something more aswell I can't remember right now. None of the above has proven to be any successfull. The only idea I have is to plug this monitor to a Windows XP system, copy the driver it automatically uses for this monitor in XP since it worked before (with reforce) and try it out in Windows 7.

Please, do help me. I'm seriously getting annoyed by this thing since everything else in Windows 7 have worked fantastic and I really love it, I just can't do any gaming without getting 100hz to FPS games.

Also I'm not sure if this thread should be in driver category.

Windows 7 64 bits
Same problem - Locked refresh rate

Hello all. I have the same problem...

I bought new hardware (mobo,cpu,ram,Ssd,Case) and instaled windows 7 64 bits, because now I have 4gb of Ram. I also have an ATI 5850, a big Samsung Syncmaster 1100MB CRT, connected trough a DVI - VGA Adapter. When I was with Windows 7 32bits the 10.2 Catalyst worked fine, although when I tried to install 10.3 Driver the resolution locked at 1024x800. So I rolled back to 10.2 and everything was fine, I decided to wait for a new driver to update.
But now I have windows 7 64 bits and tried with 10.3 and there are some resolutions available, but with a maximum refresh rate of 60hz! I used Drive Sweeper and tried the 10.2, the 10.4 Preview, tried changing windows Registry, tried ATI Tray Tools, and NOTHING WORKS! My eyes are hurting and so is my head with all this. Are CRT banned from ATI Drivers from now on? Should I install 32bits or change from ATI to a NVIDIA Card?
Can someone please help us please?

Thanks in advance.

Welcome to Seven Forums: Their is information on EDID refresh rates locked only on the 5770. Try searching google for EDID refresh rates locked. I think their is a program avalible to help unlock the refresh rates on CRT's. And while researching you have been given plenty of good information to look into. Fabe

Windows 7 64 bits

I got it! The tutorial in that forum worked, after days os struggling. Thank you all!

  1. Download and extract it to a working folder.
  2. Run it and click the registry toolbar button.
  3. Click the pencil toolbar button for edit mode.
  4. Change the EDID settings to reflect you display's true capabilities
  5. Pay special attention to the Standard Timings tab.
  6. Detailed Timing blocks 2-4 provide some very interested additional options.
  7. Save the EDID to a .DAT file in the working folder.
  8. Download moninfo.exe and install it.
  9. Open the saved .DAT with MonInfo and make sure it doesn't complain about it
  10. If it does post here for help
  11. If MonInfo reads in an displays the settings the way you configured them in Phoenix then...
  12. Select Create INF... from the file menu and save it to the working folder.
  13. Feel free to edit the strings in the INF to your liking.
  14. Open Start, type devmgmt.msc and press Enter.
  15. Select the monitor you want to change, right click and select Update Driver Software
  16. Use the tried and true "Have Disk" method to select the INF and install it.
  17. Reboot and enjoy your new resolution!
