Today I had a task to change an old CRT Monitor to LCD BENQ Model FP61E on a computer running Microsoft Windows XP SP3.
Changing phyiscally the monitors and restarting the computer to load with the new BENQ monitor ended up with the LCD Monitor showing a blank screen with error:
Out of Range
making the computer completely unusable.
Thanksfully in Windows Safe Mode the monitor was able to display the screen properly, so I had an option to operate somehow on the pc
My guess was that the Out of Range monitor problems were caused by an incorrect (monitor unsupported resolution).
Therefore what I tried as a fix to make it work was:
1. Enter Windows Safe Mode and change (lower the resolution) to 640×480, and restart the PC.
Unfortunately using this classical way to fix such issues failed… so I thought of some options.
2. Disable the video card NVIDIA Riva TNT2 Model 64 driver and check if this will make any difference.
I come up with the idea the Out of Range LCD issues might be caused by the Video card driver cause I've noticed in safe mode a standard VESA like VGA Driver shipped with Windows worked just fine.
To Disable the currently loaded NVIDIA Riva TNT2 Model 64/ Model 64Pro I used:
System -> Device Manager -> Hardware (Tab) -> Display Adapters
Clicking on Display Adapters the NVIDIA Riva TNT2 Model 64 appears using the option menu on it one can choose to disable the driver.
Further on restart Windows, to test if the XP will load properly with disabled NVidia video drivers.
Onwards it was clear the whole Out of Range issues were caused by some kind of conflict between the LCD BENQ FP61E Monitor and the NVIDIA Riva TNT2 Model 64
Often latest video drivers solves hardware incompitability issues and fix many bugs, upgrading the driver to latest is always a good idea.
3. Therefore I Upgraded the NVIDIA Riva TNT2 64 driver (using Safe Mode) to the latest available from Nvidia's official site.
Weirdly Upgrading NVidia Riva TNT2 drivers to the latest did not fix the Out of Range blank screen error.
After a bit of thinking on what to do to make the Monitor work fine with the Nvidia driver, I thought of completely uninstalling the Nvidia drivers and installing them again might be a fix.
In my previous experience with Windows at many occasions, uninstalling a driver failing to properly work and installing it again with a working version was a good fix.
4. Uninstall the NVIDIA Riva TNT2 Model and Install the latest driver.
Uninstalling and Installing the Video driver had to be done in Windows Safe Mode again, in normal mode the windows was not displaying anything.
After The driver installation program completes the installation it requires a restart. After the restart the Video driver gets loaded fine and Windows loaded up in Normal mode as usual 😉
