Force native resolution to Non-PnP monitor in Windows



When using a computer with a non-PNP monitor, such as a CRT, Windows may not be able to automatically detect the correct native resolution of the monitor. This can lead to a blurry display or an image that is too large or small. To fix this issue, you must manually set the native resolution of the display in Windows.

To manually set the native resolution of a non-PNP monitor in Windows:

1. Right-click on the desktop and select “Screen Resolution” from the context menu.

2. Click “Advanced Settings”.

3. Select the “Monitor” tab.

4. Click the “Properties” button.

5. Select the “Driver” tab.

6. Click the “Update Driver” button.

7. Select the “Browse my computer for driver software” option.

8. Select “Let me pick from a list of device drivers on my computer”.

9. Select the “Have Disk” button.

10. Enter the path to the driver files (typically located in the “Drivers” or “Drivers\\Monitor” folder of the installation disc).

11. Select the driver for the monitor and click “OK”.

12. Select the “Monitor Settings” tab.

13. Select the desired native resolution from the drop-down list.

14. Click “OK”.

After completing these steps, the native resolution of the non-PNP monitor should be correctly set, and the display should no longer be blurry or too large or small. If the issue persists, it may be necessary to download the latest driver for the monitor from the manufacturer’s website.

It is also important to note that some monitors may require a special utility from the manufacturer to properly set the native resolution. If a monitor does not have a driver available, it may be necessary to contact the manufacturer to obtain the utility.

In conclusion, setting the native resolution of a non-PNP monitor in Windows can be a difficult task. To do so, users must manually update the driver for the monitor, and may also need to obtain a special utility from the manufacturer. However, once this is done, the display should no longer be blurry or too large or small.
