Thomson STBDH1685P was working perfectly. I tried to change the resolution of the screen and now it wont work. Message reads Mode Not Supported. Cannot get Menu options. How do I factory reset.

Start pc in safe mode and try to change resolution.
Then update the graphics driver.

Hello,
This generally means you have the display resolution set higher then the monitor can support. To fix this press F8 after you turn the computer on. You may have to press it a couple times before the windows loading screen. A black menu will come up. Select safe mode. Your PC will load into safe mode with minimal drivers and settings. Go to the control panel and select display. Change your screen resolution to something lower then the setting is is at right now. If your screen is 19" or smaller try a setting of 1024x768 for starters. If its 20" or higher try 1280x1024 for starters.

Seems that you have set the resolution on your graphics card to a setting higher than the maximum resolution supported by your monitor.
Try to boot into Safe Mode & lower the resolution of your graphics card. If not possible, go to Device Manager & remove the graphics card from it, then reboot your computer. This will reset the resolution.
You can then re-install your graphics card drivers & get it to work properly.

The resolution selected in normal mode is not supported by your monitor.
Instead of booting into safe mode, boot into VGA mode - this should allow you to change the resolution - change it to one that works and then you should be able to use normal mode.
Hope this helps, Sherwin

This means that the windows setting you have set can not display on your current monitor. There are two ways to fix this, one is to boot the computer in safe mode by pressing f8 after the POST screen and change the resolution and the other is to plug the computer into a different monitor to see if supports that resolution and then change the resolution in windows to a lower setting.

In case you don't know how to change the resolution in windows, follow below.

Right click on the desktop
Properties
Settings at the top
Move the slider to 1024x768
Click ok

Try rebooting. If that still doesn't work, try another resolution.

Sounds to me like the input has gone out of the boundaries the monitor supports. IE the refresh rate is too high frequency (normally 60 to 72 Hertz for LCD's) or the screen resolution has been set too high.

Go into safe mode and set it back to 1024 X 768 at a frequency of 60 Hz, once back into windows proper you can try higher resolutions and change your refresh, if the screen goes black or displays a message "Out of Bounds" or similar it should revert after 15 seconds if left alone.

Have fun

2 options:

1) Try changing your screen resolution to say 640x480 or 800x600 ..

2) Try it in safe mode also ..

Since this was a new out of the box computer, Safe Mode was not allowed. In order to change monitor settings (resolution), I had to use another monitor, in this case a newer CRT. With the CRT, the computer booted up, no problem. Once booted, I turned down the monitor resolution and saved. Now when the Princeton LCD was plugged in and the computer restarted, everything works fine. Now the resolution could be set to limits of the monitor.

You have set a resolution that is too high or incompatible with your monitor. I assume you are using Windows. Turn the computer on and immediately keep pressing F8 on the keyboard until the 'Windows Advanced Options Menu' appears. Use the Up and Down keys to select 'Enable VGA Mode' Press enter and your screen will work again when windows starts. Now go to the display properties and click 'Advanced' then click the 'Monitor' tab and tick 'Hide modes that this monitor cannot display' OK everthing and now you should be able to adjust the resolution without getting a blank screen again! Good luck and come back to comment soon. Regards
