Resolution Problem

Try holding down "Shift" key, then select "Restart" This will bring you to "Choose an Option" window.

Trying to think about that suggestion, but if nothing on screen seeing how this option is possible, why only other suggestion was Shift+F8 tapping F8 while holding shift on boot up.

example here in first 2 posts of failing to get to safe mode and Brinks suggestion, make a disc if all else fails from another PC.

Once at the "Choose an Option" window, select "Troubleshoot"

Then select "Advanced Options" in the next window.

At the "Advanced Options" window, select "Startup Settings"

At the "Startup Settings" window, select either "Enable Low-Resolution Mode" or "Safe Mode"

Press the number which corresponds with your selection. Use number keys or F1-F9.

Make your changes.

This only works if I can actually see the desktop, at present I cannot see the desktop because I have selected a resolution that is not supported by my monitor so nothing is being displayed.

Users said "KBM" switch, should it be "KVM" switch ?
Please connect system directly and test, don't connect via KVM switch first to see if you still can see the desktop or any video.
If video is correctly showed, then it can be sure that the problem is the KVM switch which did not pass correct EDID information or
did not have EDID emulator built-in on the KVM switch.

Thanks for all your help guys, the problem is now resolved as I treated myself to a higher resolution 4K HDTV so was able to adjust the resolution once the new screen was connected.

It should be noted though that there was no way for me to adjust the resolution on the old monitor even when connected directly avoiding the KVM switch, as I had exceeded the maximum resolution of the monitor so unable to switch it back.
