External display

Hi John,
We are sorry that the external display is not working in your computer. To confirm this is not a hardware issue, we request you to check the cable connectors and VGA connector. Try to connect another monitor and check if AVG is working fine. We suspect that it might be a hardware issue. Please perform the above steps and revert to us so that we can conclude if this is an AVG issue. Thank you for understanding.

The external display is not working I think it follows running the tune up routine when I disabled a number of programes to speed things up
How do I reset the PC so that external scree/display works?

When I switch to a benq external monitor GL2250 itworks fine but the other benq monitor GL2450 doesnt and it has happened the day after I fully installed the AVG ultimate programme which I had just received as a present so I reckon one of the programes prompted by AVG to disable has prompted the monitor failure
If I uninstall AVG completely will that remove all those program settings etc that was selected to be disabled - that way I would know for sure whether its hardware or AVG software. I can always reinstall AVG later and be more careful next time as to what I disable.
