I have an LG monitor attached via an HDMI to VGA adapter. This has always worked fine either on "Duplicate" or "Extend" settings from the laptop.

I have just put a new hdd in the laptop and done a fresh install of windows, updated all the drivers etc. Version 10.0.18363 Build 18363


Now my monitor is not found when I try to detect it in Display Settings. I cannot duplicate display but I can extend, or display on second screen only so it is obviously being seen okay by windows.

The biggest problem is that if I try to run a game (Doom) on the second display it changes display to 640 x 480 and (obviously) looks terrible. It ran fine on second monitor before.

Monitor is running off the Intel graphics chip and the drivers are the latest.

Any ideas?
