This has happened twice before. For no reason at all that I can fathom I log on and find that I have broad black margins at the side of the screen.
On those other occasions I was receiving helpful advice while messing about with the full screen icon and, before I could follow any of the advice, it returned to normal.
So I never did find out what caused it or what cured it.
It’s happened again, but messing about, including rebooting, has not helped. I followed some instructions which brought me to a Resolution box and was advised to choose 1920-1080 from the drop down menu.
The box says I have 1024-768, but it is greyed out so I can’t change it.
Any suggestions please? A laptop screen is small enough as it is without making it even smaller.
David, without knowing the operating system, and version number, we’re likely to make a lot of assumptions that won’t necessarily get us any further, or make suggestions that won’t be of any use to you.
Thanks again for all the replies, I think the best thing to do is bring the laptop here next to the PC (notPV ) so I can read and try advice seperately.
But I have some things to do first, mainly dog related.
David, yes, that is useful information. We now know which graphics chip is onboard, and the resolution at which it should be displaying. For some reason, the desktop resolution has been downscaled from the output resolution.
I would hasard a guess at a Windows/driver update being the cause.
But we do now - you have the 1280x800 panel (so no point trying to set higher than that) and Nvidia graphics, and the Nvidia is active, not the Intel built-in graphics adapter.
You might be able to change resolution in the Nvidia settings (right click on the desktop background and look for “Nvidia settings”.
Also - laptops with dual display adapters (in your case the Nvidia and also the Intel built-in graphics) usually have a way to switch between them using the Nvidia for “performance” and Intel for “low power/longer battery life”.
Worth checking how to switch between them - it could just be that you have accidentally switched from the Intel graphics to the Nvidia GPU.
