Windows 10 Problem

[Roy Dennis]

It sounds like you may need to update graphics driver.

You don't state your computer make or model but start of by Right click on the Start button in widows 10 that should bring up a list, Click Device manager, then select display adapters, you may have more than one, right click on one and see if update driver appears or properties, if you select properties it should bring up another dialog, select driver then on the next view choose update driver.
Let it search the web for driver.

If more than one type of graphic appears repeat on the other one as well.

Should it not find an update go to your computer manufacturers web site and see if they have any updated drivers . Failing that go to your graphics manufactures site direct and search for new driver there.

See how you get on after trying the above.
