While trying to help a friend I googled his problem and the suggestion to fix it was to enter ALT+CTRL+RIGHT ARROW KEY. As soon as i did that a blue box popped up on my monitor with message input not supported. I am running Windows 10. I have literrally spent hours searchiing for a solution and have tried multiple things all to no avail.I connected a flat screen tv to the computer with hdmi cable and it is working fine.
How about some information that will help identify your friend's problem?
Complete processor model number?
System/motherboard model number?
We assume WIndows 10?
We assume some sort of graphics issue?
What is the problem and what has been done/tried?
Any other hardware model numbers?
Be specific! We cannot read minds.
