I've got an old monitor and I've updated it to Windows 10 like 3 weeks ago and since then in the middle of my screen there is a blue box which keeps saying "MODE NOT SUPPORTED" H: 75.2KHZ V: 60.2HZ. Its refresh rate is set to 60Hz. When I had windows 7 it only showed this message when I went onto some game (cant remember it's name) but I soon fixed that problem. All the buttons on the front of the monitor do not affect the message or the monitor. Only the power button for it works. What could be the reason and can I fix this problem?
