Has anyone seen, came across this before? Every now and then this black box appears and goes up and down with the courser. Only way to stop it is a reboot. This is a monitor plugged into a laptop via HDMI. Makes no difference if both screens are on or using one, nor disconnecting the monitor and just use the laptop one. Reason the huge courser is the owner is partly sighted so needs the larger screen. Not sure if this is a nasty bug or not. He says there is no pattering to when it starts. I was thinking its a nasty attached to his courser (Edge) so left him with Brave for the time being.

I take it that when the problem occurs, the black (lower) part of the screen image goes up and down following the movement of the cursor? I've never seen that before, but would suggest buying a new, decent quality HDMI lead to see if that is causing the weird sh1t...

Yes but only up and down. It is a cheap Tesco HDMI but been fine for the past three month but worth a try.

windows + oddity = normal procedure

Has your monitor got a PBP (or PIP) mode? This is where it displays 2 inputs side by side (or on top of each other). Check if you have that mode and you haven't accidentally enabled it.

This will be a setting in the monitor menu, not in windows.

I think the cursor is causing it. I find accessibility options can start and do odd things when I don't want them to, is the cursor setting a windows one or something downloaded?
