But it appears there is something untold here. That is, the PC and monitor are incompatible in some way. Back in VGA days once in a while you would run into a card or display issue and try all the settings and fail. At that point you change the card or the display.
You are dealing with a very old issue. I'll share my findings over the decades.
Hi! I have problem with monitor, because it doesn't want to put picture at right place. Actually, on AUTO Adjustment nothing was changed and i have one black line on top, and i don't see start menu (but, it was there, under monitor screen).
I have recently started to use my computer on TV, but to do that i can only use VGA cable as an option. So, because i have only one VGA input on computer, i must change cable every time when i want to use monitor/TV. After a few times, when i changed a cable back to monitor, picture wasn't set correctly and i pressed AUTO Adjustment and then monitor made a black line on top, and for the same dimension lost at the bottom. If i change picture to TV again, there is all good.
I try everything around graphic card to solve this problem, but nothing changes. V-Position on monitor settings sets to 255 and it is locked and I can't move it. H-Position works good.
