Need help with monitor issue

Amleto · 31 Oct 2017 at 21:46

Hi,
wife has a problem with monitor output stopping.

The only constant seems to be this happens on 'display 1' - she has dual screen setup.

We initially swapped cables (dvi) and gfx card - still had the same problem so RMA'd the monitor. The replacement did exactly the same.

I've since swapped out the motherboard (intel i3) (one I had lying around with its own set of RAM and amd phenom II cpu).

Probably accidentally swapped monitor connections around... the exact same issue is now happening on the other monitor.

So with completely different monitor, dvi cable, ram, motherboard, cpu, gfx card we have this recurring monitor display issue.

I have tried loading in safemode, deleting display adapter driver and reinstalling latest non-beta from ati - no luck.

OS: win10
psu: 620w antec.
gfx cards: hd4770 + hf4650

Please help!

It could be a power supply problem, if it's dying it may not be able to send enough signal to the monitor for it to pick up.

How long are the cables? Are they thin or thick?

They are T H I C C. Cables already ruled out.

That sounds very unlikely since surely the actual gfx card would fall over before the output signal was lost.

It is unlikely but it even more unlikely that you are having the same issue after changing all of that, there's not much else it could be short of reinstalling Windows but I am assuming you have already done that.

Don't be so hasty. Do they run over or near anything that could induce current and thus affect the display?

Welcome to everyone on this forum, actually monitor is old technology not used now days. I think may be a cable problem or any other issue.

Fresh OS installs?

No, nothing. Also there has been no change and the system had no issue for 1-2 years.

Haven't reinstalled o/s, but, save for PSU, it's the only option left that I can see.
