Ghosting Effect??

[Gum]

Got a setup of G400 DH 32Mb and Samsung 700IFT, using PD5.52

Got hold of BNC cables and tried them on my Samsung 700IFT. For the initial month, everything went very well and the better quality graphics the BNC produced was very impressive.

Recently, I seem to notice some "ghosting effect" on my screen. No matter what PD version I try, or screen resolution and refresh rate will not make the effect go away. Only when I got frustrated and tried changing back to 15-pin D-SUB then everything was back to normal.

What went wrong? Faulty BNC cables? Thanx.

Hi,
I had exactly the same problem on my Iiyama Vision Master Pro. 410.
Had my monitor replaced by Iiyama, all ghosting effects have now gone.
So in my case it was definately a monitor issue.

Thanx for reply.

I think mine should not be a minitor related problem since the 15-pon D-SUB works properly.

I think i might have bought a faulty BNC cable...Any other comments guys?

It might very well be either the cable or the monitor. You are going through different connections (on the monitor) and cables. It is certainly a connection problem and trial and error is the only way I can think of to sort it out.

Try the cables on another monitor. If the work correctly under the same conditions as on your monitor, try them on your's again. If they revert to bad behavior, then it is the monitor. If they perform correctly then it was the cables or the connections on the monitor (then leave it alone).

If they don't work on the other monitor either, then it's the cables

You may try moving the cables around while the monitor is showing the ghosting signals. If it's the cable, then it may vary in quality when you twist or wiggle the cables.

Try checking the connections both at your computer and on your monitor. Make sure nothing is loose or wiggles too much.

Also make sure there isn't anything producing too much EMI nearby. Perhaps your cables aren't shielded adequately?

Or your monitor may be faulty?....
