7800 GTX and CRT monitor problems

[zagadka]

I recently got a new built system with a PCI 7800 GTX. Everything works fine except when I plug in my CRT Compaq P1210 monitor using the adapter provided. On my 19" TFT the picture is crisp and clean but on the CRT there is a slighy shadow on everything. The same CRT functions perfectly on my old ATI 800XL PE at all resolutions. I have tried playing with the settings but cannot find a way of adjusting it.

When I go onto 'advanced timing' setting and select 'interlaced mode' the shadows disappear albeit the quality seems to be reduced and the display looks grainy and with subtle lines.

I am not an expect and would appreciate some pointers about how to set up the card as though a process of elimination I am certain that I can adjust the setting on the graphic card to make the display smoother and clearer.

Thanks

C'mon guys... someone must have had similar problems with a CRT monitor?

I've found the image quality slightly decreases on my CRT if I have to use a DVI->VGA adaptor. If you're using one of them make sure it's screwed down really tight, and if possible look for a high quality one - I don't know if you can get gold plated ones, but I would recommend doing so if you could.

Otherwise try a range of refresh rates and see if that helps.

Thanks I will do.

Would the adaptor account for the shadow on screen?

[zagadka]

Well... the 'experts' at Maplin inform me there is no such adapter.

The first things I tried were the latest drivers fot the card, monitor and fiddled around with every combination of resolutions and refresh rates possible.

As the monitor I am using is pretty decent (P1210) and it worked fine on the old PC with an ATI 800 PE, surely it would work on a 7800 GTX?

My screen used to shimmer, all the text, with my 7800GTX and CRT. A high quality cable did the job, but i couldn't install monitor driver after that.

Ive got a 3mDVI-VGA cable, high quality belkin, i could sell you, if you needed it.

Without trying to be pedantic :-) ; what do you mean by 'shimmer'? My picture is steady but there is a shadowy blur around text? Smokey, did you get gold plated connections? Anyway - how much?
