Welcome to the world of Voodoo 1! Use a Voodoo 2 instead or live with it unfortunately 🙁

Voodoo2 also has moving diagonal lines also. They're VERY noticable on LCD... and no they're not something i'll do in the shader 🤣

The V2 isn't perfect but I hardly notice it by comparison. I have a sentimental attachment for this V1 - it's the original one I bought all those years ago. I keep testing it out hoping it will work as well as I remember it working!

I reduced the noise on my Voodoo 1 setup by running a very short cable and making sure other cables were well out of the way. Switching PCI slots and being careful of internal cabling helped too. Some 2D cards seem to have a better quality output in the first place.

Surprisingly, switching to a different AT PSU helped in my case - the older PSU must have been a little 'noisy'. Still isn't perfect though. A CRT masks a variety of sins.

i have same problems with my pass through cable on voodoo1 to voodoo3

i use a lcd samsung syncmaster 913n and i see always strange oblique lines. often the lines become wider and sometimes become smaller.
I see the lines even while i play the games and it's annoying...

The cable is long 1,5 m and is not shielded and the monitor is set to adapter - optimal refresh in windows

help me!

I can build me a m/f shorter cable but shielded? how many cm long was that of 3dfx?

or i must buy a old monitor CRT?

i have buy this:

the cable does not have the cylindrical blocks

had the same diagonal lines problem, out of the 3 voodoo2 cards I have one is better at this and you need to really pay attention to notice them... so I just use this as a master card... so the quality between v2 cards varies as well...

The by-pass cable is short - about 12".

I have 2 and neither of them are or objectionable. It's just the V1, it displays the crazy interference patters. These patterns happen on the desktop and 2D apps too, but less so. For now I'll probably keep the V1 installed, but plug directly into the 2D card unless I need the 3dfx..

my 2d card is voodoo3 3000 and i need this card for play some games.

i use also v1 (diamond) for old games working only on this card.

i want know if this oblique lines of interference are problems of my monitor because is a lcd, the cable because is long 1,5 m and is not unshielded or my v3 card

I would like to try with a new good short cable with this crt that i want buy:

@dario: If you get the interference only when you have the V1 hooked up, then that's the problem I've been having - and others as well from the sound of it. If you are also getting the same degree of interference from the V3 then I don't have an answer, except I think the normal VGA cable you plug into the monitor is usually shielded, and has always worked well for me..

Figured I would drop my two cents since I have dealt with this issue extensively. Back in '97 I had a Diamond Monster 3D that used to do the exact same thing as the OP's card - display a noisy, slightly distorted image. Fast forward 17 years and lo-and-behold, a Canopus Pure3D I snag off eBay does the exact same thing. Noisy image output, most noticeable as a "squiggly" image as described in the OP. It doesn't matter if it's on a CRT or LCD, I have seen this issue on both display technologies - it's a matter of how tolerant the monitor's electronics are to a noisy signal.

The only solution is to either A. buy a new card and hope it displays a crisp image B. find a CRT monitor that may display the exact same issue or C. deal with it.

Considering I can buy a Voodoo 5 AGP for the same price as the Canopus board, I think I'll try C. since nobody in Michigan seems to want or have CRTs anymore

It's sort of a relief to hear that this is an endemic problem, not just mine. My solution is "deal with it". The V1 is parked in a P-233/S3 era rig as a living monument to the first age a 3D. But I also have a P3-966/V2-SLI and a V5 system to fall back on for real Glide gaming.

I did manage to improve image quality by hand selecting the LCD refresh rate rather than relying on 'default' or 'optimum', and installing Diamond's 'InControl Tools' for the 2D card [3D-2000 Turbo] to adjust screen resolution and color-depth seems to have stabilized the image a bit too.

So right now IQ is not too too distracting, and worth keeping as a testament to the early days..

I live in Michigan as well. Most goodwills in my area have crts. Also try the mission stores.

AGP card into DVI and Voodoo into VGA. Switch between DVI and VGA when needed 😀

i have solved with a 19" LG CRT 99t with BNC input for voodoo3 and normal vga for voodoo1 in my monitor 😀

Hi guys,
sorry for resurrecting an old thread, but I just wanted to contribute this:
I recently bought a Voodoo1 card (generic 3dfx) and hooked it up to my 24 inch LG LCD panel (that still has a DSUB port). After playing with some 3dfx demos, I immediately noticed that there were dark vertical streaks running along the monitor.
What "fixed" it for me (or at least got rid of the issue to the extent that it's no longer noticeable) was to adjust the monitor's "Clock" setting (through its "Display" menu) from the default 50 to 51. The "Pulse" setting also seems to have an effect on those vertical lines.

Hope this helps someone.

Cool. Next time I fiddle with the V1 rig I take a look at this setting...
