No, from whether it does what it's supposed to do or not. Price has no relationship with whether or not something works, and too many companies really rip you off for cables.

If you replace a cable which is giving you sparkling pixels with another one, and with the new one the sparkling pixels go away, then the one you replaced was bad, and the new one is good.

On the other hand, if you have replace a cable where you get sparkling pixels, and with a new cable you still get sparkling pixels, the problem is probably elsewhere.

I tried another cable (dual link) which still shows the problem...
Can it be a monitor problem?

I'm not sure, but if possible that would be unusual. Sparkling pixel problems that I've seen have always been video card or cable.

Trevor

I found that the new cable which I just changed works sometimes but not always. So, changing cable did work~

That's odd. Do you have some strong source of radio frequency junk nearby? Perhaps a microwave oven, or something with a large motor?

Trevor

I have 2 studio monitors (speakers) Alesis PROLINEAR 820

Those Alesis monitors are shielded for use with CRTs, and shouldn't be a source of radio frequency junk unless they're completely broken.

Trevor

I think so... Those dots really bothered me... should I try different cable?

Maybe if you can find a cable with extra shielding, or that uses a braided shield rather than a foil shield, you should try that. It's still very odd that you get the problem sometimes but not always with the new cable, it makes me think that there's another factor involved as well.

Trevor

same problem here:

I'm sure a lot of you were hoping for a fix with this thread bump but alas, I don't have that for you.

I will say this though. I went and bought a 30" Apple Monitor and I am no longer having any problems.

So there you go, if you want the problem to go away just buy a new one. Certainly not a fix, but hey, it works.

I think we need to consider this thread DEAD. This is not something that will be fixed.

Try using a different PCI-ex slot. This worked for me I used the second slot from the bottom.
