I purchased few different video cards for my Dell Optiplex GX 620 and they all have the same problem - when i connect to other outputs, the picture is good, but from HDMI output the picture is fuzzy. I went over all these forums but still nothing helps.

Probably the cable. What kind do you have? (it does matter to some extent)

Have you tried HDMI input on a different monitor?

Yes, you should try that. It will show if it is a problem with your cable (my suspicion) or the monitor. Hope you can return it if the monitor is broken!

+1 to Wiggler.

Try it on a monitor who's HDMI connection is known to work perfectly fine. If it's still perfectly fine, then you have a faulty monitor.

If it still doesn't work fine, i suspect the cable (despite you saying it's the best you can get). Either that or you have had one bitch of an unlucky streak with faulty GPU's!

I should mention that not all cables are created equal. What resolution are you attempting? Not all cables can support 1080p (correct me if I'm wrong).

You are right in saying not all cables are created equal, some are poor quality, others are incredibly high quality.

95% within the 1 - 3m length range will support full 1080p, the poor quality ones may not be able to support the data throughput required for 1080p and thus relegate to 1080i.

Past 5m or so, the quality of the cable really comes into play as signal degradation becomes a larger factor.
