I recently built a new PC, and also purchased a 27" 1080p monitor to go along with it. The monitor came with an HDMI cable, so I decided to hook it up. Much to my surprise, the picture was rather blurry, particulary words on the screen. Reducing the resolution from 1920 x 1080 to 1680 x 1050 cleared things up, which I found odd. After some googling on the issue, I brought my old DVI-to-DVI cable out and hooked it up, and now everything is crystal-clear at 1920 x 1080.

Has anyone else experienced this? Are HDMI cables strictly for high-definition video playback, and suck for other things?

What's the dot pitch on the monitor? Do LCDs still have dot pitch?

HDMI cables are just DVI with integrated audio and a sexy plug. Maybe your card has problems outputting the source or your drivers freaked out when they detected HDMI as the source (Nvidia drivers often declare I'm using an RGB cable, for instance, and then you can't adjust scaling settings).

The manual says the "pixel pitch" is 0.3114mm x 0.3114mm.

I'm just going to chalk it up to my drivers freaking out, even though they are the latest ones from ATI's website. Everything looks fine using the DVI cable, so no worries really.

I had the same issue with my 23" Samsung LCD TV, which I also use as my desktop PC's monitor. It seems that the problem is that if you feed it a 1920x1080 @ 60Hz signal, it'll misinterpret it as being a 1080i signal (1080p is usually displayed at 24, 25 or 30Hz), try to reformat the signal for the panel's native resolution, and in doing so utterly fuck up the picture. Near as I can tell, unfortunately, there's no way of preventing it from doing this, but it's not an ATi issue since the same thing happened with my old Radeon 5670 and my current GeForce GTX 470.

If that's the problem, just look up in your manual how to let the TV know its getting a DVI signal on the HDMI. On Samsungs, this is done by using HDMI1 (the one next to the DVI plug) and editing the name of HDMI1 to 'PC' or 'PC/DVI'. The manual actually tells you to do this, but I thought it just told it to use the 3.5mm jack for sound. You should do this anyway to reduce display lag.
