[QUOTE="igalan, post: 395208, member: 13477"] I have a question related to this thread, I don't want to hijack it but it's so related that may not make sense to start a new one. I built a new HTPC, my old one was aging and had some aches. I used a Sapphire 4670 with 512 MB GDDR4 video card for two reasons: HDMI port (with audio) and large quiet fan (it's impossible to hear it, the CPU fan is louder even at 1000 rpm). I've used ATI AVIVO in my older HTPC (Radeon HD3650) and they were excellent, so I stick to what works. The problem is that picture quality is bad, worse than what i had with VGA cable (at 1024x768). I've set the video card to output using standard 720p (on a 1080p TFT TV). The color range is correct, but I had to adjust the underscan option in CCC so all the screen fits in (with some lines being cut or else I had black lines at the left and also above). But still I get a shadow next to the pixels; web pages and other content with pixel width characters are difficult to read. The same effect if you use analog output (VGA) and don't have properly calibrated the signal on the TFT monitor. I've tried other resolutions like 1080p, but no luck. I thought that HDMI was like DVI, where the screen is sent pixel by pixel (instead of an analog signal that you have to render across lines of pixels and the screen has to figure out where to draw each pixel), but that doesn't seem to be true. I could use a DVI to VGA to get a much better picture quality, but I'd loose the ability to run 16:9 resolutions (my TV doesn't accept 16:9 resolutions on the VGA port -not very cleverly designed-) and a single cable for audio and picture. I'm no expert in this area, so if someone can enlighten me :) . [/QUOTE]
