I just got a Samsung 40" 530 Series 1080p LCD HDTV and a Radeon HD 5450 but no matter what I do I just can't get it to look good with HDMI...I am not even close to knowing a lot about this but I have two other HTPCs I've built over the last couple of years but this is far the worst thing I've run in to...I have CCC set to 1080p 60Hz and even with it scaled to 0 in CCC and it set to dot to dot it doesn't show good HD video...I had to tinker with my other HTPCs to get the font on my desk top to look good and all that but I can't do it with this, or get 1080 video to look clear through HDMI..Have all the latest drivers for the 5450 and latest firmware for TV but VGA looks way better than anything I can get through HDMI...I would appreciate any help I can get...I've done all I know to do and now I'm kinda wondering if it can be done..Thanks to all who will take the time to help me...

A little more info to go along with what I've already posted; I've tried three different cables,along with an DVI to HDMI; I've tried different HDMI ports on the TV; I've tried a Radeon HD 3450 but doing the same thing this 5450 is (thats why I bought the 5450) I've reformatted the PC -REFORMATTED the PC just to make sure I haven't mucked up the registry or something with all this adding different cards and drivers!!!


I'm running 32 bit Vista with a Q6600 4gigs of DDR2 800

First thing I was going to suggest was the cable.


I'm reading that it looks good with VGA, right? Have you tried a HDMI/DVI monitor that can do 1080p, and does it look right on that? It seems like it may be the TV and the specific setup on that. Can you describe what looks bad? Is it pixellated, or is the color just "wrong"? I'd start with any settings for noise reduction or any enhancement, and turn them all OFF. Also, try 59Hz.


I'm not thinking anything is wrong with the video card, as you have the same symptoms with 2 others.

Thanks for the reply...I think pixellated is probably the best way to describe it...The font has some fat letters where others are not....The color is fine I think...Just real bad resolution...I have not tried another monitor, and I was thinking the very exact thing you said; looks like its in the TV...Will try the things you just said...will get back to you..Thanks...P.S Yes,it looks pretty good with VGA...

I think it's Samsung that requires you to use a designated HDMI input for your PC whereby it doesn't OVERSCAN the input but takes it as 1:1... read your Samsung manual and let us know.

Yes,you are right..Samsung wants you to use the "HDMI/DVI" port for HD PC input,but I've tried them all and they look the same....And Samsung calls 1:1 "Wide Fit"....I've tried different refresh rates and all kinds of stuff...

Here is a link to the actuall TV

Maybe someone will see something in the features that will tell them something...Thanks...

I have the 40" 530, with an ATI 4670. Looks ok to me, but its the only one I have...


My settings:


Catalyst 10.6


- [email protected], (PAL TV)

- RGB full 4:4:4 pixel format

- overscan at 0%


I find i have to install Levels Wizard 0.5 to get consistent black levels across HD and SD output. Your 5xxxx shouldn't suffer from that problem.


TV:


- Dynamic contrast Low

- Edge enh off

- Digital Noise Reduction Off

- Picture size- Screen Fit

- HDMI Black Level - Normal


One thing that definitely does make some changes is using the rename feature on HDMI/DVI input to "PC", when outputting 60Hz from the computer. This disables pretty much all TV image processing and just displays the raw image from the PC. You might like to experiment with that. Personally I like leaving some of those TV features on.

I own a Sony, but will take a crack at this.

"Wide Fit" sounds like a stretch mode to me.


Googling around- "screen fit" is for 1:1 pixel mapping
