Solved Graphics Card to HDTV via HDMI Cable Even Possible?

[BeKure]

I am trying to hook up my Radeon 5870 HD to my 1080p HDTV via HDMI cable and not only is the image onscreen slightly blurred, but there is also a black border that is approximately 1" around the entire display. Pardon me if I'm missing something but why even have a card with the option to hook up a HDTV via HDMI if it cannot properly display a picture?

Any help would be appreciated. Thanks.

Hi.

First ensure that you have installed the most recent software\driver for your Radeon 5870 HD.

http://support.amd.com/us/gpudownload/Pages/index.aspx

Then,

Right click on desktop,click\run Catalyst Control Center,on the right side click preferences and select Advanced view.

Now in the left side list select Desktop Management\Desktop Properties,on the Desktop area list click HDTV\1080p Aplly.

Now click on My Digital Flat Panels\Scaling options (Digital-Flat-Panel) and adjust the screen to eliminate the black border.

Have you set the output resolution to your HDTVs native resolution? It should be in your AMD Catalyst controls IIRC. My Nvidia card did this also. I had to set it to my HDTV's native resolution. This is most likely causing your issues.

My resolution is 1360*768 on my LG 720p 37". It doesn't default to it automatically.

Thank you anyhow but this didn't work very well. I was able to manually adjust the scale but the scale still didn't line up with the corners of my HDTV the way that it should, plus the picture is still blurry and looks horrible in my opinion.

Thank you for your suggestion and I would love to try this but I have no idea how to go about doing so.

hi i no panais covered this in his post but this is from ccc help hope it helps

Adjusting Image Size and Position for Digital Flat-Panels (Digital TVs)

To adjust black borders surrounding your display area, use the Underscan/Overscan slider to adjust your image so that the borders are no longer visible.

Navigate to one of the following pages:
Standard View—Desktops and Displays > My Digital Flat-Panels > Scaling Options (Digital Flat-Panel).
Advanced View—My Digital Flat-Panels > Scaling Options (Digital Flat-Panel).
If more than one digital flat-panel is available for your computer, use the display selection menu at the top of the page to select the display that you want to configure.
Click and drag the Underscan/Overscan slider to adjust the overall size of the image on the display.
Note: The slider is not available for display configured to use a custom or the default optimized timing mode.
To ensure that forcing a custom HDTV mode does not create conflicting resolutions, select Use the scaling values instead of the customized settings when the desktop resolution does not match your DTV resolution. For more information on creating and applying custom HDTV modes, see HDTV Support.

I had the exact same problem with my new ASUS monitor. Connecting it via HDMI to my 6950, would never go full screen unless i did what Pansis suggested, but patches were still blurred and looked funny, while others were fine.

i then connected it via DVI and it was fine. I later did some research and found out theres some know issues with AMD cards and HDMI, with lots of unsolved issues.

Try a DVI to HDMI cable, may give better results.

Wow, thanks for that bit of info. The fact that this has been a problem with AMD for quite some time really makes me want to lean toward Nvidia when I upgrade again. I will just try to hook it up a different way. Thanks again.

Don't manually adjust. If its an HDTV, on HDMI, it will tell the AMD control center what its native resolution is.

On the desktop, right click, then select "AMD Catalyst control center.

Find the resolution/display tab, one of the outputs should say Native next to one of the resolutions.

Tried DVI to VGA and the display looks great. I'm still bummed that the HDMI cable didn't display the way that it should. I like the fact that HDMI supports both video and audio and it sucks that it isn't working correctly with AMD cards.

You must have a setting wrong somewhere. Can you post a screen shot of your resolution in the Catalyst control center? I'm still thinking you have an incorrect display resolution selected. Many times selecting 1080P will not display right.

I hooked up my TV via DVI to VGA because for some reason now I can't even get my cursor, taskbar or anything to appear besides the desktop wallpaper
via HDMI. Here are the screen shots you asked for.

 

[raven2510]

Hum...you should be a 1080P 60Hz. Surprised that doesn't work. My buddies setup is this way. I just checked with him. What resolution is it trying to set to on default?

I can't tell because when I switch my HDTV input to HDMI for some reason now I can't even get my cursor, taskbar or anything to appear besides the desktop wallpaper. That's all I see when I switch to HDMI is the wallpaper/background. No keys work nor does the cursor work. It's almost as if the HDMI function is completely broken now.

Have you tried reinstalling your drivers for the card. If your having all these issues, its more than just the output. I would try the drivers first.

 

[scrooge]

i have the ( ATI Radeon HD6800 Series ) and had the older cards and never had no trouble with it.
take a look at this screen shot and see if that helps.

I have tried re-installing the drivers multiple times. I am thinking that I just may have a faulty card.

 

[scrooge]

have you tryed the hdmi cable on another device ?
maybe the cable is bad.

The Radeon 5870 HD has HDMI port so "normally" the best connection is HDMI-HDMI.


Connect the HDMI cable in the HDMI 2 of your T.V.


In some hd television models the correct computer connection is the HDMI 2.


Try this and post back.
