HDMI Problem with ATI Radeon 4200 (No Sound, 4:3)

I will try to best describe the problems and the hardware that I have.
Just built a new system and I was trying to have it to where I can switch between both my computer monitor and my VIZIO HDTV so that I can watch my blue ray movies directly from my computer on my HDTV. However, I haven't had any luck at the moment.

ASUS - m4a785td-v evo has ATI RADEON 4200 with HDMI
AMD Athlon II X4 620 Propus 2.6GHz

I've hooked up the HDMI Cable to both ends and I get a picture on my TV but it does not fill out the entire screen, looks more like a standard 4:3 with the black bars on the side. Second issue is that no sound is coming of the HDMI cable. I've installed the HDMI Realtek Drivers still doesn't do anything. I have an option for both ATI HD AUDIO rear output and HD Audio Rear output, I've tried both and no sound on the Vizio TV, if I switch to the ATI HD Audio I no longer have sound coming out of my speakers, so I have to toggle back and forth to get sound, but still no sound coming out of the TV.

I also do not have an option in catalyst to enable HDMI as a display option I only have DVI (1), could this be the reason I can get a wide picture on the TV?

I almost forgot. When I try to install the drivers for the ATI HDMI Driver from the ASUS DVD it constantly tells me I have to install the audio driver first, even though I install it restart computer and still can not install the ATI HDMI DRiver off of the CD. So I went looking on the net for the driver installed it, and still nothing.

Here are a list of drivers that are currently installed:
ATI High Definition Audio Device: 5.0.50000.17
VIA High Definition Audio 6.0.1.7200
ATI Radeon 4200 8.661.0.0

I've installed and re-installed all the drivers, and tried to find a problem but still same outcome. As I am posting this message I just remember I just uninstalled the Newest Realtek High Definition Audio Driver 2.58 (5.10.0.5612). So it is currently not displayed in my Device manager.

Thanks for any and all helo

Are you using some sort of adapter, or another medium between the TV and the VC? There have been many problems like that, and no solution I am aware of.

Did you try downloading the latest drivers from AMD? I find it hard to believe Catalyst 8.6 is the latest version for the HD 4200 series. I'd guess it's 9.10 like the rest of them.

Hi,

I have a similar problem to you with an ASRock M3A785GXH/128M motherboard - I get a display which will not fill the whole screen (similar to what you describe as 4:3). I know the TV is OK, as my laptop which has onboard Nvidia 8200 fills the whole screen at 1920x1080. Not sure what the solution is at the moment (am trying other OSs to see if it is a driver problem). I am using Windows 7, and it works OK during installation which leads me to think it is a driver problem.

Cheers,

Dave Harrington

I've got the same issues with control/management of the HDMI output:

It seems like the HDMI output doesn't have any software controlling it, it's just a slave to the primary video output (in my case DVI).


The problem I have is because of the default underscanning with the ATI drivers - they are set to underscan by about 10%. I know this because I found the option to turn it off by installing Windows XP and moving the slider in CCC. However, there is no option to do this with the Windows 7 software. There may be a way to tweak it using some third party software or perhaps it needs a new monitor driver. I think ATI have got it wrong in a big way with this setting - sure, let it be changeable - but for the vast majority of modern TVs it is useless as they do not overscan by default (which this setting is designed to correct).

Thanks for your reply daveharruk,

Not sure I totally understand, but sounds like it's down to firmware/drivers so we'll have to wait on the vendor and hope they invest in writing some new software.

Cheers,

Dave

The problem is all sound related now...I do not get any sound from the HDMI output from my PC to my TV. I've all the drivers and still nothing works. What gives? I thought it was supposed to be plug and play and plug, experiment, experiment some more, start forum topics, and still no play.

I had this problem and the solution was bios setting on the motherboard. These settings were not intuitive. My motherboard was a Gigabyte with HD 4200 on-board and a quick call to their customer support gave me the correct bios settings. My issue was identical, I had video on the TV over the HDMI cable but no audio.
