ATI HD3200 and HDMI to LCD TV

Hi all,

I have just finished installing Arch Linux on my media PC. This is based on ATI's 780G chipset and has HD3200 integrated graphics with an HDMI out. I have my LCD TV (Sony) connected via HDMI and this always worked well with Windows but with Arch Linux I get a fixed resolution in Xorg of 700x480 and xrandr doesn't report any other resolutions. If I connect with a VGA cable it works great, but I would prefer to use the HDMI cable so I can get audio over HDMI too.

Any thoughts? I've hunted through the wiki and forum, but not seen anyone else have this issue. I am not using KMS as it is strictly stated that it's not supported with the radeon driver (which I'm using in instead of radeonhd or catalyst).

Thanks,

Mike.

What driver are you using, Catalyst or xf86-video-ati? (the open source driver) I have the same card and I'm using the open source driver without an xorg.conf and can connect it to my tv via HDMI with full 1920x1080 resolution.

I am using the open source driver, not catalyst. What motherboard are you using? Is it a 780G chipset one?

Yes mobo is a 780g chipset (can't remember exact model but think it's gigabyte ga-ma78gm-s2h or similar to that)
All I had to do to get HDMI output working was make sure it was selected as output in BIOS.
Are you using an xorg.conf? If so try removing it (make a backup first) then try rebooting

Hmm. This is odd. My motherboard is very similar to yours. I have HDMI enabled in the BIOS and it does output to it, just not at full resolution. Maybe I need a bios update... Will try that and see if it changes anything.

Not using any xorg.conf at all so far, but if anyone knows anything I can put in there to help then please let me know.

Thanks,

You say you're using the radeon driver? Use xf86-video-ati instead (I'm pretty sure they're different), as I heard it's more up to date. ALso maybe use th -git ones.

I've got the same issue.  I'm running the xf86-video-ati driver without an xorg.conf.  I've got a radeon HD3200 (rs780M).

Using the gnome utility, i can see the TV and it's correctly recognized, but I'm getting no audio or video on the screen.  Also, rebooted and was able got video from the BIOS on the TV, but as soon as the kernel starts to load, nothing.

I reduced my resolution to 1280x720 and selected "mirror screen", which appears to work, but video never does show on the TV.  Bleh. This is HDMI btw.

Hmm. As far as I'm aware, the xf86-video-ati *is* the radeon driver. However, I have tried this and the radeonhd driver to no avail. I can't try the catalyst driver as this won't install with the current updates to arch linux (some conflict on Xorg), so not been able to go that route.

I do get a display over the HDMI connection, but it's just locked to 720x480 resolution and I can't get a 720p resolution on it (1384x768) as I can with the VGA lead. Am using KDE and krandr sees the display and 720x480 res, but won't let me change to anything else....

@doorknob60 - what are these -git packages?

Probably tried this but just checking, after you've plugged it in have you gone onto display settings in KDE system settings and tried to change the resolution?

Yup, tried this multiple times, but no cigar.
