Hi, I have an RV610 card attached to an LG 22LH2000. The LG 22LH2000 has a 1366x768 native resolution and does have VGA and HDMI but not DVI. The Radeon HD2400 does have VGA and DVI but not HDMI, so I'm using a DVI-HDMI converter. When I use the VGA output everything works fine, but I don't get a 1:1 pixel mapping because I have to set a 1360x768 or 1368x768 resolution and the monitor is not smart enough when using vga. Instead when I attach the monitor to my laptop's Intel GMA45 HDMI output I can get a 1:1 pixel mapping even using a 1360x768 resolution. Unfortunately when using the HD2400 DVI output the monitor does not show anything, at least after loading the radeon module. In fact when loading the bios or starting grub the DVI output works flawlessly. nomodeset does not help. I even tried setting another resolution with xrandr (it automatically set 1920x1080i, but I tried 1360x768, 1280x800, 1024x768 and 800x600 and it still does not work).

Distro is Debian Unstable amd64 with kernel 2.6.39 and xorg-edgers ppa. It's the only monitor I will be able to use for a couple of months, it's critical for me to get it working.

Thank you
