Massive problems with radeon DVI to Hitachi 57swx20b

Basically my problem is that I'm using my main pc as my htpc. It's a somewhat high end system (2.4ghz, r9700pro, etc).

I'm going to my 21" sony monitor with vga, and to my TV with a 5 meter DVI cable.

Using powerstrip, I have everything working fairly well MOST of the time, with my monitor at 1600x1200 and my tv at 960x540.

The problem comes when i reboot, or when i enable/disable the tv. For some reason the ATI drivers have chosen to make the TV display "1" and the monitor display "2". Sometimes when i re-enable the tv (by clicking "extend desktop to this monitor"), the monitor switches to 960x540, and the tv switches to 1600x1200, resulting in complete havoc. Neither display likes working at those resolutions. I'm left with 2 black screens.

And now on reboot, i will occasionally have 2 black screens also. Unplugging the DVI at the pc, and rebooting will give me my system back.

How can i stop the computer from confusing and switching these 2 display devices? Am i going to end up having to build a pc just for the tv? I REALLY don't want to do that.

I've been thinking the ATI dvi-component adapter might solve these problems, since it is supposedly meant to do these things. But i just read ATI's website, and apparantly it can't be used in a dual monitor config, only single. I don't want to pay $30 + $15 shipping for something that won't really help.

Try connecting just the HDTV to the DVI port, rebooting, making this the primary monitor. Then add the secondary monitor and activate thru the displays page of the advanced properties page. Also try running in clone mode as opposed to 2 separate monitors.

Well i managed to switch it to clone mode, but i guess that means i have to run at the same res on both screens. Unless I'm missing something, I don't think that is going to work very well for me.

I run a vga computer monitor as the primary with the FP as the DVI connected secondary. Never had a problem with these assignments changing either. I make sure that when I use extended desktop onto the secondary that I disable that seting before I shut down, works flawlessly.

Resolutions are diferent for the VGA and DVI....

Seems like you may have a setting problem?

I think if i disable the TV as a secondary before i shut down, that would probably cut my problems in half

I'm just wondering if there is a more elegant method I'm missing.

Actually don't need to shut down the secondary monitor, just uncheck the box that says " use this device as the primary monitor" With that done and the CRT set to primary you should be able to boot or reboot the system without any problems, the CRT will be where you log on and where the desktip Icons reside.
