***SOLVED***

Installed catalyst 10.2 - max res 640x480

Then installed catalyst 11.5 - All HDTV resolutions are now showing.

 

 

 

 

I have a 4850 using the component dongle hooked up to an ol 40" RPTV.  (TW40x81).   

I had it working at 1080i for ages, but i recently had to reinstall wondows 7, and now i'm having problems.

With the default win7 display driver, i DO get 1080i working.  But as soon as i install the newest ati catalyst drivers, the screen just scrolls horizontally very fast, and i can't really do anything with it.  

 

I know it's possible to get it working as i set it up before. I remember having to use a second monitor at the same time to make some adjustments but can't remember what i did exactly.

 

I'm just wondering why the default drivers work but it screws up as soon as i install CCC?

Also, i remember before there was an hdtv section in the options, but now i dont see this section at all.  I am using an lcd monitor as well and trying to switch between the two while i am setting it up.

 

Any help would be appreciated

 

Thx,

Colin

 

 

EDIT 1:

I found these custom resolutions that will work with my TV.  Is there a way I can add them using CCC?   (These are made for powerstrip apparently)

Here are the timings from my backup. You should just be able to paste them into Powerstrip.

One thing to note is that my 40X81 was pretty extensively tweaked in the service menu to minimize overscan so you might need to adjust these a bit.
