Getting native (1366×768) resolution through the DVI input
For Radeon cards only!
First you need PowerStrip, you can use the free trial which will last forever. After you have installed PowerStrip right-click its icon in the systemtray, choose Display Profiles -> Configure. Click ‘Advanced timing options’ (if this is greyed out and you are using Omega drivers, try getting the offical or the DHZeroPoint drivers).
Click ‘Custom Resolution’ and feed the following data into the fields.
Horizontal:
Active Pixels – 1368
Refresh rate – 48
Front porch – 30
Sync width – 128
back porch – 154
Vertical:
Active Pixels – 768
Refresh rate – 60
Front porch – 8
Sync width – 3
back porch – 22
The pixel clock should now show around 80,700.
Press ‘Add new resolution’, you may have to restart for the resolution to be added to the display driver.
After restarting change to your new resolution in Display properties, if the picture doesn’t show on your Philips TV, try turning it off and on again, also make sure it’s set to DVI input.
You encounter two black bare on either side of the screen, I have not been able to find a solution for removing these bars, but am always looking for suggestions.
