Problem
The Leadtek PX7300GS TDH is locked onto Clone Mode and this cannot be changed.

Reason
The Leadtek PX7300GS TDH VGA card only supports one DVI and Analogue display device. 2 Analogue devices cannot operate normally when used together. This is not a firmware problem, as previously reported, but a limitation on the technical specifications for this VGA card itself.

As can be seen from the above PX7300GS TDH card there is one Analogue D-Sub connector and one DVI connector…

1. Analogue D-Sub connector
2. TV OUT
3. DVI connector

Solution
The following conditions prevail for use of this card with nVidia nView settings…
1. TV-OUT + D-sub CRT = nView will work
2. D-sub CRT + DVI LCD = nView will work
3. DVI LCD + TV-OUT = nView will work
4. D-sub CRT + Analogue LCD or CRT by DVI Converter = nView will Fail - Limitation

For use of this card for Dual Monitor Support, a DVI LCD panel and an Analogue CRT or LCD must be used. Using 2 Analogue CRT or LCD Panels with one connected to the DVI connector with a D-Sub to DVI converter will not work properly and will have the limitation of being locked n clone mode.
