The challenge we have is that we must do it using the 3 component cables already in place. What we have to work with is:
a. Source signal is VGA/RGBHV.
b. HDTV interfaces are either VGA/RGBHV, Component (YPrBr) or HDMI
c. Cable link between the two is component (3 cables)
Test 1: VGA to Component (YPrBr). Using a converter the VGA signal is transcoded to an YPrBr signal so we can use the component interface on the TV side. I tried the Key Digital KD-VA5 but found it was not working at all. The component interface on the TV is very limitative and it looks like very few graphic cards would be able to sync with it without scaling.
Test 2: VGA to Component (YPrBr). Similar to the first one but now the source signal is scaled to match a "preset" resolution. Your laptop resolution doesn't need to match the TV resolution. A 800x600 coming from the PC can be scaled to match the 480 res on the TV. I tried the Calrad video scaler/converter but the quality was disappointing and isn't user friendly. Actually you have to enter into a menu to "set" the source and destination signal. Might be good in a static environment but not when laptop will change every day.
So my best bet is probably to go with the VGA to VGA option but I am not sure on how to do it. Knowing that the VGA/RGBHV is a 5 cables signal how should I go from 5 to 3 and then back to 5?
Also, am I missing something with the vga to component that would provide a better result?
Any help would be greatly appreciated,
Thanks in advance.
