Hello All,

previously i worked  on 800x600 HDMI. that was running successfully after too many enhancements. :)

now my current project is based on VGA 1024x768 to 1280x768  resolution or 720p at 60 -72 hz . for displaying images .
i don't know much about VGA signalling.
so my question are:

1. How to manipulate VGA signals in HItex A5 board without changing HDMI decoder (if change is require it's also ok).

2.The pin-out  for 7" TFT can be corporate for VGA  ?

3.Is there need of  any decoder IC  (like TDA19988 for HDMI  ) for VGA signalling if yes  please share the details.

4.description for enhancing high resolution upto 720p if possible for both HDMI and VGA.

5. reference for VGA Transmitter.



thanks for kind reply.
