I am trying to use rgb2dvi digilent IP for my first HDMI project (in xilinx FPGA). For now I just want to demonstrate a simple picture in display.
rgb2dvi digilent IP has an input called pixelclk. What is this clock?
For 800*600 resolution video, what frequency clock I should connect to this input?

@aminpix,
The answer depends on how you are generating the vdo data.
This clock should be the clock with which the RGB (24 bits) data is generated as well as the the HS, VS and VDE signals.
If you have used the dvi2rgb core too, you can connect the pixelclock output of this IP to the input pixelclock of the rgb2dvi IP core.

Please read the Digilent spec RGB-to-DVI (Source) *.* IP Core User Guide available at GitHub.
