thank you, Vasile

Check out the Virtex-5 based Advanced Video Development Platform from IPT. This contains an Analog Devices ADV7321 DAC chip, which is perfectly capable of outputting 1920 x 1080 analog video in RGB or YPbPr.

MH.
VGA 1920x1080 and HDTV 1920x1080i aren't the same thing.
The HDTV-signal is 60Hz interlaced, and runs at a pixel-clock of 74.25MHz (60Hz), or 74.178MHz (59.94Hz.)
Are you just looking for a board with VGA-output? Or do you need a board with both VGA-in (ADC) and VGA-out?
If it's just VGA-output and nothing else, then you have plenty of choices. Xilinx and Altera have demo/evaluation/kits with a bunch of random peripherals/RAM, and many of them have VGA RAMDACs capable of
1920x1080 output. Either a TI, Analog Devices, Chrontel, or other RAMDAC. (Nowadays, RAMDAC products have evolved into integrated DVI-D transmitters and VGA DAC functionality on one-chip.)Boards with full-path VGA in/out are more specialized and expensive.
