You didn't provide line numbers with your listing but look at the third line closely and you will see what might be causing the problem.

You did not provide the relevant part of code. "column" and "row" are outputs and therefore signals, the errormessage indicates you use them in variable assignment (row := ABC) instead of signal assignments (row

Here is my code,here is no errors and warnings, but even no warnings and no errors (i think adv7125 problem) it doesnot work.I have old ML405 board an d it use ADV7125,and monitor is Acer AL1511 used 1024X768,I use LED out for checking whether is reset works or not, and also checked for CLK (LED VGA_R, VGA_G => VGA_G, VGA_B => VGA_B ); C2 : clock port map (clk100MHz,clk65MHz); LED

I had a look at the datasheet at

Maybe you also need to drive the "blank" pin, or the "psave"....

It would pay to check the schematic...
