Hi,I'm trying to set up a Test Pattern Generator from the VIP. I'm using a Cyclone III Development Board with DVI adapter. My problem is, that the monitor shows no pattern. The resolution is 1680x1050. I used the following settings: External PLL Clock: 119MHz Hor Blank: 160px Hor Sync: 32px Hor Front Porch: 48px Hor Back Porch: 80px Ver Blank: 30lines Ver Sync: 6lines Ver Front Porch: 3lines Ver Back porch: 21lines I take a few pictures and attached them to my post. Hope somebody can help me. Thank you!
Hello again,in the meantime, i tried another system unseccesfully. In Qsys I took a Clocked Video Input and gave it on a Clocked Video Output, so that i get a loop through. For the settings I take the DVI 1080p60 presets. The Video Clock comes from a PLL and the System Clock is 125MHz from Y4. Anyway I don't get any picture out of my DVI port =( Besides I measured with a scope at measuring point V on the Bitec DVI Card. On the input site, I could see a vertical sync signal. On the output site was nothing... Now I thing that I have overlook something on the board. Thanks for help!
