phlei,
We would need to get more information from you to help out.
Questions:
1) Are you using one of our display kits or are you just using video-open with one of the available modes for a custom display?
2) If you are connecting a custom display, which is it?
3) Which product of ours are you using?
There are two docs you should look at:
http://www.logicpd.com/do...N_70000161_Rev_A.pdf
http://www.logicpd.com/do...47/1002791_Rev_B.pdf
The second doc is if you are using LogicLoader 2.x, which hasn't been released on all of our kits so it may not quite fit your situation.
VDDEN, VEEEN are used as basically a 'on' signal for power supplies. If you are powering a display directly, this isn't an issue. Power Save is a ADTFT signal and shouldn't be needed here also.
How much confidence do you have in your timing settings?
Thanks,
-Mike
