thank you for your reply
we put table 82 with a little changes
17 02
00 FC
01 00
02 60
80 11
82 CB
87 80
88 10
8A 0C
But the problem is that we dont get the correct V sync, that comes out of TW8811
we get a divided video, it starts at the middle of the screen (H is correct but the V is wrong)
any other suggestions?
tnx
