Yes i'ts realy is.  

The problem in LAncelot board, not in project.  You can solve it in 2 ways  1. Just use TFT monitor http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif ) 2. Look at the schematic of Lancelot board - need to set or clear some input at video DAC  (i don&#39;t know exactly what need to fix in Lancelot because i make my own Lancelot- like board where i do correct connection to videodac)  Be sure - i check this to many times - so you don&#39;t need to change vga timings !!  The problem is only videodac using in lancelot board.      --- Quote Start ---  originally posted by suway1219@Apr 8 2006, 01:17 AM as title..it&#39;s altera reference design  when i fade in the picture,there is some green mask to cover the picture..  is anyone have use this reference design !?  how can i cancel this reset background(change to black)? <div align='right'><{post_snapback}> (index.php?act=findpost&pid=14141)  --- quote end ---    --- Quote End ---
