Hi All,
We are using THS8200 IC for converting LCD parallel signal to VGA on phyBOARD-WEGA-AM335x(SOC AM3359).
On VGA monitor we are getting on vertical stripe.
If i moves the QT application to that area, shadow is coming on the VGA monitor.
Please find attached jpg for problem.
I am using below XGA resolution.
XGA 1024 x 768 @ 60 Hz pixel clock 65.0 MHz
Horizontal Timing (pixels) Vertical Timing (lines)
Visible area 1024 768
Front porch 24 3
Sync pulse 136 6
Back porch 160 29
Whole line/frame 1344 806
Bellow are the register values of THS8200 IC.
