By checking intel documentation i found that this registers are </font>responsibly<font size="2"> for setting up the progressive/interleave mode. As so im thinking that this registers are not being reinitialize or cleaned. </font></div><div><font size="2"><br></font></div><div><font size="2">Is this possible? </font></div><div><font size="2"><br></font></div><div><font size="2">Since im up for one more test i used intel_reg_read/write to modified the registers and correct the values, to my surprise after writing to all the register the AV shows my desktop correctly.</font></div><div><font size="2"><br></font></div><div><font size="2">My other question is if they need to be reinitialized where in the code shall this be done? I'm up for writing a small patch to fix this issue, just need some one to point me on the right direction.</font></div><div><font size="2"><br></font></div><div><font size="2">Thanks</font></div><div><font size="2">--Paulo Louro</font></div><div><br></div><div><br></div><div><br></div><div><div><div dir="ltr"><div><div dir="ltr"><div><div><div><div dir="ltr"><div><div><br></div></div> </div></div></div></div> </div></div> </div></div></div> </div></body> </html>
