Christer, I think you have correctly identified the issue. The timings in the LCD/TV registers don't match the timings that are being used to calculate the Overlay Active offsets.
Try this.... it should work unsigned int temp = INREG(0x60000); i810Reg->OverlayActiveStart = (temp>>16) - 31; i810Reg->OverlayActiveEnd = (temp & 0x3ff) - 31; -Matt -----Original Message----- From: Christer Palm [mailto:[EMAIL PROTECTED]] Sent: Friday, January 18, 2002 6:06 PM To: [EMAIL PROTECTED] Cc: Sottek, Matthew J Subject: Re: [Xpert]i815 overlay output revisited OK, I now understand (I think) why this (and other related things) doesn't work as I expect... I now realize that the i815 has a separate set of registers for the digital out timing. The i810 driver never touches those registers, so they will be left at the default 800x600 mode programmed by the BIOS at system initialization. This also explains why I at all get a picture on the TV regardless of the X11 modeline, even though the driver never talks to the TV chip, which has puzzled me for a while. I'm adding this stuff to the driver right now. My goal is to keep the TV-out chip stuff generic, so that it could be used with other drivers/TV-out chips as well. Suggestions and wish-list items are welcome! -- Christer Palm _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
