@ -209,14 +209,13 @@ With the <strong>pgm_panel true</strong> setting, the driver will fix your panel
This option only has an effect if you have a card with supported TV encoder chip when you use TV out modes. When set to <strong>true</strong> it provides a <strong>'tweaked'</strong> dualhead clone mode for singlehead cards and dualhead cards using singlehead modes on TV. Because this special mode can possibly destroy old VGA monitors it's disabled by default.
<ul>
<li><strong>false:</strong> (default setting)<br>
If you select <strong>vga_on_tv false</strong> the driver will automatically shut-off your VGA monitor (by means of special internal DPMS settings) when a TVout mode is enabled on the head the VGA monitor is connected to. This means that on singlehead cards and on dualhead cards using singlehead TV modes your only output will be on TV. This is the standard way of doing things.
<li><strong>true:</strong> With this setting VGA output on a head is enabled concurrent with TV output on that head: that is if you select a TVout mode. This setting is a 'tweak' because the modeline used to drive your VGA monitor is the same modeline that is used for the TV output. This means that the VGA picture positioning is probably a bit odd, in some modes it might distort somewhat, and the refreshrate will be 50Hz for PAL modes, and 60Hz for NTSC modes. Make sure you only enable this tweak if you know your monitor supports down to 50Hz refreshrate, and preferably has a failsafe built in that blocks output when out-of-range signals are sent to it (almost every newer monitor has this feature).<br>

<p><h2>Changes done for each driverversion:</h2></p>
<p><h1>head (SVN 0.62, Rudolf)</h1></p>
<p><h1>head (SVN 0.63, Rudolf)</h1></p>
<ul>
<li>Added capability to driver to run without an INT assigned. Driver will now automatically disable the 'Sync_to_Retrace' function if no INT was assigned instead of not loading/running at all;
<li>Fixed PLL reference recognition (used for refreshrate calculations) and dualhead detection for a number of 'newer' cards: most notably for a lot of GeForce 6200 types! Code is rewritten so it's much less breakable when new cards are added to the supported list in the future;
<li>Added TVout support for Brooktree BT868/BT869 and Conexant CX25870/CX25871 TV encoders: NTSC and PAL 640x480 and 800x600 Desktop modes are supported, NTSC VCD 640x480 and DVD 720x480 Video modes are supported, PAL VCD 768x576 and DVD 720x576 Video modes are supported. Singlehead and GeForce2MX 'dualhead' cards should work perfectly while newer dualhead cards only display a testimage on TV in all modes for now. Still in progress...
<li>Added TVout support for Brooktree BT868/BT869 and Conexant CX25870/CX25871 TV encoders: NTSC and PAL 640x480 and 800x600 Desktop modes are supported, NTSC VCD 640x480 and DVD 720x480 Video modes are supported, PAL VCD 768x576 and DVD 720x576 Video modes are supported;
<li>Added 'force TV output signal type' (called tv_output) to nv.settings: Now you can select Y/C or CVBS output manually in case autodetection fails for your TV set. That might happen in case the TV and/or card manufacturor didn't adhere to the impedance specs that exist for these signals;
<li>Added detection for two new cards: Geforce 7800 GT PCIe (ID 0x0092) and Geforce 7800 GTX Go PCIe (ID 0x0099). While these cards are reported to work, please note that acceleration for these cards is yet disabled;
<li>Added 'force VGA output ON while TVout enabled' (called 'vga_on_tv') to nv.settings: Now the VGA screen is disabled by default for a head outputting to TV. You can turn it on however using this new preset setting. Note though: doing that is considered a tweak which might damage your VGA screen (if it's an old one);

<li>Added custom modeflag for users to be able to select TVout head on a 'per mode' basis. The Dualhead Setup preference panel needs to be updated (to a version newer than 0.03a) to correctly issue this flag;
<li>Added rudimentary NV11 CRTC2 FIFO watermark/burst-size programming to remove/minimize vertical distortion stripes occuring on some cards due to data fetching errors (because of limited bandwidth);
<li>Modified NV05M64 (TNT2-M64) watermark/burst-size programming to be executed independant of coldstart feature.
