No, but you can create them very easily: Create a simple image in something like GIMP that has boxes that are 0% white, 50% white, and 100% white, the colour red (255,0,0), the colour green (0,255,0), and the colour blue (0,0,255). Not quite the same as a full test pattern, but it'll give something reasonably decent to calibrate off of. Note, however, that the output equipment has to be properly calibrated itself to calibrate the viewing device; if your video card is putting out severely miscalibrated video (you would need an oscilliscope to actually determine what it is outputting, because how you perceive the displayed image depends on your TV's calibration), calibrating your TV to it will of course put your other sources out. Probably best to use a DVD to fix the TV first, so you end up with (assuming the DVD player doesn't suck) something close to properly calibrated, and then fix the MythBox by generating calibration images (and adjusting the computer's settings) as described above. -- Ian Trider [EMAIL PROTECTED] _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
