Yes, you are right. On my Sony it is called "Täyskuiva" (in finnish), when I had not enabled it, thie TV did overscan IIRC. > But having overscan it means that having the 1:1 mapping is a bit harder. > You need to find out how much is the real visible resolution and define X- > screen to that resolution. I'm not sure what you mean by the above, surely you need to setup X to use the native resolution of the panel? Perhas you meant something different, as I did notice when I did my setup; that fgrlx (yuch, I'm an user of the dreadful fglrx) does a terrible underscan by default, becase it reports a larger screen area trough the HDMI that is actually used (?). I'd assume that nvidia, intel & perhaps some others do this better by default. It is beyond me why an ouput that is used for a digital display uses any kind of over/underscan, but that really was the case. Then I stumbled on this: <http://www.phoronix.com/forums/showthread.php?p=36734#post36734> And got 1:1 mapping at all refresh rates ever since. Thoguh, I still get terrible tearing - I've heard that the radeon driver should be better in video use, but I couldn't get it to work on my card, and I also need DRI... I should've bought nvidia, damn. I used a small program called lcdtest to test the 1:1 mapping. Believe when I say you do notice the difference =). Also I use a desktop and it is drawn exactly to the edges as it should be. -- -- Ville Aakko - ville.aa...@gmail.com _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
