|I have a Piano projector and when using WinDVBlive I always get the impression as if the picture is not sharp via the DVI connection. The problem is that DVI has a fixed resolution (for me 800*600) which avoids the projector to do interlacing ;( .|
|I know from other discussions and chat about WinDVBlive it is not very strong on interlacing.|
|DVI is the best solution because it uses digital signals. Normally the picture should be clear and crisp. If you have some problems with this you should eliminate all possible troublemakers like long wires, to high frame rate, interlaced source|
|I don't know but is this also wrong if you play a dvd?|
|Hmm, i have not found any lengthlimit.|
|may be the sync is inverted (wrong polarity) or not on the right wire. YCbCr is Componentsignal. Not as popular as Y/C in germany for normal people. If you have read the link in my previous posting you have also found som links to converters for translating rgb2YCbCr and vice versa.|
|Has the "piano" RGB or YCbCr inputs? this is a big difference|
|b) this would i prefere. it uses only 4 wires and has the original resolution. if this dont work nothing will.|
|b) to dark means to much loss, to long wire but compensable with higher amplification. to unsharp means that you have a bad cable with to much loss in the high frequency area, wrong output driver or wrong impedance. But wrong impedance at 11 meter long cable means also ghostpictures and if you dont have some it is only loss.|
|Yes, no. Yes, i would play with the parameters for the graka, no, i don't know if it is possible to get better picture quality with WinDVBLive. My impression is to let WinDVBLive where it is and to use some of the original soft from tt or soft which uses the sdk from them|
|Or stay away from Win and use Linux.|
|Yes, that's worth a try. RGB over such a long distance is "not the yellow of the egg|
|In general in can be said that LCD- or DLP Projector are best suited for the VZ-47 (VZ-45b) as there is no image flickering on such projectors. If the resolution of the LCD-panel or the DLP-chip is 800x600 the picture quality of the VZ-47 / VZ-45b will be optimized.|
If the resolution of the panel is higher you should check if the projector offers a "window function", which means that it can use only the exact 782x582 pixels in the middle of the panel for the projection of the Visualizer image. It does not convert the image to full resolution (e.g. 1024x768). When the resolution is up converted, there is often loss of quality.
Of course the loss of quality is much worse when the resolution is down converted. For example when the resolution of the LCD-display is only 640x480 and higher resolutions (such as the 782x582 pixels of the VZ-47 / VZ-45b) are down converted to 640x480.
