I tested the analog RGB input with an AccuPel HDG-2000 HDTV calibration generator. The type of signal supplied to the VGA connector must be correctly specified in a menu because there are a number of compatibility issues.
If the Computer option is selected the VGA connector is compatible with RGBHV signals with positive or negative HV sync polarity, but the RGB signals must not include Bi-level or Tri-level embedded sync—else the black level cannot be calibrated correctly. In addition, the displayed aspect ratio is limited to 4:3 (1.33:1), so the Computer mode cannot be used for HDTV.
To use
analog RGB signals from an HDTV set-top box, the Video GBR mode must be selected. This produces a 16:9 display. However, in this mode
the RGB signals must have Bi-level or Tri-level embedded sync, which means the VPL-HS10 is not compatible with the 1080i output of the RCA DTC-100 HDTV receiver. In addition, 1080i signals will not work properly if positive or negative HV sync signals are present on the VGA connector, and 720p signals will not work if positive polarity HV sync signals are present
. So with some products you may need additional adapters and breakout cables to create just the right mix of RGB sync signals. Fortunately, most current HDTV set-top boxes include YPbPr outputs, or even better, digital DVI outputs.
Pour moi qui compte envoyer le signal de TPS en RVB, ca sent a plein nez l'extracteur de synchro de Remy et Laric.
Mais comme je ne connais rien a cette histoire de Bi-level or Tri-level embedded sync, je m'abstient pour l'instant, je fais juste passer l'info.
