Hi, I have PNY 5700LE AGP graphics card, which uses NVIDIA chipset/drivers. Using RGB output to a standard HD tube monitor on the primary port, and DVI output to the HS20 on the secondary port. Operating in clone mode (or Dual mode for that matter), I am seeing a max phyhsical resolution of 1024x768 projected on the HS20. The desktop is set for 1280x768, and it "pans" within the 1024x768 allowable window. Very annoying. The primary is working fine at 1280x768 RGB. The driver is telling me "Your flat panel display has a maximum resolution of 1024x768," which is apparently why I'm stuck with that resolution on the HS20. I can't find any settings or register entries to change this. PNY is telling me the Sony has an EEPROM value somewhere that conveys the projector geometry over the DVI port, while Sony is telling me the projector will revert to 1024x768 mode when it receives an 85+ Hz Vertical Refresh rate. (Yet, the HS20 info menu is indicating a 60 Hz signal is being received). I've seen some discussion on this issue in the AV forum, but can't find any crisp suggestions as to what to do. I have the latest drivers installed (Nvidia 6.1770) and this HS20 is fairly (received 1 week ago) and should have up to date firmware. From what I can see, the DVI on the HS20 is excellent. Just need to get it working in WXGA mode. HELP! TY.
