I can only select 1280x760 to view any content through the D2. Should I just keep it as is or should I try to look for the actual resolution of the display?
I can't find the actual native resolution of the Pioneer anywhere and wondering if anyone actually knows?
Your best bet is to ask in the owner's thread here for your particular model of display. There are quite a few Pioneer display experts here at AVS, so odds are you'll get an answer in short order as to what's the "best" input resolution for your older Pioneer display.
It is not uncommon for such displays to not accept their actual pixel matrix as a valid input resolution. In other cases (e.g., with some older Panasonic panels), you can only get the display to accept its pixel matrix as an input resolution if you build a custom set of video timings. Ask in the owner's thread for your display whether folks using any specialized video scalers have found that necessary. If you find custom video timings are necessary, the D2 can do that. Anthem tech support can help with that if you can get the parameters from one of the folks that's already got some other external scaler working that way. Basically you build the custom timings using an Anthem tool and then upload that as the "custom" output resolution of the D2, selectable in Setup > Video Output.
The 1280x760 that you've already found works may indeed be the best answer given the restrictions your display puts on non-standard input resolutions. Ideally, the display will then leave the missing 8 lines of video black (e.g., 4 black lines each left at top and bottom) as that would mean the display is not attempting to "scale" that 1280x760 input to 768 lines, which is almost certainly bad news. (Scaling between resolutions that are pretty close together like that is just asking for scaling artifacts.)
Note that 1280/768 and 1280/760 are both distinct from 16/9. Which means that at some point the 16:9 content has to be scaled to match those non-square pixels in your display. It is quite possible the D2 can do that better than your display, so this is certainly worth checking.
Also note that many displays assume such non-standard resolutions are coming from a computer rather than a home theater device. As such, when fed such a resolution the display may shift gears internally in the way it does things. For example it may shift to a lower Gamma correction value or may disable the dithering necessary for best home theater viewing. The point being, you need to check to see whether "native resolution" input remains properly calibrated for video levels and truly looks better than just feeding a "standard" resolution to your display.
