I wasn't sure if this belonged in the Rear Projection Units section or the Calibration section; my apologies in advance if this is in fact the wrong area for the query...
I am still (rather successfully, save for a lamp change in all the time we've had it) running a Sony SXRD rear-projection display circa 2008 as my primary viewing screen, but from the very beginning something has bothered me about this set with regard to picture settings and when they're adjusted for our Cable Box input (component; "Video 5" slot). While my "Video 6" (HDMI) input has been adjusted via setup discs for Blu-ray and DVD playback (source being an Oppo BDP-83 BD player), with corrections made for Sharpness, Contrast, Color, etc., I have always been stumped with how to adjust for the cable box input of the set...
Just last night and the night before, I tried fiddling again with some of the basic picture settings while watching cable transmissions -- both standard def and high def -- and for the life of me, I cannot see ANY changes being made when I adjust certain picture parameters, notably SHARPNESS. To be exact, I tried running the Sharpness control QUICKLY from minimum to maximum while keeping a fairly static image on the screen, and there is absolutely NO change to the image to my eyes. Yet, on my HDMI input, when I calibrated for Sharpness using the HD Essentials Blu-ray test pattern, you could clearly see the white lines getting "fuzzy" and "busy" as you adjust the Sharpness control for optimum setting, as you should...
Still, on my Video 5/Component input for the cable box, I can't see the Sharpness changing one way or another; someone once suggested to me that this could be due to the upconversion the TV is doing to the incoming 1080i signal from the set top box (to the TV's native 1080p resolution)...but whatever the case may be, how do I establish Sharpness for this input/source? Should I just leave it at the default 50% setting, where I have it now?
Further -- is there a good way to set parameters like Color and Brightness for a cable input without using test signal generators or hooking a disc player up to the input? Is there something I should be looking for in broadcast material that can aid in setting these controls?
