Im trying to adjust my HD CRT RPTV (Toshiba) to set brightness/contrast and would be very greatful for some advice.
Im running a HTPC (9800pro based through a key-digital transcoder).
I have the phillips test gen, dve (NTSC only), thx optimizer. Im using the ati cat 5.10 drivers (control panels) and am trying to calibrate for DVD's using VMR9 renderless (zoom player, ffdshow, dscaler5006).
I'll reference the THX optimizer here because it was star wars ep III that started me on this new quest, Ive recently begun watching DVD's in near dark whereas previously i'd have a very low wattage globe (11w PC) operating in the rear of my HT room (behind the viewing position).
I noticed that on scenes that were supposed to contain nothing (ie. were supposed to be black) such as the black screen between the menu and the fox logo comes up, I was seeing dark grey (looked black in a slightly lit room). So I started messing with the THX optimizer (afterall it was already in the drive) and this is where my troubles began
Im adjusting brightness, in order to be able to see BTB my brightness settings need to be high enough, either through the display itself or through the brightness setting on the video card driver (for fullscreen3d) that I see this grey (on a blank screen) when its obviously supposed to be black (ie crt's off).
ATM, I like the idea of the screen being black when its not displaying anything, but I am concerned that im missing out on picture detail by setting my brightness low enough to do so.
When I set it to show a blank screen as total black (no difference between the TV being on or off) the THX optimizer logo (words THX) are just visable, I can *just* make out the 7th black box (value 21).
I am open to any advice! :-) Should I cut my losses and calibrate so I can see BTB at the expense of loosing my 'black - empty screen' ?
PS: The philips test pattern generator seems to only be good for calibrating the desktop (im assuming overlay) and not vmr9 renderless which on my system is different to vmr9 windowless.
