Since I'm not 100% positive when I'll get back to working with my coworker's set, I figured I'd post the current settings for his set. These settings are subject to change if / when I figure out a way of altering the color primaries to be closer to the REC709 standards (red and especially green are pretty significantly oversaturated). Color primaries are not normally adjustable on most TV's but umr figured out a way of doing it on the A2000 he calibrated, so I'm not willing to give up on this goal just yet.
Anyway, what follows is what my coworker's set is currently using (note that the following assumes you are already familiar with navigating your way around the service menu and making changes in it):
Iris: Auto 2
Hue: Centered (0?)
Color temp: Warm 2
Advanced: All enhancements off
White balance: Unchanged
Power saving mode: On
Color matrix: Custom, left at default settings
(601 for 480i/p;
709 for 720p/1080i/1080p)
Service menu (followed by explanations of what the settings do):
3 R_GAIN 127 (default 128)
4 G_GAIN 108 (default 109)
5 B_GAIN 72 (default 68)
6 R_BIAS 128 (unchanged)
7 G_BIAS 126 (unchanged)
8 B_BIAS 125 (default 127)
White balance - the settings above bring my coworker's set to extremely close to D65 at all IRE's >= 15 or so regardless of iris setting (dE <= 3 and <= 1 at 30+ IRE).
011 col_lum axis_ycp.spf
000 RYB 0 (unchanged)
001 RYR 27 (default 32)
002 GYB 99 (unchanged)
003 GYR 146 (unchanged)
Color decoder - affects brightness of the RGB color primaries and hence the actual colors of the CMY secondaries - the above reduces red brightness a touch to eliminate the very minor red push that existed. Note that despite the set's oversaturated green primary, I left the color decoder's green settings unchanged because the green component of the cyan and yellow secondaries were already accurate when the color of green was taken into consideration.
016 col_lum ycc_ccp.spf
000 CODL 8 (default 6) - 720p
7 (default 6) - 1080i
8 (default 7) - 480i/p
Chroma delay - used to fix colors being horizontally offset from the luma information in the picture - 720p was the worst offender before this fix. Note this isn't the same as misconvergence.
000 UGAM 53 (default 51 on HDMI, default 46 on component)
Gamma - optimizes gamma curve for a more natural / less "contrasty" image (subjectively this also seems to make green and red less objectionable and, more directly, also greatly helps dark scene details).
108 sharp xspp_ccp.spf
014 YFLR 6 (default 5) - 1080i
unchanged - other resolutions
The infamous low-pass filter fix.
Other miscellaneous notes:
- The user-menu and service-menu settings are tuned for use with one another as some of them do affect one another. For example, before the service-menu gamma change, the correct brightness setting in the user menu was something in the 55-56 ballpark instead. Similarly, the color decoder settings are greatly affected by the user-menu color and hue settings.
- I prefer doing the white balance tuning in the service menu over the user menu because the precision for fine-tuning it is greater, though ironically enough, lovingdvd claims he got his A2000's white balance tighter at the lower IRE's than I was able to using just the user-menu versions of these controls.
- Since I last worked on my coworker's set, I played around with the user-menu gamma enhancement setting on my personal GWIII set (a Sony LCD projection set that's a nearly 3-year old model). Turning it up from the default of off does in fact decrease the gamma but it destroys the smooth gamma curve that off delivers. I haven't taken formal measurements to see if the same occurs on the A2000 (I haven't been back to my coworker's place since this test) but I would suspect the behavior is similar. The service menu gamma tweak I listed above reduced his gamma from ~2.6 to ~2.4 and remained perfectly smooth. If you want to go even closer to 2.2, try a value of 54 or maybe even 55 but I personally think (as do a decent number of professional calibrators) the image loses a bit too much 'pop' at that point and appears washed-out on many TV's.
- One more setting I changed on my coworker's set that's definitely a setting specific to his set (though others that want to adjust this on theirs will now know where to be playing in the SM ):
The above offsets the red panel by 1 pixel vertically relative to the green and blue ones to improve convergence. There are settings here for all three panels, both horizontally and vertically (i.e., there are 6 settings total in the TG menu for this, plus other settings whose purpose I don't remember offhand )
26 VSFT_R 2 (default 1)
- I ordered a 70" XBR2 for myself today (9/8) which I expect will probably have a similar (but likely even more extensive) service menu to the A2000. With any luck once I have this set in my hands and calibrated I will figure out more tweaks that are applicable down the line to the A2000's as well.
