Personally I would not use a G70 unless I could use the old firmware. I must turn off the Auto black thigy to remove those horrifically bright bowed lines at the top of the tube. Switch off auto black and adjust the G2 - job done and no lines.
If all I could get was a G70 with new firmware, then I'd sell it and buy a digital!
Just wondering what Probe you where using in the GrayScale example above
as it looks pretty good, or is that with A VPs CMS..
Also how many hours are on your G70 tubes?..
The probe is the HCFR Colormeter (DIY).
No processing or color management for that graph; just the HTPC direct to the PJ. The key is to keep the contrast down. This way your contrast ratio will be higher, gamma will be closer to 2.2-2.5. Down side is overall brightness is lower. Ideally you need a 100% light controlled room.
I run AGB=ON and have to look real hard to see the AGB line. The AGB line resides at the top of the 4:3 raster and I project wide screen only 16:9 etc. The only time I notice it is when I'm half way through a calibration and the contrast, grayscale and gamma are not set.
Tubes were ~2500-3000hrs. With the lower contrast the tubes are still 8&9s.
No such thing as a stupid question! Well have you got a minute ?
My G70 Contrast's @ 55 at this time but run a little 16x9 92" 1.3gain screen in a Bat cave..
I also run AGB on & rarely notice the line myself , and like my Gamma around 2.35..
I've read A couple good things posted about the HCFR DIY Probe..
