QUOTE(anfieldude @ May 9 2011, 12:16 AM) Kiding, U r seeing clipping in the high IREs. Its typical if u r running contrast too high. Pls try reducing contrast until the gamma at the 90% stops clipping. Pls send me the HCFR files and I will take a look as well. Okay, thanks for the suggestion, I will try to correct tonight. Below is the HCFR files, please have a look.

QUOTE(anfieldude @ May 9 2011, 02:43 PM) Will spend some time later to review the data. There are various gamma options on the Optoma. I believe Cinema was almost 2.5 and PC was close to 2.2 the last time I calibrated one. Reducing contrast shd elimnate the clipping. After lower my contrast and change the gamma curve type to 1, the gamma chart is better now, but at above 70% grey, the value is now shoot up  Luminance chart also get improved, only the RGB has slightly higher delta value. take another one and half hours to calibrate  Will further calibrate the RGB next time when free. Anyway, thanks for the advice. below charts are the result of second calibration Gamma Chart Luminance Chart

QUOTE(anfieldude @ May 10 2011, 06:00 PM) Looks much better now. U might be able to push up contrast 1 notch though. Do post ur HCFR files as well. Did u do the gamut? While it does not have a CMS, u still need to set colour and tint correctly. This will effect gresycale sometimes if u hv to make big changes. Let me know if u need assistance. The HCFG file is attached as after2.zip, you may download it. I didn't run the advanced color management, too tired to do it, my SVS sub will come in this weekend  and then need to run the REW too probably will do it when have more free time. |

QUOTE(jchong @ Sep 12 2011, 05:15 PM) That package is ok. Only issue is for projector use, it's not easy to mount the i1 meter - no problem if you use the meter for TV. Need to get some kind of tripod mounted clamp. I use masking tape to mount i1display to Manfrotto tripod head, easy and simple  |
