Hello everybody. I have an Epson 5030 with 150hs of use.
I have read this topic several times and can not adjust the gamma of my projector.
Even without any calibration adjustment the result of Gamma is a very big drop from 60 IRE. And then, really lowering the contrast, does not solve the problem. To get an idea of the situation, I came to put the contrast in -20 and does not solve. I also used the chart for adjustment of gamma. Completely downloaded the second and third from right together with this low contrast.It made no difference in the Gamma and the image was too dark, lifeless and ugly.
Each time you calibrate the projector to achieve the target Y the result shows that always need to download the contrast more. Always a 2 points from the IRE 60. I can never achieve the right result because it always asks the same two points less.
I could not adjust the contrast in order to see the bars 233 and 234 not putting in maximum or minimum.
My colorimeter is 7.8 inches away from the screen. Use a HTPC Zotac Nano. I'm running AVSHD from it. My screen is 0.8 gain. I've been using CINEMA mode.
A detail: I could only see the bars 234 and adjust the contrast, by setting the KODI to (0-235) and leaving the Epson normal HDMI. It does not solve set the Epson to Expand HDMI and let the KODI in normal mode.
At the address below I found a picture on the internet that shows a graph of gamma almost the same as my case:
Please, any tips of where I am going wrong?
