If you have another computer to use, transfer the file to it and try uploading from that one.
If you are using RS-232 for remote control (e.g., Crestron), be sure to reset the RS-232 stuff in Setup back to the normal defaults before using Anthem's PC applications. See the picture of that menu in the Manual.
ALSO, there are very few people posting here on their experiences using the Custom Gamma Correction stuff available in Live Video Settings Editor. In fact the last person who wrote this up was, I believe, using a D2! So it would be helpful to others if you could write up what you did and what you learned. Tricks like the conversion factor you just mentioned for example.
With pleasure! If i can contribute to this forum for once instead of leeching I'll gladly do it.
Actually it is simpler than i thought. The only glitch as i described it is a very hectic connection through RS-232. I am using a USB-to-COM adapter though but who doesn't nowadays, since all the COM ports have disappeared from laptops? So for the connection i will check with Anthem.
About what it does...
You can build 2 different custom Gamma curves, apart from the more standard exponent ones.
The custom 1 has an effect on the known exponential curve, so you can add or lower luminance at certain points (IRE). Now the graph is not graduated in IREs for some reason that I will have to ask but in fact they match, I mean 50IRE is around the 500 on the graph.
The tool is pretty clumsy so it trial and error but on the other hand it is very effective and the result was very impressive.
My projector is an Epson 9500UB and when using a high light output preset the Gamma is pretty distorted. And my proj settings were off limits.
Thanks to the d2v I managed to get an almost flat response at 2.4 which is what i needed.
The custom 2 is much more extensive since it has an effect on the RGB or Grayscale balance. Note that you can use either Custom 1 or 2 for each output, not both.
The principle is the same. Each color has its curve and you can fine tune the correction to incredible lengths.
If only the tool was more "mature" that would unleash incredible possibilities.
For example my proj has flaws inherent to its place on the market. It has good performances if you don't push it too much. But if like me you need more light or better contrast then you start to see its limits. For every important setting in a calibration you might be off limits. This is where a powerful video processor can help.
I hope this helped. I will keep on inquiring about this tool i think.
