Hi Calamity, thanks!
This problem has probably been introduced by the -pixel_precision option. Probably turning it off will fix it.
My thought is that I would prefer the most optimal settings to preserve the monitor, so if the preset settings of PSTAR isn't working properly because of the -pixel_precision option, I may think to disable the option, keeping optimal preset of my polo star. On the other side, if to change that value is safe for the monitor I would change the value to find a stable synced picture keeping active the -pixel_precision option.
So for me the question is: to modify such values is safe for the monitor?
The other thing in which I'm still not sure is:
I followed your suggestion changing from 0.400 to 1.000 like this:
crt_range0 15700-15800, 50-65, 1.800,
1.000, 7.400, 0.064, 0.160, 1.056, 0, 0, 192, 256, 0, 0
then if 1.000 is still not enough you suggested to increase of 1.000 to the maximum of 4.700 I expect i have got a margin of 3 steps of 1.000 before to reach the upper reasonable limit. ( 2.000 , 3.000 , 4.000 )I got it right?
Doing steps of 0.500 I have some more step in between to try ( 1.500 , 2.000 , 2.500 , 3.000 , 3.500 , 4.000 , 4.500 ) Correct?
Sorry to be so pedantic, I have just the fear to do something not healthy for the monitor!
Thank you very much
