Monitor presets
Torkyo:
Hi Calamity, thanks!

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
Calamity:
The -pixel_precision option is just calculating the preset more accurately, so now you really get 0.4, instead of a rounded-up value. So the "official" preset is wrong, the -pixel_precision option is just exposing the issue that was masked before.
Changing the sync width is perfectly safe. As I said 4.7 is the standard. Just use a value that works for you within that range. Keep in mind that increasing the sync pulse more than necessary will push the picture to the right, so you might need to compensate later with the monitor controls.
Your Polostar will break eventually, not for this or the other preset but because its chassis is poorly designed.
Torkyo:
Thanks you very much for your detailed explanation! very much appreciated, now I got it! and I'm gonna test the best value.

Don't tell me! I sent the chassis to the fixer 3 times already! but wisely I got a polo star chassis back up as well!
thank you very much again
