Monitor presets
Edglaf:
I've been using for a while for various televisions. They make, up to date, the most sensible replacement for an old-style arcade cabinet. However, it is frustrating adjusting the image geometry because we do not have potencimetres at the back of the chasis to perform this task with just two fingers.
Instead we have the service mode. Normally it can easely be accessed, sometimes it can not for whatever reason. Other times, specially in chip brands, it offers anyway severe limitations making it useless for our purposes
Among the commonest problems spotted using generic_15 and default crt_range0 values:
Overscanning of the vertical size
horizontal shifting etc
By trial and error I guess I could eventually get a decent adjustment but I do not understand well how this format works, and how these values interact one each other. I simply get the idea that modifying "porch" values change dramaticly the geometry features we interest. How can exactly these values correspond to TV service mode geometry aspects feature?
namely:
V-size
H-size
v-shift
h-shift
thanks,
Calamity:
V-size: not adjustable by software.
V-shift: proportion between V front and back porches.
H-size: inversely proportional to the sum of H front and back porches.
H-shift: proportion between H front and back porches.

Calamity? What do you think about my settings in my previous post? ;-)

Hello all,
im new to this CRT_Emudriver witchery and asking myself if anyone has good presets for my Phillips 28PT7007/12 Consumer-CRT. My problem is that with the Arcade-15khz setting my picture in SNES games is too far to the right and bottom. I have to move it to the left (like maybe 1-1.5cm) and up (maybe 2-2.5cm) to be centered.
Any suggestions are very welcome. Maybe someone had a similar problem.

Well, guess this was a longshot to begin with, lol. But maybe someone is kind enough to give me some information about the "monitor_specs" line. I have a RGB-Scart CRT, so i can output 50 and 60hz but im not sure what resolutions i can output. Is it enough to put PAL resolutions in the line or do i also need a line for NTSC resolutions?
Second Question: Can i adjust the porch values like i did in the HDMI timings of my Retropie/Pi2Scart System to center the image? The dimensions are different here somehow (VPorch Value <1??).
Thanks in advance.
