Request: correct video positon according to real HW. #33

Closed lencio closed 2 years ago

lencio commented 2 years ago

I have a problem with the position of the image on the screen of the ZX-Spectrum core in several CRT televisions (15hz), using VGA / SCART. Basically the problem is that on some TVs, the core is off-center to the left, even losing the entire edge. On other TVs, the core is off-center to the right, or above the screen, losing the upper edge depending on the model. It is an issue that I have reported in Main_MiSTer and I have been answered (thank you) that it is better to post the problem in each core individually, since it is not possible to implement it at the framework level. It would be great to have a Horizontal / Vertical position control in the OSD to be able to center the image regardless of the TV used. I have tested the real machine on different TVs and curiously the image does come out perfectly centered. I have tried several SONY trinitrons as well, such as SAMSUNG and SANYO models.

If i remember right, it fully matches original HW.

I open these issues, because the image is not centered on several different CRTs, not because it is fun for me. My idea with this is to make each core better, not to make anyone work without meaning. That adjustment is necessary. Thanks once again for answering me.
