Am I understanding correctly that this is really just a software/firmware matter? So we can just download updates as they become available? Reprogram the VideoAmp via the Windows utility?I am not sure I can answer to this, as the work to be done for on-the-fly reload is mainly on the computer side and as said before, it may have a massive impact on the OS to reload the EDID even if it has only a few modelines.
On Windows 11, it takes a few seconds to reload an EDID with a few videomodes. I can't tell for Linux and MacOS.
On the other hand, once Windows has loaded the modelines, changing resolutions is rather quick.
In any case, being able to plug-and-play with 10-20 programmable video modes is pretty awesome. As you say, a lot cheaper than a GroovyMister setup.It maybe cheaper and easier to use, but be more limited than crt emudriver or the groovymister (I can't tell since I do not own a groovymister).
Regarding the number of videomodes. The board can actually store a lot of modelines, but unfortunatly the OS and the GPU driver may not handle all of them.
On Windows 11 with an RTX2060 for example, I cannot get more than 50 modelines to be read (interlaced resolutions are not accepted).
Depending on your use case, this may be enough. Let's say you plan to play a PS2 emulator and preload an EDID with the needed videomodes for PS2 (maybe 20x including interlaced) that covers all games, then you may load this into the videoamp and perform an EDID reload just before loading the emulator. And if the emulator supports it, you could even dynamically switch between progressive and interlaced video modes in game, in a second.
Something tested in the first post is to prepare a list of 30-50 modelines to cover arcade 15kHz MAME games. Then you load this into the VideoAmp before starting GroovyMAME. Unfortunatly it seems like GroovyMAME/swtichres does not know how to switch dynamically between available monitor resolutions in Windows and pick only the currently used.
I'm looking forward to your next batch coming out, and PM'd you and Bandicoot to put my name on the list already. Please let me know when ready, I want to test with GreenAntz RGB to Component/YPbPr transcoders.Confirm you are on the list for next batch.
Also, there is a very interesting pages that you can read:
