Hi Luke,
in the case of fixed LCDs, the only way to guarantee that is to have line (or frame) buffer upscaler ICs *ON THE HOUSING*.
I think there was another discussed solution not requiring "anything" (not even line buffer upscaler IC) on the housing. Namely just drawing the small resolution directly to the higher-resolution display to the edge where the signal starts drawing the first line). Did you abandon it? If yes, then why?
it's NOT as simple as "1920x1080 is supported, period".
Well, in the spec on http://elinux.org/Embedded_Open_Modular_Architecture/EOMA68/Hardware it says for PCMCIAv2 and PCMCIAv3 "maximum RGB/TTL resolution permitted is 1366 x 768" which clearly disallows any negotiation. Could you please correct these statements on the wiki page?
Also, if all the housings must support the rates of 1366x768, then I would say it's too much. One can find devices like small netbooks or tablets or special-purpose devices like projectors, but mainly TVs with resolutions starting at 704x240@60 (704x480@30). For all these mass production will continue for at least the next few years. During these years EOMA HW should spread also to these domains.
doesn't have to be amphenol. any mass-volume connector will do.
MiniPCIe was also something i considered in the past, but finding a right-angle "slotted" connector like the old games consoles proved elusive. and also i was concerned about accuracy of mating, and about having to create a surround shield custom casework.... look at the intel card you'll see what they did. that cost tens of thousands of dollars in tooling costs to make.
Any tips for other 45-70 pins connectors with physical size similar to PCMCIA and being suitable for a possible high-end EOMA spec (maybe utilizing PCI Express link(s) instead of one of the USBs in EOMA68, maybe MIPI DSI instead of RGB/TTL, maybe 18W dissipation like the lowest MXM, etc.)? On http://elinux.org/Embedded_Open_Modular_Architecture there is no such connector. Something like M2 for "big computing" (i.e. made physically robust (incl. full coating) and freed from stuff like ADC pins, 10 GND pins, etc.). What caught my eye is, that M2 actually does not limit thermal dissipation at all.
You tried to contact many manufacturers and companies. Did you happen to contact also M2 creators?
By the way, could you ask administrators of elinux.org to set up either mod_rewrite in Apache (or equivalent in nginx or whatever server they use) or at least disallow/blacklist pages with traling slash in their name?
Currently if one goes to http://elinux.org/Embedded_Open_Modular_Architecture/ , it's empty, but removing the trailing slash gets one to the correct page. This is very confusing (see https://phabricator.wikimedia.org/T14703 and https://bugzilla.mozilla.org/show_bug.cgi?id=961132 ) and therefore e.g. wikipedia is also redirecting to a page without slash (try e.g. https://en.wikipedia.org/wiki/Main_Page/ ).
Kind regards,
