I want the ability to connect any device to a HDMI screen, whatever ports the device has.
Something like this would be ok: https://www.bhphotovideo.com/c/product/992754-REG/liberty_av_solutions_dl_ar_hdmi_to_mobile_content.html
But more ports, not costing $120 for what can't be more than $25 worth of adapters (at most), and a tidier form factor (like those 500-in-1 card readers that were available before everyone switched to SD) would be even better.
Anyone seen a thing like that?
