M1 Mac Mini only gives a lower resolution 1280 x 800 dpi or less on a a 30" DVI Apple Cinema HD display.

With my previous mac mini I was able to use an old 30" Apple Cinema HD at high (acceptable and very clear) resolutions using a thunderbolt (1) to DVI adapter. the new M1 Mac Mini did not recognize it when I used a thunderbolt to thunderbolt 3 adapter so I purchased a thunderbolt three to dual port dvi adapter. Now it connects but at really crap resolution with no higher resolution selectable just one other one level worse resolution selectable.
