Just installed an Indy LCD at the museum. DotsXL all the way on this one.
Dots is OK.
Scan and Hi-res look too “goopy”. Probably most others will from this era too, as the design process assumed DMD would be the output format (much like scanlines on classic video games - in a similar way I use scanline generators on LED panels to make them look more authentic).
Pixel is good for scores, bleh for everything else.
Worst is 8-Bit. Goopy AND blocky. Yuk.
