All 24 modes the sink advertises set with modetest, from 1920x1080@60 down to 640x480, including the mixed sync polarity modes 1680x1050@59.88, 1280x800@59.91 and 720x400@70.08, with nothing in dmesg. One thing outside this series: the modetest pattern showed small black bars until I wrote 200 MB of other data, which pushed the pattern out of the CPU cache into memory, after which it was clean. The U74 has no Svpbmt, so the dumb buffer mapping stays cached here. My v5 run had the SiFive uncached-alias errata patches applied and did not show it. Tested-by: Owen O'Hehir
