Now it looks much better. I'm still not able to get EDID information (will look into that), but manually enabling HDMI output seems to work and I can see such output on console: dvisampler0: ph: 8 13 5 // charsync:111 [4 4 4] // WER: 0 0 0 // chansync:1 // res:1024x768 dvisampler0: ph: 9 14 6 // charsync:111 [4 4 4] // WER: 0 0 0 // chansync:1 // res:1024x768 dvisampler0: ph: 8 13 7 // charsync:111 [4 4 4] // WER: 0 0 0 // chansync:1 // res:1024x768 dvisampler0: ph: 7 14 6 // charsync:111 [4 4 4] // WER: 0 0 0 // chansync:1 // res:1024x768
I'll continue testing tomorrow.
