Subject: Having trouble creating my own IO Port Dsub to scart cable
Hiyas, I am trying to make my own cable to work on consumer TVs and I think I am missing something. I dare say my issues are my poor grasp of electrical engineering.
I have a RGC scart to BNC connected to my BVM. If I use my new cable, connected to the RGC cable into the BVM it works. I take this to mean that the R, G, B and csync pins are working correctly.
I have more trouble going into a consumer set. The mister is outputting 3.3v on vga pin 14, which is the scart blanking pin.
- Is scart blanking on pin 16 needed to make rgb work on some consumer sets? I found a spec which says it should be 1 to 3v to show this is csync and not composite video. If I am getting 3.3v on that line instead, maybe the consumer set is not liking it?
- I have a 470ohm resistor on the csync line. As I understood this should be there for consumer tvs. What I dont understand is that the volts I read on my multi-meter down that wire are the same whether I have the resistor on the end or not. Is a resistor on the line supposed to bring down the volts?
- Do consumer sets need scart pin 8 connected? Or is this just for autodetection that AV is present. The spec i read says that this pin should be 9.5 to 12v. Is this the same as if I manually changed the channel to "AV"
Thank you for the help

Good Morning,
I have been tinkering with my MiSTer this morning. I am trying to get it to output at 1080@60hz. However when I edit my MiSTer.ini and reboot I get no video. When I set it back to 720@60hz video is restored.
I have tried this on two LG OLED televisions. I am certain I had 1080p at one point working. I upgraded SD Cards and am having no luck.
Any help would be appreciated!
PS> Any reason not to set hdmi_audio_96k=1 ?
