MiSTer @ 1440P 4:3 stream+capture with output to LG C1 OLED

[Mellified]

I stayed up way too late last night, but I got my setup re-wired and re-configured so I can capture and stream MiSTer @ 1440P 4:3 while outputting to my LG C1 OLED! I had to move my other devices onto a USB capture card and put the MiSTer directly into the PCI capture card. Most of the time was diagnosing a bad HDMI cable and figuring out how to get SLOBS to use 4:3 correctly.

1440P 4:3 is the maximum the MiSTer can output. It allows a 6x integer scale of most retro game resolutions. I had a hard time finding information about this setup so I thought I should document what I did to help anyone else going down this road. The gear I'm using:
- C1 LG OLED
- AverMedia Live Gamer 4K (GC573)
- MiSTer

Setup notes:
- My PC is set to 3840x2160 (4K) at 120Hz, directly connected to the LG TV and set to "PC" input label
- SLOBS Settings -> Video -> Base (Canvas) Resolution: 3840x2880
- SLOBS Settings -> Video -> Output (Scaled) Resolution: 1920x1440
- MiSTer HDMI out to AverMedia capture card HDMI In
- AverMedia capture card HDMI Out to LGTV HDMI In (optional)

which avermedia card u using my live gamer ultra don't like 2048 by 1536 but might try the res you used. Has usually stream at 1080P. ps 2048 by 1536 works on my lg oled tv but no so lucky with streaming card. can be done has it does 4k streaming but streaming card requires firmware update to capture it.

As stated in the original post: AverMedia Live Gamer 4K (GC573). It’s a PCIe card - and one of the very few I have found that accepts 1440P resolutions.

Does the C1 support a 4:3 1440p signal?
