Beginners • Forcing RPi 4 to output in 720p...

I use a Raspberry Pi 4 with RetroPie, and though I have a 50" 4K TV, the system lags terribly when it outputs at 2160p. After searching for a solution for what seemed like forever, I finally found that adding "hdmi_group=1" and "hdmi_mode=4" to the config.txt makes it output at 720p like I want, but it only does it for the micro HDMI port closest to the power port. The other micro HDMI port still outputs at 2160p.

This isn't really a big deal, as I can always just use the port that outputs in 720p, but it would be nice to not have to always remember to connect it to that particular one.

Is there any way to make it so that both micro HDMI ports output at 720p instead of just the one?

For reference, for those wondering why I'm using 720p, I probably could have used 1080p as the output and it would have been fine, but I only use the Pi4 for NES and SNES games, so 720p is just fine.

Thank you.
