So out of curiosity, I decided to see what Raspberry Pi was all about and I built one for the wife and I to play a little retro gaming.

Was a fun little exercise and so far has been great except for one issue, HDMI post processing latency.

We are playing on our Samsung TV but I found that the latency was horrible, even when changing the HDMI settings to game mode.

So I enabled the analog video out port on the Raspberry Pi 4 board we have and hooked it up that way and it works great, no latency anymore.

Question I have for the gamers on this board is if anyone knows of a good solution for the HDMI latency so I can switch back to that output, because the analog output makes the Raspian OS GUI almost unusable, just very little screen space, like 1/10 the space of HDMI.

I've done a little research, and it seems the best solution is to get a TV or Monitor with a VGA input and convert the HDMI signal with a cable.

Just thought I'd throw this out since we have a good collection of Geekoids here, maybe someone has a good solution.

If you haven't done this already, I might suggest installing RetroPi. I personally didn't notice any latency with HDMI with this setup .

Failing that, you could get an HDMI "upconverter" like this which might work, but I've never used one myself.

This is a raspberry pi 4 I'm assuming?

I remember reading something related to latency either audio or video for analog on pi4. You probably need a converter, pi3 had a headphone style audio/video jack that worked fine with analog.

I have about 4 pi4's built into various things and no issues on any of them through hdmi converters or right into an hdmi input on standard settings. Audio doesn't work on my receiver without a changing some setting but there's plenty of info online to fix that.
