Why does "Black Frame Insertion" f*** up the audio?

Nikorasu081 · 1 Nov 2019, 01:21

I have a Trinitron CRT monitor and i'm running some of my games at 320x240 @120Hz so I can get scanlines. Unfortunately, I have to play with black frame insertion on otherwise the FPS will feel choppy with it off. Only problem with turning on "Black Frame Insertion" is it causes the audio too sound distorted and crackle. Some games are more severe than others. My question is why does "Black Frame Insertion" affect the audio, and can it be fixed? I'm running the latest Retropie and Retroarch on my Raspberry Pi 3B+. It's sad that i'm getting perfect picture quality but the audio just ruins it.

@Nikorasu081 why are you running at 120hz and not 60hz/50hz?

Please refrain from using profanities in the forum - this is an all ages forum and we're trying to keep things this way.

@edmaul69 Because my CRT doesn't do 15khz. It is a VGA PC monitor.

@mitu I censored it though see 👉 f***. Why would you consider it profanity if I didn't spell it out?

@Nikorasu081 You should be old enough to know when to stop testing boundaries.

Offensive language is not welcomed here, some *** don't cover it or make it go away. We all understand the frustration of having something not working, after putting a lot of effort into it, but this is not an excuse to put it into your topic title. Come back in a week if you wish to participate in the forums again - this time having more consideration for the forum rules.
