Screen Tearing?

[Weasel497]

I'm building my first GBZ right now and and I'm having issues with what I can only describe as screen tearing. Every time I play a scrolling game, like Mario or Pokemon, when the background scrolls, it seems like parts of it are moving faster than others and it's very distracting and gives me a headache. I'm using the KeDei screen, but I've had similar results with HDMI out to my PC monitor, and also with a composite BW screen. Also, audio over HDMI is very choppy and laggy and doesn't sound even close to what it should. Are there settings I'm missing, or is this just something I have to deal with?

I noticed the screen tearing on my hdmi GBZ build too using the keidei lcd. Resolution is great but it lags and tears. That is why i like the DPI much better. It's pixel perfect, smooth and fast.

I notice it on my BW composite screen too, but not quite as bad. I just can't get the quality from that screen though. Can't read any text, it just looks awful.

Yeah. Composite is fast but display quality iis not that good. HDMI has better resolution but lags and tears. DPI is both fast and clear.

I wanted to use a Kedei screen, but the screen tearing was too much to bear. The final straw was its immense heat output. DPI is truly the best option IMO.

Immense heat output sounds the HDMI controller is quite buisy. Maybe you do not run retropie in the Kedei native resolution? Check your config.txt for this setting using the Kedei screen:
hdmi_group=2
hdmi_mode=87
hdmi_cvt 480 320 60 6 0 0 0
