Strange spots/static on display and sound - pi zero

[hayesg316]

Hi all

I Love this app... So much fun... I have one issue though. There is a weird speckle or static on the screen, and the audio is staticy (so?) as well. I don't think it is a hardware issue, as it works and looks fine from a command line. I can try (as soon as I get another Microsd card) to put a different OS on the pi zero to test. Here is a screenshot (well, my phone camera picture).

Any ideas?

@hayesg316 are you overclocking? Have you tried a different hdmi cable?

[hayesg316]

@edmaul69 yes, I've tried a different HDMI cable, and no on overclock. Like I said, if I drop to any of the RetroPie command line config screens, it looks perfect... It's only in games or in the RetroPie menus

@hayesg316 can look into the hdmi signal boost setting (http://elinux.org/RPiconfig), but it could be a hardware issue too - you may have a faulty rpi.

I had that EXACT problem from a Pi Zero. Turns out i was using a cheapo chinese mini hdmi to full sized hdmi adapter. I tested the same cable on a second pi zero and had the same issue.

When i switched to a quality cable it fixed that exact issue. Are you using a cheapo no-name hdmi cable?

@Capeman I'm just using one from Amazon basics... Think this would be better? BlueRigger High Speed Micro HDMI to HDMI cable with Ethernet (6 Feet) https://www.amazon.com/dp/B0060AU5MW/ref=cm_sw_r_cp_apa_msCRybPQ9M5Q2

Not sure, but usually you get what you pay for with electronic components. Might want to get one of the specific ones for pi zero from a more specialized distributor like pimoroni or element14.

So, I purchased a mini HDMI to a standard HDMI cable, and replaced the cable and adapter I had (the amazon basics mini HDMI to female full size HDMI adapter). Everything works perfect now. Thanks everyone!!
