Raspberry Pi Zero Retropie no HDMI on Samsung TV



  • Man thats weird....I have a 65 inch samsung downstairs and the pi seems to work fine with no setting changes.
    Tough one.



  • Boost is at 7 atm. The RPi sees the TV, I can see that when I run tvservice -n

    I can provide this. I so not know how to provide what you are asking.

    @jnbui79 http://commonmark.org/help/ (as linked at the top right of the edit box when writing a reply)

    config looks fine - I wanted to check hdmi_safe=1 was disabled as it overrides the other settings.

    Is the HDMI cable long ? If so you may need to increase it further (eg to 9), but I would first try with another cable, in case it's cable related (even though it works with other screens, there could be an issue).



  • I've tried with about 6 other HDMI cables so far. The current one that I am using is 1 meter. Yea I am at a lost myself. I'm going to go pick up a couple other RPi's today and some other HDMI's and adapters and see if I can get this figured out. Maybe time for a new TV? I've been looking for an excuse but it'd be frustrating to let this RPi beat me. I'll keep this updated with my findings.

    Thanks everyone for the assistance

    @jnbui79 You should open a thread on the official Raspberry Pi forums - https://www.raspberrypi.org/ and you may get some more help. They may be able to help you debug it further (some of the devs are there).



  • Wil do, thanks



  • I'm a complete newbie to using RP and having a similar issue with my Samsung TV. In my case it reads "Mode Not Supported" whenever I plug the RP Retropie into it, but it works perfectly on my son's television. I've played with the settings on the samsung, but to no avail. I suppose I must delve into the coding on the pi, which will be a new experience for me as this little project was my first go at it OR I must get a converter box to turn HDMI into RC for use with that TV. I've heard converters make the picture pretty sketchy. Not sure what t
    o to do here!



  • @jnbui79 Any update? I am having this identical issue on my Samsung set. RetroPie works perfectly on every other TV I try it on.....

    Please let me know. Thanks!
