      @leoxmasa said in Problem with my 4k TV:

      hdmi_group=1
      hdmi_mode=16

      Try adding this to your config.txt and reboot

      hdmi_max_pixel_freq:0=200000000
      hdmi_max_pixel_freq:1=200000000
      

      No black screen but still in 4k 30 fps (with group 1 mode 16) and the line you told me to add

      pi@retropie:~ $ tvservice -s
      state 0xa [HDMI CUSTOM RGB lim 16:9], 3840x2160 @ 30.00Hz, progressive
      

      edit: I have black border arround screen now ans i still have low fps

            I guess you can tell the Pi to ignore the EDID info from the TV. Add these lines (make sure they're not commented):

            hdmi_ignore_edid=0xa5000080
            hdmi_group=1
            hdmi_mode=16

                That't strange. Are you using the image from retropie.org.uk/download ?

                  for my install:

                  • I used raspery pi imager (to download the last version)

                  • I'm booting on SSD USB

                  • I've installed safe shutdown script for my nespi case

                  Actually in my hardware installation i have the R4 connected to my denon amp, connected to my tv. (it work for all my other devices (ps5 switch et PC)

                    I have found a way. I # everything, connecte my raspberry to a no-4k port of my amp audio , and now it show

                    state 0xa [HDMI CUSTOM RGB lim 16:9], 1920x1080 @ 50.00Hz, progressive
                    

                    It's seems retropie doesn't like my Audio Amp.

                    i there anyway to remove the border aound ? :)

                      @leoxmasa Yes, add disable_overscan=1 to config.txt - see https://retropie.org.uk/docs/Overscan/.
