      I checked the config.txt file and it is set to 720p (1280x720) but my projector stays at 578p (720x578) at boot and in ES

      But when i start kodi from ES my projector does go to 720p....
      In fact, when i start my emulators it also changes to 720p.

      What am i missing here??

        @G-Member Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first - You have also been asked this before - we cannot guess your configuration.

        in this case providing your /boot/config.txt would also be useful - Please put it in a codeblock -http://commonmark.org/help/ - or use an external pastebin site.

          Whats your deal, my english isn't that good so give me some slack.
          I'm reading lots of simular topics and they get answers without reffering to every rule in the read-me-first-post

          Why providing the config.txt file? it's virgin from the retropie image.....

            @G-Member I'm sure you can manage to provide some details from that post - it's not about giving you slack or not - it's about us having the information we need to advise.

            The /boot/config.txt isn't set to 720p by default, so that's why I need to see it - to advise what you need to change.

            If you want people to help you, I suggest you try a different approach.

              I'm sorry, i didn't mean to be rude ,i'm a bit frustrated not understanding everything what is mentioned in the read me first post....

              Here's the copy/past from the config.txt and i did nothing to it yet......this is from a the original untouched image from the official page.

              # For more options and information see
              # http://www.raspberrypi.org/documentation/configuration/config-txt.md
              # Some settings may impact device functionality. See link above for details
              
              # uncomment if you get no picture on HDMI for a default "safe" mode
              #hdmi_safe=1
              
              # uncomment this if your display has a black border of unused pixels visible
              # and your display can output without overscan
              #disable_overscan=1
              
              # uncomment the following to adjust overscan. Use positive numbers if console
              # goes off screen, and negative if there is too much border
              #overscan_left=16
              #overscan_right=16
              #overscan_top=16
              #overscan_bottom=16
              
              # uncomment to force a console size. By default it will be display's size minus
              # overscan.
              #framebuffer_width=1280
              #framebuffer_height=720
              
              # uncomment if hdmi display is not detected and composite is being output
              #hdmi_force_hotplug=1
              
              # uncomment to force a specific HDMI mode (this will force VGA)
              #hdmi_group=1
              #hdmi_mode=1
              
              # uncomment to force a HDMI mode rather than DVI. This can make audio work in
              # DMT (computer monitor) modes
              #hdmi_drive=2
              
              # uncomment to increase signal to HDMI, if you have interference, blanking, or
              # no display
              #config_hdmi_boost=4
              
              # uncomment for composite PAL
              #sdtv_mode=2
              
              #uncomment to overclock the arm. 700 MHz is the default.
              #arm_freq=800
              

              Grtz,

                    Do i need to remove the # for this?

                    uncomment to force a console size. By default it will be display's size minus
                    overscan.
                    #framebuffer_width=1280
                    #framebuffer_height=720

                    I read this in another forum, uncomment = remove the # for changes take effect.

                    Could this be what i'm missing?

                    EDIT: guas not, after removing the # and rebooting still the same only filemanager gets cropped

                      I changed this last night on my Raspbery Pi Zero and it went to 720P mode. Change:

                      #hdmi_mode=1

                      to:

                      hdmi_mode=4

                      Save, then reboot.

                      There's a chart HERE which has the different HDMI_MODE's.

                            @Dochartaigh Not as criticism, but as an advice: Whence providing a hdmi_mode, good practice is to also provide hdmi_group (especially if hdmi_force_hotplug is also set (so there's no need in switching on the display first, ie. good for headless starts for accessing the pi via ssh and if one may decide to switch the display on later)), as mode 4 for group 1 (CEA) is 720p 60Hz, but for group 2 (DMT) it would be 640x480 60Hz [And I know of at least one Samsung(?) TV that is offering both CEA and DMT Modes] [Edit: And maybe with a pi4 the hdmi port it is meant for].

                              As this thread was approaching 6 years old before you replied, it is best to open a new thread and fill out the information requested in https://retropie.org.uk/forum/topic/3/read-this-first

                              Then you can get specific help for your issue.

                              EDIT: And the user to whom you replied also hasn't been online since they posted that comment.

                                @YFZdude Yikes - That one sliped my awareness....

                                @mitu I am not sure whether it was here or another forum, but I know that some fora warn the user whence replying to older topics. Is it possible to activate such a function here (please ignore if this forum actually is already warning the user about it) ?

                                  @Ashpool Yeah, the forum already warns when replying to an old topic.

                                    @Ashpool said in Can't get retropie 4.1 to boot in 720p:

                                    . Is it possible to activate such a function here (please ignore if this forum actually is already warning the user about it) ?

                                    It is activated, but the warning was probably shown to @RickyTan, your reply was later.
