      @fulton1 Can you send me some info about your screen and the controller board that drives it? Manufacture name and any and all numbers on the back. Maybe take pictures of it and post them here. I have some limited experience with this type of screen.

          @fulton1 OK.. This is only a guess but you could try to change the following lines:

          "disable_overscan=1" should be commented out

          "#hdmi_force_hotplug=1" should be uncommented out

          The line: "force 800x480 resolution as this is non-standard for HDMI" should be commented out

          "hdmi_mode=1" should be commented out as it is in conflict with the next line "hdmi_mode=87"(this line should be OK)

          That's all I can come up with for now. Give this a try. Good luck :-)

            no change whatsoever, my config.txt now looks like ;

            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

            hdmi_mode=87
            hdmi_cvt 800 480 60 6 0 0 0

            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=1000

            Uncomment some or all of these to enable the optional hardware interfaces

                Your boot text is cut off also. Look at the second line of text. Can you post a link to an eBay or Amazon listing for the screen you bought?

                    I have a similar screen with identical resolution. Here is the entirety of my /boot/config.txt file which works for me.

                    # For more options and information see

                    # and your display can output without overscan

                    disable_splash=1
                    

                    The important part is here:

                    # uncomment to force a specific HDMI mode (this will force VGA)
                    #hdmi_group=1
                    #hdmi_mode=1
                    hdmi_group=2
                    hdmi_mode=1
                    hdmi_mode=87
                    hdmi_cvt 1024 600 60 6 0 0 0
                    

                    Not sure why but yours is configured for 800x480.

                    Hope this helps!

                      @Douggernaut Didnt make a difference bro, if anything it moved it further to the right, ive lost 2 days to this damn screen :/ BUT the text at the start is no longer cut off!!!!!

                      EDIT:

                      it is cut off, i thought it hadnt because the font size shrunk

                            @fulton1 OK.. I found a link to the manual for this controller card but I don't think this will help. "http://www.elecrealm.com/down/html/?40.html" It looks like the only way you can change the resolution of the screen is to use a PC with a parallel port and a cable. No luck :-(

                              @glennlake So nothing can be done ? :(

                              i did have another screen in this card before and it was PERFECT ( i broke the screen by forcing it into its place :(

                              So it might be the screen?

                                @fulton1 he night be able to force a custom res to whatever the board is set too. You can do custom modes on the rpi to a degree. Maybe an edid dump would help

                                        @fulton1 I'm on phone, so can't link. But search for raspberry pi edid dump and you will find how to do it.

                                            @fulton1 welcome to Linux my friend ;) you're either neurotic like me and will spend weeks on a seemingly simple problem and be ecstatic when you finally figure it out or you'll just buy something known to be supported in the first place and save yourself the headache ;)

                                            I find the problem solving to be rewarding as that's what the pi is all about but sometimes it can understandably be frustrating
