      Are you using the composite? Even though it's a tft, it isn't set up the same way as a hdmi display. You'll most likely need the settings for a CRT configuration. 480p would be the resolution needed and most likely 50 or 60hz.

          you'll need to change the config.txt file.

          sdtv_mode=2
          sdtv_aspect=1
          sdtv_disable_colourburst=0
          framebuffer_width=640
          framebuffer_height=480
          overscan_left=27
          overscan_right=0
          overscan_top=0
          overscan_bottom=0

          I'm not 100% on these, so someone might need to check this out and I'm not sure if that's all you need.

              @ballboff Thank you very much for that, because my screen text looks a little bit nicer and easier to read, THO i have a new problem I may need to enable overscan and the screen is flikkering a little bit (maybe it's the screens fault) And the last thing the words and the screen has a litttle bit of flikering [maybe framerate problem] does anyone know about how to fix screen flickering?

                I'd just check the specs of your screen. That refresh rate might not be correct, I made an assumption that 60hz would work ok, as it does with most screens. Yours might be different.

                  @ballboff My screen box says that the resolution is 640x480 but it does not say at what hz it is can I change hz thru the config file?

                    not directly, but where it says stv mode, you have to change that to correspond with the display mode you want. e.g. I think mode 1 is VGA, which is the same as 640x480. I don't know what the difference is between that and vga other than that's probably 50hz or lower, so you could try that.

                      @ballboff I got that done, but the text still flickers a little bit and also the lines flicker.

                        If you still have trouble, you maybe interested into an adapter that converts hdmi to vga. This is the way I set up my 640x480p vga monitor.

                          Don't know then. There may be some other setting that I'm missing, but you shouldn't need an adapter. The composite is designed for this purpose and you'd think the standard resolution would be suitable.
