  • VGA/DVI or HDMI?

    I see that the new Lilliput have both HDMI and VGA/DVI connector. Which is the best way to connect to the computer? Since now most modern graphic card and motherboard have a HDMI output port.

    Thanks

    it's really a matter of preference. Quality on both is at least good enough. If it's more convenient to go hdmi/dvi, I'd go that route.

      VGA is analog which means colors are drawn across each raster at a specific speed which may not line up with an LCD pixel exactly.

      HDMI is basically the same as single channel DVI and HDMI 1.3 is capable of using the full colorspace like DVI. They are digital which means every pixel goes where it's supposed to and is the color it's supposed to be.

        Here are the specs for the Lilliput 669GL-70NP/C/T-5HB which I am planning to use:


        Key Features:
        Video system: PAL/NTSC
        2 Video inputs plus 1 Audio input, input signal: composite video
        1 VGA input (15-pin D-sub), Input signal: Analog VGA signal
        1 HDMI or DVI input
        5 wire resistive Touch screen, USB interface
        IR remote control
        Full function OSD control (Multi-language)
        Audio output: Speaker built-in
        Wire for auto switching to backup camera

        Included Accessories:
        AC adapter
        Car 12V adapter
        Stand
        VGA / USB 2-in-1cable (VGA for PC signal and USB for touch screen monitor control)
        HDMI Cable,
        HDMI to DVI adapter
        A/V cable (RCA)
        Remote control with battery
        User's Manual
        Installation CD (driver and software for touch screen)

        So in this case I would use the HDMI port coming from the screen and just use the included adapter to connect to my graphic card on the DVI port?

        Or I can use this cable to connect from the HDMI port on the screen directly to the DVI port on the graphic card and won't need the adapter:

          you wont be disappointed with the screen i've got one i'm testing now. Its great! HDMI/DVI allows for less noise to be picked up in the cables and gets rid of the ghosting that ALL of my lilliputs seem to have had at some point. My review for the screen will be on the homepage tomorrow if you want to check it out.

            I think I understand now. So this cable is included, all you have to do is buy an extension DVI cable and connect to your computer. Do you also have to connect the USB cable to get the touch functionality if you use the HDMI to DVI?

                Yes you still need to hook the USB cable up

                    We don't really have one planned for October yet. I better get on that I guess cause it'll probably end up being the last one of the year

                      as has already been stated, i agree.

                      in a mobile environment, i think that dvi has more advantages then hdmi, but that is partially personal preferance(i have grown to hate hdmi-- every time i use it, i am trying to make 2-3 devices play nice, and they rarely do..)

                      dvi has the set-screw connections(or whatever you call it), so it will fare better with the vibrations in a car(i have seen some variations of hdmi with set-screws, but i don't think they are prevalent enough to consistently recommend), also it does not support audio, so it is one less thing you need to mess with to get everything working(i don't think i know of any carpc's that use the lcd-display speaker for audio)

                        Yeah, this screen does not have a DVI port, it is a HDMI-->DVI. Now, is it truly DVI, I am not sure

                          Its not truly DVI, the back of the screen has a female HDMI port. The sources for HDMI and DVI on the unit are shared (setting the screen to DVI or HDMI will display the same thing regardless of which cable you use). The HDMI connection is VERY tight though. You definitely dont have to worry about it coming loose over time. I've nicked up my hands quite a few times trying to pull the darn plug out in small spaces.
