  • 7 inch transflective with HDMI or DVI

    Hello.I've been looking to get a optically bonded transflective screen because i cracked the touchscreen on my cheap Onvon 7 inch and also tired of not being able to read what's on the screen during daytime driving.Is there one that has a HDMI or DVI interface though?I want this because on my Onvon 7 inch(before it got damaged),I get a lot of interference on screen.You know,those lines that keep running from top to bottom.I heard that running a long VGA cable produces this.I have the monitor cable connected to a female to female adapter then another 6 feet of VGA cable onto the carpc video card which is in the trunk.Maybe bad grounding also?I'm just afraid that after spending $600+ that i would still have this issue with all the optically transflective screens out there being VGA only.Or is there a way to swap the interface to HDMI or DVI?

    I'd like to see one, but so far, not yet. There are DVI-I/HDMI to analog vga converters ($78.00 at Amazon), but they're not easy to hide, need power and it's another expense.

      Rippling, you wouldn't just do an HDMI to DVI then DVI to VGA converter?

      Not exactly the cleanest, but wouldn't that work?

        I think I got it wrong. Computers generally have a DVI-D output, not DVI-I. DVI-D is all digital, DVI-I to VGA just needs a cheap adapter.

        The converter I posted would work with computers. Now I don't know any DVI-D to VGA converters, what unit do you have in mind?

          Anyone running a long VGA cable from dash to trunk getting the interference just like me?I really would like to get away from adapters and just have a nice straight through connection.

            i have used these in the past on large commercial jobs, and they work great(never really had a problem with interferance-- and the cat5 is run near electrical lines), though at $190 a pair, ain't cheap:

              I did use a 6ft+5m VGA extension in my M35 (trunk to dash), very cheap extension I bought at my local Fry's. Never had any interference. I did have some interference in my desk, though, with 6ft cables (too close to power wires).

              I would check the connectors, and try another cable. Also try to see if the interference does not come from the computer case itself: can you turn the computer and monitor with the car completely off (bring a modded ATX PSU to test it)? If you still get interference, then maybe it's not the car generating interference.

                I have a DVI-I-to-VGA adapter on my MB in the trunk then run to the screen in the front. Any time I used a cable longer than 12ft i would get ghosting and such on my screen. I went out and spent lots of wasted money on high end VGA cables that were triple shielded, gold plated etc... I then bought a signal amplifier (good up to 150ft) and that left me with the same results as before... (any cable more than 12ft had issues). After testing I found that if I made the long run from the trunk to the front of the car THEN put the signal amp near the screen and ran a short cable to the screen it fixed the problem, so that is how I have it. Unfortunately I probably spend more money doing it this way than if I just ran it digital and converted it to analog at the screen, plus on top of that I had to make room for a fatter VGA cable - a thinner digital cable would have been easier to run.

                  I used this:



                  To extend the cables to relocate the OEM 7" screen on the M35, from the dash to the center console (about 10-12ft). No ghosting at all. The carPC was in the trunk and the Xenarc on the dash, I run the long VGA cable through the middle of the car, under the center console, etc. Too many wiring going on the sides by the door sills (harnesses and my own 4 gauge wire with 12v to the Carpc), including my power cable, maybe that explains why I could get away with it.

                    I really wish the companies would hurry up and make this kind of monitor so i can buy one.LED backlight,HDMI/DVI,optically bonded transflective and AR coated.Better yet,have the option of getting capacitive touchscreen while they're at it.I miss having a carputer on my car

                        Thanks for looking out.I just sent them a message asking if it is indeed optically bonded because it doesn't say anything about that on the description.Hopefully it is so i can get it .

                          Sadly,Model MHD700-SH transflective pro with DVI from cartft.com is not optically bonded. I might just get the mo-co-so lilliput optically bonded transflective with VGA if and when i resolve my interference issue with my current monitor.

                              Lilliput offers sunlight readable as an option if you order from them. When I priced a 7" version it was about $450.00. Their HDMI version would probably be a little bit more.
