    Roof mount monitor?

    Looking to put in a large (13-17" 16:9), roof mount monitor (non-touch) for a PC that will just act as rear seat entertainment system for the kids and occasionally me and the wife.

    This will be for a Honda odyssey so I shouldn't have an issue fitting the large screen in there.

    I figure I should go for one with a VGA or component input but I'm not finding many of those.

    I found the Xenarc 15" which seems nice but I don't see anyone else using it:

    Are there any other good options in a flip down housing out there? Should I just go with a cheaper, composite display since it will only be for video and selecting audio tracks?

    You have any skills with woodworking, fiberglass, etc.? If so, buy yourself a 15-17" lcd monitor (computer) from ebay really cheap, and build your own flip down mount/housing for it. You can get a decent 15" lcd for under $100 these days. I found some with light scratches (not noticeable really) for $49.99 actually. I'm actually considering the same thing for my Odyssey. Although I have a 13" flipdown by NITRO sitting here that just needs a replacement cable that I may or may not end up using.

    Is this place legit? They list contrast specs as "brightness" most of the time.

    I have the 15" version of this monitor, but be careful because the non VGA and VGA come in the same box. I got the non VGA version and had to go through a almost 3 month ordeal with good deals to have the issue fixed. They stated they didnt have anymore of the VGA versions, but it turns out the non VGA version is the same thing, just missing the VGA cable and port. The header is built on the Controller. So Good Deals sent me the cable and I converted it to VGA. Also as a note this screen does not run on a high refresh rate like most screens. Most run at 60, but this one runs at 50. Thankfully my graphics card has multiple options to have 2 diffrent refresh rates running. If this will be the only screen then your ok. i have 3 other screens and they all have to run at 60. Also to mount this is a mission.... You cannot weld the special roof plate to the roof with welding or you will warp the roof. You have to use a metal epoxy. I took mine to a welder and they gave me this special aircraft epoxy which is very smelly and toxic.... I had to deal with the oder for a week. Good thing is that plate will never come off. I also could not use the short screws that came with the screen, I had to go to home depot and buy longer ones. Shark obviously didnt take into consideration the gap between the roof and the headliner. I paid $120.00 I think for my screen. I was trying to find a 17-21 inch, but then it would block my view to the rear. i think the 15 inch is a perfect size. It is lighter weight, and I can still some what see behind me. Also people in the front really see it, and the third row seats see it perfectly. If you go to big it may be stressful on the people in the second row, the screen will be right in there face.

    PS: Good Deals lists alot of thier stuff on ebay, so buy it through there. Reason i say this is because they will help you with any problems as long as you havent given feedback. As soon as you give feedback they will ignore you and drop you like your nothing. Even after I finally got the cable and constant back and forth emails, I decided to place positive feedback. I then had another issue with the screen (the refresh rate issue), and they wouldnt email me back. They had made an error and sent me a second screen with the cable, once I brought that up, all of a sudden they were willing to help me. In the end we got into a huge fighting match (tina (gooddeal customer service) is very rude and so am I, so 2 rude people equals all out war. In the end I had a repair shop look at it, and kept the other screen to pay for all the headaches I went through. The repair shop was really nice though. The screen had all this major spots all over it, it was literally unusable. They were so honest they tried it out and told me to lower the refresh rate and it will work. Most other people would have told me i have to have it repaired and all this blah blah blah.... I got lucky with them.

    HiJackZX1, how is the overall quality of the monitor? Is it sturdy? How's the hinge mechanism? Does it swing forward when you brake or swing back when you accelerate?

    I think I'd screw mine on the front edge to a beam because there's one in just about the right place but I might have to run some steel straps back to the next beam to stiffen things up and provide a good, strong mounting point for the rear of the mounting plate.

    With the refresh rate set down to 50 Hz do you have any issues with headaches or anything like that? Haven't seen an LCD at anything other than 60 Hz but I know that CRTs tend to give people headaches at lower refresh rates.

    Overall would you recommend getting it and saving a few hundred buck or just going for the Xenarc 15"?

    Thanks,
    Jeff

    Besides the refresh rate issues with the screen, the monitor is very high quality. The metal plate can become very hot in heat, but the monitor will never touch it, so its no biggie. The screen uses like a hexagon type system to keep the screen from moving, but because of this you have to use a bit of strength to close the screen, but I have slammed on my brakes going about 85 mph and it doesnt even wiggle. The screen was definately well thought when it came for car design.... I just hate that they did not make it more for VGA, but they made it more for composite. If they did design it for VGA they wouldnt have put such a bad refresh rate on it. Make sure your graphics card has the ability to adjust to a low rate of 50.... you can get away with also using 52. You can use 56 but with some minor spots that you can really see. If you use 60 it looks ugly. I could also be wrong about the refresh thing, remember they sent me the wrong one. Maybe the real VGA one will be different. You have nothing to loose, you could always send it back for a refund. I just didnt send mine back because it is very hard to find a VGA screen and I just wanted them to get me the cable.

    PS: remember you have to use Epoxy made to bond metal. I would buy one that has a force rating of 400 pounds. That is the one I got. Also you will have to buy longer screws from home depot, these are the screws that tie the screen to the roof plate. Also this screen has the IR feature so you can use IR headhones.

    Mounting Overhead Monitors:

    1) Remove headliner

    2) determine gap between headliner and roof. Typically 1/2" - 1/4"

    3) find a scrap of plywood the thickness of the above gap

    4) use Liquid Nails to attach the plywood to the roof


    5) let the Liquid Nails dry. You may want to clamp it in place (a bottle jack and a wood post works well)

    6) replace headliner and run wires (be sure to leave yourself access to finish running wires in a few steps)

    7) Have your beautiful assistant help align the monitor while you position it. Mark the screw holes in the monitor on the headliner.

    8) set the monitor aside and line up the holes you marked on the headliner with the holes in the metal mounting bracket and mark them on the headliner.



    9) cut a small slit in the headliner that will be covered by the monitor and pull the power and video cables through

    10) Use wood screws to attach the metal bracket to the plywood through the headliner.

    11) hook up the monitor and attach it to the metal bracket using the small machine screws that come with it.

    So the only thing holding it up is liquid nails? Somehow I'm not sure I would trust that after a few months of bouncing around and so forth.

    Well, this install is in my H3 and it does plenty of bouncing around off road.

    In my other vehicle this same setup has held up fine for the past five years.

    This is the typical method that professional installers use.

    In this picture from the opposite side you can see how GM has used adhesive to attach the roof skin to the roof support which is typical for automotive manufacturers. They also use adhesives in many other areas.
