    Looks neat, maybe you could recommend it to mp3car store as an alternative to the MIMO and LILLIPUT. I should buy one and try it out!

    For $80, it looks like a pretty good deal. The only deal breakers for me would be if there's no way for it to power on automatically (can't find a manual to download, since the company doesn't have a web presence) and if there is no VESA mount (doesn't look like there is one, and can't verify because of the lack of a manual). Probably not bad for the back seat, as long as there isn't direct sunlight around, since 250 nits isn't the brightest around. I'd also be concerned about a driver collision when installed with another touchscreen monitor.

    Hopefully someone buys one soon and does a proper review in a car environment. The video review at Tiger Direct doesn't go into the kind of depth we carpc users would like.

    Understandable about the brightness being an issue. For me personally though I have window tint and don't have much of an issue there.

    The On/Off Button could be an issue. I don't see why it couldn't relocated, swapped out and mounted somewhere else. I'm not sure if it just a slide switch momentary to constant or if it stays in place.

    If the switch latches could leave in ON position and have PC relayed to start with run/ignition. I'm sure there are possibilities.

    I will dismantling the case as it is just slightly too large for my dash and flush mounting the screen.

    I figure I will purchase one in the very near future and I'll let you guys know how it goes. In the team anyone else have any caveats or opinions? Thanks!

    displaylink drivers turn on/off the display when the comp is powered on/off automatically. They all work that way

    these usb screens have always intrigued me..

    if i get really bored tomorrow, i might try to swing by my local tiger direct/compusa to see if they have those in stock..

    but i have to ask-- what does this screen offer over comparable lilliput/mimo products?

    usb screens actually work really well. my only gripe is the cpu power they eat up. if you have an atom setup, dont even bother because one of these screens eats like 20-30% of your cpu power at all times.

    but for CULV or desktop cpu's, its not a big deal to have one or two of these screens. theyre fun items to play around with.

    well, i bought one..

    first-- there needs to be some clarification:

    there are 2 models of this monitor:
    the P16-40921 is a non-touch screen monitor, and is currently on sale for $80.
    the P16-40922 is the touch screen version and is currently on sale for $100.

    both of these prices are still very competitive to the Mimo versions of the same screen. looking at pictures of each, it uses the same bezel, and mounting stand, as the $180 "Mimo iMo Pivot Touch"

    when i was at the store, they originally tried selling me the non-touch version of the screen until i checked the model number of the link the OP posted.

    the box will say "Mini USB Touch Screen Monitor" exactly like that-- so if it doesn't have Touch Screen in the title, it is not the touch screen model..



    it took me a while to understand how to setup multiple monitors, but it DOES work with the standard lilliput touchkit driver. it uses the same driver, but with different logo/branding on it. in fact, when i went to try it out in the car, i first tried installing the touchscreen driver they included--which attempted to uninstall my lilliput touch screen driver.. it didn't work consistently on my in-car pc but that was because i am pretty much at the 5v-rail limit of my ds-atx-- when the dvd drive spun-up to load the driver, the display turned off... on my laptop in my house, it is working fine..


    this image is my older LED-backlit lilliput 629, the Proximus screen, and my laptop(which i believe is LED backlit)(crummy iphone pic)



    the touchscreen has a cheap plastic-ey feeling to it-- though, from what i have read, the Mimo screens have the same 'feel', though touch response seems to be about as good as the 629.. it also seems a little bit glossier then the 629, which would be bad in-car.. and the glossy frame doesn't help much either..

    the display appears to operate in a lower color bit mode(i am guessing something like 26 bit instead of 32 bit). it isn't noticeable until there is a image on the screen with lots of gradations.. i tried to take a picture of this effect, but my camera just can't pick it up very well..

    and then the resolution-- this screen stays at 800x480 when used in a extended desktop/primary configuration--there is no option to change it in the windows screen resolution window..(though other display programs might be able to force certain resolutions) when i duplicated the desktop to both the 629, and the proximus, the max resolution was 640x480, but i could lower the resolution to 320x240.when it was setup as a duplicate of the 629, the 629 scaled/stretched the image to fill the screen, but the proximus placed black bars on the sides to lower the resolution..


    for the picture quality, it is slightly darker then my 629. comparing them side-by-side, it just seems like the brightness is not high enough.. i played with the buttons on the back, and even made sure it was as bright as it would go..

    and contradictory to the 'quick facts' on tigers site, i really believe this is a LED backlit screen, as i don't see any color-temp difference between the 2 monitors like what i have seen when comparing other LED and CCFL backlit screens.. not to mention, considering the 5v source, i imagine it would be much cheaper/easier for the maker to use led's instead of building a whole buck/boost convertor for a ccfl backlight..


    and to confirm cpu usage-- my laptop uses a pentium dual core T4300 processor, with 3gb of ram, and was floating around 25-35%, with 50% spikes while playing a you-tube video on the proximus..

    Wow, thanks for the prompt review! So, is the Proximus or any other USB powered monitor is going to be a resource hog?

    I think I am going to along the route of display that has a headrest/dash mount bezel. As it will make it easier to integrate into my dash. I had just seen this and thought it was a good deal and wanted to pass it along to you all and see what everyone thought.
