good for the price; some unpublished details

Handles only two finger touch screen gestures (spec in the manual), which could well be sufficient. The similar optical sensor Compaq specs 3-touch, at similar prices though not as much discounted. Apparently iPads use more fingers; large screens with that very expensive. Screen is responsive, unlike some optical ones in palm sizes. The optical touch sensor allows a very rugged screen surface.
The touch screen was recognized by Windows without installing Viewsonic drivers, apparently handled by Logitech mouse support software. Seems to be a standard input device now. The touch feature appears as a pointing device or mouse in Windows.
For the price seems well built and functional; more function costs a lot more.
Can be connected with an HDMI cable through a simple plug adapter, but the HDTV resolution 1920 x 1080 will show letterboxed indented 7/8" each side. [can be fixed in settings; see comments] This does not occur with a DVI video card. Older widescreen monitor format 16:10 1680 x 1050 shows full screen with adapters for pc use. A high end VGA/RGB interface should work but many older video cards do not present high resolutions on that output, giving more on a DVI output. There is no apparent difference in the video signals in these cases because the unit is able to present the 1920 x 1080 image, and there is only a simple pin-to-pin mapping in the HDMI adapter. I suspect there is an HDMI licensing issue and some restriction on displaying HDMI output unmodified without a license; the DVI is noted as HDCP, the industry copy protection system, despite not HDMI. An older issue of aspect ratios with computer monitors being 16:10 compared to TV's 16:9 does not apply, as the dimensions of this screen really are 16:9 and it works that way on DVI. Unfortunately I do not have access to the competing products to see if they also handle signals in this peculiar way. Newer ones probably have HDCP and do the same thing.
The DVI connection lacks Digital Rights Mgt handshaking with HDMI TV devices, DVR's etc., so even with an adapter those will not connect.
Monitors must have a true HDMI jack to use those inputs, and cost more because of royalties besides the hardware. Touch screens in large sizes are little benefit for TV program play as viewer is not within reach, compared to smaller tablets held close. If really needed, a processing box type adapter might work, at extra cost.
The screen is not as anti-glare as coated screens though specified as anti-glare, but such coatings cannot be used on a touch screen -- and get worn off even on regular monitors. Ironically the boiler plate manual includes a warning not to touch the screen because of finger dirt. There have long been add-on glare screens however, including a hang-on type from ViewGuard (usually reserved for the different privacy filters, which aren't anti-glare at all).
A simple plastic stand is included at the low price, fastened with the VESA attachment instead of separately, so the metric size screws are provided. All sorts of VESA attachment stands are available at extra cost from various suppliers. The low power LED display needs less stand-off from a wall as older fluorescent screens, less hot. Has 4" spaced VESA attachment holes.
Added note on anti-glare: some made by matte finish instead of coatings -- picture frame plastic sheet available in this for example. But it can reduce crispness of images, matter of taste. Seems mfg's have moved towards polished surfaces, probably to make more impressive, and you can stick on a matte finish film if desired.
