5.0 out of 5 stars good for the price; some unpublished details, December 15, 2012
This review is from: ViewSonic TD2220 22-Inch Screen LED-Lit Touch Display Monitor (Personal Computers)
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.

You can get rid of the "letterboxed indented 7/8" each side in the HDMI mode if you dig around a bit with the settings. Don't own the screen but this is a common setup problem with all HDMI monitors when you first install with windows... Forget the actual place to make the change but could look it up if you need me too. Edit: found it, go into the scaling options and set the overscan to 0%. Happens with all screens, and you need to make this change to get rid of the "letterbox", so get it back into HDMI mode! ;)

Nothing in Catalyst, ATI screen control, nor in the monitor, on overscan I can find. Where are these settings? Might depend on video card type.
Thanks for the tip.
This monitor is an LED upgrade of their discontinued fluorescent version otherwise similar VX2258WM, with Win8 drivers as well.
[added: Catalyst has advanced/basic menu selection to show more options. Got the scaling bar up but wouldn't adjust, just a checkbox.
odd behavior, letterboxed the 1650 as well as the 1920, worse. Lots of complaints on web about HDMI from TV messy with PC's. ATI 5450 Radeon. Intel has different menus]

Fixed in ATI Radeon catalyst: trick is setting resolution first to 1920x1080, only then does the scaling bar become active. Display expands continuously as pointer moved to the right towards zero.
Bar inactive at 1650 resolution.

Many thanks to turtoni for pointing out this adjustment.

Added: cause of this problem is default configuration settings for HDMI outputs are for TV's expecting overscan, at least at TV resolutions. DVI outputs default without overscan for monitors which don't like overscan. Connecting HDMI outputs thru adapters to DVI plugs presents the TV oriented signal to monitors not so oriented, in the obscure overscan parameter. So the default configuration must be adjusted in the advanced, scaling menus in windows display control. Another effect besides letterboxing can be cutting off small borders of the image, when outputting DVI to a TV HDMI input with an adapter, the other way. Monitors with HDMI jacks might be insensitive to the parameter. All depends on each instrument. Point is the default settings in the drivers for the video outputs vary with the type of output in ways not usually seen.

This is going to sound like a stupid question. You said, "Handles only two finger touch screen gestures". Do you mean it has to specifically be 2 fingers or not more than 2?

I run a photo booth, I need a new montior and would like to go with a touch screen. Basically what I need is the software to start running and then the people in the booth push a button in the middle of screen to start the program.

No more than 2. You can do this in Windows 7 without upgrading to Windows 8 with this monitor, if that is the only touch, selecting an icon on screen. It reproduces what a mouse does, including scrolling. Cell phones and Pads, Windows 8, add more such as two finger spreading and contracting images. I don't use it yet so consult someone familiar.
