HP Makes Affordable 21.5" Touchscreen Win 7 LCD

By - Source: Tom's Hardware US | B 28 comments

Touch it! Feel it!

Besides all the new pleasantries that Windows 7 brings with it that addresses the niggles from Vista, the new operating system also features a Touch Pack that will add in plenty of touchscreen navigation and interaction options.

Of course, you can't just install Windows 7 and start pushing your greasy digits all over your monitor – you'll need new display hardware. Unfortunately, touchscreen displays are generally quite expensive, but hopefully Windows 7 will make touching your PC more popular and manufacturers will make products more affordable.

HP seems to be among the first to introduce a new monitor that's designed for Windows 7 Touch Pack. HP calls it the L2105tm, which is the first Windows 7 multitouch certified monitor from the PC maker. As the name suggests, the monitor features a 21.5-inch screen.

Rather than using a capacitive panel on top of the LCD, the L2105tm features optical touch panel technology that uses two cameras in conjunction with LEDs for detection of one or two finger touch. HP claims that its optical touch technology is just as, if not more sensitive than capacitive touch that many of you have experienced on smaller mobile devices. One finger is used to scroll through screens, while two fingers can replace a mouse to perform common multitouch gestures.

For more pinpoint accuracy (or if your fingers are covered in orange Cheeto zest), the L2105tm also includes a hard stylus that tucks away into the side of the monitor for easy storage.

Those interested in playback of Blu-ray movies will like the 16:9 1920x1080 resolution. For inputs, you're looking at DVI and VGA. Given its affordable price, it's not surprising that it features a TN panel that boasts a 72 percent color gamut, 5ms response time and viewing angles of 170 / 160 degrees.

The HP Compaq L2105tm Touchscreen Monitor launches tomorrow alongside Windows 7 and starts at $299. This will be HP's first touchscreen monitor aimed that the desktop user, but the company told us that the optical technology used in the L2105tm can scale to both smaller and larger monitors meant for the desktop.

    Use your keyboard, easier than that it's impossible.. ;) 

    I've had a TX1000 and I did try on CounterStrike, and yes, it was good, but I hated the fact that I was on a laptop. Now on a desktop? Perfect!

    Hmm, the stylus would be nice for drawing with, depending on the sensitivity of it... which is?

    No, I'm not retarded, I do that with my HP Touchscreen PC and it works amazingly well. That being said it is a 26" instead of a 22", but the idea is the same. I use a palm pilot pen for it.

    The LED and Camera tech has been out for awhile. Smartboard is the only company I've seen use it (just off the top of my head). If HP gets the cameras and LEDs as close to the screen surface as possible, this will be really cool. If there is even the slightest gap, the user will need to compensate for where he wants to touch and where it looks like he's touching unless he is directly behind his finger as he touches the spot.

    Didn't some kid at MIT make a multi-touch version using this tech?

    FYI The camera behind the screen can be calibrated for a constant offset

    This works great for the ipod touch and iphone, but I dont wish to have to cleanse my screen of grease every 10 minutes with a microfiber cloth...

    Sorry, no matter what features, I can't imagine paying $300 for a 21.5" monitor...

    Is the touch screen tech really worth turning $150 to $300?
    For photoshop and the such, a tablet would still be used anyways.

    I honestly fail to see were this is any better than a tablet PC (essentially a bigass iPod touch), or a normal tablet (for you photoshop Wacom junkies).
    A tablet PC atleast you can hold comfortably, while a screen is right in front of you.

    The only possible use I can imagine is product demostration...

    it could be cool, set it up built into a slightly elevated counter or desk. use it in the kitchen maybe for finding recipes, or in like an work room as a sort of tablet pc.
