Discarded keyboard and mouse! Dell multi-touch LCD in the first test "Multi-touch" is the last two years, along with Apple's iPhone, with a very fashionable one word, and now touch-screen has been widely used in mobile phones, digital photo frame, GPS navigation systems and other portable handheld devices, or large public information display them . With the latest Microsoft operating system Windows 7 multi-touch operation by adding the support of Dell, Hewlett-Packard, Acer and other traditional PC makers were the first to launch multi-touch display products, including LATITUDE D420 Battery's first to a model SX2210t appeared in the domestic market, becoming the first official sales of consumer-level multi-touch LCD display products.
● Multi-touch feature details
Dell SX2210t as the most unique feature LCD displays, multi-touch is naturally the focus of our testing. Adoption of this page in a video, I believe we have already SX2210t touch features already have a preliminary understanding, then we have them in more detail.
Pairs of readers a better understanding of mobile phones should be aware that most of the current touch screen mobile phone is divided into resistive touch screen and capacitive touch screen of two, including Apple's ubiquitous iPhone, the screen is the latter. However, Dell does not use a liquid crystal display SX2210t these two kinds of touch screen, it uses a solution that, through infrared sensors around the screen to locate the position of the fingers or other objects to achieve touch-operating functions.
Although the latest Windows 7 operating system can provide native support for multi-touch, but to be completely with your fingers on the LATITUDE D620 Battery operations still need specific driver support. In addition, we also need to use the USB cable to connect with the host after SX2210t in order to use this feature (video cable is only able to transmit video signals, while the touch command, as well as the camera via USB cable signal transmission).
When installed, the relevant process, we open the Windows 7 computer system, property management interface, you can see the system has been properly identified Dell SX2210t touch devices. At the same time, we can also see SX2210t support is a 2-point touch at the same time, both at the same time can only accept a maximum of two points instructions.
In addition, Dell installed the included SX2210t LCD Touch Screen Tools later, also in the system taskbar notification area, as well as the prompt area to display the corresponding icon can be used for users to set up and adjust it.
Support for a touch-operated equipment, its calibration, and other settings are very necessary, but LATITUDE D820 Battery's software SX2210t also added this feature. Users can set up using a stylus or finger operation touch the settings, is used to completely replace the traditional mouse operation.
The above settings are for some gestures, as well as some of the features touch pen to allow users to completely out of the mouse, all the operations of traditional mouse, the keyboard features do?
Windows 7 operating system provides a virtual keyboard, its keys exactly the same set-up and a regular keyboard. Activated touch feature, the keyboard will automatically appear. When we are not using it, when you can click the upper right corner of the "X" button to hide the side of the screen, and when necessary, we can then drag it out, and thus full realization of the keyboard functions.
For some less likely to use the keyboard to input characters in the user, the handwriting is their fastest, most convenient input methods. The Windows 7 also provides a hand-written interface, click on the virtual keyboard icon in the upper left corner of the first one can be handwritten, and very convenient.
From the above presentation, we can see that XPS M1210 Battery LCD multi-touch function has been fully able to replace the traditional keyboard and mouse, and watching the pictures, you can also, like Apple's iPhone as easy to select, zoom, zoom rotation and other functions and is compatible with most software. But here we need to mention is that, Dell SX2210t touch sensitivity relative to do not enough, the video above, you can very clearly understand that if the clicks are not in place, the system will not identify the operating instructions Therefore, sometimes give the feeling of insensitivity to operate, to a certain extent, affected the user experience, this is all future touch-display and one machine must address a problem.
In addition, Dell SX2210t in order to protect the screen from being scratched, using mirror-screen design. However, one of the mirror screen is easy to leave a big flaw in fingerprints, so after countless times touching, SX2210t the screen will become a "big Erhualian" very ugly, so maintenance is concerned, users need to spend more and more energy.
● the world's first multi-touch LCD performance testing
In the previous article, XPS M2010 Battery have already SX2210t Dell LCD monitor in detail the appearance of part of the introduction, it introduced the new Dell 21.5 widescreen SX2210 design is almost identical, so we first tested its performance parts. In the high-definition picture real shot test, we shut down all of its color enhancement technology and dynamic contrast ratio technology, and allowed to work more than an hour. As the results of the use of digital camera and display a certain access to the actual display, so these pictures are for reference only. Click the following pictures can be enlarge.
Although targeted at high-end home users, but the Dell LCD monitor SX2210t more emphasis on its multi-touch features, but not the color of their outstanding performance a priority. As a result of the color gamut up to 85% of the panel, so SX2210t are fairly easy in color saturation, although its overall sharpness and contrast with the optimization of the market with the same gate brothers SX2210 performance is very close to the market throughout the 21.5 widescreen at a medium level.
● racing game "Need for Speed 13" test
Now that has a 2ms response time, so I believe that many readers want to know XPS M1330 Battery monitor's performance in the game, after all, the high-end gaming performance is a concern to recreational users the most. Here we use the racing game "Need for Speed 13" for testing. In the test, we opened its dynamic contrast feature. The following pictures can be larger.
Dell SX2210t LCD overdrive feature can manually adjust the opening and closing, we recommend that readers turn this feature when you play the game. In the course of the game the screen real smear is not obvious, and support full HD 1080p resolution SX2210t also has a very delicate picture. In color performance, Dell SX2210t more natural style, relatively faithful to the reduction of color.
● Power Test
Next, we tested for leaky. In the light leakage test, we closed the SX2210t Dell LCD monitor features a dynamic contrast ratio.
Latitude Cpi battery is not particularly uniform, from the figure above we see all around the screen the more obvious light leakage phenomenon, for a high-end models in terms of average.
● Power Test
Finally, we conducted a power test. In the test, we strictly follow the state promulgated the "computer monitors energy efficiency standards" for testing. In the test, we all color LCD monitor Dell SX2210t control (hue, saturation, etc.) should be adjusted to the factory default values. Should not connect any external devices, including USB hub or port.
In the test, we show a selection from full black to full white gray-scale testing to provide eight pattern ( Latitude d800 Series battery) test, and the brightness of liquid crystal displays, respectively, adjusted to 100,75,50,25,0, and test the standby power consumption.
To make results more representative, we have specially selected a TN panel used the ordinary 21.5 widescreen LCD monitor power consumption results as comparison.
In the above icon, the green part of the ordinary 21.5 widescreen LCD monitor that the power consumption, while the yellow line that Dell SX2210t the actual power consumption. You can see SX2210t While there is no publicity is a low-power products, but its actual power consumption values than the average 21.5 widescreen LCD less 10W or so, a maximum power consumption of 26W, so it can play better energy-saving effect.
● the first appearance of multi-touch LCD Appreciation
Finally, we come with Dell SX2210t appreciate the overall appearance of part of the liquid crystal display. Before we have already introduced, SX2210t with the SX2210 look almost exactly the same, they are using Dell's new stylish two-tone design, compared to the previous plain has undergone great changes. But here we need to be raised is that, while the two looked like a pair of twins, but "brother" SX2210t of body weight a lot of obvious importance, which also used a more solid base metal material, so SX2210t in craftsmanship and materials used are much better than the SX2210.
As inclusion of multi-touch features, Dell SX2210t LCD SX2210 more solid than the fuselage, and adopted the mirror-screen design.
Studio 1535 battery is also equipped with a camera, for online chat. In addition, this model has built-in microphone.
It should be clear is that, Dell LCD SX2210t base metal used, and the previously released SX2210 is entirely different.
Dell SX2210t LCD interface is also very well equipped. In addition to traditional D-Sub and DVI-D dual interface addition, it also is equipped with HDMI interface. In addition, this model is also equipped with three USB downstream port, and a USB upstream port is to connect the host PC, use the camera and touch capabilities.
● test summary
Compared to other high-end LCD monitors, the Studio 1735 Series battery most important feature of liquid crystal displays is to support multi-touch function. Through our testing, we can see multi-point touch has been in function can replace the traditional keyboard and mouse, touch screen functionally completely replace the mouse, while the virtual keyboard and handwriting recognition feature, you can replace the traditional keyboard, Most programs are able to properly use. But feel in touch, SX2210t also need to strengthen their position and can not always very accurate, the user is not issued instructions are well completion.
Owing to the focus put on touch functionality, so Dell SX2210t performance in color and did not give us more surprises before the actual display of the SX2210 and the gap is small, as a whole, and the market average 21.5 widescreen LCD at the same level of . However, in leaky areas, SX2210t control of the more general.
In a few weeks ago, we ZOL display channel is also on the "Do you consider buying a touch display," conducted a survey of this topic, the results showed that about 55% of the netizens consider buying a touch display, you can see everyone is still on the LCD touch displays have a certain expectation. Now cell phones and mobile devices, touch screens have started large-scale epidemic, which also make online friends on the touch display more interest.
However, sorry for,Dell Precision m70 battery is subject to cost constraints, due to the relative size of LCD screen mobile phone to be much larger, so the resistance of the common cell phone screen and even the capacitance screen, in order to produced 21.5 inches, this cost increase is very alarming After all, it involves both the technical and technological level, and therefore the current use of mobile phone LCD screen, such a solution is certainly unrealistic, or expensive products are not going to go buy them? And the current one, therefore the same machine, the display will be greater use of infrared sensors such as Dell SX2210t device, but even so, the cost is still relatively high, SX2210t's offer to reach only 3999 yuan, the price of even than the Dell's use of IPS wide viewing angle with the door panel 24 widescreen U2410 more expensive than 500 yuan or so, so you can see, touch monitors, and will not be popular in a short time the general public products. This is also the number of display manufacturers have been adopting the attitude of wait and see or test the water, but has been reluctant to enter this market, one of the main.
Through Dell SX2210t testing, we can see the current consumer-level multi-touch display in compatibility performance to be better than previously expected, Windows 7 operating system (Home Premium or above) the native driver support, and improve the relevant , has been able to let most of the program is compatible with. However, the problem it faces is also very clear: One is the need for frequent touch-screen finger, and it will leave unsightly fingerprints, it will affect the monitor's overall appearance;In addition, due to cost constraints, can not touch the display being used, like Apple's iPhone, a high cost, as capacitive screen, so the touch will not feel so smooth as the iPhone, which will cause certain impact on the user experience. Of course, the deficiencies are talking about here is not simply a product only to Dell SX2210t this, but all current touch-display and one machine also need to address the problem.
In addition, too, Dell Precision m6300 battery had been looking forward to User: Future Touch Screen, after a large-scale popularization of the traditional keyboard and mouse it can be discarded, just as the phone's keypad, like disappear without a trace. But through our experience in the use and view the feedback received, the keyboard and mouse can still rest easy, first and foremost he has a feedback effect of touch is touch display can not do, not all users like the stiff screen, while the use of keyboard input Text will be more comfortable, more suitable for long-term operation of the office, as well as a computer programmer. In the touch operation, does not particularly good to replace the right mouse button, so play the game, players can not be passed by such a long way to replace the right mouse button, so totally can not adapt to fast-paced game, so the current status of the keyboard and mouse touch-screen can not be replaced.
In addition, we also note a detail, because the display was standing at the desktop, so when you touch the display did not get any arm support, so that a long time after use, the arm will appear the phenomenon of sour, so if the next touch display with the desktop to maintain a level closer to the point of view, so that users can use the desktop in operation to support the arm, it will not appear in the above-mentioned phenomena.
Of course, for those who are not familiar with computer-based users, touch is one of the most direct and most convenient mode of operation. Through iPHone successful experience, we can see that some programs or games more suited to touch screen, such as small game Lianliankan, playing the piano, and so are more suitable for touch screen, so in the future popularity of touch screen technology, in addition to the touch, as well as the further development of continue to reduce the cost of outside programs designed for touch screen and application is also a very important part, and only these three at the same time do a good job, in order for touch displays truly universal.
