Pressing any of the right-side keys on the P2714T brings up a small screen that tells you the function of each button. A second press of the third button opens the OSD. The first menu up is the brightness and contrast control.

This brightness slider actually controls the backlight, not the black level. Both are set to 75 out of 100 by default. Seventy-five is the highest contrast setting that won’t clip detail, though reducing it to 68 improves the white balance accuracy of a 100-percent signal. You’ll see what I mean when you read the grayscale results on page six. The button icons are visible on the right side. These change depending on context. It’s a very intuitive way to control the OSD, and I took to it immediately.

Here you can select from one of the four inputs. The P2714T can automatically sense an incoming signal, too. The grayed-out Auto Adjust menu is only available when using the VGA input. Using it sets the pixel clock and phase for analog signals automatically. You can fine-tune those options in the Display Settings menu.

Input Color Format toggles between RGB or YPbPr signals. RGB is the choice for computers and some DVD or Blu-ray players. If you hook up your player and the color looks strange, it’s probably outputting YPbPr, so you’ll need to switch the P2714T over manually.

There are eight picture modes on the P2714T. Standard is very accurate and is also the default setting. You might assume that the Movie mode would be a little warmer in color temperature than the others, but it is in fact very blue in tint. It also enables Hue and Saturation controls, which can help you adjust the appearance of fleshtones. Only the Custom Color mode allows fine-tuning of the white balance.

Aspect Ratio choices are 16:9, which uses the full screen, and 4:3 or 5:4, which shrink the image horizontally. The grayed-out options Pixel Clock and Phase are for analog signals-only. Dynamic Contrast is disabled in all the picture modes, which we applaud. If you get lost, reset is only a couple of button clicks away.

You’ve undoubtedly noticed the Energy Use meter at the top-right of all the menus. It rises and falls mainly with the level of the backlight. Turning up the brightness increases your energy usage. Energy Smart works like a dynamic contrast control. Darker content is made darker and brighter content is made brighter, ultimately reducing your overall energy footprint. For the best image quality, leave this set to Off. The other options control the on-board USB ports and the power LED.

There are no position controls in the Menu Settings, but that’s OK because the OSD always comes up in the lower-right quadrant of the screen. You can change the transparency and timeout values, however. And you can lock the settings if you wish.

DDC/CI allows two-way communication between the P2714T and your computer, and should be left on. This is the first monitor we’ve seen with any sort of screen conditioning feature. Turning it on runs a series of screen wipes. While this is useful for plasma panels, instances of image retention on LCDs are pretty rare.

You can assign the top two control keys to different shortcut functions in this menu. The choices are picture mode, brightness/contrast, auto adjust, input, and aspect ratio. While there is no separate signal info screen, the current input, resolution, and refresh rate are displayed at the bottom of every OSD window.
Dell P2714T Calibration
This is a rare example of a monitor that does not need to be calibrated. The grayscale in Standard mode is so good out of the box that you really don’t need to make any adjustments other than brightness and contrast. Normally we set contrast just under the clipping point, which in the case of the P2714T matches its default of 75. However, to reduce the blue error of the 100-percent signal, we lowered the contrast to 68. Because of this, we had to increase brightness, which actually controls the backlight, to compensate. To achieve an even better grayscale, we made tiny adjustments to the RGB sliders. Our calibrated settings are listed below.
| Dell P2714T Calibration Settings | |
|---|---|
| Brightness | 87 |
| Contrast | 68 |
| Preset Mode | Custom Color |
| RGB | Red 99 / Green 100 / Blue 98 |
| Sharpness | 50 |
The Sharpness control appears to do nothing below its default setting of 50. Even though available integers range from 1 to 100, there are only 10 steps available. Values of 60 and up introduce visible edge enhancement. We recommend leaving it on 50.

- Touch Or Not, Dell's P2714T Is A Solid Performer
I said it's a crappy idea that's not going to catch on, and I'd prefer not to have to pay extra for it or sacrifice other aspects of the display, like resolution in this case. That said, the companies can put their R&D and marketing $ wherever they want, not my money, but it's still dumb.
So instead of injuring your arms from repetitive stress holding them up in front to touch the screen, you are going to get RSI, cramps or other problems in your neck for staring at a steeper down-angle for too many hours a day... or get both problems, albeit over a longer term than either extreme, if you put the touch-screen somewhere in-between.
This is going to be 'fun' 10-20 years down the road. (As in lawsuits due to not being warned by device manufacturers that extended use of their device in a typical setup may lead to injuries.)
On the plus side, as long as it is only the glass cover getting dirty, it is much easier to clean than a keyboard or mouse.
Kiosks is a nice use of touch since it is pretty easy to "secure" those by simply omitting unwanted access in the UI design with the rest of the system physically locked out - touch-based kiosks have been around for a long time: the first time I have seen a touch-based terminal was in a video rental store about 15 years ago and the menu was in good old 80x25 text mode.
Industrial touch applications are nice too since you can seal the display on the "dirty" hot side of the application and lock the rest on the "clean" cooled weatherproof side.
For everyday computing, touch may also have its uses such as when demonstrating stuff: instead of demonstrating software or page layouts by pointing things out on the screen with fingers and then using a keyboard/mouse to activate the object or navigate pages, clickable things can be demonstrated on-screen - you already have your fingers in there to point things out anyway.
