This relatively low resolution on such a large screen means there is a 0. It was also free of the off-centre contrast shift you see from VA panels and a lot of the quite obvious gamma and colour tone shift you see from some of the modern AMVA and PVA offerings. This is what many people will know as input lag and originally was the measure made to explain why the image is a little behind when using a CRT. There was some some slight trailing in the best case images as you can see above but overall the movement felt quite good. As a side note, this actually signifies our first look at a p resolution PLS panel in fact as we’d only seen p resolution panels in 27″ screens up until now. Laptops by Caitlin Petrakovitz Nov 25, A higher resolution allows the display of a more detailed and of higher quality image.

Since SMTT will not include the full response time within its measurements, after speaking with Thomas further about the situation we will subtract half of the average G2G response time from the total display lag.

Pixel Response Time Element. This showed very low levels of blur and had minimal issue with overshoot. The screen seems to interpolate the image well although you of course lose a lot of desktop real-estate running at a lower resolution.

Really liked the fact that the stand is adjustable up and down, can tilt slightly and pivot. In fact the static contrast ratio was crushed quite a lot in this mode to around The overall “display lag” is the first, that being the delay between the image being shown on the TFT display and that being shown on a CRT.

There are many various interfaces under the VESA standard, which differ in the size of the brackets, delll distances between the screw holes and their number. Thankfully most of the transitions measured had little to no overshoot so all in all it shouldn’t present a big problem here. We wanted to see how much variance there was in the screens contrast as we adjusted the monitor setting for brightness.

The average contrast ratio of the screen was Not something you’d see in normal use though at all. It is not as light or “semi-glossy” as some p27114h we’ve tested, like the BenQ BLPTbut users shouldn’t see any grainy appearance in practice here still.

27″ Dell P2714H – Specifications

In theory, brightness and contrast are two independent parameters, and good contrast is a requirement regardless of the brightness adjustment. The duty cycle the time for which the backlight is on is also important and the shorter the duty cycle, the more potential there is that you may see flicker.

Laptop Panel Parts Database.

In fact it was similar to what we’d seen from the PH, with a slightly higher error on this 27″ model. Good all-round performance from PLS panel. Click for larger version. Cyber Monday deals at Costco: Panel type There are various panel technologies.

Maximum response time Information about the maximum amount of time, in which the pixels change from one color to another. Other techniques which are being used since are not conducted by Thomas he is a freelance writer or based on this equipment or technique, and may also be subject to other errors or inaccuracies based on our conversations with him since. This in itself gives cause for concern to some users who have experienced eye strain, headaches and other symptoms as a result of the flickering backlight caused by this technology.


It would have been helpful to include an “aspect” option perhaps, to automatically maintain the source aspect ratio whatever it may be. The signal processing element within that is quite hard to identify without extremely high end equipment and very complicated methods.

In real use you are very unlikely to ever see p2741h full black or full white screen, and even our tests are an extreme case to be honest. By default the Game preset mode gave us a static contrast ratio similar to that which we’d measured in the standard default preset mode The “AD” presumably cell for “Advanced”, but in reality we don’t expect any changes compared with the “normal” PLS panels we’ve seen before.

Any dynamic contrast ratio controls are turned cell here if rell. We tested the screen at a lower x resolution to see how the screen handles the interpolation of the resolution, while maintaining the same aspect ratio of Tilt, mm height, swivel and rotate.

It should be noted that the brightness regulation is controlled by Pulse Width Modulation at a frequency of Hz. Power Consumption Stand by. Very good range of adjustments, smooth to move but reasonably stiff. The screens tested more recently in the top half are split into two measurements which are based on our overall display lag tests using SMTT and half the average G2G response time, as measured by the oscilloscope.
