REVIEW: Dell U2711 Part 3

The rotating plate integrated into the base allows for rotation of 40 degrees right and left.

Side rotation function of 40 degrees on the DELL U2711.

Use in portrait position is not possible with the base provided. With regard to the panel size and resolution, however, this is nothing more than a slight downer. Nonetheless, alternative stands can be used thanks to the VESA100 fixture.

The heat that arises when the monitor is in use is dispersed passively through ventilation slots located around the monitor – i.e. there is no integrated fan.

The back of the DELL U2711 has numerous ventilation slots.

At a brightness setting of less than 100 percent, the backlight inverter makes itself known through a very faint, high-frequency sound, but we were only able to hear this sound directly above the ventilation slots. Special test images with hard contrasts give rise to an also faint humming from the integrated power unit. Thus, our test model is not completely silent, but this has no negative effects in practical usage. Since noise production is generally subject to significant variation within a series, however, we cannot make any absolute statements with regard to all models of this kind. Nonetheless, it is possible to work pleasantly and without noise disruption on our test model.

Power consumption

With the 27-inch panel and a relatively high maximum brightness, one cannot expect an energy-saving wonder for the worst case scenario. However, no-one is likely to want to work with the maximum brightness setting. With power consumption of 123 Watts, the DELL U2711 remains under the manufacturer’s indication, but this value is for use with the optional sound bar. At a practical brightness level of 140 cd/m², we measure power consumption of almost 70 Watts

Without a USB connection to the computer, the power consumption can be reduced further.

	Manufacturer	Measured
Maximum usage	138 W	123,0 W
140 cd/m²	n/a	68,4 W
Minimum usage	n/a	49,0 W
Energy-saving mode	< 2 W	1,7 W
Energy-saving mode without USB	n/a	0,5 W
Switched off	< 1 W	0,0 W
Switched off without USB	n/a	0,0 W

Connectors

The connectors of the DELL U2711 are located vertically on the back of the model. DVI-D (two), DisplayPort and HDMI inputs process digital signals. For analogue RGBHV signals, a separate D-Sub VGA input is provided. Video players are connected digitally via the aforementioned HDMI connection or via the analogue YPbPb or Composite inputs. There is no S-Video input, nor is there the option to play back RGBs signals (via Scart or 4x Cinch).

Two of the four USB inputs, together with the USB output, are located towards the back. The two remaining USB inputs are located at the side, as is the card reader.
