The Good IPS, 1080p panel at a fantastic price. Great stand. Four USB ports.
The Bad No HDMI. The display is too sharp. Another inversion test failed than the average.
The Bottom Line Considering its price, no one else has an excuse to buy a minor TN panel. While the color accuracy details didn’t pay the same attention as the 2209WA or U2711, the U2311H does make an attractive purchase if you want to get 1080p available.

Although the monitor fails four of these tests, the U2311H hits five more than we used to see.
Measured against the Samsung SyncMaster 975p CRT and using the Canon 40D, set at a shutter speed of 1/320, an average of over 60 photos were taken, using StoppUhr as a virtual stopwatch to choose from. The U2311H averaged 16.15 ms or one frame.
ΔE is a measurement of how much the measured color deviates from its expected value, allowing us to determine the accuracy of the monitor colors. Although the value of ΔE 1 is considered acceptable as long as it is less than 3, the shift should not be too obvious. HCFR was used to determine ΔE for the monitor.
|Measured levels (sRGB mode)|
|Black level (cd/m²)||0.27|
|White level (cd/m²)||293.82|
|Colour ΔE (compared to sRGB)|

Here, we only have control over the RGB values, so we can’t shift the secondary to help us make colors more accurate – we have to comfort ourselves by just trying to get the best grays.
|Black level (cd/m²)||0.18|
|White level (cd/m²)||139.67|
|Gamma (target 2.2)||2.20|
|Colour ΔE (compared to Adobe RGB)|

Our grays are much better – it’s a shame we won’t be able to unscrew these primers and secondary a little, but at the price this monitor goes, we’re not hoping for the extra functionality.
Viewing angles were made using the Canon 40D in spot metering, with only shutter time adjusting for good exposure.

Backlight uniformity was measured by placing the HCFR in free mode, displaying a fully white image and recording brightness along a 5×3 grid on the screen. This should be considered as a guide only, since the uniformity of the backlight can vary from one unit to one.

Although there was no light blood flow, the U2311H suffers from the “white glow” effect of the IPS on the dark screen.
It is important to note that the effects of light bleeding are likely to vary from monitor to monitor, regardless of size.
We measured energy using a Jaycar digital energy meter. It is important to note here that due to the limitations of the meter, the measurements are limited to 1 W or more and reported in 1 W increments.
All measurements, brightness and contrast of the screen were set to 100 percent and the test image was displayed.
|Maximum power draw||35W|
It may not be the bravest monitor we’ve used, but the power save and shutdown modes are exactly as they should be. Often, monitors still draw power even when off.
Dell offers a three-year warranty, which can be upgraded to a four-year warranty of $ 27.50, or five years of $ 46.20. This includes an exchange for the next business day.
Dell’s dead pixel policy varies depending on which monitor you purchased. For the U2311H you only need one bright sub pixel to get the swap; but if you have a dark pixel, you will have to wait five more to get a replacement. You may return any monitor within 15 days from the date of invoicing to Dell; however, the user pays for the shipping in this case.
Considering its price, no one else has an excuse to buy a minor TN panel. While the color accuracy details didn’t pay the same attention as the 2209WA or U2711, the U2311H does make an attractive purchase if you want to get 1080p available.
