Our viewing angle measurements produce results in both the reduction of brightness and the colour deviation at different angles while also comparing to the standard deviation. This value is based on the results of multiple tests of main and support colours and 100% and 75% white. If the standard deviation is low then the brightness of all the colours will reduce evenly. If it is high, then we notice some colours shifting.
The two 27” VA panels from Samsung do not have great results in this test, especially the more expensive C27F591 while the 24” scored much better. The Philips 245C7QJSB, AOC PDS241 and the Eizo EV2451 lead the way, but the competition is close throughout, especially in the horizontal viewing angles. Vertically, the picture is different. When so many of the screens cannot be adjusted to the desired height it is all the more important to keep in mind. The TN panel of Iiyama does not surprise with its bad result, the BenQ’s VA panel also does not impress here. On the other end of the spectrum, the 27” Samsung comes out on top in this test.
