Alienware Aurora R9 desktop and Dell UltraSharp U2720Q monitor. 1. All built-in monitor tests are also OK. 2. I've tested ... using a variety of tests from Dell website   1. Then I would not worry.  2. If you don't mind, can you describe or link to the Tests that produced these (frankly unacceptable) test patterns. Looks like maybe the test-images are not of sufficient quality for this high-end monitor.  For Testing, I would recommend DisplayPort cable and turn the ComfortView stuff off.
Dear colleagues, I've recently bought my Alienware Aurora R9 desktop and Dell UltraSharp U2720Q monitor. I've tested their hardware and software using a variety of tests from Dell website and built-in tests (computer and monitor built-in tests)  and encountered the following problem with interpreting results of two of the Dell website monitor tests. The first test demonstrates certain graphical artifacts between pink and red color stripes. Analogous artifacts are less visible between the other color stripes. Moreover, if one takes a closer look, a certain granularity is also visible on the black stripe.[IMAGE] In the second test, a high contrast straight line is visible between light green and pink color stripes as well as between red and blue color stripes.[IMAGE] Can you assist me with interpreting results of those two tests? All other tests with my video card and the monitor worked out flawlessly. I tested different video cables, including DisplayPort and HDMI, with identical results of those two tests. Does it mean that my video card is seeming to be defective? All other Dell website monitor tests are OK. All built-in monitor tests are also OK. Thanks in advance, Konstantin
