Nixeus NX-VUE27P 1440P IPS Monitor Review
Panel Backlight Bleed
An LCD or LCD LED-based monitor relies upon either one or multiple sources of light to illuminate the liquid crystals so as to create a visible image. In a perfect world, all the light would either go through the open crystals or be reflected back into the interior of the display via the closed crystals. Due to the manufacturing process, most monitors exhibit light leakage around the edges of the monitor. This issue is called ‘backlight bleed’ and can drastically lower the contrast near these affected areas. This causes colors to have a washed out appearance, with blacks appearing to be more gray that black. Ideally, a monitor should have zero bleeding, but if the amount is judged to be fairly minor we will consider it to be adequate.
To determine the amount of backlight bleed a given sample exhibits, we have placed the monitor in a completely dark room and have taken a series of pictures of the monitor using a Nikon D810 with a 24-70 F2.8E VR lens. In between each shot the ISO is raised by one stop until a picture is captured that shows the amount of backlight bleed occurring.
For a monitor in this price range, the amount of backlight bleed is certainly nothing to write home about. We have seen worse and we have seen better. Thankfully, few users ever use their computer completely in the dark. Under more common viewing scenarios, this level of bleed is barely perceptible with mainly a washing out of contrast in the affected area.
Gamma correction is one of the hardest terms to explain. However, for our purposes the gamma correction of any electronics device is how bright or dark an image will be displayed on a screen.
All PC devices now use 2.20 gamma as the default. Any variance from this will result in an image being either underexposed – which will create black crush and reduced shadow detail – or washed out with overexposed highlights level detail.
While 2.20 is the gold standard, a minor deviation of 0.10 will in all likelihood never be noticed by anyone other than professional photographers. Higher levels of deflection however will be noticed by just about everyone.
It is obvious the Nixeus NX-VUE27P 1440P Monitor does not come factory calibrated, but that is to be expected as this is an inexpensive monitor. What was not expected was how poor the default really was. Since there is no real gamma adjustment built into the OSD – beyond on and off – people will have to opt for off panel options like driver software. Thankfully, a colorimeter is not that big of an investment, and one that will pay dividends for years and years.
