Image Quality (Uniformity / Panel & Gamma Performance)
Please remember that the settings below have been calibrated for our specific environment and your viewing conditions may differ from ours.

In a perfect world a screen’s brightness output would be equal throughout the entire panel. This is not a perfect world, but the lower the variation the less chance you will notice overly bright or dark sections on the screen. For the consumer LCD marketplace a variance of 10% is our gold standard but anything below 15% can be considered excellent as we doubt anyone will notice a -7.5 to +7.5 variation from section to section. A variation above 15% but below 24% can be considered adequate, but anything above this does not meet our basic minimum standards.
Typically when you combine an inexpensive price tag with a second tier manufacturer the end result will be nothing short of useless. The Nixeus NX-VUE24A is obviously not your typical monitor and these results may not be even in the top ten, but a variance of only 14% is still darn decent. It also happens to be significantly better than some of the more expensive TN-based screens we have come across.
When it comes to gaming monitors, onscreen blur is an extremely distracting element that many have simply grown accustomed to. While the panel’s response rate (ms) and and refresh rate (Hz) can give a fairly rough idea of how much blurring to expect it is not the end all and be all.
To this end we have taken PRAD’s Pixel Persistence Analyzer ‘Streaky Pictures’ program and using a high speed camera captured exactly how much and what kind of motion blur you can expect from a given monitor. Essentially, the less “after image” in the picture below, the better.
In this case we enabled FreeSync and V-Sync which, in addition to the monitor’s ingrained 144Hz abilities, completely cleaned up the image and eliminated all ghosting. For any monitor this result is bloody marvelous, but for a $300 rang product it is downright amazing. Obviously Nixeus never got the memo that a buyer has to spend a lot of money in order to get crystal clear images at high speeds.
Naturally, with the limitations of FreeSync + V-Sync enabled alongside one another, there is a certain amount of judder that happens at lower framerates as they jump back and forth between refresh rate steppings but that can be easily eliminated by insuring performance remains above 60FPS.
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 underexposed shadow detail or washed out with too little black level detail (aka being over-exposed).
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.
Even though this monitor is not factory calibrated, a result 2.23 is more than tolerable and actually quite good all things considered. Honestly, we would recommend trying the VUE24A out for a few days before trying to manually correct it as it may be 'good enough' for your needs.
