Panel Uniformity

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 chances 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. A variation above 15% but below 24% can be considered adequate, but anything above this does not meet our basic minimum standards.

Considering how huge this monitor is, a panel variance of 20% is not all that bad. Of course with that being said the reason for most of this variance is due to the panel’s curvature, and creating the same brightness level across the entire screen is quite difficult. Overall we would consider these results to be decent, if not a standout for its class.

Panel Performance

In a perfect world a screen’s real world response rate would be so high that motion blur, ‘ghosting’, ‘reverse-ghosting’ would be a thing of the past. No matter how fast the action on screen all images would be represented in pristine condition similar in quality to a static image. This is not a perfect world, but the less amounts of blurring which occurs the less chances you will notice the issue in real world scenarios. While the panels response rate (ms) and and frame 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.

As expected the combination of a 75Hz refresh rate and FreeSync is a winning one. In this area this monitor is noticeably better than any 21:9 we have seen to date, and for gaming enthusiasts that is one heck of a reason to purchase this model instead of another offerings. At least with the panel’s overdrive setting to Normal, blur is nearly eliminated altogether.

Gamma Performance

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.

At 2.21 the Predator is close enough to being perfect that we honestly would not worry about it. To be blunt, the only people who will be disappointed with this minor level of deviation are professionals whose livelihood depends on producing perfect, accurate images – and those professionals will own a colorimeter and use it before they ever bother with ‘factory’ settings.
