Colour Operation and Calibration

With a new panel on-board, I was curious to see how the Predator X34P stacks upward in colour performance, particularly every bit the X34 is an fantabulous monitor out of the box. Unfortunately, the aforementioned tin can't be said of the X34P, though with a few tweaks this monitor can deliver decent results.

The main problem with the X34P out of the box is white residue: by default, the monitor is besides warm, with a white point around 6000K and an boilerplate of 6185K. This screws with grayscale performance as you tin can come across, with a deltaE average of 4.68 and gamma that's completely wrong. On the other mitt, the X34 is nearly accurate by default, with a much better CCT average that leads to a sub-1.0 deltaE average in grayscale.

Default Scale

Poor color temperature skews color operation in saturation and ColorChecker tests, once again producing deltaE averages to a higher place iv.five. Had Acer shipped the monitor with a better color temperature, more in the line of the original X34, functioning would have been smashing equally the monitor is capable of 98.seven% sRGB coverage.

OSD Scale

With the following gear up of tweaks in the on-screen display, you tin can get the Predator X34P dorsum on runway to producing great colors. Note y'all volition have to prepare the gamma to 1.9, rather than the default ii.two, equally the 1.9 gamma mode actually produced gamma 2.2 in my testing. Strange, simply that's how it is.

The primary thing to note is making these adjustments to the X34P does reduce the dissimilarity ratio to around 830:1, whereas the X34 tin maintain a 1100:1 dissimilarity ratio with similar operation. That's a notable departure and a central negative impact to the different display used.

Setting Default Calibrated
Brightness lxxx 77
Contrast l fifty
Color Mode Warm User: R=42, G=42, B=46
Gamma ii.2 1.9
Overdrive Normal Normal

On a more positive note, you can attain pretty decent functioning with a few OSD tweaks. The panel doesn't perform as well as the original X34, only deltaE values around 1.0 across all tests is still very skillful without performing a full scale. Color temperature I slightly too loose at the depression cease, though gamma is stock-still and merely a few color points exceed a deltaE of 2.0.

Full Calibration

Even better greyscale operation can be achieved through full scale using SpectraCAL's CALMAN 5 software. In particular, the color temperature curve is flattened and greyscale functioning improves to a sub-0.5 deltaE. Saturation and ColorChecker results remain largely unchanged, withal with deltaE values near one.0, this is a decent place to stop upwards anyway, particularly for a gaming monitor.

However it's disappointing to see the X34P unable to match the X34 at whatever phase. When fully calibrated, my X34 achieves sub-0.5 results in the saturation and ColorChecker tests while maintaining a decent dissimilarity ratio. It'due south unlikely anyone would exist able to tell the difference between this and the results put up by the X34P, but it's clear the older panel is meliorate from a colour functioning standpoint, and more than importantly, comes better calibrated out of the box.
