There are dozens of 15.6in portable monitors available on Amazon, many costing around £100, so you may wonder why anyone would consider paying over four times that price for the ViewSonic VP16-OLED. The first clue is in the name: including an OLED panel rather than IPS immediately puts this display on a different pedestal.

But the real reason is quality. Cheap portable monitors usually reward you with poor color coverage, low brightness and lackluster color accuracy. What ViewSonic promises is much more in line with a professional monitor. With Pantone validation and a guaranteed average Delta E of less than two, you can be confident of the colors you see. This was borne out in the tests for our review unit, with typical averages of around 0.5.

I say “typical” because this monitor ships with numerous color modes: user, DCI-P3, sRGB, REC.709 and DICOM. DICOM is a medical standard, while REC.709 is used in broadcasting and similar to sRGB. That means it’s conservative in terms of coverage, so for the punchiest colors you should choose DCI-P3.

When testing such profiles, we’re always looking for it to clamp down on the gamut as much as possible. That’s why it was comforting to see sRGB lock the panel to 96.4% coverage out of a 98.6% volume. So, only a tiny fraction of the colors you see on the VP16-OLED will sit outside the sRGB gamut when you’re in that mode.
