The display is labelled SuperClear by ViewSonic, a reference to the AH-IPS panel from LG. This has a matt anti-glare hard coating, making it useable in most lighting conditions. The black bezel is similarly matt finished, an important touch for any practical screen.
Unlike the earlier VP2770-LED model, the VP2772 now relies on an external power supply, a laptop-style little brick on a cable, which we find a backward step in usability. A potential step forward is the specified 99 percent coverage of the AdobeRGB gamut, and 10-bit colour compatibility.
Also indicating a preference for the Windows audience is how dreadful the image quality appears when first set up in OS X. This was resolved after adjusting the screen's Sharpness control. There are just four settings here – labelled 0, 25, 50, 100 – and the default setting of '50' rendered on-screen text very poorly, over-sharpened and highlighting sub-pixel rendering colour artefacts. The ‘0' setting looked too defocused, while '25' was about right.
Performance:
In our standard chequerboard test for contrast ratio, the VP2772 met a consistent 560:1 result at 50, 75 and 100 percent brightness settings. The tone response was not so even, deviating slightly to 2.1 from the calibrated 2.2 gamma at lower brightness levels below around 40 percent brightness.
For colour accuracy (Delta-E) and colour gamut coverage, we recorded very strange numbers from our Spyder4 screen calibrator (Delta-E avg 13.25; 89% sRGB, 69% AdobeRGB) which we believe to be anomalous and not indicative of actual performance.
Luminance uniformity reached a maximum deviation of 14 percent (top left corner, 50% brightness). Most quadrants were kept within good 10 percent limits. We were unable to test the 10-bit credentials of this monitor.
