Judging the ViewSonic ViewPad 10Pro screen is a bit challenging because, in a side-by-side comparison, there's no way to pull up the same Android interface on another 10-inch tablet.
We had to compare the Android 2.2 virtual window on the ViewPad 10Pro to the Android 3.1 operating system on other tablets.
Still, the ViewSonic ViewPad 10Pro screen isn't that amazing.
Its 500:1 contrast ratio is partly to blame, but the real culprit is the screen technology. We're used to seeing AMOLED screens and IPS technology that makes a tablet viewable from almost any angle, in a bright and colourful resolution. The 10Pro uses older LCD technology and runs at just 200cd/m2. At an angle, you can barely see the icons.
Movies looked washed out – we tested several HD films including a 1080p rip of the movie Priest, and the screen was so dark that we could barely see that there was anyone on the screen.
In a side-by-side playback with the same movie running on the Samsung Galaxy Tab 10.1, there was no comparison. The ViewSonic ViewPad 10Pro playback was too dark, with a poor refresh rate.
