I've had dozens of tablets cross my desk, and their display quality has varied dramatically. When I look at a tablet's display quality, I judge it on a number of criteria: brightness, color accuracy, contrast, and image clarity. The last point is a tricky one, as it covers image sharpness and detail as well as text sharpness, areas that can be influenced by how well a mobile operating system renders those elements in software.

Rewind to the debut of the first Android 3.0 Honeycomb tablets--those early models running Android 3.0 all suffered from a bug that caused digital images to render improperly in Google's Gallery app, the default program for viewing pictures. Images looked fuzzy, with little detail. Google quietly fixed the bug later, in Android 3.1; nevertheless, image reproduction could be better, and the Gallery still natively displays images in just 16-bit color.

So where does that leave the discerning buyer hoping to get the best tablet display possible? To find out, the PCWorld Labs lined up eight tablets and compared their image quality side by side. Our testing is ongoing, and we will fold the results into our ratings for tablets in the future. Right now, we can offer a glimpse of our early findings.

This first pass of our subjective testing focused on images and color, not text. Our jury reviewed four identical images on the eight tablets, with brightness settings on max for all. What we found was a bit surprising, in that the images varied dramatically and noticeably. During my earlier hands-on testing, in which I compared all comers with the standard-bearer, Apple's iPad 2, I had noticed some differences and issues--but to see the variety in a lineup was something else altogether.
