Viewing Angle Performance While Tablets are primarily single viewer devices, the variation in display performance with Viewing Angle is still very important because single viewers frequently hold the display at a variety of viewing angles, plus they are large enough for sharing the screen with others. The Viewing Angle can be very large if the display is lying flat on a table or desk. One important advantage of the Surface Pro 3 is its adjustable kickstand, which makes it possible to adjust the Viewing Angle of the display in the same way as a Laptop. That is not only convenient but also reduces any Viewing Angle effects. The Surface Pro 3 has a high performance IPS / PLS LCD display, so we expected it to show very small color shifts with Viewing Angle, and our lab measurements confirmed its excellent Viewing Angle performance, with no visually noticeable color shifts. However, all LCDs, do have a strong decrease in Brightness (Luminance) with Viewing Angle, and the Surface Pro 3
45 showed (as expected) slightly more than a 50 percent decrease in Brightness at a modest 30 degree viewing angle. See the Viewing Angles section for measurements and details. Viewing Tests With its relatively accurate Intensity Scale and very accurate colors the Surface Pro 3 provides very nice, pleasing and accurate colors, and picture quality. The very challenging set of DisplayMate Test and Calibration Photos that we use to evaluate picture quality looked Beautiful, even to my experienced hyper-critical eyes. However, viewers that like vivid or exaggerated colors and image contrast may find the accurate Surface Pro 3 images to appear somewhat subdued. Display Power Efficiency While the Surface Pro 3 display is considerably larger in area than the other Top Tier Tablets and would normally be expected to require considerably more power, its display is more power efficient and it actually uses less power than many smaller Tablets. For example, for an equivalent area and display brightness the Apple iPad Air display uses 66 percent more display power than the Surface Pro 3. This is due in part to its lower pixels per inch, which affects the display’s power efficiency, but it is also the result of using higher efficiency White LEDs and optical stack in the Surface Pro 3 display. See the Display Power section for measurements and details. Surface Pro 3 Conclusions: An Excellent Top Tier Display… The primary goal of this Display Technology Shoot-Out article series has always been to point out which manufactures and display technologies are leading and advancing the state-of-the-art of displays by performing comprehensive and objective Lab tests and measurements together with in-depth analysis. We point out who is leading, who is behind, who is improving, and sometimes (unfortunately) who is back pedaling… all based solely on the extensive objective measurements that we also publish, so that everyone can judge the data for themselves as well… An Excellent Top Tier Display:
