Competition for the Microsoft Surface Pro: Acer Aspire P3, Lenovo Yoga 11s and Toshiba WT310

Generation Y


Screen quality

We always test the quality of the screens of laptops and tablets. The Microsoft Surface Pro is the smallest at 10.6 inches. The Lenovo Yoga has an 11-inch screen and the other tablets have 11.6-inch displays. They're all IPS panels, with good viewing angles. The resolution of the Acer P3 and Lenovo Yoga 11s is 1366x768 pixels, while the Surface Pro and the Toshiba WT310 have a Full HD resolution of 1920x1080. For a computer screen, it's important that the brightness is spread evenly in the greyscale from black to white, and that the primary colours are where they should be in terms of colour fidelity.

In the grey radient you can see that the primary colors individually have pretty good gamma values. The collective gamma values of the Acer P3’s, Lenovo Yoga 11s and Toshiba WT310 are each too low, due to a dip at 90 percent white. At that point the screen are lighter than they should be compared to the other steps from 0 to 100 percent white. The gamma of the Microsoft Surface Pro is slightly too high, which makes the screen somewhat darker than it should be. These variances are only partially visible on the Acer and Toshiba tablets.

The color range of the four tablets is about the same. It's narrower than the sRGB spectrum, which you can see the best with blue and magenta. The individual brightness of the colors isn't great, with large peaks for blue and a smaller one for magenta. In the DeltaE 94 test, blue and magenta score poorly.

Toshiba WT310 and Microsoft Surface Pro

The color temperature of the Acer P3 and Toshiba WT310 is close to the ideal 6500 Kelvin, but are therefore slightly bluer than they should be. The Lenovo Yoga 11s and Microsoft Surface Pro have a large variance towards blue, and are around 7300 Kelvin. The maximum brightness is good on all tablets, except for the Toshiba WT310 with 296 cd/m². The contrast of the Acer P3-771 is the lowest with 846:1, with the others around 1000:1. A contrast of 500:1 is normal for a laptop. 

The quality of the Surface Pro screen is generally somewhat better than those of the others in this test, with the sidenote that the color temperature is slightly too high. The color range is a bit limited due to undersaturation, but the brightness and contrast are very good. For general use these convertible laptops/ tablets are fine, but we wouldn't use them for color critical work.
