Resource TheVerge conducted an experiment with a new laptop Apple MacBook Pro, equipped with 15.4-inch Retina-display with a resolution of 2880 × 1800 pixels and pixel density of 220ppi. In this model there are two Port Thunderbolt and video output HDMI. Therefore, the question arose whether the device displaying the image simultaneously on four displays (own display, and three connected external monitor)?

For the purpose of the experiment to the ports with Thunderbolt adapters DVI-to-MiniDisplayPort were connected to two monitors with Full HD resolution of 1920 × 1080 pixels. Through the HDMI interface was connected to a monitor with a resolution of 1600 × 900 pixels. As a result, the laptop could display an image on all four displays. In this case the total image resolution was 10.7 million points. It is noted that the laptop cope with the withdrawal is not only a static image, but when you start applications, move windows on the surface of your desktop and run the video in 4K resolution, followed by the movement of the player window is not seen any slowdown output. However, when it was launched four separate video for each display (one of the video was available in the resolution of 4K), yet there were reducing the frame rate.

A similar test was carried out, and journalists shared on OWC. They connected the monitor with a resolution of 2560 × 1440 points to the ports Thunderbolt and monitor with a resolution of 1920 × 1200 pixels to the output HDMI. The total image resolution was 14.9 million points. In this case, the movement of objects and video playback on all four screens also led to delays. But still it’s a great result for Retina display.
