Apple exhibited a LG UltraFine 5K at the press conference last year Display, LG UltraFine 5K from configuration The display can be said to be a special display that is completely customized for MacBook Pro. It not only supports the P3 wide color gamut that Apple has recently vigorously promoted, but also can achieve multi stream transmission. A lightning 3 data line can achieve 5K resolution drive and power supply for MacBook Pro, all of which are so perfect. But recently, LG UltraFine 5K Display users exposed some problems in use, that is, when LG UltraFine 5K After the display is connected to the MacBook Pro through the Thunderbolt 3 interface, the transmission speed provided by the USB expansion port provided by the display is actually constrained. Some users specially equipped a Sandisk Extreme 900 2TB SSD RAID for testing. From the actual test results, the reading speed of large files is only 348MB/s, and the writing speed is only 317MB/s. If the MacBook Pro is directly connected, the reading speed is up to 887MB/s, and the writing speed is up to 723MB/s. Moreover, the transmission speed will be further reduced with more and more drives connected to the display. At present, Apple and LG officials have no explanation for this problem, which is quite embarrassing.
