So many wrongs in this article. > To keep a 60 Hz refresh rate, you need to step down to 2K or lower resolution. Nope. 3440 x 1440 @ 60Hz is the highest res currently used which still fits half the bandwidth of DP 1.2, see here: https://linustechtips.com/main/topic/729232-guide-to-display-cables-adapters-v2/?section=calc&H=3440&V=1440&F=60&timing=cvtrb&calculations=show&formulas=show https://linustechtips.com/main/topic/729232-guide-to-display... > They are very likely DisplayPort Alternate Mode designs using four lanes. If a hub claims to support 4K @ 60Hz and USB 3.0 it doesn't necessarily mean it supports both at the same time. It can be convenient to have a flexible hub which, when connected to a monitor where two lanes are enough then USB 3.0 is provided, if you go above then it slows down to USB 2.0. At least one of the hubs linked from the article (very small with one power, one USB 3, one HDMI and a non-captive cable) is such, this was confirmed by one of the sellers, this device is available with many, many labels. The article also omits that many, many notebooks with a single Thunderbolt 3 port will not support multiple 4K @ 60Hz because they put only four DisplayPort lanes in there using a cheaper, lower power controller called the Alpine Ridge LP. And yes, that pos is still in use despite I hoped Titan Ridge will deprecate it. Dual port Thunderbolt controllers are all full bandwidth, single can be half or full. Hard to tell without looking up the TB controller used in the device on social media / stackexchange etc -- the manufacturers are often quite tight lipped on the topic. Another fun fact: while the Thunderbolt 3 bus is indeed 40gbps, that's only filled out when video is used, the data speed is nerfed to 22gbps by all existing controllers. Dell admits this in one article https://www.dell.com/support/article/us/en/19/sln307875/thunderbolt-3-usb-c-maximum-data-transfer-rate-on-dell-systems?lang=en https://www.dell.com/support/article/us/en/19/sln307875/thun... > Thunderbolt 3 may only reach a maximum data transfer rate of around 7 to 22Gbps even though it is advertised with 40Gbps but this is so rare, every other article, even the one linked from this rare gem of truth claims some baloney like "Systems with 4 lane design will support up to 40gbps of data transfer over PCIe" which is obviously not true because even without nerfing PCIe 3.0 x4 is 32gbps only but it is nerfed. The official TB3 brief also tells you this but a little overt because it is never stated in the text but Figure 7 shows what's up in https://thunderbolttechnology.net/sites/default/files/Thunderbolt3_TechBrief_FINAL.pdf https://thunderbolttechnology.net/sites/default/files/Thunde... And make no mistake, there are only PCIe and DisplayPort signals on the TB3 bus, there are no USB signals, the TB3 controller in the dock provides a USB root hub. Someone should bring a class action lawsuit to Intel and practically all laptop makers for false advertising in this... (Side note: USB 4 will be different in the signals, if my understanding is correct then the Thunderbolt 3-like bus which is an optional mode for USB 4 will finally contain PCIe, DP and USB signals.)
