Using the USB 3.1 Gen 2 (10 Gbps) cable to connect laptop to ThinkPad USB-C Dock Gen 2 and then from the Docking station to connect through as well a USB 3.1 Gen 2 (10 Gbps) to a monitor that supports 120Hz.īy doing so, theoretically can one surpass the problem of the 1.4 HDMI limitation of data transfer mentioned above.
I'm thinking about the following scenario: connected through HDMI cable from HDMI 2.0 port of the Thinkpad docking station to the HDMI port of the monitor with 144 Hz at 1920 x 1080 p. port limitation of machine: Lenovo ThinkPad T590 (with UHD Graphics 620) -> 1.4 HDMI. Running on a laptop: Lenovo ThinkPad T590 - with UHD Graphics 620, connected then to a: ThinkPad USB-C Dock Gen 2 and then connecting a monitor with say 120Hz capability. desired result: connect & deliver higher refresh rate than 60 Hz connecting it with such a monitor at 1920 x 1080 p. Now my question from a different angle, is: what about the following scenario: "1080o 120 or 144Hz need a bandwidth of 7.46 Gbps or 8.96 Gbps respectively, so the bandwidth via HDMI is not enough. " he meant here the 1.4 HDMI
The reason I`m asking this again after reading Sebastian's answer from the link above, is, that he was stating: Could you please help out with the answer for the question from the topic title?Ī similar question was asked & Sebastian answered here, but I`m asking from a bit of a different angle.Ĭ/t5/Graphics/%C4%B0ntel-Hd-Graphics-620-120hz/m-p/1242212#M92978
