According to our information, the product is intended for Lenovo products.

Yes, I use it for Dell laptop and Lenovo with 3 screens. If you only want to connect 2 screens, a cheaper docking station from Lenovo is also sufficient.

Yes, the DisplayPorts are 1.4. You can use both simultaneously. :) As for the resolution, it depends more on your computer and its graphics card.

Hello serik_jur We had the problem with some Lenovo notebooks that they did not charge at all with a 135W power supply (but the other functions worked). According to the manual, there are two ways to connect notebooks to the docking (see here https://download.lenovo.com/consumer/options/thinkpad_thunderbolt3_specific_poster.pdf). However, additional adapters are required for this (not included in the scope of delivery). I can also see from the technical data that the charging power is 65W, but I don't know whether this depends on the connection type. Maybe just try it? :-) LG

We enquired about this with the manufacturer and received the following answer. The Thunderbolt firmware in this dock can only be updated via a connected notebook. Make sure the dock cable is connected to the correct Thunderbolt Type-C port when updating the dock firmware. For the dock to perform at its full potential and enable the data transfer rates of Thunderbolt™ 3 technology (up to 40 Gbps), it must be used with a Thunderbolt™ 3 enabled system. If it is connected to a system that supports it but does not have Thunderbolt™ 3 enabled (see list of supported systems), it can only operate at the speed allowed by that system. For example, if the dock is connected to a system that only supports a USB3.1 Gen 2 connection but not Thunderbolt™ technology, the data transfer rate will only be up to 10 Gbps. The performance of the dock depends on the hardware and software used and many other factors. The actual data transfer rate may be slower than intended for corresponding connection technologies such as Thunderbolt™ 3 or USB3.1.

Via USB C. My Dell PC has a Thunderbolt port. If the Dell laptop is old, I would do without this docking station.... Other Lenivo docking stations are not compatible with Dell.

However, this is due to your laptop or the cable and not this docking station. Both my devices (Lenovo L13 Yoga 20R6S06E00 & Lenovo T480s 20L7-001NMZ) get power/image/audio/input devices/etc. via Thunderbolt.

According to research, it is only compatible for the L480 of the L series.

Unfortunately no. This docking station is compatible with several Lenovo Thinkpads.

There is a jack cable port, however, it did not work for me to listen to music or communicate.

Lenovo says: Lenovo USB-C and Thunderbolt docks are compatible with laptops that support USB-C Alt-Mode or Thunderbolt protocols through their USB-C port and require up to 65W of power charging. If your device supports these protocols, it should be fine.
