No, they can be very different. USB‐C contains three components:
• Data transfer: data speeds can vary from 480Mbps (USB 2.0) to 10Gbps (USB 3.1 Gen 2)
• Power Delivery: laptops may or may not support power delivery. If USB‐C power delivery is not supported, a traditional laptop power tip is going to be needed to charge the device.
• Video support: may or may not be implemented by the host device manufacturer (as they may continue to use DisplayPort, HDMI, or VGA ports for video capability)
For traditional UtechSmart USB C HUB / Docking Station, USB‐A supports data transmission only, while USB‐C may support video, power delivery, and data. A USB‐C to USB‐A adapter will support data transfer, but the video and power delivery features of USB‐C will not work.
For Latest UtechSmart DisplayLink USB C Docking Station, it can also support those devices which only have a USB Type-A port(after updating/downloading DisplayLink Driver). Shockingly, it can provide quadruple displays using MST (Multi-Stream Transport) for both macOS & Windows laptops.
Please do not worry. This usb c hub supports 4K@30Hz HDMI OUTPUT (depends on your HDMI cable and monitors). If you connect VGA, the resolution of all monitors will be limited to 1920 x 1080@60Hz (maximum).
In normal, when you connect 3 monitors, all of three monitor will output 1080P resolution. However, it may happen that one of the monitor screen resolution is lower than 1920 x 1080@60Hz (depending on the monitor and bandwidth).
Yes, it can. Please make sure your laptop, hdmi cable and monitors support 4K.
If you connect VGA, the resolution of all monitors will be limited to 1920 x 1080@60Hz (maximum). When you connect 3 monitors, it may happen that one of the monitor screen resolution is lower than 1920 x 1080@60Hz (depending on the monitor and bandwidth).
The USB C Hub supports video outputs with 1080P / 60Hz and 4K / 30Hz.
1) Please check whether your 3 external displays support 4K resolution. If the laptop supports 4K but the display does not support 4K, it will not extend the 4K resolution of the laptop;
2) If the VGA port uses a 1080p display, in the duplicate mode, it will pull down other displays to 1080p;
3) If you are using a Windows laptop, please go to
https://www.intel.com/content/www/us/en/products/docs/graphics/graphics-command-center.html to download Intel graphics command center.
Here, you can clearly see the default resolution of your laptop's graphics card. And it will automatically make a decision that best suits its output resolution.
4) If you want the external monitor to achieve a higher resolution, you can adjust it manually. I have attached a picture for you to guide you through the setup operation. But if you are here, you still cannot set a higher resolution, either your laptop does not support the external display to reach a higher resolution when multi-screen expansion or your external display does not support a higher resolution Resolution.
