Unfortunately, I returned mine. Hardware is great with 120Hz but was not really happy with build quality and battery life (sure I could switch to 60hz but IF IT HAS 120 I WILL USE 120). Otherwise a pretty hot deal if you are looking for a budget laptop.

DisplayLink supports extend mode, this is the default setting for a DisplayLink display.

from https://support.displaylink.com/knowled ... on-windows

There are three configuration modes:
  1. Extend mode: This is the default setting for a DisplayLink display. The display is an extension of the Windows desktop, and will be extended to the right of the main display. Moving the mouse off the right hand side of the display will move it onto the extended screen.
  2. Mirror (also known as clone or duplicate) mode: The DisplayLink display mirrors the content of you main display. Note that in mirror mode, both displays must have the same resolution, which may not be optimal for the display. This can make the desktop look streched or scaled and there could be black borders around the image on the screen.
  3. Primary or Replace mode: The DisplayLink is the main Windows display. Replace mode extends primary mode by also disabling the laptop or tablet screen while connected to the DisplayLink device. This mode is used if wanting to use your laptop with the lid closed.

No, the HDMI 1.4 port does not support 4k 60 Hz output

The USB 3.2 Gen 1 Type-C port is only for data transfer

Yes, you can install a 2.5" SATA SDD

Instructions are in the service manual

Interesting, what's the catch? I guess the cost?

More costly, adds lag/latency and more CPU overhead (full screen 4k video)

thanks @Dhanushan for the reply, it looks Ryzen 5 5625U supports 4k @ 60hz, but dell doesn't build a port to use it in this laptop?

anyone has experience between 4k @ 30hz and 4k @ 60hz with movie watching and programming work? is the quality very different and is 30hz bad for health?

Are you sure it's the same laptop and your output is in 4K? On the Dell product page linked at the start of this page it pretty clearly says HDMI port only supports 1080p output.

AMD could be using this 'ol trick to support [email protected]

But @Dhanushan is right, technically the bandwidth of HDMI 1.4 cannot support [email protected] 4:4:4. If @musicalmd is truly running it at [email protected], it's running in 4:2:0 mode.

That's too bad, I'm using this laptop right now and love it! Yes I know the build quality isn't like a thinkpad but the price isn't like a thinkpad either! With the 15% rakuten cashback, this is HOT!

I think you are right. It's YUV 4:2:0. I used several laptops that supports HDMI 2.0 and don't notice any difference

This a budget laptop, Dell did some cost cutting by including a HDMI 1.4 port.

HDMI 1.4 has maximum video bandwidth of 8.16 Gbit/s (4096 × 2160 at 24 Hz, 3840 × 2160 at 24, 25, and 30 Hz, 2560 × 1440 at 60 Hz, or1920 × 1080 at 120 Hz)
HDMI 2.0 has a maximum video bandwidth of 14.4 Gbit/s. This enables HDMI 2.0 to carry 4K video at 60 Hz with 24 bit/px color depth.
from https://en.wikipedia.org/wiki/HDMI

30Hz refresh rate is not bad for health. 4K video quality will be reduced but would be okay from programming work.

Here's an excellent explanation: https://www.rtings.com/tv/learn/chroma-subsampling

TL;DR, it's a way to reduce the bandwidth required to transmit a video signal by subsampling (essentially, discarding some data). This may or may not be noticeable depending on your use case.
