I have one notebook; a Huawei MateBook D15 i3 2021 and one monitor; an Acer VG240YSbmiipx 23.8" IPS FHD 165Hz.

If I want to connect the notebook to the monitor through the HDMI or DisplayPort cable/adaptor, which HDMI or DisplayPort versions are suitable?

 

My Laptop Details

Processor model: i3-10110U

Driver version: For the Processor: 10.0.22621 Build 22621/ For the Intel(R) UHD Graphic: 27.20.100.8984

Windows version: Windows 11 Home Single Langauge 64-bit (10.0, Build 22621)

Bios version: Huawei 1.45

 

Many Thanks!

Your processor supports HDMI 1.4a and DisplayPort 1.2.

If the processor is directly connected to an HDMI port, it is capable - provided a high enough quality cable is utilized (I recommend one at least HDMI 2.0 compliant) - of supporting only 4K@30Hz. Note that some laptops limit the external display resolution to that of the embedded display; you need to determine if this is the case with your laptop.

If the processor is directly connected to a DisplayPort port or indirectly connected via a USB-C or Thunderbolt port), it is capable - provided a high enough quality cable is utilized - of supporting 4K@60Hz. With a high-quality DisplayPort-to-HDMI adapter/cable, HDMI 2.0 can be utilized and thus 4K@60Hz can be achieved. The 'but' here is that this output is not quite 100% compliant with the HDMI 2.0 specification and thus some features are not supported (this doesn't mean monitors won't work, however).

In premium quality laptops (and PCs), a DisplayPort signal may be routed through a LSPcon chip that will convert the output signal to HDMI 2.0. In these laptops, a 4K@60Hz HDMI connection can thus be achieved - and this connection is 100% compliant and capable of utilizing all HDMI 2.0 capabilities. Again, though, this is only a feature of premium laptops and it doesn't sound like your laptop fall into this category.

If your laptop does not have a DisplayPort port and it does not have a USB-C or Thunderbolt port supporting DisplayPort output, you have to be careful what adapter you utilize to convert the signal from a HDMI port to support a DisplayPort monitor. Both HDMI and DisplayPort are one-way connections and thus you cannot turn an adapter around and use it to go the other way. You must specifically have a HDMI-to-DisplayPort adapter. Be very careful determining how a specific adapter can be used.

Ok, last but not least, I have to discuss USB-C ports. If a USB-C port is supporting only a display, the 4K@60Hz capability is supported. But - and this is a big 'but' - if it is a DisplayPort monitor that offers a USB hub or you are connecting a USB-C hub device or to a docking station, then the DisplayPort signal throughput will be halved. This means that only 4K@30Hz will be achievable.

Hope this helps and hasn't confused you too much,

P.S. There is lots of good information in Wikipedia pages https://en.wikipedia.org/wiki/DisplayPorthttps://en.wikipedia.org/wiki/HDMI and https://en.wikipedia.org/wiki/USB-C - including tables that allow you to roughly determine what other resolutions can be utilized where (again, I recommend all cables be high-quality, HDMI 2.0 or DisplayPort 1.4 compliant).
