External display connection USB-C or Micro-HDMI?

[jj.cocker]

I just bought a new Dell Latitude 7370.

It only has a Micro HDMI port (+ 2xUSB-C and 1x USB-A), no no HDMI, etc.

I occasionally need to output to VGA or HDMI when connecting to projectors. Resolution up to 1920x1080 (or probably even less) should be fine.

Would it be better to go for a Micro HDMI -> VGA/HDMI adapter, or a USB-C -> VGA/HDMI adapter? and why? Would sound be supported with both?

I always carry a USB-C -> 3x USB-A hub, so don't really care if I lose one of the USB-C for the display, but ideally would rather use the micro HDMI if possible..

Many thanks in advance.

You want to make sure you use a microHDMI to HDMI cable, not an adapter if you want to make sure you get audio properly. Something like this would work fine: https/www.amazon.com/Fosmon-High-Speed-Support-Ethernet-Return/dp/B0117XEFXG

I have one of those, thanks.

What about one of these (or similar): https/www.amazon.co.uk/Adapter-UGREEN-Converter-Transfer-Zenbook/dp/B01ALGJS32

It will allow me to kill two birds with one stone...

You'll get audio through the HDMI output on that one.

...and what if I use the VGA output? No sound? VGA is the one I use the most, not HDMI.

VGA would not allow for sound output. You'd have to have the HDMI connected to the same system & set the VGA as the active display... then in sound properties set HDMI for the audio.

Also, is there any advantage in using the USB-C instead of the Micro HDMI (both with an adapter)?

 

[toshibitsu]

In this case, there would be no difference.

Excuse my ignorance, just trying to make sure I understand your answer...

- VGA does not support audio, so if I need to use VGA then either USB-C or micro HDMI will be fine (with no audio output).
- HDMI does support audio, so I can use either (C or micro)
- If I want to reserve the USB-C for other peripherals, then using the micro HDMI is probably a better idea.

In summary: there really is no difference between using either USB-C or micro HDMI to output either VGA or HDMI (via a suitable adapter).

Am I correct?
