Advice on laptop with USB-C port and USB-Type C Multipoint Adapter (and VGA)
Advice on laptop with USB-C port and USB-Type C Multipoint Adapter
Background: a few months ago, I bought a generic / inexpensive USB-Type C
Multipoint Adapter (with VGA output) and around the same time ordered a laptop
that advertised a USB-C port. When I received the laptop, I saw that it did
not have the USB-C port, so I returned it. I kept the USB-Type C Multipoint
Adapter. I also started digging into the USB-Type C port and learned that
there are several variations -- some that support video and some that do not.
(I guess a key thing is USB-C "alternate mode" which, iiuc, under some
variations, can support video -- I strongly suspect that not all
implementations of alternate-mode support video, and even less so, all
variations of video.)
Yesterday, I almost bought a HP Pavilion Laptop model 15z-eh000, but was
uncertain it would work the way I wanted, and today the price has gone back up
by $120, so I'm not anxious to buy it atm. But, I want to understand more so
that when I find a laptop that I want to buy I can confirm that it meets my
needs.
My needs:
* first, I want to hook it up to my KVM switch (with two other computers),
install Buster on it (and C++ version 20 (or whatever they call it)) and use
it for development of a lexer for Scintilla.
* second, as a laptop, I expect on rare occasions to disconnect it from my
KVM switch to use it portably
Other information:
The KVM switch has VGA input and output, and the Multipoint adapter has USB-C
input and, among other things, a VGA output (and RJ-45 for Ethernet, bbut no
HDMI, which would be irrelevant anyway in view of the KVM switch and my VGA
monitor).
Below I quote some information from various web pages I looked at with respect
to the HP 15z-eh000, and here is the "specification" for the (2) USB-C ports:
"1 SuperSpeed USB Type-C® 10Gbps signaling rate (USB Power Delivery,
DisplayPort™ 1.4, HDMI 1.4, HP Sleep and Charge)(with AMD Athlon™ Gold
processor);"
So, (some of) my questions:
Would that laptop work with Buster and my Multiport adapter with VGA adapter?
Does Buster support DisplayPort? (Do I need to have DisplayPort supported?)
If I had a multiport adapter with HDMI output would it work with that laptop?
(Not that that would work with my KVM switch, but it provides a little extra
information to me, and I could consider an HDMI to VGA adapter in the
"chain".)
Thanks for any input! Extra credit if you can claim experience with actual
devices ;-)
