Is there a way to connect multiple monitor adapters in series (and then have a reasonable picture)?
Concrete:
a) HDMI -> DisplayPort -> DVI
or
b) DisplayPort -> HDMI -> DVI?
Explanation: I have a work laptop with HDMI connection and a private laptop with DisplayPort connection. My monitor only has a DVI connection.
It is a bit cumbersome to always screw the connector on and off to switch between HDMI to DVI and DisplayPort to DVI. It would be more practical if I had an adapter on one of the laptops so that both could use the same cable.
Since my HDMI-to-DVI cable broke recently (changed too often and therefore a cable break?), I would prefer variant a).
Thanks in advance!
(I already know solutions like "buy a second screen / use only a laptop".)
I personally "use" your variant a) because my screen is too old for my graphics card and I have no problems.
There are switches that enable switching.
E.g. 2X DVI to HDMI
or 2X VGA to DVI
Etc.
Series connection of the connections would not make sense. Because the pin assignment on the connectors is different between DVI and HDMI.
If only one switch would be considered.
e.g. 2 PC systems to one HDMI (monitor)
Multiple PC systems on one monitor are also possible (e.g. Splitter)
Why is the pin assignment no problem with a normal adapter for HDMI to DVI? What does it change if a DisplayPort cable is added? DisplayPort to DVI works without any problems.
But thanks, a switch also sounds like a good alternative. (Only that I would then unfortunately have one more cable lying around here…)
The problem here lies in the pin assignment itself. Like HDMI, DVI is also digital, but there are now devices that do not accept a pure cable connection and need a kind of converter for the transmission of the signals.
This also applies to Display Port to HDMI or DVI.
It becomes more problematic if you still use VGA. VGA are the signals analog not digital. A pure cable solution would not work here. You would have to interpose a converter that does this. There are also monitors that can process VGA digital signals, only these were very expensive at the time and there are very few of them. Most were often found in engineering offices or at developer stations.
