I have a single display port on my HP laptop. Currently, I have a
DisplayPort -> HDMI adaptor plugged into it that works perfectly and gives me fantastic 3840 x 2160 resolution on my 4k monitor.
However, I have been having a devil of a time getting a second external monitor to work. The best I can do is
USB -> HDMI or
VGA -> HDMI, but this results in super poor quality, fuzzy 1920x1080 resoluiton on the second 4k monitor. (And with the VGA adaptor, the second monitor frequently blacks out for a few seconds.)
There are DisplayPort to Dual HDMI splitters, like this one, but they all come with warnings like:
This will work as long as the DisplayPort on your PC will support MST. Please check the specification of your PC (due to the customization) to be sure before purchasing this item.
Or this one, which warns:
✔ IMPORTANT NOTES – 1) DisplayPort 1.2 GPU/Graphics card required
So, I have been trying to figure out if my laptop will be compatible with these devices.
Device Manage > Display Adaptors I have:
Fresco Logic is the
USB -> HDMI adaptor that is giving poor resolution on the second external monitor. And I don't know enough about hardware to know which of the other two is the display port. I have googled both of them, but I can't make any sense of what I am reading about them.
What should I be looking for?
I found this about the
Intel(r) HD GRaphics 520, which states:
The revised video engine now decodes H.265/HEVC completely in hardware and thereby much more efficiently than before. Displays can be connected via DP 1.2 / eDP 1.3 (max. 3840 x 2160 @ 60 Hz), whereas HDMI is limited to the older version 1.4a (max. 3840 x 2160 @ 30 Hz). However, HDMI 2.0 can be added using a DisplayPort converter. Up to three displays can be controlled simultaneously.
So... should I be good?
