¿How to choose the right adapter?….

Hello everyone. 

I need an adapter to connect my computer to my monitor. The port on my computer is a DisplayPort and it has the following label next to it: “DP++.”

The port on my monitor is HDMI.

Out of your full range of adapters, how do I know which one would work in my case?

My monitor is an Acer B273HU, and my computer is an HP Z230 with Windows 10 Pro.

I know they are very old devices, but they still work well for the tasks I do.

DP++ means DisplayPort Dual Mode which means you can use passive (requires DP++) DisplayPort to HDMI adapters. Passive means the DisplayPort port can output an HDMI signal and all the adapter has to do is change the voltage.

DP++ is usually limited to 4K30 or 1440p60.

Of course, you could also use an active DisplayPort to HDMI adapter. Active means that it converts DisplayPort protocol to HDMI.

The B273HU is only 2048 x 1152 62Hz. I think that resolution only requires HDMI 1.0 so it should be able to work with any DisplayPort to DVI or HDMI adapter.

HDMI 1.0 is limited to 1920 x 1200 60Hz.
HDMI 1.4 is limited to 4K30 or 2560 x 1600 60Hz.
HDMI 2.0 is limited to 4K60.
HDMI 2.1 is limited to 4K120, 8K30, maybe 4K240, 8K60.

Each version can support all the older versions.

You may want a newer adapter if you want to use it with a newer computer and display in the future.
