How to connect 2x 4K120 displays (HDMI only) to GPU with only one HDMI port?

I have a NVIDIA GeForce RTX 3080 Founders Edition, which has 1x HDMI port, 3x DisplayPort.

Until recently, I had a:

LG 4K144 OLED TV (HDMI only) plugged into the HDMI report
TCL 4K60 LCD TV (HDMI only) plugged via DisplayPort using the Plugable DisplayPort to HDMI active adapter

This worked fine but I am now replacing the TCL LCD with an LG 4K120 OLED TV, but the Plugable active adapter supports only 4K60.

Any idea how I can connect the second LG display to a GPU that has no HDMI ports left (only 3x DisplayPort) and still run at 4K120?

Can’t you just buy a display port to HDMI adaptor that supports 4K@120hz ?

Or don’t these adaptors actually work :confused:

Given that this will be a non-gaming monitor, can you plug it into a second GPU?

I guess that is partly my question; is basically what I already have (the active adapter), but one that supports 4K120, what I need

Think you would need a DP 1.4 to HDMI 2.1 adapter or cable.

Tv would need to support hdmi 2.1 on the port you are using too.
