I am searching a cable which i can connect with my RX5700XT via Displayport to my monitor with HDMI and a resolution of 2560×1080 pixels, running at 75HZ. I can only find DP-to-HDMI cables for 4k @60HZ.

HI Elperdano,

The CAC-1073 can do what you ask.

First thanks for that quick reply.

But when i also want Free-Sync and HDR? Does it also work with the CAC-1073?

Hi Elperdano,

No It does not support Free-Sync. You might need to use the CAC-1080 with a propper HDMI 2.0 cable.

But let me try and help you, what Display are you using? Not every FreeSync Display supports FreeSync of HDMI.

Hey Baak,

its the LG 29WL

OK, so the screen only has HDMI. It must be supported over those ports then.

I would suggest you to get the CAC-1080 + CAC-1310. If you really want to go from DP to HDMI.

But why not just go from HDMI to HDMI with the CAC-1310?

The problem with HDIM->HDIM is that the GPU detects the other monitor (currently connected via DP->HDIM as the main Display, because the GPU prefers the Display connectet to the DP. But I want my LG as my main Display. The reason for that is, that in Games i wanna play with 75HZ and when i set the Game to “Borderless WIndow” it syncs with the 60HZ from the “main” Display.

You can set a main display in the Windows settings. Or am I thinking to simple?

I’ve don this, but when I start the PC i see my Bios Settings on the Second screen which indicates that the Gpu prefers this Display. So the Display settings are just for windows and not for the Gpu i guess.

Is your LG 29WL set to 144Hz in Windows actually?

Right click on desktop

Display Settings

Scroll down

Advanced display settings

Display adapter properties for Display1 (or 2 depending)

then select Monitor

Screen refresh rate set it to 144Hertz

This should solve the borderless window issue.

I set it to 75HZ, but it doesn’t fix the problem

Well then you have to try the CAC-1080. With a HDMI 2.0 cable. Otherwise I don’t know anymore.

There aren’t any DisplayPort to HDMI adapters that support FreeSync or G-Sync or Variable Refresh Rate, is there? Only HDMI 2.1 displays can support that? No-one makes a DisplayPort to HDMI 2.1 adapter that support Variable Refresh Rate.
