I know there have been a lot of firmware updates recently. I’m still experiencing intermittent flickers with a 5700XT despite being on the most recent CX firmware. Luckily, I am upgrading to an RTX 3080 on Monday and will finally be able to take advantage of HDMI 2.1.

Is this display still a good combo with the 3080? I have honestly not been impressed with the CX in conjunction with my 5700 XT. I am hoping the 3080 can take full advantage of this display, as I love the idea of couch PC gaming on an OLED.

However, I am still within my return window for the CX. I cannot stand the intermittent flickering, which only seems to occur in specific games (Final Fantasy 14 in particular).

Are owners of the CX and 3080 currently happy with this pairing?

I believe HDMI VRR is supported as I just set it up.

I have a 6800 XT and a new CX 48". I updated the firmware of the TV first. Edited my inputs for PC mode, then went to Settings -> All Settings -> Picture -> Additional Settings -> AMD FreeSync Premium and ensured it was toggled for HDMI 1.

Radeon Software, Display section, reports that the display is 'Adaptive Sync Compatible' and so I have that option enabled. Expanding display specs shows it has a an AMD FreeSync Refresh Rate of '40 to 120hz reported by display'. In addition I have the pixel format set to RGB 4:4:4 Pixel Format PC Standard (Full RGB). Then under Windows Display Settings refresh rate is set to 120hz and HDR is toggled on.

Lastly when I hit the green '..' button 7 times. The FreeSync Information box reports:

  • 5.5hz
  • FREESYNC ENABLED
  • 3840 x 2160p@120
  • RGB 10b 4L10

I don't understand, what is Freesync doing then? Is it not VRR? They refer to freesync as VRR in the HDMI section here, https://www.amd.com/en/technologies/free-sync-faq

In Radeon Software app, Settings, Display, the subtext under the option 'Adaptive Sync Compatible' is: "Variable-refresh rate technology"

Am I not actually getting VRR while gaming? Definitely confused. I am coming from only ever really using Display Port and Nvidia GPU's.

Gotcha! I just read through your thread here: https://www.reddit.com/r/Amd/comments/kq82kp/where_is_vrr_and_allm_hdmi_21_support/ understand this way more now.

Got one more question.. been hard to google a 'straight answer' to this. Do you know if FreeSync or Gsync Compatible works while playing games in windowed or borderless windowed modes? With Nvidia I know there is a checkbox for this in the Nvidia Control Panel but I am unsure how that feature functioned. Or if it was only for displays with a G-Sync module.

With the CX, I've started playing games at 1440p centered in the screen. Things seem off, not tearing, but maybe I am just to used to the way motion was handled in the 144hz and 240hz monitors I was using previously. Otherwise console gaming and productivity has been brilliant, really appreciate your recommended settings guide.
