Product PhotoIt appears that LG C1 and G1 series OLED TVs made since September 2021 cannot play movies and games at 4K resolutions when connected to an external device, such as a 4K Blu-ray player or game system.

From what we could find, reports started hitting various online discussions around mid-October that people were having problems playing 4K Ultra HD Blu-ray discs and gaming at 4K on the Xbox Series X, PlayStation 5, etc.

While the company deflected those first problem reports, enough complaints must have come in, and it is now saying that a firmware fix is coming. Based on multiple reports, it sounds as though the HDMI chipset used by LG since September is not HDCP 2.2 compliant, which causes external devices to default to HD playback instead of 4K.

TV reviewer Vincent Teoh mentioned on his Twitter feed recently that LG recognizes the issue and a software update will be available "in the coming weeks."

He released a video on his YouTube channel today that talks about the issue in a little more depth:

Fix Forthcoming Released!

Some unconfirmed reports are saying that the fix will be available on November 17, 2021. We'll provide an update if/when a fix becomes available.

Update: LG released new firmware on November 17, 2021 as expected. Those applying the 03.20.80 firmware on AVS Forum (see link for discussion below) have reported success with overcoming the problem. The release notes for the new firmware just lists "Fixing minor bugs in software" which seems to be understating the issue quite a bit, but I guess "fixes our 4K TVs so they play stuff in 4K" was unacceptable.

Vincent Teoh just released a followup video, which you can view below:

In the Meantime...

4K playback works via the onboard apps in the TVs, and external devices will play at HD resolutions, but that's likely not why you bought a 4K TV and 4K-capable devices. Here's hoping LG issues the fix soon, and it does right by customers who purchased its high-end televisions.

There are great prices happening right now on these TVs, which makes this news pretty disappointing. How can one have confidence buying an expensive TV when it has an issue that prevents it from performing its primary task?

We recommend finding a TV with a build date before September 2021 or purchasing from a vendor with a good return policy in case this doesn't get fixed in a reasonable amount of time.

Another alternative is to look at the Sony A80J and Sony A90J OLED TV series, which is considered highly by reviewers (and better for movies by some than the LG series, which is judged to be slightly better at gaming). The prices are comparable to the LG, and might be a better choice, depending on your situation.
