LG CI OLED TV and Foxtel Ultra HD (4K)

November 21, 2021

Another blog post for future me… and for anyone else in this situation.

I’d heard about a bug in LG C1 OLED TVs made from Sept 2021 that didn’t allow 4K content to play in 4K (see https://www.youtube.com/watch?v=ifkarBLgnWw). The gamers were up in arms. But as I’m not a gamer, I didn’t think it applied to me. However, I do have Foxtel and an IQ4 box, which is designed for 4K/ultra HD. So I checked if I could play a 4K movie from the dedicated Foxtel channel for these. Nope. I got an error message that my TV was incompatible (error F0446, details and troubleshooting here: https://www.foxtel.com.au/support/technical-support/error-code-troubleshooting/iq4/f0446.html). So I waited for the software update to roll out from LG and tried again. I still got the same error message.

I went back to Vincent Teoh’s original video (Vincent is just awesome, and funny too!) and found he had created a new one just for the bug fix (https://www.youtube.com/watch?v=GI-ebazGJ4I), where he said you may have to change a couple of other things on your TV too. I tried those but still kept getting 4K error message on Foxtel. Based on previous experiences I really didn’t want to call Foxtel support…

So I went back to Foxtel’s troubleshooting pages for this error and stared working my way through the suggested solutions. Some I just couldn’t do on my TV as I couldn’t find the relevant settings. But there were also some suggested changes to the Foxtel IQ4 box you could make through Advanced Settings, and it was there I found the solution under their Step 3 (https://www.foxtel.com.au/support/technical-support/error-code-troubleshooting/iq4/f0446/connected-to-tv.html).

My picture settings were set to 1080p, so I changed it to 2160p (as per Step 3) and as soon as I did, I could view the ultra HD Foxtel channels!
