Peacock streaming problem with resolution

My system has been working properly since I subscribed to Xfinity about 4 years ago. I’m using their XG1v4 DVR. No changes have been made since then.

However when watching a Peacock program two days ago the screen when black but still had audio. A message on the screen said “Mode Not Supported, Resolution not supported…”

Pressing any button on the Xfinity remote did nothing. I unplugged the DVR from power, waited awhile & plugged back in. It rebooted & worked again.

Did some searching & it appears the screen message is generated from the Samsung TV when it receives an incorrect signal. However everyone that had a problem had it from the start, IOW when first connecting a device to the TV something was not configured properly.

I never have a problem watching live TV or doing other on demand streaming, and that includes today.

I’m presuming Xfinity is somehow corrupting Peacock & perhaps other streaming sources. Anyone else have this problem?

The problem is beyond Peacock. I was looking at Scheduled Recordings & the screen went black & displayed the message.

I have also been having issues streaming on Peacock and On Demand as well on the tv. I don’t have any issues with WiFi or at streaming on other devices.

user_793642 Thank you for reaching out! The message "Mode Not Supported, Resolution not supported" may occur if your X1 XG1v4 TV box is connected to an HDMI port that is not 4K compatible, or the TV Box may be set to the wrong resolution to play 4K content. Here is an article that may help with the settings for the X1 XG1v4 TV box.
