@scouternorm If you are asking how to set the output resolution manually on the Xi6, the option is in: Settings > Device Settings > Video Display > Video Output Resolution
You can also set the output resolution directly with the following sequence: Press and hold the "Rogers" menu button for three seconds, then key in: ⬆️ ⬆️ 2. You'll see a pop-up that says: "Enter Control Code"; enter the desired resolution. (e.g. 0720 / 1080) Easter egg: 7777 displays the screen saver.

Ignite box hooked to RCA 4K making screen green, with no sound & 1280x720P. This issue first showed up last Sunday. At the time, I restarted the box, changed HDMI cable, and even changed HDMI ports, all to no avail. Then I grabbed another box from another TV, hooked it up & it worked fine. I even took the faulty box to the other TV, & it worked fine there. I contacted Rogers & they sent a tech on Monday, who replaced the Xi6-A with another brand, model Xi6-T. At that time, all worked well. A few hours later, it reverted to the green screen of death. lol I tried bringing another box to the TV, like the first time, but this time it didn't fix it. When the tech was here, he said that this was an issue that other techs had ran into, specifically with RCA 4K tv's. & the contact at Rogers Facebook page said it was also a known issue, but no fix yet. I suspect that a software update is the culprit, as my RCA tv worked fine from when I had Ignite installed on Dec 31/19.
Has anyone else experienced this issue?
1. Have you gone into the Rogers box' video settings and set the video output to 4K instead of "auto"? Have you tried 1080i just as a test?
2. Make sure you're connected to the 4K HDMI port on the TV. Some TVs only have one specific port for 4K.
3. Have you updated the firmware of the TV? Sometimes it's not compatible with Rogers' boxes until updated.
@scouternorm Okay but assuming that this problem was caused by a Comcast software update, Rogers didn't write the code that broke things for you so all that they can do is inform Comcast of the interoperability issue with your TV.
It's also equally possible that RCA may have updated their firmware (to fix broken behaviour) and the Xi6 update fixed an interoperability issue with that update for your TV, which you have not applied yet.
In the end, it will be easier for Rogers to escalate getting a fix (assuming that one is required) if your TV's firmware is up to date. Your other course of action is to call RCA for support to see if this is a known issue that they are working on fixing... and I'm sure that they, too, will ask if your TV's firmware is up to date as well.
