We frequently have the TV picture interrupted and the screen displays " STB Refsw design". We have HDMI cables, two TV sets, different manufacturers, happens on both.
We have reset the router several times.
What / where is the problem??.
Solved! Go to Solution.
The message is due to the fact that your TV is "refreshing" the display resolution based on the programming it's getting. Which happens quite frequently if you are changing from HD channels to standard channels.
There are tons of possible solutions for this and a quick google search will give you ideas.
One thing you can check is to see if the cable box is set to HD.
With the cable box and TV on
Use the comcast remote and press the CABLE button at the top and then the POWER button to turn the box off (but leave the TV on)
Then press the MENU within 5 seconds
This will bring up the display settings menu
YPBR/HDMI should be 720p
4:3 Override should be 480p
Use the arrow keys to adjust
All other settings are optional and won't effect resolution.
Then press the power button again to save this and turn the box back on and test.
This is for HD DIGITAL boxes only. Our HD DTA (real tiny black boxes with no guide or on demand) have a different menu that can be accessed thru the XFINITY button.
EDIT: FYI - There are very very very few stations that broadcast in true 1080 due to cost. Though you can set boxes to 1080i/p, you're box will adjust to the channels resolution only which is normally 720p. Setting to 1080i or 1080p## will cause similar results as you are already having.
How do you restart with the x1 controller? Im getting STB refsw design on my TV and my screen is black.
If you have a black screen, you cannot access the Settings on the X1 platform to restart. In this case, pull power cord from the outlet and let it sit for 10 seconds and then plug back in. This is a restart of the box.
