Picture not filling screen/no HD

[Brian010101]

My picture (non X1 service) isn't filling the screen, and the picture is not HD.  My TV's aspect ratio is the same as it always is--16:9.  When I watch a Bu-Ray disc, the picture fills the screen--same when I watch Netflix or use my Nintendo Switch.  The problem is cable, not my TV.

What cable box do you have? Is it connected with an HDMI cable?

It's a Motorola HD Dual Tuner DVR, about ten  years old.  It is connected to the TV with an HDMI cable.

Actually, I just switched to X1, so I'm getting new equipment.  Thanks!
