Have TV Questions? Ask a TV Technician
Hi , I`m JackPerhaps I can help you with this problem but first a question , please bare with me even if it seems unrelated to the problem you have now ;
Do you have anything else connected to the tv and specifically a blueray player ?
what i`m getting at here is that your tv nor its hdmi cable have any bearing on the resolution , this has to do with your cable box and/or whatever is playing on the screen .
Was asking about a blueray as it will usually give you a 1080p resolution and i wanted you to see it for yourself.
Insert a disc in the blueray and pull up that info again while it is playing
Let me know what you get
This means that your att cable box is set at 720p resolution but mind you not all channels are HD and even less are 1080p , it usually goes around 10801 /720p but depending on your cable box it can also be upconverted to 1080p /60ps
This would have to be figured out with your cable company and the box model you have now
Again i will repeat , the tv has nothing to do with the resolution you see your show , it may be capable of the highest resolution but if you feed it a standard definition signal then thats what it will show you , it does not upconvert or modify anything ,its a monitor and show you what it gets fed in
For example my own cable box if let alone will give me the resolution of whatever is playing and the way it is broadcasted and as i said above this is mostly 1080i or 720p to save bandwith but if i disable these resolution in its menu then it is forced to come out 1080p .
This again depends on your box and its capabilities
Another ways to have a steady 1080p signal is to pass all your signals through a surround receiver that will process the video itself and always give you the same utput resolution no matter what the input .
I`m thinking for example the Denon AVR--S or AVR-X series of receivers
No that will not do it .
You need a full process receiver like the examples i gave you above but the easier yet is to have that box set or replaced if it cannot be set to output only 1080p
The problem is simply the cable box here , nothing else
Also , make sure you are watching a HD channel when you pull up that info
I`m sure , usually the clearer the tv can get the more you will see the defect of a low resolution signal .
If you cannot have the cable box sending a higher resolution then have att replace that box with one who can
Tell them that direct tv has receivers who can
That may do it !
No sorry , no can do , this will have to be done HDMI and from the cable box
