Its probaly becouse your signal from COX is not giving you 1080P.. your getting 1080i.. which is interlaced or in other words only half. this would explain the 60 hz. no cable company puts out 1080P yet.

AT&T has recently rolled out a bundled cable TV and high-speed Internet package in San Diego. Still in its infancy, AT&T U-verse is available in only 21 cities with a grand total of 30,000 subscribers. Nonetheless, it represents direct competition for Cox Communications and Time Warner Cable in San Diego. And when there is competition, consumers gain instant leverage. Below are some tips for using your AT&T U-verse leverage to get a better TV/Internet package, as well as a price comparison.

• You've got nothing to lose: Unlike cell phones, for the vast majority of cable TV/Internet packages, there is no termination fee (you could have a termination fee if you get DSL through your phone company). Usually, cable companies do not have to worry about consumers cancelling and going to a competitor, because there are no competitors. So, theoretically, if there were multiple providers, one could switch from company to company taking advantage of free trials without ever paying a penny (...that day may already be here for a lucky few).

• Let them know you are in demand: Happy with your service? Not happy with your current package? It doesn't really matter. Either way, you'll have an opportunity to get the same (or better) service for less. Granted, the San Diego AT&T U-verse rollout is not extensive at this point. However, AT&T has been very secretive about what specific areas are covered, and there is a good chance that Cox and Time Warner are in the dark with everyone else. So give your cable provider a call and tell them you're considering taking your service to AT&T U-verse and that you checked online and it said you were eligible (no matter what Cox or Time Warner tells you). Also let them know that AT&T is offering the first two months free on its 240 and 300 channel packages. They may say there is nothing they can do for you, but be persistent and see if you can't at least walk away with a couple of promo offers.

• Follow the freebies: If you are lucky enough to be in an AT&T U-verse service area, you may not have to pay for TV or Internet service for some time. Just like with cell phones, the good deals are offered for sign-ups and upgrades. Cox, Time Warner, and AT&T all offer sweet deals on either TV or Internet packages, or both. As mentioned above, you should not incur any termination fees for jumping from company to company to catch the next best deal.

REPLACE THE 2 CONVERGENCE I.C.'S PLEASE LET ME KNOW IF FIXED. THANKS,

Are you sure it's the TV and not the video source ? Have you tried other video sources ? You can also try to switch over to component cable. The red/green/blue colored cable. You only need HDMI for blu-ray to get the 1080p. If your TV is only 1080i then you don't even need to use HDMI. Also, some sources actually look better with a component cable compared to HDMI. Give it shot. 

Yes there is, at&t techs have issues with philips/magnavox. When you are programming these tv's, you will notice if u get the right code on this particular brand, the light on the tv will blink but not turn on. This is the correct code but, the simultaneous action wont work, you'll have to hit tv first by itself and then hit power. Don't know why, but it is what it is.

you can get a dvi/hdmi converter at target
