The tv *is* HD, and capable of 1080i resolution on the component inputs. If you want to watch local broadcast stations in HD though, you will need a separate component from your cable or satellite company, OR you can buy used digital tuners from ebay for quite cheap. You can also watch HD DVDs and Blu-Rays using the component inputs.

Re: can i upgrade to hd on this tv
I am not finding anything on the net about being able to upgrade it but the HD in the model # stands for high def but the tv is old enough that it may not go up as high as 1080 most likely just 480i or p which can be achieved with an s-video or might be 720 with the R/B/G connector or a DVI connector, you can look for converting cables on ebay

I dont know about your particular hd hookup , but I take the hdmi cable out of my dish reciever/dvr [digital video recorder] and run it straight to the hdmi input #2 in the back of my apex 40 in lcd-hd-tv
I think take the hdmi output from the at&t u-verse cable box and plug it into the hdmi input of your 70 in sharp smart tv
that will get the input signal from your cable box ,both video & audio, into your tv set. on the back of your tv set there should be audio outputs for home theater audio systems that would plug into the audio inputs of the home theater system.
prehaps i am wrong because you say that your yamaha is a home theater* reciever.* is the yahama more than a home theater audio system? What does it recieve?
Idea-- the salesman that you bought it from should be willing to help tell you how to hook it up.
also consider that there are many different ways to hook up vcr's and then dv recorders and dvd recorders and external 2 tera bite hard drives into my tv & dvr . I got that all hooked in & a rats nest of wires. so i can record in hd or sd,on vhs or dvd or dvr point is that you cant hurt anything by plugging the wrong plug into the wrong jack, as long as the same type of plug goes into the same type of jack. If its right,it works, if its wrong, it wont work until you plug it into the proper jack.
im sorry ,im 65 am not into knowing all the latest and greatest cutting edge tech ,but i am begining to catch up on my hobby, movie recording tech.
The Gateway GTW-P42M303 can display HD content. However, you will need a set-top box to get that content. The TV only has an analog tuner (NTSC or PAL, depending on the area where you purchased the TV). Thus, you will need to connect a digital-to-analog converter to get most over-the-air stations. (Only low power stations are still broadcasting in analog.) Most of the common d-t-a converters only provided SD (480i) output. There are some HD tuner boxes available; you may have a hard time finding them.
If you have cable or satellite service, then you can get the HD programming package and view it on this TV.
make sure your tv is set in right language and location because after the big re-tune you might of entered wrong ones
the best way to do this is reset back to plug & play put tv in analog mode press TV/DTV on remote and then MENU ( NOT DTV MENU ) move down until you see plug & play in one of the menues press enter and follow on screen instructions
Basically I'd done everything right, as I thought I had, but something told me to use "system restore" and try again. I did, and everything worked. Thinking back, I'd recently downloaded an update for my my computer which included a sound upgrade. Job done; thanks anyway for this useful and helpful site.
Unfortunately, at this time, you don't unless it is a powerful station local to you. In order to see which stations are available to you, you would enter the Setup menu of your tv, and then the section that allows you to scan for channels. Also, digital cable alone doesn't guarantee you'll get HD signal. You would have to order an HD package from your cable or satellite provider. For example, Comcast touts their digital package as if it were vastly superior to the "standard" signal. Whether or not it is would be a matter of opinion, but the digital package is not HDTV. This misconception has disappointed many a subscriber, myself included (until I ordered the HD package). :^ )
Which network? Cable? Satellite? Dish or Direct?
With any of these providers, you should get an ATSC or "digital" signal. If not, the problem would most likely be with the service provider since they are converting the signal for you. The only way that your set would be affected is if you have an "off air" (antenna) signal only. At this point you would need a converter box. If your service provider is providing you with a HD receiver, then you should have no problem recieving HD (as long as your paying for HD). However, keep in mind, digital is NOT HD. If there is an incompatability with your receiver, check with your service provider for a software or hardware upgrade. Also, check with your local TV serviceman to find out if there are any software upgrades (firmware) for your TV. Being three or so years old, it is possible.
One last thing to check is to see what type of signal you are passing from your providers box to your TV (which type of cable". At a minimum, you need a "component" connection to pass HD content. A "composite" signal is standard definition. Best you can get right now is an HDMI cable. Best "one cable" source for video and audio.
To have HD on cable, you will need an HD cable box with the HD service activated by the cable company. Some cable carriers will provide some basic HD services included in the base cost with the box.
From the HD cable box to the TV, you will need an HDMI cable between the cable box and the TV set. This is an HDTV interconnect wire. You will have to refer to the instructions on the cable box and on the TV to get everything going properly.
