Your TV's highest resution is 720p. Can't go higher than what the TV was built for.

Change the settings on your HDMI output to 720 progressive for resolution. The tv likely cannot handle the 1080 resolution, or the tv can only use interlaced (1080i or 720i) format.

I have a Mitsubishi WD-73737 73-Inch, the picture format keeps changing automatically. for example, the format will be set at 720i wide and it switches back and forth to 720i normal. any ideas?


I've seen that happen on equipment that has automatic signal detection. Usually this option is available when connecting the equipment with an hdmi cable. The setting can either be on the television or the cable/sat box or both. You have to disable the automatic signal detection signal on both the television (if the television has one in the setup hdmi menu if there is one) and on the cable/sat box. Further you have to choose a resolution on the cable/sat box normally 1080i or 720p fixed. Disable the 4:3 override if there is one. Save and lock in the settings and you should be all set.

We have bought a Panasonic Viera 32 which was a display model and we cannot get the hd and the picture to be set up. How can we start again?


1. Before we begin: First you need an HD source (HD Cable, Blu-Ray Player, HD Media Player) and HDMI cables in order to receive HD signals. HDMI cables look like this:

captainhawk1_4.jpg
Do not buy them in a store, they will only rip you off and despite what the salesman will tell you, all HDMI cables are EXACTLY the same regardless of price and no, gold-plating does nothing to improve a signal. Digital signals are ones and zero's and are not subject to degradation that analog signals are. I would recommend going to Monoprice for all of your cabling needs and get at least a six-foot HDMI cable.
http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10240
If you are cable or satellite subscriber, please note that you MUST HAVE an HD Receiver, Convertor Box or DVR. If you were previously using a cable box, DVR or satellite receiver on a standard definition television, it WILL NOT receive HD signals and therefore you will not have an HD picture on your TV. Also, an upconverting/upscaling DVD player is not an HD source. DVD's are in SD and depsite the fact that they are upscaled, you cannot change the fact that they are recorded in SD and will display in SD on your screen despite that your TV will tell you that you are viewing a 720p (HD) picture. it will certainly look better than a non-upconverted/upscaled DVD but it won't be HD and you'll be able to tell the difference with HD Cable and Blu-Ray.
The only two ways to get HD channels without HDMI is by getting them over the air, and directly through your coaxial cable from your cable provider without the use of the box, however, not all Cable companies send the signal to be converted by the digital tuner in your television and if they do, they do not support it in their terms of service so if they stop working, you're out of luck. Also, whereas the your local provider may offer 50 -100 channels in HD through their HD Converter or DVR you will only be able to get the five major networks and Univision through the coaxial feed. The same goes for over the air HD signals via an antenna.
2. Connections: I'm proceeding from the premise that you have an HD source as described above with HDMI-Out ports. With your TV powered on and your HD Source powered on, connect one end of the HDMI cable to your HD source and the other end to one of the two HDMI-In ports on the back of your TV (your choice). Because it's an HDMI interface, the television will automatically detect the incoming HD source, turn on the HDMI port of the TV and set the resolution accordingly to the HD Source.
Keep in mind that as this a 16:9 Aspect Ratio display, some shows may still show up in the old 4:3 ratio with black bars on the sides of the picture (also, SD Channels will not appear in HD). This is completely normal and for the best viewing experience possble you should keep the black bars and not "stretch" or "zoom in" on those programs as doing this, despite filling your screen. will distort the images and just make them... well... ugly.
NOTE: If your HD source is a cable box, DVR or satellite receiver, you may have to go into the settings menu and into the Audio Menu of those units and set the audio to "HDMI-Out." Again, this should automatically happen when the connection is made but if you have no audio, that's the solution. Also, in the settings menu you will find the video menu and in that video menu you may find a resolution menu with a list of the different resolutions that the box/DVR will display (480i, 480p, 720i, 720p, 1080i). Uncheck all of them except for 720p (as that is your TV's maximum display resolution). If you don't, every time you change channels from a channel that displays in one resolution to a channel that displays in another, there can be a delay of up to 30 seconds. By keeping your resolution constant there is no delay when changing channels and the lower resolution channels are simply upconverted to 720p.
Your connections are now complete and you now have HD and are ready to go.
3. Some Final Thoughts: First, please keep in mind that your television has a maximum resolution display of 720p which means that Blu-Ray (1080p) and 1080i signals will be downgraded automatically for your TV. I want you to be aware of this just so you understand that even though you may have higher resolution sources, your TV's capability is what it is so don't be concerned if you are watching a Blu-Ray and your TV indicate that it's in 720p. The fact is that for any display under 40", you don't need anything above 720p as the screen size is too small for your eyes to see a difference. I personally have a 32" 720p Vizio and a 65" 1080p Mitsubishi and the Vizio looks great in 720p.
Here's the link to the manual and firmware updates for your set as well. Download the software updates to a USB Flash Drive, insert it into the USB port on your TV and follow the instructions.

Lastly, I highly recommend you getting a Blu-Ray calibration disc with color filters for your TV (if you don't plan on getting Blu-Ray then get the DVD). They are about $20 on Amazon and though they take about an hour to get the hang of, they will help you achieve the absolute best picture possible for your new TV. TV's are preset with settings to make them pop-out in store displays and they are not optimal for home viewing. I waited a year to get one for my 65" and when I did it was like I got a brand new TV. The difference is outstanding and it's a small investment to make for what a professional will charge $200 - $300 to do. Here's a link for both DVD and Blu-Ray calibration discs.

Hi My LG 52LB9DF tv is slightly blurry - I'm not sure if it's the size or quality of the tv? Even the HD channels are slightly pixellated. My friend has a smaller tv with a much sharper resolution....


1. Your TV has a digital tuner built-in, you do not need a set-top box to receive local digital channels.

2. Try to disconnect the box, hook up the antenna directly to the TV antenna input & program the tuner, you may getting better picture.

How to hook up to hd tv


Use the highest resolution connection your HD TV will allow. This will usually DR570's HDMI connector. Most all digital video devices have one or more. The DR570 has an HDMI OUT. Connect it to any HDMI IN connector on your TV. You will then need to set the TV's Input selection to the Input Number you connected the DR570 to. See your TV Remote or Manual.

The DR570 has three types of output connection options, in order of quality; HDMI, Component(Red/Blu/Grn RCA jacks), S-Video (circular connector), and composite (Red/Wht/Yel, where Yel is video and Red/Wht are left/right stereo audio). Red/Wht RCA Audio jack connections are required to be made on all Output types excepting HDMI.

Note, to get your Digital channels, you will need to toggle the DR570's DTV/TV button. DTV is Digital TV channels. TV is analog channels, the DR570 found on your Cable or Antenna RF input coax, after you have done the Setup/General/Channels/Scan (extended). Scan only finds analog channels. Extended Scan scans for both Analog and Digital channels found active on your Cable/Antenna RF connection.

Note also, the DR570 is not technically and HD receiver. The term High Defintion (HD) is reserved to mean 1080i or p resolution, the highest available. The DR570 is an Extended Definition (ED) 720i or p receiver. It up-converts its ED to fit an a 16:9 HD TV screen. You will hardly notice the difference on your TV, but it is the difference between watching a DVD Movie on a standard DVD player, like this one, as opposed to a full HD player like a Blue Ray.

Change the resolution on the cable box or satellite box, witch ever you have. A set by itself cannot change the resolution, if the cable is giving you 720p, that's what you'll see for that station. All stations do not transmit in HD. The best picture is only as good as they're giving you.

PlayStation 3 XMB Problem


It could be either a problem determining the aspect ratio change between HDMI and your DVI cable or a problem or the settings on your television (You may have the resolution setting too low for HD, does your TV support 720i, 720p, 1080i and 1080p?). If you post back with your model of TV I can help you figure out what's going on.
It's unlikely to be a hardware issue on either connector.
