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

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.

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.

As long as you ave a true hdmi output on your computer it will work for sound and video. If you are adapting to the hdmi from dvi or anything other than hdmi it will not broadcast sound. It will however give you an hd picture.

No audio on vizio from source


there should not be a special setting that you need. When hooking the analog audio to the HDMI 2 input, it should read automatically. Note: The HDMI Input is for HD Video and will only support 640x480 at 60Hz from a PC. Use the RGB
PC input for a greater selection of PC formats.

Vizio lcd


This model supports the following formats: 1080i, 720p, 720i, 480p, 480i. Most likely it isn't the TV that is not allowing the 1080i resolution but rather your cabling or the inputs that you are using.
Be sure that that you have an HD signal coming into the TV. You may have to upgrade your cable subscription or if you already have the channels sometimes you have to tell your cable box to use 1080. The same goes for DVD players; they often default to only 480 to maximize compatibility.
The other area to check is your cabling. For the best results use HDMI or Component video.

If you have already checked both of these options let me know & I'll try to come up with some other options for you.
