all i see is standard,wide standard,zoom?

check to make sure you are in the correct HDMI input...then make sure you are using one of recommended Resolution settings per the Manual listed on page . 12

You might want to check the 738/838 forums since the HDMI inputs are the same for these sets. Only thing I can recommend is trying various resolution using a PC and then connecting to your HDTV. Also, be sure you have the latest drivers for your graphics card.

I use Nvidia chipsets so I can't help with ATI if the above doesn't work for you.

thanks Shibez, that worked. Funnily my video card does not support 1980 x 1024. Hmmm.

5 OPTIMIZING YOUR DCH RECEIVER FOR HIGH-DEFINITION TV
The DCH6416 outputs HD video through its YPbPr (component), HDMI, or IEEE-1394 connectors. This section describes how to optimize Standard and HD video based on your HDTV and personal preferences.
If you use the IEEE-1394 output, no adjustments to the settings are required.
For a TV with an HDMI connection, be sure the TV is on and connected to the DCH receiver’s HDMI out connector before adjusting the settings. Motorola recommends using HDMI cables less than 20 meters long.
You can use your on-screen menu to configure your HD settings for TV type, HDMI and/or YPbPr video output, and closed captioning.
To optimize the output settings:
1. Be sure your DCH receiver is plugged into a power outlet and connected to your TV.
2. Power off the DCH receiver and then immediately press the MENU key on the front panel. If your TV is on, the on-screen menu lists the settings you can configure:
UseUse your remote control or the cursor keys on the front panel to navigate the on-screen display:
• Press the ▲ and ▼ keys to highlight the setting you wish to change. Press the ► key to select an option for that setting.
• To exit the setting and move to another setting, use the ▲ and ▼ keys.
• To exit the menu and save your settings, press the POWER or MENU key.
The HD settings are described in the table on the following pages.


5 OPTIMIZING YOUR DCH RECEIVER FOR HIGH-DEFINITION TV
12
The HDMI/YPbPr OUTPUT setting is displayed as YPbPr OUTPUT if you are not using the HDMI video connection. The user settings will also be displayed on the front panel display whether your TV is off or on.
If the on-screen display menu does not appear on your HDTV screen, your TV may not support the default video output setting. Use the DCH receiver front panel display to view and change your settings.
1. Use the FORMAT button to cycle video formats
2. Try an alternate video connection
User Settings
Setting
Description
TV Type
Allows you to specify the style of television connected to the DCH receiver. Options include 16:9, 4:3 LETTERBOX, and 4:3 PAN SCAN. By default, the 16:9 option is selected. The options are used as follows:
• 16:9 designates that a widescreen television is connected to the DCH receiver.
• 4:3 LETTERBOX designates that a standard screen television is connected to the DCH receiver and that widescreen programs should be scaled to fit the screen with black bars above and below the picture.
• 4:3 PAN SCAN designates that a standard screen television is connected to the DCH receiver and that widescreen programs should be cropped so that the picture fills the entire screen.
HDMI/YPbPr Output
Allows you to specify the video output format of the DCH receiver for all content (when the 4:3 override setting is Off) or for all 480p, 720p, and 1080i content (when the 4:3 override is used). Options include 1080i, 720p, 480p, and 480i. By default, the 1080i option is selected. The options are used as follows:
• 1080i — The DCH receiver will present programs in the High-Definition 1080i format (1920 x 1080 pixels).
• 720p — The DCH receiver will present programs in the High-Definition 720p format (1280 x 720 pixels).
• 480p — The DCH receiver will present programs in the Enhanced-Definition 480p format (720 x 480 pixels).
• 480i — The DCH receiver will present programs in the Standard-Definition 480i format (720 x 480 pixels).
Some televisions may only support certain video formats. Please consult your television’s user manual for more information on format compatibility.
The DCH receiver can detect when the HDMI connection is in use. If you are not using the HDMI connection on the DCH receiver, the HDMI/YPbPr Output setting will display as YPbPr Output in the User Settings Menu.
4:3 Override
The 4:3 Override setting allows you to specify the video output format of the DCH receiver when it is tuned to a Standard-Definition program or playing back a Standard-Definition program from the DVR. Options include 480i, 480p, Stretch, and Off. By default, the 480i option is selected. The options are used as follows:
• 480i — The DCH receiver will present Standard-Definition programs in the Standard-Definition 480i format (720 x 480 pixels).
• 480p — The DCH receiver will present Standard-Definition programs in the Enhanced-Definition 480p format (720 x 480pixels).
• Stretch — The DCH receiver will automatically stretch all Standard-Definition programs to a widescreen aspect ratio and present the video in the format designated by the HDMI/YPbPr Output setting. Note that the Stretch option is only available when the TV Type setting is 16:9.
• Off — The DCH will create a widescreen version of a Standard Definition program by adding black bars to the left and the right of the picture and present the video in the format designated by the HDMI/YPbPr Output setting.
Some televisions may only support certain video formats. Please consult your television’s user manual for more information on format compatibility.
If the HDMI/YPbPr Output setting is 480i, the 4:3 Override feature is disabled and is no longer selectable in the menu. The 4:3 Override feature is available when the HDMI/YPbPr Output setting is 1080i, 720p, or 480p.

ok SO i assume you have this TV connected by HDMI or Component...Your HD cable box is a bit different than mine...but I think we can start by turning off the 4:3 ovrride if its on...that might fix ur problem..ON my Cable box..my remote actually can stretch or zoom the pic with the # key ...as well as a setting in the menu.

Standard, normal, none...pretty much you want the default. Just cycle through all of them until you see heads not cut off and the video quality that looks good (not stretched).

with the format button on the tv remote....but you cant zoom HD content...you can stretch THEN zoom it...but you lose alot of the picture on both the left and right sides

thanks for all the help,i think im on to something here but need the wife to look at it tommorrow but to me it looks great.i have it 1080i,16.9 ratio,4.3 overide off and im watching it in brilliant because everything else looks to dim.

since 4:3 override is off on certain channels..like espn and abc it will switch to 720p(assuming i read your cable boxes manual correctly)

ALSO its great you found that you like one of the tv settings...which is the setting in ships in...BUT like lucid said its not good to leave it in Brilliant(aka torch mode) it will burn out the light bulb faster.

The TV uses the most Luminance In order from greatest to least - Brilliant-
Bright- Natural and not sure what Game does.

but i found it is possible to get a fantastic picture with this tv even on the dimmest setting (natural) with some minor adjustments in the picture menu.

I was going to calibrate this in brilliant at first but then i realized there is no setting to lower the luminance...
post #104 of 1375
I found the perfect settings for me finally. anyone is welcome to try them.

while the other settings looked good i really didnt like having to switch from the different modes for sports, and bluray, and tv. So I tried to get one mode just right to watch for everything..and also was Bright. I dont have a controlled lit room so i wanted the tv to be bright enough to handle daytime viewing.

and ive come up with this..


o Picture Mode : Bright
o Aspect Ratio/Format : Standard
* Picture Settings
o Contrast : 72
o Brightness : 46
o Color :38
o Tint : 9
o Sharpness : 0
o Color Temperature : high
o Video Noise : Off
o film mode : off

These work very well for bluray as well..

these are all with HDMI(high speed) cable hookup

I know 72 for contrast seems nuts but try watching a movie with a lot of snow in(like skiing)...or scene where the sun is shining on a persons white shirt..you cant make out any detail in white scenes..just looks like a white blotch. 72 contrast helps this alot.(on bright mode)

I just purchased a 73638 and have to pick it up at best buy... 4 hours away. Reason being is the 1199 sale they were having was only showing available at a store 4 hours away with no home delivery in my area. Sucks. I have a couple questions?
1. Does this tv come in a box like every other tv?
2. It is suppose to be in the 30's all day. Will this harm the tv if it is in the back of a truck? I plan on tarping it.
3. Does anyone have the exact dimensions of the box?

By the way the funny thing is the day the deal for 1199 stops it is suddenly available for home delivery and store pick up in my area. What a crock of ****
post #107 of 1375
well today is another day and im closer than yesterday,on my hd channels some channels look great like abc,fox,but then espn i have to adjust the picture setting to make it better and then the others start looking bad and like when im watching espn and they show a highlight of a game the highlight looks bad but espn part looks great.we just watch storm chasers and it look grannie as crap,i dont know what to do.
post #108 of 1375
Hey guys, is anyone using this with a PC through HDMI? I'm asking because most of the tv, save for the outer edges of the screen, is blurry. I've tried correcting it through adding sharpness, etc, but none of it seems to work. I don't know what might be the problem. I've tried setting the TV further away but it doesn't really help, and I've tried 2 different HDMI cables and it still persists.


EDIT: Wow, I just found the weirdest solution. I ended up walking to my tv, and just gently pushing in the screen and it instantly became clear. Does anyone else have this problem? Maybe they didn't tighten my screen enough at the factory that it's becoming distorted like that?

My status on the website has been showing "approved" for a few days now, and I got the same email this afternoon... which, allowing for the holiday, is effectively about a week after I mailed the form.

sometimes when they show highlights of games theyre not in HD but they show them anyways...like when theyre on a live sports center

also how about watching BLURAY...you do know thats the only way to watch something in spectacular 1080p right?(well unless you have hddvd)
post #111 of 1375
Does anyone know If these sets can do 1080p24? i know there is a setting in the menu but that says its only for 1080i and 720p content... what about bluray?

ESPN highlight clips are re-compressed video clips and look like crap in general. But they're just "clips". Save your opinion for the "actual" game itself. But you can make the crappy channels/shows better by using an external video processor but don't expect it to make it look like blu-ray, just better than what you're seeing now. The 738/838 have a better video processor so those channels will look better on those sets but it still will be flawed.

If David Letterman, Leno, and the Nightly News look great then you got a good HDTV. If the lower quality channels/shows look like crap then you got a crappy video processor, which the C10/638 are known to have. I'd recommend get a Cable card and using a HTPC to output all your content. It can also become your DVR and without all the cable box and DVR fees that cable companies rip people off with. That way all your content will output the PC at 1080p where your PC does all the scaling, aspect ratio, and other video adjustments at a much higher quality than your HDTV.

You can input 1080p 24fps BUT it will not do 5:5 or 3:3 pulldown. The main reason for inputting a 24fps signal is so you can do one of those pulldowns to eliminate judder. These sets do 3:2 pulldown which eliminates most judder but not all of it. 3:2 pulldown is what most early HDTV and analog TVs used (mainly done in the DVD player before giving the signal to the TV) so you've probably always watched movies that way.

But for the price of these sets you CAN'T expect 5:5 or 3:3 pulldown. The higher end sets (738/838) should have this feature. But it's a limitations because of the DLP chip that Mitsubishi uses. TI, the maker of the DLP chips, is said to offer a full frame DLP chip which will allow future DLP sets to do 5:5 pulldown. It's not known if Mitsubishi will use that newer DLP chip in their full product line. I would assume that they won't unless TI wants to eliminate having to produce the older chips.

Bottom line, you're getting the most you can expect out of your HDTV given the price. Input 1080p sources and you got a HUGE bargain compared to LCD/Plasma.

Note: I would recommend leaving your source player/rec. do the 3:2 pulldown because the video processor in these sets probably isn't as good as what the external boxes can do. Not all devices will output 24 fps output.

Ok thank you for explaining it to me ..but something I dont still quite understand ....Does this tv automatically recognize 24frames for "1080p" Or Do i have to enable it with that "film mode" also Film mode says its only for
1080i and 720p.

And my samsung Bluray has an option to output 24frames.

nevermind I read your first sentence over again LOL

I'm having some issues connecting my htpc/laptop to my tv

relevant info:

Mitsubishi 60" WD-60638 DLP television

HTPC running windows 7 x64
using integrated graphic (nvidia 8200???)


Everything was working perfect on my Samsung 32inch but will not play nicely with the DLP. The television will display "No Signal" Whenever i turn it to the appropriate input. I have tried different cables and different computers (a laptop i have that has hdmi out does the exact same thing)

I can get it to "work" two ways:

1) I turn on the tv, put the input to the appropriate hdmi port, then start the computer. I can navigate through the desktop and watch videos BUT if i change the input then try and change it back "No Signal" is displayed :/

2) I turn everything on (dlp tv, computer, and 32 inch samsung), plug the hdmi port into the samsung, take it out, then plug it into the dlp. It will recognize the signal that way. Once again, when the input is changed, "No Signal" will be displayed.

I really want to keep this TV but don't want to jump through hoops every time I want to watch something. If anyone has experience with these particular television sets and htpc, you're help would be greatly appreciated.

Have you tried disabling the screensaver or power modes on your PC. Sounds like your PC is going into a sleep mode (no signal) after some time and then when you're ready to go back to your PC there's no signal from it to detect, because it's in sleep mode (display wise).
post #117 of 1375
Thank you for your reply.

Yes, I the screensaver is "disabled" (It's set to 999 so that it doesn't have time to kick on)

Also, sleep is completely disabled.

My typical turn on procedure is:

-turn on tv
-turn on computer
-wait 40 seconds until desktop appears (note: it doesn't show bios screen)
-mess around on the desktop for a little bit
-change input from hdmi-2 (which is also labeled pc) to hdmi
-wait 5 seconds
-change it back to hdmi-2 ( "No Signal" is displayed)

As soon as I change the input, I can't get back to my pc input. This is very frustrating. I was posting here to see if any one else is having problems connecting a pc to the tv.

Hmmm...it could be your PC then, or the chipset. I'm still waiting on my C10 to be shipped from Dell - still in a "In Production" state. But I have a HTPC that is using a Nvidia 9300 based chipset. My HTPC works fine on my Sony WEGA 50" HDTV set that I bought 8 years ago. But that's using a HDMI to DVI adapter (DVI input on the HDTV).

Once I get my set I'll report my HTPC experiences along with my calibration settings (settings both on HDTV and HTPC) so others can max. out these sets in that ideal setup. Or at least give them a good baseline to work with.

But if my C10 has problems like you described it's going back to Dell even if I have to pay the return shipping costs. Since I use my HTPC for ALL my content it's a must support device.

I thought it was my pc also, but I have a laptop w/ hdmi out that does the same thing also. The only thing they have in common is that they are both Nvidia.

I am using this tv soley for the purpose of my HTPC and if I can't get it working I will have to send it back

What's the chipset version is your laptop using. The motherboard I'm using has built in graphics which is designed to be used as a HTPC - even powers on from a sleep state to record TV, so you don't have to leave it on 24/7.
