Help in connecting my laptop to HDTV via AVR

[dotMac]

Can you please tell me how to enable hd audio pass thru in ati radeon hd5850?

it is already running on latest drivers

i use onkyo 3300 which can decode hd audio when i play same BD with bdp-s370 it displays dts master audio , when played with htpc(liteon bluray drive,hd 5850, TMT3 , win 7 64 bit, hdmi) it shows only dts

in the player(TMT3) audio settings i selected output mode : hdmi and mixing mode :using original primary

in catalyst control centre (control panel for GC) i dont see any audio option

Playback devices / Sound i see ATI Hdmi output is the default audio device enabled and its properties i can see dts hd and dolby tru hd under supported formats)

You would have to set in the software player settings to let the HD audio to be pass through so that your AVR can process sound.
In PowerDVD 10 :

The audio setting in PowerDVD 10:

Click on the "Configure PDVD settings" button to open the settings window.
Select the Audio tab.
The Speaker environment should be set to HDMI.
The output mode should be set to Non-decoded high-definition audio.

Now your AVR must display DTS MA when playing Bluray Disk.

In case you use a different software to play BluRay, the settings would differ.

No I am using windows 7, it has it own rules ......... I get the following window when I go to resolution window in 7 ....

But I finally figured how to get it done, strange may it seems but, this is how win 7 perceives. You DO NOT get the option for 1080p with your laptop screen/lid open, I was doing all sort of RnD, when I had to go to the lu .... the moment I closed my laptops lid to go, the display on my LCD flickered and I got a screen with my icons out if screen border ( much like aneelr ), I immidiately checked the resolution at it was 1920x1080 ... .... ...... then I flipped open my laptop lid again and vola! the screen flickers again and the res becomes 1360x786 on both the displays....... strange isnt it ... . Close the lid and LCD has full 1080p ....lol...... now the misplaced icons, all I had to do was to choose "JUST SCAN" on my LCD and everything was fit and perfect ........ man I learnt a new thing in this experiment .......
If any one can figure out to get full 1080p on both displays on Win 7 Notebook with the lid open I am all ears .....

You cannot get 1080p in both displays as your laptop screen is not capable of displaying at that resolution. Its maximum seems to be 1360x786.
So you can either have,
1. 1360x786 for both display (as you see it now)
or
2. 1360x786 on Laptop and 1080p on HDTV.

In case you want the second setting (i.e. 1080p on TV), you need to set the 4th checkbox named "Multiple Displays" to "Extend these displays".
Once you apply above settings,
you will be able to set the resolution of laptop and HDTV independently by selecting Display "1" and "2". Display "2" is disabled unless set to "Extend these displays".

You are currently using "Duplicate display" mode. In this both screens must have the same resolution. So Win7 chooses the least resolution among the two. In your case its laptop's resolution which is less and thus imposes that resolution on TV. When you close the lid, laptop resolution is no longer the constraint and thus Win7 switches to 1080p which is native resolution of TV.
If I am not wrong, opening back the laptop lid should cause the TV to switch back to laptop resolution as it is again the limiting(least) resolution of the two.

More about Extend mode :
In this mode, each screen will have its own native resolution and it acts as if two displays are stitched together on their sides. So when you move a window sideways, it will move from one screen to other as if the 2nd screen was part of 1st.
In this mode you can set one of the display as "Main Display". Here is how.

I generally use the extended mode as HDTV runs in full 1080p. When watching movie or browsing, I drag the browser or VLC player to the TV screen and then go full screen. But I use a Mac. But same thing must happen on windows.
Also in extended mode, you may be able to set the way the two displays to be stitched. i.e. As you observed, moving the window/cursor to the right made it move to TV. You can make that transition to happen when you move either on top, bottom, left or right. If you set this based on your physical positioning of two displays, the transition becomes intuitive.

I am using TMT3 software player, already set audio hdmi and output mix mode as use original primary but still cant see my avr display dts ma

from your post looks like i have to make powerdvd work, for some reason powerdvd is not working in my system(win 7 64), i tried different versions, it just starts and closes itself

Just checked spec page of TMT3 out of curiosity here : TotalMedia Theatre 3 Platinum .

Quote from above page :

Support HDMI 1.3 Pass-through Technology for Lossless 7.1 Channel Audio Output**
With DTS-HD Premium Audio Output via HDMI 1.3, TotalMedia Theatre 3 provides full high-definition audio digital output, enabling lossless audio such as DTS-HD Master Audio, Dolby TrueHD, and Dolby Digital Plus, to be transferred to the AV receivers for high-fidelity sounds - up to 192 kHz sampling frequency and 24-bit audio resolution, offering exceptional audio experience.

**ASUS Xonar HDAV series audio card, ATI 5xxx video card or an Intel Clarkdale motherboard required.

So I guess with right settings and latest TMT3 Platinum, you must be able to get HD audio.

For PowerDVD make sure that it is latest build in series 10.

I think you missed reading my post answered to anleer,.....lol I knw may lappy can not have 1080p (I feel dumb even mentioning this), I also addressed about stretching my desktop, also wrote about the mouse movement, you totally missed that post I guess. I also mentioned it would seem to be a pretty absurd way of playing a file on the LCD by extending the desktop. Anyway I am ok with keeping the lid closed, that too, if for some reason I would want to watch a movie via my laptop ( which would be extremly rare, only on an occasion IF my POHD isnt able to play some file, which hasnt happened yet), else it was just an experiment and I admit, keeping the lid down to get the full HD on the LCD was something new I learnt ......

Oops. Sorry about that. I too misunderstood your quote,

If any one can figure out to get full 1080p on both displays on Win 7 Notebook with the lid open I am all ears

I read you below post now

What I meant was 1080p on LCD with lid open, I know my notebook cannot display 1080p ... , also extending desktop just gives me an extra desktop apart from the one I have on my laptop, if I move my mouse all the way to right it crosses the border and I then can see the pointer on my LCD. There I cannt do much as its just a plain desktop with nothing else. I might try shifting the "My computer" to the other desktop and try opening up the file, but this seems to be an absurd way of playing a file.

What I meant was if there is a way to keep the lid open, and have 1080p on my LCD.

Only way I could see this happen in you current laptop is, if you change the mode to "Extend these displays".

But I would agree with digitalv on ......lot of GPU power required to play HD content on both the displays with different resolution at the same time. Probably that is why by closing the lid we disable one display to have full HD on LCD

@all,
Someone correct me if I am wrong. IMHO, it is not the GPU power that is causing the LCD TV to go for the lower resolution. Instead it is because of the "Duplicate display" mode(or Mirror mode in Mac) used.
In this mode, the OS always uses the lowest native resolution out of the available display. So in case you have 3 monitors connected, the resolution of all the three monitors would be same and that would be the minimum native resolution supported by one of the three monitor. Eg: If one support 720p max, other 1080p and third just 1024x768, all three monitors will be running on 1024x768.

On the other hand, if the mode is changes to "Extend these displays", the three monitors will be run on its own native resolution and User will be allowed to change them individually.

When the laptop lid is closed, what is essentially happening is, one of the display is disconnected and hence TV goes to 1080p which is its recommended native resolution.

Note : The above query is just for my information and to correct myself if I got it wrong.

Logically explanation seems correct, but have you tried to figure out why OS uses the lowest native resolution of the two/three displayes (with different res). Probably because of the same reason, that it would be taxing on the GPU to provide different res on different displays, or may be it isnt even possible to have different resolution on multiple monitors connected.
Either we have lowest res on all displays OR one has to be closed (only in case of low horsepower GPU).

That is not the case. Even On board GPU has more than enough power to drive 2 displays at HD resolutions.

 

[sam9s]

First......We are not talking about "one the same resolution", but different resolution for all the displays connected ...... Second its not the desktop on board GPU we are talking about, but the integrated GPU present in the laptops.

 

[NetFreak]

My laptop has intel integrated GPU, it can comfortably drive my plasma TV at HD + its own screen at native resolution.

 

[sam9s]

Okie ....^^ If it has windows 7 can you let us know how to do this by keeping the lid open ...

I am almost sure that NetFreak is using extended mode rather than mirror mode.
Again I believe it is not due to GPU's incapability of handling multiple monitors in full native resolution as it indeed does so when you set extended mode.

The reason I see for this behavior is that, in mirror mode, graphics driver or OS creates one frame buffer and feeds it to two displays. So their resolution has to match.

In extended mode, OS creates one large frame buffer, slices it to two parts and feed each monitor one piece.

Have you tried 3rd party apps like Ultramon?
It might let you do that. As I am Mac user, I cannot try it and hence no guarantee that it would work

Otherwise in Mirror mode, the drivers retain same resolution.
3rd party solution may work by intercepting the frame buffer created for lower resolution and then scale it for TV and pass the scaled buffer. Just a guess.

Sam, why it cant be the other way? If a full HD resolution is forced to a screen with lesser resolution, it will not display anything. Thats the reason the lowest resolution is taken, as a safe bet, i dont see any other reason. Nowadays integrated GC can easily run displays with multiple resolutions.

 

[sam9s]

^^ I am not denying the fact that there could be another reason, ......but I guess you have not read what am I trying to figure out ........why I have to keep the lid closed of my laptop to get full HD on my LCD, why can I not keep the lid open. Coz the moment I open the lid the OS reverts to 1366x786 res on both displays (on lap top it would as its the native res, but why on LCD as well???) ....... I agree less GPU power is not one of the most convincing explanations here, but neither are the othesr discussed
