HTPC can you have 576i/480i and 1080p ? (1 Viewer)

[Meridius]

Hi all i was woundering if you could output 1080p for blu-ray so that teh pc and tv are not upscaling or touching the picture in anyway and also be able to send divx,dvds out in 576i/480i as i was thinking of using an external scaler for that.

what i am after is for the pc not to scale anything at all but when i place a blu-ray into my computer it will send out 1080p.

can tis be done i am going to use win7 and media portal as media portal has an option for selecting the right refresh rates for your videos to

so can you have the pc do

1 dvds/divx 1080p to tv and mkv/blu-ray 1080p to tv
2 dvd/divx 576i/480i to tv and mkv/blu-ray 1080p to tv


can you do this meaning you have the option of the px doing the upscaling or the tv or external scaler.

ok so say i wanted to send these out from my pc

if i wanted to setup my pc to upscale everything

1 1080p blu-ray native as its already 1080p
2 720p mkv pc upscales it to 1080p
3 dvd 576i/480i pc upscales it to 1080p

so basicly the pc upscales everything to 1080p

but if i wanted to use an external scaler could i set the pc to

1 1080p blu-ray native to tv or scaler
2 720p mkv native to tv or scaler
3 dvd 576i/480i native to tv or scaler

so that the blu-ray is untouched as its already 1080p but then the external scaler will upscale the 720p/576i/480i to 1080p then sends it to my tv.

can a pc not be set to output native res of the source does media portal do this automaticly if so how do you turn it on.

the only 2 options i want is 1 let the pc upscale everything or 2 let the pc p[lay everything native to my tv or scaler as i do have a high end external scaler.

i am looking to get a motherboard with a on board nvidia 9400 gfx chip

can you do this with media portal

thanks

Well I know you can have the video stay untouched but not sure how the pc sends the signal out when doing that.

In conifg under video you can set defult zoom mode to (Original) or to test just change the zoom mode while playing, and it will play the video at its actual resolution, but like I said not sure how the pc sends the signal out, it probably sends the signal 1080p still but just sends the black border for the video also, but I am just guessing.

Hopefully someone can chime in that knows a little more about the video player.

Good luck I am gonna watch this thread since I was looking at getting a standalone scaler also.

Sorry, but currently there is no way to change the video output resolution based on the media file properties. It might be possible with using ReClock to detect video resolution and then use ReClock's scripting ability to use some external display mode changer (PowerStrip / dc.exe) to change to the wanted resolution.

...most likely such change will break MediaPortal completely as it is no designed to handle display mode changes on the fly (only thing it can cope is refresh rate changes). But it might be worth to try.

After all, today's GPUs have pretty high quality scaling algorithms so the difference between external scaler and GPU based scaling are going to be pretty minimal (most likely cheaper scalers are going to lose).

so what your saying is that a pc can produce and upscaler the same imageor better quality than a Reon HVQ upscaler ? as these are one of the best scalers at there price range.

No, I'm not saying that as I have no such HW to test with

there must be a way

MediaPortal's code doesn't support such, so you need to use some 3rd patry application to change the resolution during playback statup. And there is no quarantee that MediaPortal will survive from such as it is not designed to support such.

So, as the first step I would test following:

1) Start MediaPortal
2) Start video playback
3) Use display adapters control panel to change he resolution to something else than the current one
4) Stop video playback
5) change resolution again to something else

if MediaPortal survives from that then there is hope and you can use the proposal that I wrote in "2009-08-21 08:52" post.
