Re: still no way to do custom aspect ratios?

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Your comment is... baffling. I'm not sending Media Center 1024x768
video, IT is sending 1024x768 video to my TV. The video that Media
Center is playing starts out in various resolutions like 1280x720,
1920x1080, 720x480, etc. And no, telling Media Center that my TV is
4:3 wouldn't help at all (believe me, I tried it). It is asking for
the PHYSICAL aspect ratio of the television. It is not asking about
the native pixel aspect ratio. MC actually doesn't pay ANY attention
to whether you tell it your TV is 4:3 or 16:9 if it looks at your
desktop resolution and thinks the resolution in the matching aspect
ratio. For example, if I go through the wizard, choose 16:9 and tell
it "No" at the box where it asks if I want to change resolution, it
will actually act the same as if I go through the wizard and choose
4:3. The result is a 4:3 image stretched horizontally over the length
of my widescreen TV.

are 33% wider then they are tall.
I do not know if telling MC you had a 4:3 aspect ratio display would have
made it any simpler to accomplish the correct end result
On my Vista system I use both MC and the Hauppauge WinTV program for
watching TV. I only use MC when I want to have time shift capability
available or to record programs. I use the direct Video capability of WinTV
to avoid the extra resources required and poorer video quality provided by
having the video encoded and then decoded again.

Oh, and I should mention that this doesn't help me at all on the PAL
video files. I still need to be able to tweak the aspect ratio at
will to trick it into intentionally squishing the video horizontally
so that it will look right on my screen. I'm either going to just
deal with it, play those files outside of MC, or figure out how to
edit the file information so that it thinks it should play them in a
different aspect ratio (if possible).

In this regard, other video players custom aspect ratio settings are
superior. It's so sad that even Windows Media Player has this
ability, and MC doesn't. Then again, you can't tie it to a hotkey in
WMP like you can in other players. This certainly makes it less user
friendly.

Looking back, I don't actually think I did use resolution and aspect
ratio interchangably. At one point I referred to a "4:3 resolution",
but that was just meaning a resolution where the physical height and
width were in a 4:3 ratio.

In any case, I'm glad that we're getting through the confusion. In
any case, good news! I've figured out how to fix it, and it's not
pretty.

Set your desktop resolution to 1024x768 and run Media Center.

Go to Configure Your TV or Monitor.

Go through the steps and choose 16:9 which it asks.

On the next screen, it will complain that you are running 1024x768 and
yet chose 16:9 and this is probably not right. It will ask if you
want to change your resolution. Say Yes.

On the next screen, it lists various resolutions. Choose 1024x768.
That's not a typo. Yes, you are already at 1024x768, but trust me.

When it asks if you want to preview, say Yes. If you don't do this,
it won't work. At least it didn't for me.

The screen should now change aspect ratios, but not resolutions. In
other words, text will stop looking stretched out. Say Yes to the
question of whether you want to keep this resolution.

That's it, you should be all set. Your resolution in Media Center
will stay 1024x768, but Media Center will know it needs to compensate
for the TV being 16:9.

The problem I kept having was that doing it this way is completely
confusing. It's not a way almost anyone would guess. I actually got
to this point by choosing 1360x768, then poking around at the registry
and editing it by hand. Armed with the knowledge of what this was
doing, I went back and figured out how you're "supposed" to do it.

Now, the only question I have left in my mind is if I should fiddle
with the resulting registry settings. It changed some settings under
HKLM\Software\Microsoft\Windows\CurrentVersion\Media Center\Settings
\Display Device

PhysicalWidth=1024
PhysicalHeight=768

LogicalWidth=1365
LogicalHeight=768

I can change LogicalWidth to 16 and LogicalHeight to 9 and the results
are pretty much identical to the above settings. I wonder if there's
any benefit at all to having one over the other.

Anyway, thanks for your help. I'm going to go post this response to
all the orphaned messages on this group asking the same question.

I believe I now understand what is and is not working for you. I think I
was
a little confused by your use of Aspect Ratio and Resolution
interchangeably.
Let us know if the following is correct and makes sense.

1024x768 is one of the standard resolutions used on square pixel 4:3
aspect
ratio displays to get full screen correctly proportioned video as are
many
of the other resolutions you mentioned.
1280x720(720p) along with 1920x1080( i or p) are resolutions used to get
full screen correctly proportioned video on square pixel 16x9 aspect
ratio
displays.
Your 1024x768 plasma TV has a 4:3 logical(real) aspect ratio and a 16x9
physical(appearance) aspect ratio.
When setting up your TV in Media Center it assumes square pixels and
wants
to know your aspect ratio in order that it can:

Give you a choice when sending a 16:9 HD program to a 4:3 aspect ratio
display of letterbox or zoom mode.
-or-
Give you a choice when sending a 4:3 SD program to a 16:9 aspect ratio
display of widescreen stretch mode or normal 4:3 plus side bars modes.

Many other programs. like the ones mentioned, depend on the user to pick
the
resolution that is appropriate for his display and for his source
material
and do not offer the options that MC does. Which by the way are similar
to
what digital STBs in conjunction with HDTVs offer for display modes.

If you want to send 1024x768 resolution to your TV in MC you need to
tell MC
that you have a 4:3 aspect ratio display and not a 16:9 display since it
is
asking for your logical and not your physical aspect ratio.

I'm sorry folks, but this is a little frustrating. Forgive me for
sounding snippy at all. Did you ever get my point about other media
players, including Windows Media Player, having the ability to
configure what aspect ratio your display is? It does not have
anything to do with my video card. It has to do with the DISPLAY.
The point is that the media playing software will play various
sources:
1280x720 HDTV OTA broadcast
720x480 NTSC DVDs
720x576 PAL DVDs
Video files in various resolutions such as 352x240, 720x576, 352x224,
480x360, and 1920x1080, among others.

Now, no matter what output resolution you have Windows set to output,
these video files will have to be rescaled _by the media player_ in
order to fill the screen. Yeah, sure, if you have your desktop
resolution set to 1280x720, the HDTV broadcasts won't be resized by
the media player. But all the other sources will be.

Now, that's rescale #1.

If you have a TV that has a native resolution of 1024x768, widescreen
or otherwise, and you feed it a signal that isn't 1024x768, it will
have to rescale it to 1024x768. This means dropping some pixels when
downconverting from higher resolutions and adding pixels when
upconverting from lower resolutions.

That's rescale #2.

I'm trying to cut this down to a single rescale, as every time you
rescale, you muddy up the picture. This is especially true when you
upconvert something and then downconvert it.

That is why I'm trying to be able to set Windows to a desktop
resolution of 1024x768. I can do that just fine. I can then run any
number of media players like Windows Media Player, SMPlayer, and
ZoomPlayer and tell them that even though the desktop is 1024x768,
when they convert them to 1024x768, they should take into acount the
aspect ratio of 16:9. This way, the only do ONE rescale operation to
go from, for example, 720x480 directly to 1024x768 widescreen. Then
my tv gets the signal and doesn't have to rescale it at all, thus
avoiding a quality loss.

I'd like to stress that I can do EVERYTHING in the above paragraph in
other media players. I just can't do it in Windows Media Center in
any way that I can figure out. My point in posting is to see if
there's some kind of hack or hidden preference, or to try to figure
out where I can get this point across to someone who actually works on
Media Center so they can consider fixing it in the future. I love the
software and want to use it, but until this is a possibility, that's
not going to work.

Thanks again for taking the time to try to help.

I don't think you fully understood my posts. The problem is not in
being able to pick resolutions. The problem is in that Media
Center
does not seem to know how to handle rectangular pixel displays.
