I am also trying to figure out how to display 4:3 content on my
16:9 screen w/out zooming.
Here's the result of my research into this topic:
At first glance, it would appear that the Center 4-3 Computer
Material on 16-9 Screen (Perfect Timing)
found on theDilard Download page
is the Dilard-equivalent of the Non-Zoomed 4:3 Display on a 16:9
previously offered by Mark Foster and described inthis thread
My video material is the 4:3 test pattern from Video Essentials
(Video Test Patterns, Chapter 17). The DVD is playing from my HTPC
via PowerDVD 3.0 configured to use the full-screen (ie, lock aspect ratio
is not checked). The HTPC is connected to the G11 computer 1 input.
The HTPC is running Powerstrip 3.0 and in the case of this test is set
for the DILA 1360x1024 perfect timings.
With that setup and the G11 on the SXGA3 source, the image is filling
the entire G11 panel and of course shoots above and below my 16:9 screen.
However, the image geometry is correct. The circles in the test pattern
are round and the entire source image fits the full video image.
It just does not fit my 16:9 screen.
However, when switching to the modified XGA1 source, the image fits
inside the screen but the bottom two circles are cropped to the point
that only the top portion of the circles (now ovals) show. The image
is also horizontally squeezed.
I traded some short emails with Mark Hunter in which he stated that
this mod was created for some 4:3 DirectX games he plays and is not
appropriate for what we are trying to do. He suggested that I modify
the default SXGA2 setting and aim for a centered 1024x768 image with
~82% horizontal scaling.
I won't be able to play with Dilard and my projector until late
next week, but I wanted to post this information as it seems that
several other people are trying to figure out the answer to this
