I don't know where to find the cmdline; I have never used xrandr; and
there is no xorg.conf anywhere in my box.
cat /proc/cmdline returns the following:

This is my parentboard:
http://www.gigabyte.com/products/product-page.aspx?pid=4600#ov
The chipset is the Intel Z87 which is the same as the H87, except the
Z87 is designed for overclocking whhich I do not use.

Note that there are two audio controllers and two ethernet
controllers. I am not sure which auto controller is used --or whether
it matters -- but I have to use the Atheros ethernet controller
because the Intel one does not work.
I have a box with Debian Wheezy and TDE installed
in it.
So do I. :-)
This is its motherboard:
http://us.msi.com/product/motherboard/B85-G41-PC-Mate.html
What's yours? At least, tell which chipset and video you have via
lspci output. The GPU has
three connectors, one DVI and two HDMI.
Mine has one each of VGA, DVI and HDMI. I have two
monitors connected to it.
Again do I. :-)
The diagonal measurement of one is 49 cm. It has
a 1600x900
resolution and is connected to the box by a DVI cable.
Diagonal of my 1680x1050 connected via VGA cable is 56cm.
> The other is a TV/monitor with a diagonal measurement of 124 cm
> (49 inches). It is connected to the box by HDMI. Diagonal of my 1920x1080 connected by DVI to PC and
HDMI to TV is
80cm.
It is a 1.4a HDMI cable 10 m long.
The box recognizes its existence, but the display
on it has the
same resolution as the smaller monitor.
Can't say for sure why, but based on my experience, it should be a
surmountable problem. Possibly HDCP is affecting behavior, or the
HDMI cable. Have you tried any other cables? Cheaper HDMI cables
are often a cause of otherwise inexplicable trouble. It
consequently uses only about 40-45% of the screen area, nor is
it centred on the screen.
What's likely to be happening here is that the TV does not support
the lower 1600x900 mode that Xorg automatically uses without being
told otherwise for the larger resolution screen, so both falls back
to a lower mode, and displays that mode without stretching,
confining to the pixels on the 1920x1080 screen matching the actual
mode used. If there is a video mode dictated on the kernel's
cmdline (from bootloader), Xorg could be using it, as the Intel
driver will do so unless told by xrandr or xorg.conf* to do
otherwise. It starts more or less from the upper left corner
and leaves an L
shaped unused black space on the bottom and right sides. The
left side does not correspond to the left side of the screen; a
strip on the left side of the display is seen on the smaller
monitor but not on the large one.
IME, black/blank space is always at either bottom or right, but
only in a screenshot, not on the screen output.
Sounds like neither display is being run in native mode. What is
output from 'cat /proc/cmdline'? The whole of /var/log/Xorg.0.log
may provide additional useful info. > Is it possible to create a display resolution

The rest of your post is so far beyond my experience and will require
more study on my part of the URLs on your website. I do not have time
to do that study tonight or for obvious reasons in the next few days.
I may have questions to ask later.
In any event, thank you for all the information herein. I have
learned a lot already, but obviously I have more to learn. I feel
that it is only a matter of time before I solve the problem I
described in my original post.

Using TDE controls I've never tried. I always
trust Xorg
configuration to get screens the way I want them. Here are two such
ways:
Over/Under:
http://fm.no-ip.com/SS/KDE/tdeDesktop-1920x2130x120viaXrandr-iHaswell.jpg
Side by side:
http://fm.no-ip.com/SS/KDE/tdeDesktop-3600x1080x120viaXorgdotconf-iHaswell.…
In the over/under you can see the xrandr command responsible in
the Konsole windows (and from whence it came, a personal creation).
For the side by side I used this xorg.conf instead of xrandr:
http://fm.no-ip.com/Share/Linux/xorg.conf-intel-vga1680x1050left-digi1920x1…
Of course the disparity between my screen sizes and yours are
smaller, but they do have different native resolutions, and
principles in controlling them are the same.
Note that in both my configurations I have forced logical DPI to a
value that suits my needs. Via xrandr there are two ways to do
this, --dpi and --fbmm. In xorg.conf, DisplaySize controls it. You
can pick one that best suits your environment and display size
disparity. If you don't, DPI will be forced to 96 on the lower
resolution screen, and fall where happenstance puts it on the
larger. Here's a file with examples, saving the trouble of
calculating sizes to achieve many DPI possibilities:

This is the web URL shown in the Firefox and SeaMonkey windows:
http://fm.no-ip.com/Auth/dpi-screen-window.html
This is the script responsible for the output shown in the Konsole
windows: http://fm.no-ip.com/Share/Linux/xfetch.sh
Hope this helps!
