Re: What a 26" flat pannel TV could be used as a monitor with a DV



I can't explain why, but many TVs say, in their documentation, that PCs are
not supported through HDMI.

But they are. How would a TV know the source is a PC? I suspect it has
something to do with the US' stupid DRM rules.

Thanks Tom for your answer!
I'm going to buy a 32" TV which supports 1360x768 on VGA and has three
pixel
columns on the left and right that are unused.
What did you mean by "I don't believe that is true. Many TVs SAY they
don't
support it, but do." then?

Thanks Tom for your opinion!
Do many TVs support a resolution, equal to its matrix resolution, from
a
computer, although they SAY they don't? Don't they overscan 1360x768
computer
resolution to 1366x768 matrix resolution?

Thanks JW for DVI-I explanation!
Is there a difference in quality on a 26-27" TV between VGA and DVI
interfaces?
The only 26-27" TVs which receive TV's matrix resolution over DVI
are
LG
26LX1R and 26LX2R which have a Headphone output on their back, which
is
very
inconvenient for me.

No only some video cards use DVI-I connectors that have both the

for
Dual DVI connectors as these are the cards most likely to have this
capability.

When video interfaces were first invented for computers to replace
teletypes
or typewriters the character fonts were set at 8 pixels wide by 12
pixels
high so all PC text formats are a multiple of this. This is why
the
firsl
displays which could display 40 80 column punched card images had a
resolution of 640x480.

Samsung informs that HDMI input on its 26" TVs cannot be used for
a
PC,
and
the HDMI input does not accept 1366x768 resolution through it.
I'm going to buy a video card with two outputs. Does every video
card
DVI
output have VGA embedded? Or, Is this adapter a digital to analog
converter?

My LG is the 42" LCD.

As for VGA, your video card should have come with an adapter to
let
a
VGA
monitor connect to the DVI connector. DVI has VGA embedded.

The Samsung has HDMI though. With a DVI to HDMI cable you can
connect
DVI
to the Samsung.

What is a model of your troublesome LG?
Samsungs can not input from a computer DVI output, do they?
I can't find a card with two d-subs, but d-sub and DVI only.
My
computer
monitor has a d-sub only. DVI is left for a TV.

I highly recommend Samsung

I have seen 26LX1D and its manual. 26LX1D is diffenent than
26LX1R
or
26LX2R. "Zoom + / - function is not available in DVI PC
mode."
is
written
in
26LX1R and 26LX2R manuals
(http://gb.lgservice.com/index_b2c.jsp).
There
is
no "Cinema Zoom" in 26LX1R and 26LX2R manuals.
26LX1R and 26LX2R resolution is 1366x768. Why does LG
recommend
1360x768
computer resolution, not 1366x768 then? Does not 26LX2R
stretch
1360
vertical
lines to 1366, use the 6 vertical lines?

Dear JW!
A LG representative said that LG 26LX1R and 26LX1R
(http://gb.lgservice.com/index_b2c.jsp) can be used as a
monitor
from
DVI
computer output without the overscan?
Is this true?

Of course Overscan involve scaling since it "zooms in"
or
upscales
the
video
it receives which is of course why small text fonts in
PC
applications
are
fussy since every 20 line or 20 pixel in a row is
"invented"
by
5%
percent
upscaling which is very common.

Thanks JW for your helpful reply!
The d-sub is used by my computer monitor already. The
DVI
is
left
free.
I
would like to use it to display mpeg 4 movies from my
computer
on
the
TV.
Does overscan includes scaling, which reduces small
text
readability?
A Panasonic specialist said that HDTV 1080i
resolution
is
the
same
as
d-sub
1366*768, and that I can output 1366*768 resolution
from
DVI
compurer
output
to HDTV (1080i capable) TV input, and the scaling
will
not
happen.
Is
this
true?

You can either get a unit which also has a VGA
interface
since
they
do
not
overscan the VGA input since they assume it is from
a
PC.
You
will
not
suffer any degradation in resolution using VGA and
you
may
not
even
notice a
possible slight degradation in video color quality.
I know of not flat panel from the vendors you listed
that
provide a
way
not
to overscan their HDMI/DVI inputs. AFAIK then
Westinghouse
family
of
HD
monitors are the only flat panels that give you
control
of
overscanning.

Hello!
What Panasonic, Toshiba, Samsung, Sharp or any
other
26"
flat
pannel
TV
could be used as a monitor with a DVI output of a
computer
with
the
same resolution as the native resolution of the TV
matrix?
Should
the
computer resolution be the same as the native
resolution
of
the
TV
matrix for a small text being shown clear?
All 26" flat pannel TV manuals with I read
indicate
that
TV's
DVI
or
HDMI input cannot be used with a computer and a
computer
video
resolution could not be the same as the native
resolution
of
the
