Problem using an LCD TV with a DVI input as a computer monitor

Hello,

I am having a problem using my new TV (a Toshiba 27WL46B) as a monitor for
my computer over a DVI-D connection.
My graphics card is a GeForce FX 5200 with twin outputs, one VGA & one DVI.
The TV claims to be 1280x720 native resolution but the only resolutions I am
offered in the Display Settings are 640x480, 800x600 & 1024x768.
I have downloaded and installed the latest Nvidia driver (66.93) in the hope
that it would offer 16:9 resolutions or permit me to add a 1280x720 custom
resolution. Whilst the Add Custom resolution dialogue is now available it
won't permit me to add 1280x720 (or any other 16:9 resolution for that
matter).
Is this problem at the TV end or the computer end? In other words is it the
TV that tells the driver what resolutions it can support?
Does the monitor type need to be identified in some way before it will offer
me the resolution required?
I can use a VGA connection but the screen is so fuzzy (at any resolution) as
to be unusable.
I have bought this TV specifically to be both a TV & monitor.
If I cannot get it to work for the purpose intended it will have to be
returned.

regards,

Neil Manning

it's the pc - it's not offering the resolution you want.
simple answer is get hold of an application called powerstrip - that should
allow you to create the resolution you desire.

the screen probably looks fuzzy because you're not feeding it the correct
resolution.

am using VGA with the screen cloned to the s-video TV-out to the
television.

Just realised, this TV is 1280x768 not 720, give that a try.

Funny enough I installed nvidia 66.93 yesterday on an old computer I was
selling to a neighbour.
I had it connected to a 4:3 19" CRT, but because my neighbour was going to
connect it to a widescreen LG LCD TV/Monitor, I checked out it would offer a
wide range of resolution including 16:9.
Even though the computer uses an older MX400, it offered me just about every
permutation going with a wide range of 16:9 settings including 1280x720 ,
BUT this was connected via VGA which he will use too.

The monitor/TV does tell the Graphics card what resolutions it supports.
Does the correct monitor show up in your display settings?
Might you need to update the monitor driver, rather than the graphics
driver?

Try a Windows Update and see if you get an updated monitor driver.

Read the post in the link below, Toshiba have admitted that the DVI
connector is only designed to run at 1024 x768.
With an ATI card I have a worse problem and cannot use DVI at all as the
screen does not issue an EDID (Extended Display Identification Data)and
so is not recognised as plug and play by the ATI drivers.
Your alternatives are use VGA, put up with the wrong resolution or send
it back.
