Monitor doesn't display in anything but safe mode!

Hi,

I'm trying to use my TV as a monitor, using a DVI-->VGA connection. I can
see it load up, but once it begins to actually load Vista the screen reports
"no signal detected". If I boot in safe mode, however, it does display. Can
anyone help me out???
 
TVs support a maximum resolution of 800x600. Typical is 640x480. Your best
bet is to use the TV as a secondary display. Even if your TV was 10 meters
wide and high, the maximum res is 800x600 with the analog video signal. If
it's a high definition plasma panel. I've seen them with VGS inputs and
support up to 1024x768. Try making the desktop resolution 1024x768 or even
800x600 while your monitor is connected. Reboot the computer with the TV
connected and it should be fine then.
 
The information from Andrew applies to a TVs S-Video or composite and not to
other interfaces.
While the PC is loading up it is sending the video at 480i or 480p. Once
Windows is running it sends at whatever resolution you have selected. Check
to be sure the resolution you have selected is one which your TV will accept
with its VGA connection. If it is digital technology TV the best resolution
to use is the TVs native resolution. However, it the native resolution is
1366x768 you normally have to send 1360x768.
 
Thanks for the responses. At the closest native resolution the monitor now
displays "out of range" message...at lower resolutions it does display for
around 10 seconds before returning to "no signal detected"...any further
ideas as to what is going on???
 
What is the make and model of your TV and of your Graphics card? And what
release of the drivers for your graphics card are you using?
 
The TV is a DMTech LCD LM17DB (17"), and the graphics cards is an ATi X1300
256MB, with the latest drivers...

I think the problem may have to do with PAL. Just a thought?

I've just discovered it says no signal detected when it realises it is not
running on the Dell monitor. Would I be correct in thinking it needs a
specialised driver to run on the tv? (Only problem being of course, one
doesn't exist - Who should I contact about this, Microsoft or the Monitor
Manufacturer, DM Technology?)

Did your TV come with a CD? If it did, maybe it will have the INF file for
it. Are you using a dual monitor setup? Is your computer connected to the
TV using a DVD connector or is it straight VGA, that is no DVI adaptor being
used?

Captain Roberts
 
I am using a DVI adapter, as straight VGA connection causes Windows not to
boot due to the graphics card. There is no CD/DVD with the TV so does anyone
have any suggestions as to what I can do get it to work??? Is there not a
default driver that ought to run? THough there are two connections, I am not
using a dual monitor setup, as to type this i am using a different computer...
 
Regardless of what model of TV it is, PAL-M is the Australian standard. All
video cards sold here in Australia with Super Video Outputs on them will
generate the standard PAL-M S-Video analog signal. It is possible that your
video card might have the option in the driver to change the analog output
signal convention. In this case, set it to PAL. The video card driver manual
will indicate any such feature if it exists.

With regards to using such an analog display as the primary/only display, I
have had no luck at all getting it to work in the past. I was using a GeForce
2 card at the time and I would assume things have improved since then.

My only advice would be to try and configure the S-Video display as a
desktop extension with your current VGA. If that works, try assigning it as
your primary display. Once/If that works, remove the VGA/DVI display as part
of the dekstop extension.

In the past, I have been able to get the TV as a secondary display. In an
attempt to use it as the primary display, booting the computer wouldn't even
show the video card or mother board BIOS graphics on the TV.

I'm not saying it can't be done but I will guarentee you one thing. If you
get it to work, you will be one proud individual because it's an up-hill
battle all the way.
 
Oh by the way, driver will make no difference in terms of composite being the
primary display. If you can't see the BIOS or Windows boot screen, it's not
driver related. If there was a fundamental screw up in the software inside
your video card, there might be a flash BIOS update for it. Do not update the
flash on your video card unless the update documentation actually indicates a
problem fix that you are experiencing.
 
The native resolution of your TV is 1024x768.
Is this the resolution you tried to use over VGA?
Have you checked the ATI Website to be sure you have the latest release of
the drivers for your card?
 
Yes, definately have the latest drivers. I have tried the native resolution
of 1024x768 but once again beyond the "knight-rider" style thing during
booting it says "no signal detect". I am using the DVI connection then
tranferring to VGA as using the VGA port alone means Windows refuses to boot
at all, saying something about having to use the digital output of the
graphics card.
 
But the OP is not trying to use the S-Video interface to his TV he is trying
to use the VGA PC interface which his TV also has instead.
 
Not in Australia, and I don't have an S-video cable with two "male" ends to
connect them up. I was under the impression that the VGA slot on the TV was
for PC input (sold as this). Like I said I can get to the BIOS screen all
that loads fine, it is literally the booting up of Vista when it stops
working. A thought I have had is that is it possible the Dell Monitor driver
is disrupting any would-be universal signal for the TV?
 
What does the Dell monitor have to do with the problem?
Do you have both the Dell monitor and the TV connected concurrently?
And if yes are you trying to run the TV as the secondary display in clone or
extended desktop mode? Also is yes what is the native resolution of the
Dell monitor?
 
No they are never connected together, but I have been trying to switch
between them - changing settings using the Dell monitor, and then plugging
into the TV, as I can't see anything on the TV so I can't adjust the
settings...

Any clue as to whether this is ever going to work, or am I just trying to do
the seemingly impossible?

Have you tried using both monitors, making the TV the secondary? This way
you can setup the TV to the correct aspect, and go from there. (that is if
you can get the TV to work at all. If not, then you will have to look into a
defective TV as a possibility)

Captain Roberts
 
I suggest that connect only the TV to your graphics card's normal VGA
output and do an F8 safe mode boot and the make sure the Windows normal
desktop resolution is set to 1024x768 and then try rebooting normally.
