Upgrading my fathers monitor...

[mojotunes]

my father just bought a large (for him) lcd moniter (sharp
LC-26SH12U). But when his "whiz-kid" son tries to hook it up to an
older basic pc/XP sys all I get is "NO Signal" from the new moniter.
This is making me look bad, any ideas? Converter box or what?
Thanks in advance-

Start in safe mode, then set refresh to 60 or 70. If previous monitor
was CRT, would be set to 80 or more. LCD cannot use that, hence no signal
message. What video card? What driver? Check if the video card CAN do
widescreen.

Problem is:
With an LCD monitor, "You can't get there from here!"
Even "Safe Mode" comes up with likely an 80hz refresh-rate.
Most LCD panels run *ONLY* at 60hz. So, "Safe Mode" doesn't help.

You need to start in VGA only mode, then set your monitor to 60hz LCD
panel, and reboot.

If the computer already has a monitor, and the 26" is an experiment,
you should be able to set the computer to sane resolution and
refresh rate using the existing monitor. Then swap monitors.
The tricky part will be getting the output of the video card
to run at the native resolution suggested on this page.
I don't see a monitor driver on the Sharp site, to help out.
(The monitor driver tells Windows the max res is 1366 x 768 -
note that the first number should be divisible by 8 while hooked
to VGA, and the second number divisible by 2. 1366 is actually a
crappy choice - options are 1360 or 1368 and using 1368 would
likely report out of range.)

A small number of video cards have HDMI connectors, and you can
also get DVI to HDMI adapter dongles. So you could also experiment
with the HDMI, but in fact the VGA is more likely to behave properly
(when you get it hooked up right).

I'm a bit curious about your symptom description. There is a
difference between "No Signal" and "Out Of Range". My monitor
will report "Out Of Range" on the OSD (on screen display), when
the refresh is too fast, or the resolution too large. I only
get "No Signal" if no cable is connected. Are you sure the
Sharp monitor is actually "looking" at the VGA connector ?
Do you have to switch to the VGA port by using the remote
control ? The "No Signal" suggests to me, that the LCD monitor
isn't even looking at the VGA connector. Maybe it is looking
at one of the RCA connectors ?

The resolution doesn't matter so much.
The refresh-rate *must* be 60hz.

Just remembered - had this and didn't know what to do. In the OSD there was
an option 'Native'; chose that and got a good picture.
