Cold monitor horizontal sinc

[u_rebelscum]

My monitor is acting "fuzzy" when cold (under ~60 degrees F).  Once warm, it's fine.  The colder it is, the longer it takes to go away.  The operating manual says operating temp is 0-35 C (32F minimum)  I have an old iiyama 17" MT-9017E (diamondtron) minitor.

At 59F ambient, the symptoms go away before bootup is finished; at 55F ambient, it takes ~3 minutes total to go away.  I'm sure the length will be longer as winter gets cooler.  Lucky I'm on the west coast so it doesn't get too cold.

It appears as if the horizontal sinc does not work line to line per frame, and frame to frame.

My computer is in an unheated room because that is the only place to put it.  Also, I can only test the problem once per night, since once the monitor warms up, in goes away.

It's not the cord, because I tried using the BNC and normal VGA HD-15 video inputs, and both get the problem.

Anyone have had simular problems?

BTW, any free .mov file editors anyone would recomend?  That's the format my digital camera outputs.

thats exactly how my monitor looks after switching back to monitor with TV-Tool.
it gets slightly better after a few minutes but wont quite go away.
only a reboot fixes it.

Hmm, I wonder what the cause is for your computer?  It might be related, but I don't think it's the same.  Mine goes away to crystal clear after the monitor warms up, and the colder it was at power on the fuzzier it is and the longer it takes to clear up (in average).

It's still a great monitor after the 4 (IIRC) years I've had it, and would like to keep using it if possible.  I wonder if I'm damaging it a little every time it fuzzies like that.
