very strange monitor question

WhiteWashMan

oooooooookay.....

so i got myself a beautiful new BenQ 19" monitor.
really, its a work of art. its beautiful. everything runs fab on it.

heres the funny thing...
i try and connect my monitor using DVI, and my wireless connection stops. dead.
i switch it to 15 pin d-sub connection, wireless works.

i sh1t you not.
all i have to do is change which connection is used in the nvidia properties (im using a 5900 nvidia something or other) and the wireless just stops.

i have no idea why.

does anyone have any light they can shed on this really bizarre situation?

Is this a laptop? Could be power related... otherwise try changing the wireless channel?

WhiteWashMan

not a laptop.

will try changing the wireless channel, although i am unsure how that would effect things.
of course, i have no idea how agraphics card can stop wireless working anyway!

i mean, it still receives signal, it still says its connected, its just wont transmit anything and i lose my ip address.
have upgraded drivers on network card, graphics card and monitor....

Any chance that the graphics card has a firewire connector which is being activated as a network card when you change something in the properties and thus overrides the default wireless connection?

I'd say there's somewhere about 0.6% chance of that being possible, but I just thought I'd throw that out there.

WhiteWashMan

no, i dont have any firewire stuff at all.

ok, having done some more troubleshooting, this is what ive found.

when i turn on the dvi in the GC options, the ip adress is not lost. it just seems to stop accepting a signal. at first i thought there may be some sognal interference, but the signal strength is excellent, and it is still telling me the name of the network. so thats all good.

it just seems that it stops processing info over the wireless network!

im going to wsap out a network card from work and stick that in and see if it works.

i mean, worse case scenario is that i cant use DVI, but at even at 8ms response time, and testing it with Domm3, the picture is so pretty! no blurring or image ghosting or anything.
but since i really wanted to get the best out of it, i ordered one with DVI, so id obviously prefer to use that.

by the way, no overlapping IRQ's or memory addresses or anything.

i think it may just be one of those really crappy bugs with the hardware, so hopefully putting in something different will sure it. if not, then there realyl is something bizarre going on!

I'm almost sure I've heard of this before, I have a very vague fuzzy recollection of Intel based WNICs needing a bios update. If it is an Intel based network card you're using try looking up it's support pages and see if they mention it.
