You need a dual link DVI cable and capable video card to get 144 hz.

I did that...I don't get what it means by a dual link DVI port

you could google that too

ok so...i plugged the monitor into the dual dvi port but I just get "no dvi signal"

Check your DVI cable. See what one closely represents the one required for 144hz.

Note: Single link is capable of fitting most ports, and can be used in a Dual Link, but won't get the performance of Dual-Link. I think.

Also, you need DVI-D. I think. Off the top of my head, I think that's what my monitor came with. Typically more recent cards have ports that accept each of those cables. Just there's unique quality settings that can pass through the DVI-D/DVI-I that allow it to reach those settings. That's partially bullshitted and not even researched, but one does one and the other doesn't so I'm just making an educated guess.

I inserted it into the one but my monitor just says "no dvi signal"

So I read. Check the end of your cable and check the port(s) on your graphics card. Look up which cable is required to reach 144hz. Deep claims it to be Dual-link, so check to see if your Cable is both:

1.) Dual link.
2.) DVI-I or DVI-D.

Edit:

Witch some quick searching, your monitor should've come with a Dual Link DVI-D port. So one female port is correct, and you should have the proper cable. Look up your graphics card if you don't know what cables and ports it supports. It may not support Dual Link DVI-D.

Great so I tried to change the PCI (read it somewhere) of the video card...and now my computer won't turn on at all.

I switched the video card back to original PCI and it still won't turn on. Everything is plugged in.

Help!

why would you do that

did you turn it completely off before switching, i mean pulling the power cord etc.

Another thread instead of using google.

I think I had that problem once, I had to unplug my other monitor and plug my 144hz in the correct connection.

Ok so computer is fixed..monitor issue isnt

gather all your parts and return them.

go to www.ibuypower.com and buy a computer. seeing as you aren't even capable of utilizing google to do research on your seemingly limitless number of problems, you clearly are incapable of building a computer yourself.

Fucking dyz posting threads that he could just search for on Google again.

i think at this point hes making these threads to piss people off
