dvi ports?

My graphic card which is about a month old has been giving me nightmares =\
ive tried everything, and i just wanted to make sure ive covered all the bases

my graphic card has two dvi ports. i only have the normal blue colored monitor cable, but the gfx card came with one of those converter things where i plug in my monitor cable into it, and plug the converter into the gfx port. however the other side of the cable is still connected to a normal monitor cable port, on my monitor. my monitor does have a dvi port, and i was wondering if i were to buy a dvi cable if my problems would disappear.

(have tried power supply, cables, etc. )

dottyness on my screen remains.

Hello u5cevryday,

Since both your graphics card and monitor has a DVI port connection, it would give you the best picture to get a DVI cable. You can get a 6' cable pretty cheap these days.

yeah i realized that but i was wondering if it was mandatory, and if connecting the monitor cable is known to cause problems?

Sorry for the late reply u5cevryday.

It's not mandaotory, but if you want a better picture, you will need to have a DVI cable connection on both ends.
