Problems with DVI Cables


Recommended Posts

Hey Guys and Gals, Long time no see.


So as you've probably guessed from the title I've been having a little trouble with DVI and VGA on my computer.


For about two months now I've been trying to get my Xbox to be plugged into my monitor through VGA using a small converter (which works perfectly fine http://amzn.to/1hXaADK) and to have my computer plugged in using the DVI port on my Monitor so that I could switch between the two by pressing the button on the bottom of my monitor for input.


My Graphics Card is the Nvidia GTX260 which has two DVI-I outputs on the back which if i understand correctly is supposed to support digital AND analogue, My monitor is an Acer (Not sure which one, can't see a serial number) which has one VGA slot and one DVI-D slot.


To try and get this system to work I bought a DVI-D cable (Male to Male: http://bit.ly/1hXbXCk) but when I plug both ends in and turn on my computer I see the motherboard logo and BIOS options and then does the Windows XP Loading bar at the bottom by itself even though I have Windows 7, and then after that the screen goes black and shortly after the monitor decides there's 'No Signal' although I can hear the Windows start sounds. And of course the Monitor goes into sleep mode which is infuriating. 


I've tried starting it using the VGA cable then switching to the DVI-D Cable but to no avail. Oh and I almost forgot I have a few DVI-I to VGA converters lying around which is what I'm using temporarily until this gets resolved. 


Screen Resolution: 1920x1080 60hz


Hope you guys can help me!


Oh and please put it in simple form so I can understand it better because I am yet to receive my degree in Computer engineering ;)

DVI to VGA is A-OKAY. I'm all for adapters!


But just in case people don't know the progression of technology, DVI is newer than VGA and using a converter from DVI to VGA negates the fact that it's plugged into a DVI output (i.e. the screen now sees that connection as VGA). Same thing with HDMI<->DVI<->VGA or any way you do it; The chain is only as strong as it's weakest link.


If you're able to visually determine a difference between VGA and DVI (even HDMI for that matter), congratulations .. you've become a robot! Though there are newer technologies, they only add support for wildly larger resolutions and wildly high refresh rates on wildly expensive hardware. Nearly all normal, gaming and even newer workstation monitors will not need anything above VGA.


On the software side of things: You're likely getting an XP boot screen due to your motherboard--for one reason or another, choosing on-board graphics over your dedicated graphics card. I'm not positive but in lieu of the Windows 7 logo, it may be loading safe graphics for diagnostic purposes.


On the hardware side of things: DVI-I, DVI-D and DVI-A are all impossible to interchange as the pin arrangements differ. So if it fits, you've done something right!
