Monitor won't start when plugged into graphics card

[lowcountrysmoke]

How come my monitor will not start up when I plug it into my graphics card? I have been using onboard graphics and everything works fine. I recently bought a graphics card and when i plug the monitor cable into it the light on my monitor remains yellow instead of green. If i take out the cable and plug it into the mobo i get a display so somethings screwy. When the graphics card is plugged in all the fans spin and the led's light up ..but no monitor display. Right now i have my gpu in the pci slot but have my cable plugged into the mobo. I am currently using an old monitor that uses vga (until i get my new one, it is a gateway2000 vivitron..yeh lol) so i have to use an adapter that msi provided when i plug it into my gpu. Maybe something is wrong with the adapter? The adapter looks like it has missing pins but i think that is normal with vga- dvi a, the a stands for analog. Could this be it? Since my computer has been running fine for a month now playing games and such, i doubt my psu is bad (also the gpu is getting power like i mentioned earlier). I have tried to start up with graphics turned to pci express- still nothing, I have tried with and without drivers- samething.. I am stuck and not sure what the problem is.. Please help

Specs: msi 7870 hawk, i5 3570k, 600w cx corsair, asrock z77 pro4 and the rest is irrelevant.

from 4x to 16x I would say you are yes. Because your slot is only going to run at pci-e 2.0 4x speeds.

right, but does anyone know how much perfomance is actually lost bc of this? Im sure its not as much as some ppl may think

 

[lowcountrysmoke]

I dont know how accurate this is, but i read somewhere that 4x is just 15% slower then 16x. So maybe i will try to switch out the mobo sometime, but for now all my games are running perfect with great fps.

I found a older article it looks pretty considerable to me I would get in contact with ASROCK. No reason you should have a fully capable card and motherboard only to be held back by a weird slot.

Not much depending on the application and gpu used.

There are more lanes incorporated into the 16x & 8x slots feeding off the cpu controller whilst the 4x is using the chipset controller.

Benchmarks are hard to find quickly but did find a youtube video testing a 6990 in each 16/8/4 slot.

The scores aren't much different, but he did mention he'll have a more intense benchmark next time.

So guess for now you'll be fine, but if upgrading to a more powerful gpu in future could be restricted even further as more powerful gpus start to take full advantage of 16x.

Thanks for all the info and help guys! I really appreciate it, for now im just going to keep this mobo and maybe the slot will start workin...who knows 😗

Right but there is no reason why he shouldn't be able to take advantage of his motherboard's full purpose of him being able to run his card at full bandwidth I would talk to ASROCK and see what they say maybe there is a way for them to instruct you in changing your pci-express 3.0 to a 2.0 speed slot. Also maybe there is a bios update that would solve the solution

 

[bigshootr8]

That's fine but like I said I would talk to ASROCK no reason your board shouldn't be doing the work you put your money into.

 

[lowcountrysmoke]

Yeh, i will talk to them to see what i can do and if they have had any other issues like mine.
