GPU: Sapphire Vapor-X R9 280X
Monitor: Iiyama Prolite E2473HS
TV: Older HD tv from samsung with a thick layer around it

Hey guys, I have a bit of a problem and i need to find out what is going wrong.

I have my main monitor (Iiyama Prolite E2473HS) connected with an HDMI into my GPU.
now i came to this glorious idea of connecting the monitor with a DVI into my GPU and connect my TV with HDMI into my GPU.
but when i do that my TV acts as the main display and my monitor doesn't respond at all (it goes into standby mode right after turning it on) and i tried to switch main displays but then my computer is the only thing running.

i also tried to connect my monitor with DVI into the graphics card, but then it (the monitor) goes into standby after turning the monitor on. and when i put HDMI in again it works.
and now i'm clueless

Any help is appreciated;)

All modern graphics cards(Besides the Sapphire FleX series) only generate 2 clocks to sync monitors together.
That's where DisplayPort comes in.

To run more than 2 monitors(or combinations of tv/monitors),one of them must be connected through DisplayPort OR an active DisplayPort Converter.

I.E
Active DP Converter ->HDMI going to your monitor
HDMI going to your TV
DVI going to your other Monitor.

Thanks for the answer,
So this means i need to buy a HDMI to Displayport converter, before i can activate dual/triple monitors?.
Then i just buy a HDMI to Displayport converter, plug that into my Displayport port in GPU,
get the HDMI from GPU to TV and it should work?

As someone who has little knowledge about this it seems pretty weird to me that you cant just plug DVI in and go. (because for people like me, a cable is a cable and if you plug it in you pretty much expect it to work)

I have my monitor connected through DVI and my TV through HDMI so it works.

Try holding the Windows key and pressing P. Select "Extended". This is how my system is set up and it works perfectly.

You can have 2 monitors without display port,but to have 3 monitors,one will have to be Display Port or be hooked up with an Active Display Port converter.

In your first post, you stated that the monitor by itself does not work on DVI, right?

If this is correct, then it likely means a part is bad. It could be the DVI port on the video card or monitor, or it could be the DVI cable itself.
To find out which one it is, use a process of elimination until you can determine for sure which of the 3 it is.

* Try the monitor and DVI cable on another computer.

Try another DVI monitor (and the same DVI cable) on the same video card.
> If it works, then maybe the first monitor's DVI port is bad.

Oh dude, after i read this i tried it on my older PC, and cable didnt work. but i also never used a DVI cable (only VGA on my old monitor and HDMI now) but i found something out now.

The 2 DVI slots into my GPU are for DVI-D (Dual link) and a DVI-I (dual link)
the cable i used is a DVI-D (single link with a gap in the middle)

it might be a stupid question but is this the problem? that i need to buy a dual link DVI-D/DVI-I
or is there a problem within my Monitor?


OH wow guys, i cant believe im this stupid, so i bought a new DVI-D dual link cable instead because i thought the cable was broken, then it didnt work and i was so mad i was looking into bios terms and things, now i rembered i had a menu on my monitor i can pop up, seems im too used to the fact that when i plug things in i expect them to work but i had to choose manualy on my monitors menu WHICH sort of connection i was going to use, so i need to select either HDMI, DVI or VGA and all sorts of connections, and now it works! just by selecting the DVI connection on my monitor;S
cant say i bought the cable for nothing now because if i will ever get a second monitor i have another DVI cable now:D 
stupid me.

thanks for the help guys!
