Cant make 3rd monitor work

[cxco2r]

So i got my hdmi cable, and connected it to my pc.

Right now i have 2 monitors connected with DVI and I just plugged in the HDMI one.

For some reason i cannot get the HDMI one working, i am getting the error message "to extend the desktop a desktop or display must be disabled",

I have no idea what to do now, i read about some adapters but i know nothing of that stuff so can someone explain this step by step to me.

Thanks !

What is your GPU.

Must likely it requires the 3rd display to be hooked up using an active display port adapter. Or it only supports 2 monitors

My gpu is AMD Radeon XFX 270x

What kind of adapter should i get ? I'm sorry but this is a first, i know nothing about this stuff

It will work with three without display port but the monitors on the DVI ports MUST be identical. So that's the first thing. what monitors are you using?

If you are using mismatched monitors you should be able to use a display port adapter to run one of the DVI monitors. Such as:
www.amazon.com/StarTech-com-DP2DVIS-DisplayPort-Active-Adapter/dp/B004SUO1GM

The adapter MUST say it's active. Not passive. For this to work.

You'll need two of these and an HDMI cable: http://www.newegg.com/Product/Product.aspx?Item=N82E16814999030

why two ?

It gets you off the GPU's DVI signal and onto the DisplayPort, which doesn't require matching displays. You can try one, but I'd recommend two so that you'll be on the best outputs with the fewest restrictions. Maybe order two from Amazon if possible, and then return one if it works with just one. Amazon has free returns.

Would this be alrighty ? https://www.links.hr/hr/adapter-delock-displayport-m-na-dvi-i-245-z-bijeli-200300217


Or this https://www.links.hr/hr/adapter-delock-displayport-m-na-dvi-i-245-z-bijeli-200300217

Not sure that one offers an active conversion, but this one does: https://www.links.hr/hr/adapter-delock-displayport-m-na-dvi-i-245-z-4k-crni-200300250

yeah, https://www.links.hr/hr/adapter-delock-displayport-m-na-dvi-i-245-z-bijeli-200300217 - the white version is available where i live, So this would work ?

Also dont need 4k

That means i would connect one DVI normally, one over DisplayPort adatpter and one over HDMI?

You should get an adapter that's active, which the one you linked is not. Here's an explanation about the difference between passive and active adapters, other than that active adapters cost more.

So this is my GPU, and it seems i need mini display ports as i dont have a normal displayport port. That is correct ?

okay found one. https://www.links.hr/hr/adapter-delock-mini-displayport-m-na-dvi-i-245-z-4k-crni-200300251

Yes, in that case, you'll want to go with an active mini DisplayPort to DVI, such as this one: https://www.links.hr/en/adapter-delock-mini-displayport-m-na-dvi-i-245-z-4k-crni-200300251

I also found this one. https://www.links.hr/hr/adapter-delock-mini-displayport-m-na-hdmi-z-4k-crni-200300253
It is available where i live. But this one is for HDMI. That means i can use that one for hdmi and leave the DVI ones without adapters

 

[Eggz]

You can try that. I think it would work if you have an HDMI on your monitor. The goal is to get everything onto the DisplayPort and HDMI ports from your card to limit restrictions.

I have 2 monitors, DVI connected and a TV with HDMI. The TV is connected right now but you know the drill. Remove one display bla bla bla.

So i think this adapter should do the job just fine.

 

[Eggz]

Worth a shot. I'd still buy two of them, see if one works, and return if so. But if you need two, you'll at least have them on hand without having to put in a new order and then wait for a second delivery.

I'm having a similar issue...I'm trying to connect 3 identical monitors (DELL E2414HM) to 2x 6950 2GB in crossfire I'm using 1x VGA to DVI-I, 1x DVI -D to HDMI and 1x DVI-D to HDMI connected to HDMI to minidisplayport(RuiLing Mini DisplayPort to HDMI Active Converter MALE to FEMALE). Only the 2 DVI connected monitors are registering, it shows the VGA in display/screen resolution but says disconnect this display. When i try to change to extend this display it gives error stating can't save the settings...Please help this is driving me nuts....
