Question 3 Monitors - AMD R7 200 Series

I am using a rather old Graphic card from the AMD R7 200 series. Graphics stats and my PC ports:
From previous threads on this forum, I found out that some of those R7 200 series card may support 3 monitors only if at least one of the 3 monitors is using a DP (or mini-DP port), or that max 2 of them can be non-DP ports. Therefore I went a boguht a mini-DP to HDMI cable. I went for the mini-DP because I dont have normal DP port on my PC.

So this is how i tried to connect the monitors:

1x DVI to VGA adapter
1x HDMI to HDMI
1x Mini-DP to HDMI adapter

Although, i only got max. 2 monitors to work at the same time, but on my display settings I were able to see all 3 monitors, although I still can't get a picture on the third one.

Could it be that the mini-DP cable is not allowed to have and HDMi ending?
Must it be "DP to DP" in order to count as a DP port? I were thinking that only the port that actually goes into the PC matters.
 
On that old card you can only have a limited number of digital connections. Most likely in order to use all three you will need an "active" HDMI or DP adapter, not just a regular passive adapter. Active adapters are expensive by comparison.

A lot of older cards had "clock" limits so that only two "clocks" could be used and an active adapter of some kind was necessary to add an additional "clock" for a third monitor. Pretty sure your R7 series is included in that.

First of all i'd like to thank you for your quick and detailed answer.

I had ot look up the difference between an active and pasive adapter, and Im sure the one i boguht is an active one, since i do have the "box"

" Basically, if the adapter includes a little box that houses the conversation chip it is active. If the adapter cable is no bigger than a regular plug, it is most likely passive."
Is there any way to fin dout of my specific graphic card can support 3 monitors?

This is the thread i was referring to earlier:

 
i had 3 with an r9-270 with no problem. think it was 1 vga, 1 dvi and 1 hdmi port if i recall right.

worked fine. never had a 240 though so it might be different. don't think those old cards even had dp ports but i could be wrong there.
They got mini DP ports - which I can use. its just that i cant fix 3 monitors, like explained in the thread i mentioned earlier

Where'd you get "R7 240" from? All I see is R7 200 series, which TechPowerUP seems to think it is not that card based on it's hardware ID.

According to TechPowerUP, that card is actually an HD 7770 which is PART of the R7 200 series family only because they are all based on the same architecture and have many similarities. That is based on the Device ID from your screenshot above.

What is the ACTUAL model, as printed on the sticker on the graphics card itself? Can you post an image of both sides of the card AND the back of the card where the outputs are at?


 
Active DP adapter required. Please see here:


If you didn't specifically look for an active adapter when buying, then your adapter is most likely passive.

" Basically, if the adapter includes a little box that houses the conversation chip it is active. If the adapter cable is no bigger than a regular plug, it is most likely passive."
This is wrong, the way you determine if an adapter is active is by reading the product description and seeing if it says it's an active adapter. If it doesn't, it's a passive adapter. Physical form factor is not a reliable method of identifying them.

for whatever reason all those cards only listed as 200 series. my 270 and a 270x i had at one point also showed as 200 series. not sure why they did that but it def caused a lot of confusion and still does.

so def posting a pic of the card would be a good idea so we can know for sure what you are dealing with.

Exactly what I was going to say yesterday, and forgot to include, was that it's probably NOT an active adapter if you didn't specifically buy a product that says it's an active adapter. Active adapters cost about three times the price of a really good passive adapter or cable, at least, so if you didn't specifically make sure it was active, it's very doubtful that it is.

Thanks all for the repleis!

Its actually a HD7770: View: https://imgur.com/a/wRfLg8Y


Regarding the adapter description, it weren't mentined if its active or passive, neither does it say on the webshop.

The part with the "box" I've found online, while searcing for the difference between active & passive ones.


Regarding the price, the one i bought were 14€, while active ones actually cost 45-50€, so im sure mine isnt active.

To sum up: replacing this passive adapter with an active could actually get the job done with my card?

Yes. The 7770 is one of the cards as described here.
