I have a DELL 5520 notebook. The machine has two graphic cards working together (intel 4000 and radeon 7670).
I'm trying to connect it to two external monitors. I also tried to set it up to 1 monitor and 1 TV at the same time. The result is the same 2 out of 3 are working.
So, i'm connecting the monitors to VGA and HDMI port. However only one of them is working or in the case that i close the lid of the notebook, then the 2 externals are on.
In the company there are guys which already set their laptops with two monitors without external hardware and they gave it a shot, but it doesn't seem to work.
Any ideas on how to accomplish this?
P.S. It's a DELL Inspiron 5520 15R (i7 version).
Apparently it's not US spec, so it HAS intel 4000 gpu and it HAS Radeon 7670.
Here are the specifications for the Dell Inspiron 15R 5520 (All Models)
The New Inspiron 15R Special Edition has an AMD Radeon™ HD 7730M 2GB, but again that's all it has. Does NOT have two cards.
Your laptop does NOT have 2 graphics cards.
And when you run a monitor on VGA (Analog) and HDMI (Digital) any one can run at a given time. Analog and Digital will not run at the same time. More information here.
You will need external hardware to run it simultaneously.
