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.

So is it a Dell Inspiron 15R 5520 or a Dell Latitude E5520 ? – aliasgar Aug 31 '12 at 5:40

  • 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.

Well, the processor comes with intel 4000 gpu. Check here. – mtashev Aug 31 '12 at 6:31
So basically your on Intel 4000 Integrated Graphics. And you cant run analog and digital , ie: VGA and HDMI at the same time. – aliasgar Aug 31 '12 at 6:33

AMD Radeon 7670M с 1 GB DDR 3 собствена памет right? Still there is only 1 Graphics card, and still the same logic applies either VGA or HDMI. If u had a DVI and HDMI it would have worked as both would have been digital. Btw, a pro laptop guy says, it will still work on Intel 3000/4000, and there is no way to swap between the two adapters.
