External screen won't detect

[Paige_]

I have a Toshiba satellite C850 laptop that won't detect nor connect at all what so ever to my TV as an external screen via hdmi or vga cable. Please help Its obviously my computer but I don't know how to fix it

did you select on the tv the video source as "pc" not cable or sat dish?

Yeah I had it set to pc for the vga cord and set to hdmi 1 for the hdmi cord neither worked.
When I go into display settings on the computer and click detect it doesn't do anything at all. It doesn't even come up with multiple display options underneath

the pc setting on the tv was also for the hdmi besides the vga?

Still blank blue screen with No signal

 

[ffg7]

do you have or can borrow a monitor to plug into the laptop?

No, I just found in the device manager folder that the display adapters section that the Intel(R) HD graphics had a yellow triangle with an ! In it
Said it wasn't working because it may have been corrupt or missing something so I rolled it back to thelastdriver maybe that might help

 

[ffg7]

try it.
