Is it possible to connect 4 monitors to integrated and discrete cards at the same time?

Question

Video cards

Does anyone have experience organizing the display of 4 different windows on 4 monitors / TVs using both an integrated and a discrete card? Interested in the conditions of organization of work and the stability of the system.
Considered option integrated graphics card and 3 ports, discrete graphics card with 1 or 2 ports and output of 4 different windows (extended desktop)

Answer 1

I connected 4 monitors to the integrated one (3 FullHD + 1 2.5K), the fourth in duplication mode. As a result, I removed the fourth, I use three.

Answer 2

Can.
But not all models of video cards allow this. Some even have 3 ports, but they only include 1 to choose from.
Do not forget that the load on the system is higher.
And if there is something significant (for example, 4 different videos), then the processor will need to be more serious.

Answer 3

Rumor has it that one of the two. Either integrated or discrete. What we chose in the BIOS, we use it. On the second in this case, a black screen. But perhaps a question of system specification.
