The thing is i just have two usb c thunderbolt port and one usb 3 port

So you said that the built-in monitor count as one screen right ? so i am limited to just two external screen ?

Isn't there a way around it ? i heard of monitor that you could plug on usb who wouldnt take a slot on the gpu is that right ?

thunderbolt port and usb 3 port is not for the connecting screen . EDP monitor is counted as one screen .

In my laptop , additional ports are VGA and HDMI 1.4 , so I can able to connect , Currently two monitors are working . HMDI monitor is not available .

For more information , visit intel support website

The Intel HD Graphics engine in your processor supports a maximum of three monitors. Considering the internal LED display, this means that only two external displays can be supported.

 

It is possible to add support for additional displays by adding an additional graphics engine. In a laptop, the cost-effective way to connect an additional graphics engine is via USB 3.0. Here are some examples of USB 3.0 graphics adapters:

 

 

The alternative to using USB 3.0 is to use a eGPU connected via Thunderbolt 3 (USB-C connector). This is a horribly expensive alternative; one I would not recommend unless you want to do heavy graphics work or gaming. It requires a special external PCIe graphics enclosure and an AMD or NVIDIA add-in (PCIe) graphics card. Here are some examples:

 

 

Hope this helps,
