webcamtexture not able to set resolution

 private WebCamTexture webcamTexture;
     
     void Start()
     {
         
         WebCamDevice[] devices = WebCamTexture.devices;
         if(devices.Length > 0){
           webcamTexture = new WebCamTexture(devices[1].name,1920,1080,30);
           webcamTexture.Play();
         }    
         renderer.material.mainTexture = webcamTexture; 
         webcamTexture.Play();
    }

I have 2 cameras - a crappy built-in and logitech c920 (full hd) I want to use that one for the video stream. The funny thing is that when I try to run that as it is here the camera starts to blink and the game freezes until i unplug the camera. When I use

 webcamTexture = new WebCamTexture();
 webcamTexture.deviceName = devices[1].name;

instead of

 webcamTexture = new WebCamTexture(devices[1].name,1920,1080,30);

it works albeit in low resolution.

What should I do?
