Render complete tilemap with scaling

[Dreaded-Gnu]

Hello,

I've a small tilemap with 50x30 tiles. Each tile has the following size: 32x32.

What I want to achieve is that the client renders the whole map. This means, that the map needs to be scaled up on large devices like my notebook, and scaled down on small devices like my smartphone. Is this possible with phaser or am I trying to do something that isn't possible?

I already tried various phaser scale modes, which had no effect at all.
