Can a Samsung Galaxy S21 Ultra smartphone be connected to a 49-inch ultra-wide monitor?

I want to start using my Samsung Galaxy S21 Ultra as a computer. I'm also planning to buy an ultra-wide 49-inch monitor that I want to display the Samsung screen on using DEX mode. I want to connect the phone to the monitor using a USB-C cable. I'm talking about a monitor having screen dimensions of 5120x1440 or something very similar, e.g. [Philips 499P9H](https://www.coolblue.nl/en/product/826182/philips-499p9h.html) . I haven't purchased the monitor yet because I want to know first whether the built-in video card of the Samsung Galaxy S21 is powerful enough to handle the resolution of a 49-inch ultrawide screen. Does anyone know whether this smartphone can handle such a widescreen? It needs to be able to fill the entire screen, not just part of it.
