I've just taken possession of a new Asus X515J, it's got a HDMI port and a USB C port, but the USB C port does not do video out.

Is there any way, using a fancy cable or add-on, to get this laptop to work with two monitors that I can use in an extended display configuration (rather than duplicates of each other)?

Any advice would be greatly appreciated.

If you're certain that the USB C port doesn't support DP-Alt (as that's what most of the USB C hub/display extenders rely upon), then your other option is to use the USB 3 port and something like this:

I used a cheapy £30 USB A to HDMI adapter on a laptop that was a few years old. I never tried gaming but it was fine for office type use, web browsing, even YouTube. Windows just saw it as another monitor on the output preferences, so I could extend the desktop and didn't need to install any third party stuff.
J5create is the brand on mine, but I suspect there are many coming out of the same factory with the same hardware and price.

Thanks, guys.

I run a 2k monitor, so it looks like the one linked above will limit me to 30Hz! eek Hopefully, it should still be OK for office applications.

I'd question the value to be honest.

I used to try and drive two monitors off a lightweight Lenovo that did have two USB-C ports that supported video, but even so if I tried to present in a Teams call, the whole thing would collapse into a stuttering mess!

After 6 months blaming my poor, innocent broadband, I figured out that the laptop just couldn't cope with trying to run everything across three screens. Work got me a much chunkier mobile workstation which has as much memory on its GPU as the previous laptop had in total, and I've never looked back! smile

That's interesting to note, but I'll need to give it a go, as this is the laptop provided by my new employer.

If, after spending £45 on an adapter I'm still struggling, then I'll have that conversation with them.
