dev is right. I've never come across a monitor that is capable of high refresh rates over HDMI...

You probably know this, but just in case: Any laptop with thunderbolt / usb-c would work too. But hdmi doesn't have enough bandwidth iirc.

newer HDMI protocols do support 144hz, but no monitor seems to

So a laptop with USB-C/Thunderbolt, NVIDIA GeForce plus an external monitor would likely be just as good as with DisplayPort? I think that would make it easier finding a laptop.

Yes, my MBP only has usb-c, I use a usb-c-to-displayport cable to the 144hz monitor.

Does the monitor function at 144hz using this adapter? or is it limited to 60hz?

No, I run QW at 1080p @ 144 Hz ... Displayport via USB-C is a thing, it works fine: https://www.displayport.org/what-is-displayport-over-usb-c/

that is cool. I know if you want to convert from DisplayPort to DVI you need a special expensive 'active' adapter in order to get higher refresh rates... it is not great at all.

What you have doesn't appear to be a converter but rather just running one protocol over another port. very cool.

Thanks, that helps.

Yes, they've done it right with usb-c. It's gonna be the go-to-protocol for everything for a decade.

Can Apple phones with thunderbolt and other phones with usbc push 144hz? I suppose the chips don't support that?

Like an iPhone running an external 144Hz monitor, you mean? No idea. But the usb-c won't be the problem. (Though iPhones don't have usb-c anyway, but lightning port, iirc, not sure about displayport protocol compatibility or bandwidth limits on that.)

Ah, you confused me a little with this quote, I guess you mean that thunderbolt laptops have usbc, not about thunderbolt to dp adapters working or existing.

Do you think a Dell XPS 15" would be fine? It has Tunderbolt and a GeForce GTX 1050. The only real game I need it for is QW - otherwise just surfing and general regular use. It would be nice with the 13" but it does not have a GeForce.

Yes, that should work fine, afaics that is the same Thunderbolt port I have on my MBP.

You can use a cable from the USB-C port to the display, like I do (I got this one) or you can get the Dell docking station and use a standard displayport-to-displayport cable.

I run QW at 1155 fps from the MBP to the 144 Hz monitor. The GTX 1050 in the Dell will outperform this by miles.

Not really sure what you're asking, but: Thunderbolt and USB-C use the same connectors, so any cables or adapters that fit one will fit the other. If say a Thunderbolt to Displayport cable will work, from what I can see, depends if the Displayport alternate mode is supported by the hardware in the laptop. The Thunderbolt ports on the MBPs and Dell XPS, for instance, supports the Displayport alternate mode, and a cable like this will be fine.

First of all, iPhones have Lightning port, not Thunderbolt/USB-C, so they won't. For smart phones with USB-C, it depends if the manufacturer has built support for all the possibilites the USB-C gives, like Displayport alternate mode. Samsung Galaxy S8 does support DP alt mode, and from that I've googled, it can work fine like here, and it can be buggy. Those tests don't mention anything about refresh rate, though.

MBP = MacBook Pro?

Does that have the Intel Iris Plus Graphics?

Yes, but I have the one with Radeon Pro 560.
