[SOLVED] Getting 240HZ on External Monitor from Laptop?

[Doy5]

I recently purchased a gaming laptop and a 240HZ External Monitor. The problem is, the laptop doesnt have anywhere to plug in a DP cord, but the monitor does. I was wondering what cord/adapter I would need in order to be able to run my external monitor at 240HZ, because it doesnt look like HDMI 2.0 will get 240HZ to the monitor.

Thank you. This will allow for 240HZ on the monitor, even though the cable says "supporting 60HZ" in it?

cable says 8K at 60Hz
DisplayPort 1.4 is 1080p 240Hz compatible

Forgive me but I dont see a single reference to 240HZ on this link?

u wont find it, as they always just say max supported resolution @ which Hz it can go
so u have to do some math there
bandwith calculator

1080p @ 240Hz 8bit:
bandwith per channel - 5.94Gbps
total signal bandwith - 17.82Gbps

1080p @ 240Hz 10bit:
bandwith per channel - 7.13Gbps
total signal bandwith - 21.38Gbps

1080p @ 240Hz 12bit:
bandwith per channel - 8.32Gbps
total signal bandwith - 24.95Gbps

displayport 1.4 :
max bandwith per channel - 8.1Gbps
max total signal bandwith - 32.4Gbps

as u can see, it fits without any need for DSC compression

if u choose another cable (usb c to displayport) then mentioned above, make sure it supports displayport 1.3 or 1.4
as dp 1.2 cable can handle just 8bit 1080p @ 240Hz (21.6Gbps max)

Thanks for the clarification. My laptop and cords will be in today, so hopefully it all syncs up. I ordered this one https://www.amazon.com/gp/product/B07R3ZQBS6/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1

I'm probably getting ahead of myself, but someone mentioned my laptop didnt support Thunderbolt USB-C to DP in the Amazon review section...if this is true, is there a USB-C to DP cord thats not Thunderbolt? If that makes sense? Because if there is, I cant find it. Thanks again!

thunderbolt 3 is 40Gbps connection, u wont need it
what u linked support both usb c to dp or thunderbolt 3
