[SOLVED] Get 144hz video output from a laptop with 144hz display

[I Mess With Windows]

Hello,
I have an HP Pavilion Gaming laptop. It has a 144hz screen that feels pretty nice when playing. I have absolutely no external monitor for now, but as I repair a lot of stuff I am going to need one. As I am buying a monitor, I also want to use it for gaming, which is why I want to buy a 144hz monitor. The thing is, I want to be able to connect it to my laptop and get a 144hz output at a Full HD resolution. My laptop has HDMI and USB C. As I am running Windows 10, do you think a USB C to Displayport cable would get me that 144hz output, or even work at all? Or could I just use the HDMI output from my PC to either connect it to an HDMI input of a monitor, or use an HDMI to Displayport cable, to get 144hz?

You should check the HDMI revision on your laptop and a monitor that could do 144hz+ on HDMI. USBC and Thunderbolt 4 is the same interfaces but different on many things. if your usb c supports thunderbolt 4, then it could output a display.

does the usb c have display alt-mode?

I have found on the internet that the USB C port of my device wouldn't output any display, however I have HDMI 2.0, which supports 1080P 144hz. The only concern now is the 144hz monitor I will buy only supporting 144hz with its Displayport input. I have heard this could happen. So what if I use an HDMI to Displayport cable?

So, technically, any HDMI to Displayport cable that has at least HDMI 1.4 could be used for 144hz 1080P?

Also, if a 144hz monitor has HDMI 1.4 or newer, 1080P 144hz is fine by its HDMI?

Ok sorry I didn't know about this. I did a lot of research and this is exactly what I came up with. It means that I need to use the displayport to be sure I will get the 144hz refresh rate. However, my laptop only has an HDMI output. It is HDMI 2.0, and the laptop screen is 144hz, so I see no reason why this HDMI couldn't output 144hz. I am going to do more reseach about that.
I am going to need an HDMI to Displayport adapter anyway. And one that can give me a 144hz refresh rate at 1080p. Where can I find a such adapter online?

As part of your research into the capabilities of HDMI, you may also wish to read sections 5 and 5.1, since it explains very clearly exactly the information you are looking for.

I found the adapter on Amazon. It seems to be capable of doing what I need, so I will order it tomorrow. According to the document, any displayport version is fine for 144hz 1080p, so I can use any displayport cable as long as it is decent quality.
