I’ve been wondering if my laptop can support a monitor that runs 120-144hz. I have a ASUS ROG G531GT.
Processor: Intel Core i7-9750H CPU @2.60GHz
RAM: 8GB
Graphics card: NVIDIA GeForce GTX 1650
Ports:
1 x Type C USB3.2 (GEN2) support DP function (GU/GV/GW)
3 x Type A USB3.2 (GEN1)
1 x HDMI 2.0b
1 x 3.5mm Audio Jack/ 1 x Audio Jack Mic-in (Combo Jack)
1 x RJ45 LAN Jack
even a desktop gtx 1050 was able to run more than 100 fps on low settings.
So if you turn down all your settings to low, which i always recommend even with better graphicscard, you should be able to run more than 144 fps.
i would recommend you to buy a monitor which is listed as suported monitors for freesync. So even if your laptop dont reach the 144 fps you get a smooth exoperience.
My previous laptop had a i7-7700HQ and a GTX 1050
was able to run at 120 FPS easily, though I had to drop the resolution down to 900p
make sure you use a USB-C to DP cable (I plugged mine into the thunderbolt 3 port)
I mean can I get 120-144hz on a monitor even if my laptop screen is capped at 60hz without a DVI port
almost no one uses DVI anymore. Use DisplayPort (USB-C/Thunderbolt also carries DP)
dvi does not even support 144hz. you have to use a duallink cable. just get a usb c to dp cable. thats it.
It should work. I have hooked my old 85Hz CRT monitor to the VGA port and it was fine.
Edit:
Wait. You have or don’t have dvi port?
Do not have a DVI Port. The ports I have are listed above 
It depends primarily on bandwidth, and HDMI 2.0b would be more than sufficient for driving 1080p or 1440p at 144hz, and probably even 240hz. I dont know offhand about 4K but I would not recommend trying to do 4K gaming on a laptop anyway.
Do I have to find a specific monitor that wont limit to 60hz through HDMI? And are they hard to find?
The monitor has to support a version of HDMI that has enough bandwidth to drive it at the particular resolution, yes.
Generally the monitor specifications will call out if it doesnt have enough bandwidth over the HDMI port. I’ve seen this most ocmmonly on early 4K monitors which could only end up doing 30hz (versus display port that could do 60hz) but I dont think ive ever seen a gaming monitor designed with that restriction. I would expect pretty much any 120/144hz display you find would be compatible.
Do you mind on adding me on discord to discuss this? Clapped#9175
Yes easy, just make sure that the monitor itself supports 144hz on HDMI (most newer models do as far as I’m aware of)
I do not have discord, sorry. I’m happy to answer any questions here to the best of my knowledge though.
Do you think you could help me find a reasonably priced monitor that supports 144hz at 1080 over HDMI?
well, anything can “support” a 144hz monitor…
IF it has the right ports for it.
for 144hz itll need either a Display port or a DVID port, and i don’t think conversions would work with that. (not 100% sure tho)
As for if it can get to 144fps in game, well it should get around there.
You can probably start here:

I would be extremely shocked if any monitor you can buy today couldn’t do 1080p@144 over HDMI, so it would almost certainly just come down to finding the right size and panel type you want.
You can check the specifications to be sure, but I believe anything HDMI 1.4+ is sufficient for 1080p and 144hz, though from what I’ve quickly read, gsync specifically caps HDMI at 60hz so you wouldn’t want that.
For example, this page has a few decent Q&A’s that could be helpful:
However, I’m also re-reading your specs and you actually did point out (which I missed) that you have a usb-c port with displayport. In that case you should only need a small adapter for usb-c->displayport and that should support pretty much everything.
For panel type you can go with one of the following:
TN: Faster response times and generally the cheapest, but worst image quality
VA: Middle grounds in terms of price and image quality and is known for good blacks, but generally highest input latency.
IPS: Best in terms of image quality but highest price and higher latency than TN, but probably fine for most folks, especially on a gaming grade 120/144hz panel.
