Does Connecting a Monitor to Gaming Laptop Increase Refresh Rate?
A common question I get is “If I have a 60Hz laptop screen, can I use a faster monitor like 144Hz?”
The answer is yes! You can play games on a monitor with higher resolution and refresh rate (Hz) compared to what the screen the laptop came with is capable of.
If you connect an external monitor to your laptop, the monitor can run at the maximum refresh rate that it supports. The refresh rate of the laptop’s screen is not relevant, it does not matter.
The caveat is that the way you’re connecting the laptop to the monitor must support the resolution and refresh rate of the monitor.
For example, HDMI 1.2 cannot run a 1440p monitor at 144Hz, however HDMI 2.0 and newer can do this just fine.
If you’re connecting a monitor to your laptop with HDMI, refer to this page to see a list of what HDMI versions are needed to support different resolutions and refresh rates.
If you’re connecting a monitor to your laptop with DisplayPort, refer to this page to see a list of what DisplayPort versions are needed to support different resolutions and refresh rates. Type-C ports use DisplayPort, so check this if you’re connecting with a Type-C cable.
People want to know if they buy a bigger, faster, expensive screen if it will be limited by what the laptop screen runs at. The resolution and refresh rate of the laptop’s screen is not relevant. It depends entirely on what the external monitor you’re connecting supports, and whether the display connection (port) supports the resolution and refresh rate.
Hey Jarrod! I need ur help. I bought a lenovo legion 5 pro laptop after watching ur review. N with the help of the lenovo tech team I updated each n every thing including the drivers on the laptop. But since I never had a gaming laptop before I don’t have anything to compare it with. My problem is that I’m facing some aliasing issues in asphalt 9 n valorant n idk if it’s the game’s issue or the laptop’s. Also, because of that I started to look at every graphic detail more critically. N some of the smaller images like when I open the microsoft store n the thumbnails right below the big image look very grainy, like someone has turned the sharpness to the highest value. Idk if it’s how it’s supposed to look or if there’s something wrong with it. I tried to Google this problem to find out a way to test if the graphics r working as they’re supposed to. But all I found were the apps n ways to run a scan or check the graphic card. But that doesn’t make me feel confident about it. Because this is the second legion 5 pro I got delivered. The last one was malfunctioning n the tech team n the engineer were unable to detect what was wrong with that. In all scans it showed the laptop was working fine as per design. The graphic card was working fine. N yet it kept crashing the moment i tried to play any game. So those scans don’t make me feel secure with my purchase. Is there a way u can tell me I can check if the graphics on my laptop r the way they’re meant to be? Or if u could tell me if those images look as grainy n sharp on ur laptop as they do on mine? I know ur a busy person. But idk who I should ask other than u to help me. Cuz the tech team said they can’t help me with it. They can only act on what the scans r telling them. Also, if u could tell me if the 1 sec delay between the left click n the refresh menu to pop up is normal on a brand new gaming laptop, that would be a great help.
Are you running the games and Windows at the native screen resolution (2560×1600)? I’d manually get the latest Radeon driver for the integrated graphics and Nvidia driver for discrete graphics and would expect things to be fine. There are some text clearness settings you can play with in Windows but not sure if that affects games. Not sure what you mean by refresh menu.
Thank u so much for replying. Yes the resolution is 2560×1600. N I’ll try to install those drivers manually.
About that refresh thing: when I was pressing the right mouse button on desktop, i thought in a brand new laptop the menu to refresh n other things would pop up the moment i released the mouse button. But it took a second to show. That’s why I was a little concerned. But now that I have used it a few times, some times it appears quickly.
Anyways, thank u for the help Jarrod!
It should be pretty fast, if those things don’t fix the problem might need a clean Windows install.
Hi Jarrod hope you do well, a question, for gaming purpose (mostly) and daily works , you’d prefer legion 5 pro 2021 with rtx3070 or 2022 5I pro with 3060 ? Imagine they are nearly same price in my country for my chose.
Haven’t used the new one yet so can’t say how it differs, for gaming I’ve shown that 3070 is about 15% better than 3060 here: https://www.youtube.com/watch?v=6asPkbTds3o hope that helps.
Ayo, Jarrod! I was wondering if I had a laptop with a 144Hz refresh rate for the screen, should I get a monitor with a less, equal, or higher refresh rate?
I was also wondering how I could figure out what a monitor could support and if the display connection port(s) supports 1080p FHD resolution and 144Hz refresh rate.
Also, if you don’t mind could you recommend a monitor that is fast but cheap (perhaps under $100, if possible) and is compatible with the Acer Nitro 5 AN515-57-5700?
Thanks in advance!
It does not matter from a technical perspective, it just depends on what refresh rates/resolutions the ports support. Personally I’d probably get the same or better than the laptop’s screen so it’s not a downgrade, but that’s just personal preference.
You want these pages, they tell you which version of HDMI/DP do what resolutions/refresh rates:
I don’t review monitors so don’t have any idea as to pricing, sorry. Maybe check out “Hardware Unboxed” on YouTube, they do lots of round up style content of monitors.
Ah, thank you for the information!
Hi Jarrod, big fan of your videos here, im from México and just purchased a asus tuf fx706heb f17, i play fighting games y liked the way laptops can offer to a local fighting community, im used to play on ps4 with a 10ms response time monitor benq rl2755h and i was wondering how much display lag /response time have the asus tuf f17 fx706hn because i feel a little lag on the laptop display. Thanks in advance for your repply
I haven’t tested the TUF F17 specifically so can’t say, but check my reviews for similar machines like TUF A15 and look at the screen timestamp, I have response time for the panel as well as LDAT graph which shows the latency (time between mouse click and action taking place on screen).
Hello Jarrod, I recently broke the screen for my Acer Nitro 5 AN515-57-5700 model and I was wondering if you knew where I could get a replacement screen. I haven’t found any online so it would be really helpful if you could help with this. Thanks!
The screen is a 1920×1080 LED-backlit Full HD IPS display.
The display screen type is LCD.
Other specs are on the Acer website. https://www.acer.com/ac/en/US/content/model/NH.QESAA.002
Use HWinfo to get the exact model of the panel and then look on sites like ebay/google to find someone selling it.
Hey jarrod, I have a lenovo legion 5 2020 with ryzen 5 4600h and gtx 1650. I’m thnking about getting an external gaming monitor of refresh rate 144hz, so does HDMI 2.0 support 144hz with g-sync?
and also does the USB type c 3.2 can be used to do the same?
HDMI 2.0 does yes, you can see what it offers here: https://en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_for_standard_video
USB doesn’t do anything in itself, the port needs to provide DisplayPort which is optional.
My son currently extends his gaming laptop to a 27″ non gaming monitor. He asked for 2 gaming monitors for his bday/xmas and the goal is to have both of them be extended so he can have both screens going (likely one 1 will ever be for his games while the other is for youtube/discord). Anyway, I want to make sure the signals to the monitors support the higher Refresh Rates. Any thoughts on the type of Hub that can support > 60MHz?
It all depends on the versions of either HDMI or DisplayPort being used on the laptop, dock and monitor. Take HDMI for example, this shows what resolution/refresh rates are supported with the varying versions. The lowest version in the chain will be the limit: https://en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_for_standard_video
I currently have a lenovo L340 Laptop with a 60hz refresh rate and has a intel I5 and GTX 1650. I am planning to buy a 144hz External Monitor. Can I use the 144hz refresh rate of the external monitor instead of having 60hz refresh rate from my Laptop. Like If I disabled the laptop’s monitor and set the external monitor as my primary one will I have 144hz on my external monitor? or it will still cap at 60hz? I also have an HDMI 2.0
Yes, HDMI 2.0 supports 1080p ad 144Hz and above, see here: https://en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_for_standard_video
Hey Jarod, I need an opposite from my laptop: I need either the USB-C DP or HDMI to connect directly to the iGPU. Specifically to an AMD APU.
My old budget gaming laptop did this, and maybe it was aweful for gaming on an external screen, but it’s a life-saver for running Linux on the laptop.
Now that manufacturers all listened to your complaints, is there any laptop left that would let me connect an external screen to the iGPU?
Nothing comes straight to mind as that’s uncommon, best bet is to check the “ports” timestamp in my review videos on YouTube as I mention where everything connects there. Unfortunately I do not document this in a central spot so cannot just look it up.
