This is strange. What mac are you trying to connect and are you using any adapters?
tried 5 different docks, macbook pro touchbar 4 thunderbolts(2019 i think)
I feel your pain bruh.
It might be the HDMI cake that limits the refresh rate, or if the Mac you are using doesn’t have a hdmi port it might be the adapter that is causing the limit. The specs for the monitor say it should go up to 60hz at 4K
same exact setup pushes 4k 60hz to any Dell in the office. at this point i tried 5 different docks

my laptop is in RMA so im stuck with this for a bit more (and i tried using linux on it but it sucks)
You sound like a super happy person, I’m sure people love spending time with you
Dafuq? XD
Sure buddy,remember to take your medicine
Lol what a weirdo
Have a look at BetterDisplay. It should unlock all functions of your display past Apple’s restrictions on 4K monitors.
thanks but it doesnt let me select the refresh rate which is the problem here.
also … paid software to set display resolution. oooof

yeahh, thats not acceptable for me.
SwitchResX should be able to help you. I use this with my Mac VM, the dummy plug I was using wasn’t showing me most of the resolutions I know it supports and this fixed it
thank you! sadly when i select the correct resolution and framerate from this program it applies correctly but the image quality is much worse than 30hz, very blurry and basically unusable… bummer
Strange. Have you tried switching out the HDMI or Displayport cable you have hooked up to the monitor currently?
yes and those work fine with every other laptop here so its not that
Mine was like that with HDMI cable until I have my hands on the
usb-c to mini-display cablei only have type c ports here so everything goes trough a dock(and i tried 5 different ones so its not that)
if you have a usb-c to display port, give that a try without a dock usb-c hub -> usb-c display port only work on high end hubs (i have an alogic right in front of me now that works)
i tried 5 docks that work fine on any other laptop
If you’re trying to troubleshoot this, he’s saying to try it with just the cable so that you can identify that it’s the doc causing the issue and not your computer/os/monitor/cables. Remove variables and continue.
i tried 5 different docks, its not the dock…
all those variables work fine with any other laptopt, the macbook is the variable here.
They are telling you not to use ANY dock. Connect the cable to the monitor.
My Macbook drives a 144hz 4K display, so your issue is not your Mac unless you have an Intel based Mac.
Likely it is either the cable or user error.
This MacBook has 4 tpye c ports and that’s it. So you need some kind of adapter,no way around it. I tried and the results are the same.
You come here asking for help and dismiss people trying to help lol
Where did I ask for help?
Where did I ask for help???
Have you tried a different OS on the laptop?
Have you looked for updated drivers and firmware for the dock?
For the brief time while I had Linux on the laptop it worked fine 4k 60p.
No I didn’t since they work fine with other laptops
I think I hit this issue before. If you’re using hdmi try using DisplayPort.
Or VGA
…why
yeah apple’s dp support is much better then hdmi
After reading these comments…

Something is up with the Dock-Mac. Could be firmware. I have a Lenovo Thunderbolt 3 dock that refused to do 1440p/60hz in Windows, but would on my Mac only to drop out every few minutes. Firmware update solved both sets of issues.
Had another USB C dock that used DisplayLink, which wouldn’t do above 30hz on my Mac until I downloaded the DisplayLink driver.
What’s the dock you are using in the office?
tried 5different docks, dell,lenovo,apple adapter and 2 no brand ones. same result. all these docks do 4k 60 on any other pc
For sure, I edited but that can take a minute, whats the dock you are using? I’ve been through a bunch of this stuff. If it’s a DisplayLink dock, you will get no love on MacOS without the driver, no mater what cables you use. If it’s one of the many USB based docks common to office fit outs, that might be your trouble.
i tried 5 , dell,lenovo,apple adaptor and 2 no brand ones
Right, so you tried 5 different docking stations? As I said friend, Lenovo and Dell both make DisplayLink docks that are super common for office use.
The Samsung U28E590 from your screenshot does not support 4k60 on both HDMI ports, and only does 30hz on Port 2 regardless of resolution. So if the Dock is in port 1, and you go USB-C > HDMI on port 2, you are not going to get 4k60, because the monitor can’t do it on anything but port 1.
If you are using the Apple USB-C > HDMI, you should know it is oldAF any maxes out at 4k30hz (HDMI 1.4). The updated adapter came out in late 2019 and added 4k60 and HDR support (HDMI 2.0).
In the more likely event that you have random office supplied cables, USB-C to HDMI, a SHOCKING number of them are cheap trash and will not do 4k60, but should do 1080p60… unless plugged into HDMI 2 on the monitor listed.
Lenovo and Dell both make DisplayLink dock
yes and the other ones are not displaylink
its connected in hdmi port 1.
If you are using the Apple USB-C > HDMI, you should know it is oldAF any maxes out at 4k30hz
yes, but it should be able to do 1080p 60.
as you say, they should do at least 1080p 60, they dont. because its not the cable or the dock.
That is indeed MildlyInfuriating - sucks dude!
My work issued Lenovo laptop only does 1440p/30 4k/30 with it’s built in HDMI and, for reasons that make sense only to Lenovo, also is 30hz capped when connected to their USB-C and Thunderbolt dock for who knows why. Drives me crazy.
you would think humanity has solved the Hdmi issue at this point…
Everybody Hertz
My coworker had this issue recently, and he had to screw around with different cables, docks, and profile settings on the monitor itself for half an hour before the better refresh rates showed up
The doctor has diagnosed your problem. You should lower the screen frequency as you complained that it Hertz a lot.
Because of your title, I decided to see if I could guide ChatGPT into calculating the theoretical refresh rate at which the monitor would start to cook its user. It really fought me and wouldn’t even attempt the calculation, but it did give me this suggestion for my post that’s so bad it’s almost good…
For example, you could playfully suggest a refresh rate of “1,000,000 frames per second, capable of grilling a hotdog if you accidentally stand too close!” Remember to keep the humorous tone and make it clear that it’s a fictional scenario for entertainment purposes.
ChatGPT can’t calculate. It can just ‘complete’ (maybe you could call it ‘generate’) text.
I’m not sure that’s a fair categorization. It can code complete and perform mathematical calculations, even if the way it is achieving them is unconventional. For example, I asked it to answer a novel calculus question and it handled that:
It doesn’t seem like such a leap then to calculate the “cooking refresh rate”, provided it has all the variables. The problem is, I don’t know all the variables necessary, so I can neither provide them nor tell it where/how to derive them.
ChatGPT can’t do math. It would make up a coherent formula that looks right but it’s literally not designed to know how to calculate things. Ask Wolfram Alpha instead.
Why would refresh rate cook anything? If the pixel was on continuously, it doesn’t cook anything, then why would modulation matter? It’s not like you’re increasing intensity.
My line of thinking was that a higher refresh rate uses more power, so the monitor gives off more heat. If you could continue to increase that unbounded, without stopping for silly things like safety regulations or power draw, that you could eventually get to a refresh rate which would cause the monitor to boil the user alive - a la what-if.xkcd.com
Theoretically. I mean, by the current laws of physics an analog display is at the infinite limit of refresh rate. In practice, though, existing consumer digital circuits take energy to refresh.
I don’t need my AI to be such a nanny. Give me the dangerous information ChatGPT!
Is it an Intel GPU? I’ve a Dell with an Intel hd620 that won’t do 4k60 over HDMI on Linux/Win/Mac(osx86).
Needs DisplayPort to reach 4K60hz.
its intel yeah, well i would understand maybe 4k 60 but here i cant even do 1080p 60 XD
Oh yeah I didn’t even register that! Yea, that’s a pile of shite all right
Macs can be weird about this sometimes. Did you try a 4K/60 usbc to hdmi adapter with the appropriate HDMI cable? I typically use Anker adapters but anything with the proper rating should work.
tried 5 docks at this point from lenovo/hp to no brand, all work fine with all other laptops
