She has arrived, but one thing?

[Zeebedy]

Hey guys,

received my Mac Pro today and man its gorgeous. The issue I'm having though, is in 1440p it won't let me change the refresh rate (my monitor supports up to 240Hz), but when I downscale to 1080p I can change it.

Now, is this the Mac Pro or the cable I'm using to test out. Surely the cable? unless MP doesn't support it.

FWIW I have the MP model with the dual D500 GPUs.



Cheers guys!

Are you using the HDMI port or one of the mini-DP ports? What cable are you using?

 

[visibleman]

IIRC it was DisplayPort 1.2 on the 'trashcan' which means you will be limited to 144Hz @ 1440p due to bandwidth.
HDMI was 1.4, so 75Hz @ 1440p (i think).

Edit - I'm going off rusty memory as it's been a long time since i've touched a 'trashcan', so this could entirely be wrong

yeah HDMI to HDMI. Its a budget cable from the rainforest, so im assuming it might be that.

That would be fine for me, 144Hz. For what this will be used for. But defiantly struggling at 60Hz here atm!

ah yeah, you definitely won't be able to do 1440p @ 120hz+ over the HDMI 1.4 port, the mini-DP should work though (not 240, but 144 should be OK).

What monitor are you using? As you need to be using DisplayPort.

 

[Armageus]

Fairly sure HDMI1.4 won't do more than 75hz @ 1440p

HDMI - Wikipedia

en.wikipedia.org

Displayport (should be version 1.2 as part of Thunderbolt 2 spec) should do 165hz @ 1440p as per HBR2 column

so even a good quality cable won't do 144Hz at 1440p?

Its a Samsung one, will check the model in a bit.

So what cable do I need to get this to work at 144Hz?

 

[PaulM]

Not via HDMI. HDMI 1.4 doesn't support 144Hz at 1440p, doesn't have the bandwidth.

can you point me to the rainforest to see what cable I need?

that's unfortunate.

 

[Zeebedy]

im currently looking at DP to Mini DP?

is that correct?

 

[visibleman]

Grab the model number and post it, as someone can then see what options you have

No because OcUK sell display cables (although the range is admittedly pretty poor!)

Yes

Something like this, but ideally look for one labelled as DP 1.4, 4k@144hz or similar

My basket at OcUK:

• 1 x OcUK Value Mini DisplayPort to DisplayPort Cable 2m (SKU: CB-089-OK) = £4.69

Total: £8.69 (includes delivery: £3.99)​

thank you, and that would just plug into and 6 of the mini DP on the MP?

As far as I know (I'm not a Mac guy!)

Thunderbolt version 1 and 2 (as used by your Mac Pro) just use Mini displayport connectors - with thunderbolt 3 onwards they changed to USB-C connectors

Can't believe you actually did this.

You need your bump feeling

Hey guys, I’m just reading around, how would this stack up against a M1 mini in 2021? Just weighing up my options in case of some of the horror stories from the early M1 chips continue to persist for a fair period of time.. can pick up in similar price bracket to my 16gb mini on order, plus I...

That is my excuse

Seriously though. Apologies.
