4k 60hz DisplayPort Cable for under R200?

There's a DP to DPmini cable for R170 with good ratings on Takealot but I think DP to DP is the most reliable, these cable can be finicky.

My PC is DP and the monitor can take DP or DPmini.

I've found a few, for 4k60Hz you need a Display Port cable that can do min 12.54 Gbit/s HBR2.
A mini Display Port is apparently identical(electrically) to a full sized Display Port other than the smaller jack.

I'll put them here in case anyone is looking in the future:

R107(This is probably also available from Esquire) https://www.geewiz.co.za/display-po...0-pin-male-20m-displayport-monitor-cable.html

R149 DpMini https://www.takealot.com/baobab-mini-display-port-male-to-male-cable-1-8m/PLID58570563

R189 https://www.loot.co.za/product/baobab-4k-display-port-male-to-male-cable/lytk-6338-g040

R170 Mini DisplayPort to DisplayPort Reviews all say it will do 4k60 https://www.takealot.com/ce-link-mini-displayport-to-displayport-cable-black/PLID49182952

R199 https://www.takealot.com/baobab-4k-display-port-male-to-male-cable/PLID55062926/description

Might as well ask here - Has any one tried running 4K60hz with Intel 4600 HD Graphics?
It's an i7-4790 SSD 20GB Ram
No gaming only watching video and some design work with Photoshop and LR.

From what I can find on Google it will work fine, the only caveat is it can do 4K 60 Hz over DisplayPort but will be limited to 4K 30 Hz over HDMI. But that may be due to how old the article was, seems last few gens of HDMI can now in fact run 4K60 fine, anything above 1.4 will be fine.
"If the HDMI port on your laptop is revision 1.4 then it is not capable of driving 3840x2160@60hz due to insufficient video bandwidth."

Bit more info to add:

All DP cable are the "same", except very old/funky reduced bitrate (RBR) ones. There is no such thing as a 4K cable or DP 2 cable. Specifically:
A standard DisplayPort cable, including the so-call DisplayPort 1.1 cables, will work for any DisplayPort configuration including the new capabilities enabled by DisplayPort 1.2, including 4K and multi-stream capabilities. All standard DisplayPort cables support RBR, HBR (High Bit Rate), and HBR2 (High Bit Rate 2), which can support 4K at 60Hz

Source - chairman of the org that sets standard. At least that's the intention.

...enter shyte manufacturers making inferior cables so bad that it doesn't work despite just being a piece of copper/alu.

So they introduce cable certifications - which are optional. That maps broadly to transmission modes...which are introduce during DP version changes made to the end devices - not cable - which in turn drives whether a setup can do 4K60fps

...manfacturers don't want to pay for expensive certification. Instead they slap a 4K on the marketing and call it a day. Unfortunately that confuses the kak out of people because that's all back to front as per above.

Takes a bit of doing but one can get actual certified cables....and they're not that much more expensive.

HDMI is in a similar position...HDMI 1.4 cables and 2 are the same thing in terms of wiring etc....just depends on how crappy the quality is.

So reading the above I shouldn't have any issues with a DP to DPmini cable as long as it's well made?

Having DPmini on one side will mean I can also flip the cable and use it with my laptop for 4k60.

I bought this when it was R140 on sale and it works fine for 4k60. It struggles a bit with 1440p165hzHDR though - flashing line or blank screen every now and then.


Others by the same brand would probably work as well.

Has anyone compared using a DPmini vs full sized DP?

I got a uGreen DP cable but I can't get 4K 60hz only 30hz, I can't even try select 60hz
Intel 4600 HD Graphics, i7-4790 SSD 20GB Ram
If I try add a custom res 3840x2160 60hz using the Intel app I get an error when tryng to save the res "The custom resolution exceeds the bandwidth capacity."

My CPU specs:
Max Resolution (HDMI) 4096x2304@24Hz
Max Resolution (DP) 3840x2160@60Hz

It's a Lenovo M93 desktop, would that have any impact?

Does the motherboard have DP 1.2?
I know my Dell Precision 5510 with a n i7 6820HQ straight up does not support 4K60 from the laptop's HDMI port. It works if you plug it into a docking station that supports HDMI 2.0.

Apparently 1.1 vs 1.2 is determined by the hardware not the physical port or cable, so my i7-4790CPU determines that because its an integrated GPU.
Spec sheet for the system also show that it will support 4k 60 via DP:
Intel HD Graphics 4400/4600 in processor, uses main memory, DirectX 11, one VGA, two DisplayPort, supports three independent displays, works along with discrete graphics to support five independent monitors; Max resolution: 3840x2160 (DP)@60Hz [HD 4x00]; 2560x1600 (DP)@60Hz [Intel HD]; 1920x1200 (VGA)@60Hz (Reduced Blanking)

Seems Multi Stream Transport (MST) being enabled on the Display was the issue, with MST set as primary or secondary the computer won't show anything but 30Hz but when disabled the computer immediately switches to 59hz and then I changed that to 60hz. I'm assuming there would be insufficient bandwidth to run 2 displays at 4k so that's why that was happening. What an epic waste of time to work that out :(

All good though, 4K on a 27" display is pretty epic!
