4k@60hz output for hd 4600 on a mobile processor

[ETand]

I will add this link up front, as the page clearly says 3840x2160@60hz is supported:

http://www.intel.com/support/graphics/sb/CS-033714.htm http://www.intel.com/support/graphics/sb/CS-033714.htm

The problem is that I just picked up an Asus pb287q 4k single tile monitor(Havent received it yet). But then I get contradictory statements , notebook retailer saying it will not be possible, others saying it in fact is working...

So which is it ?

My laptop is a Clevo p157sm/Sager np8250 with a hm87 chipset. Windows 8.1 and the processor is a i7 4800mq.

I also got a hold of the "Mobile 4th Generation Intel Core Processor Family" - datasheets , and I'm quoting :

"The HDMI* interface supports HDMI with 3D, 4K, Deep Color, and x.v.Color. TheDisplayPort* interface supports the VESA DisplayPort* Standard Version 1,Revision 2.

Each digital port is capable of driving resolutions up to 3840x2160 at 60 Hzthrough DisplayPort* and 4096x2304 at 24 Hz/2560x1600 at 60 Hz using HDMI*"

"The processor is designed in accordance with the VESA DisplayPort* Standard Version1.2a. The processor supports VESA DisplayPort* PHY Compliance Test Specification1.2a and VESA DisplayPort* Link Layer Compliance Test Specification 1.2a."

There is no readily available information from resellers on this as I am aware of....... The only thing I was told in that respect is that there is no wiring/configuration in the clevo/sager that disrupts the output of the IGP, so that the rules for output that INTEL put in their support information will hold.

So ..... Is it possible to get an answer from Intel ?

Hi Jessup,

I understand you want to set up a 4k resolution at 60Hz so let me help you with this.

It is important to say that the processor you have (i7-4800MQ) is in fact HD 4600 and it should support 4k resolutions without a problem but you need to make sure you have the correct configuration to do so.

What I mean to say is that, as the Datasheet mentions, it is necessary to use a 2.1 DP cable or 1.4A HDMI cable (high Quality) with the correct Hz to make it work.

It is also important to say that this can be limited by the Computer Manufactures. This is because we provide the hardware to the Computer Manufacture and they will design and create their own systems including their limitations. This means that they can limit their own computers to resolutions or special features.

Now, there is always a way to force the resolution on a computer by using the Custommodeapp.exe in the computer (part of the Graphics Driver) or the latest software already has this included on the Intel® Graphics and Control Panel but you will need to play with the settings.

Here you can get more information about this:

Thank you Kevin for that swift response. I truly appreciate it 🙂

@ Jessup, Both HDMI inputs on the ASUS PB287Q will support 3840x2160 resolution up to a refresh rate of 30 Hz. If you want full 60 Hz operation, you have to use the DisplayPort input and enable version 1.2 in the OSD.

ThanksRobert

Thanx, Robert!

I have both displayport + mini displayport outputs, so definitely I'm using that 🙂 I do remember a lot of people mentioning the osd setting, so I will remember !
