Surface Pro 3 HD 4400 I5 processor not producing 3840x2160@60Hz with displayport

This problem is similar to the one reported for the HD 5000 and the I7 in that it can only display mailto:2560x1440@60Hz 2560x1440@60Hz using the displayport and the default MS drivers or the Sasmsung drivers. It appears to be specific to the Samsung UHD monitor U28D590D. The monitor and cable produced mailto:3840x2160@60Hz 3840x2160@60Hz using an AMD R9 280 video card on a Windows 7 system. The cable manufacturer tested some of their cables using a Surface Pro 3 and Panasonic monitor. They were successful in producing mailto:3840x2160@60Hz 3840x2160@60Hz. The Intel Info page reports that the monitor is capable of mailto:3840x2160@60Hz 3840x2160@60Hz. When trying to add that resolution to the Intel HD graphics control panel it reports that it does not have enough bandwidth. A displayport resolution of mailto:3840x2160@30Hz 3840x2160@30Hz was successfully added. A replacement Surface Pro 3 was dispatched by Microsoft and it suffers the same problem as the original. At least using the Intel drivers can produce the right resolution! Any thought on why the bandwidth issue is popping up?

.

As an update, the Intel Info page reports that the chipset (assumption) is capable of supporting up to 60Hz. The maximum refresh rate supported that we achieved was mailto:3840x2160@50Hz 3840x2160@50Hz using the CVT-RB timing standard . Power settings when plugged in set to Maximum performance. A rate of 55Hz was attempted but it produced a maximum bandwidth error!

If someone can find the detailed specifications of the HD controller we may be able to get to the bottom of this. At 24 bits/pixel the clock rate has to be greater, because of overhead, than 3840x2160x60x24/4 = 3Gbits/sec per each of the 4 displayport channels.

Hello Vescovo

Intel supplies generic versions of its graphics drivers for general purposes. But, the computer manufacturer can change the features, incorporate customizations, or make other changes to the graphics driver software or software packaging. To avoid any potential installation incompatibilities, Intel recommends that you first check with your computer manufacturer and use the driver software they provide.

You can try the following driver:

You would need to install it manually:

Thank you for the suggestion. Unfortunately, the download of the 64 driver is producing a 404 error.

Re: Surface Pro 3 HD 4400 I5 processor not producing 3840x2160@60Hz with displayport

Hello Hans,

Thank you for your effort. Unfortunately the refresh rate is till limited to 50Hz. I even tried 51Hz and it fails with not enough bandwidth.

Re: Surface Pro 3 HD 4400 I5 processor not producing 3840x2160@60Hz with displayport

Hello Hans,

You are probably pulling your hair out with Windows 10 issues at the moment ..... Anyway, windows 10 was installed on the service Pro 3. The default MS drivers produced the same problem in that the Max resolution supported is 2560x1440@60Hz. Installing the Intel windows 10 drivers 15.40.4.64.4256 (Latest) manually produced the same results as windows 8.1. That is the maximum resolution is 3840x2160@50Hz. Are you able to get a hold of the HD4400 spec and determine the maximum clock rate per channel that it supports?

If the hardware supports 3840x2160@60Hz then I can wait for the drivers to be updated but if it does not then I need to have a discussion with MS.

Re: Surface Pro 3 HD 4400 I5 processor not producing 3840x2160@60Hz with displayport

Do you have the exact processor model for this system, to find out what will be the Max resolution supported?

Also, you can see the maximum resolution supported at:

I don't know if you already install the latest driver but for Windows 10 you can download it here:

Re: Surface Pro 3 HD 4400 I5 processor not producing 3840x2160@60Hz with displayport

Hello Ivan,

Processor Model i5-4300U @ 1.9GHz

HD Graphics 4400.

The current driver will not even manually install!

To install the mentioned driver on a Windows 10 upgraded Surface Pro 3 and create 2 custom resolutions at 3840x2160@50Hz 3840x2160@30Hz the following procedure was followed.

1) Download the 64bit version of the Zip file.

2) Extract the Zip file.

3) Select Device Manager using the windows key-X and then expand the Display adapter.

4) Select properties of Intel Display adapter and uninstall driver. This will put Display in VGA mode.

5) In the Graphics directory of the extracted driver right click and install the igdh64.inf.

6) In Device Manager scan for new hardware. This will restore the standard MS driver.

7) Select Properties of Intel Adapter, select Driver tab, select Update Driver, select Browse My Computer, select Let me Pick, select the newest driver(10.18.15.4279 [2015-08-24])

😎 Driver software should install Intel HD Graphics Control Panel.

9) Right Click display and select Graphics Properties.

10) Select Display, select custom Resolutions, say Yes, Select your UHD display in Select Display.

11) Set width and height to 3840x2160, refresh 30Hz, Timing standard CVT-RB and then Click Add.

12) Set width and height to 3840x2160, refresh 50Hz, Timing standard CVT-RB and then Click Add.

13) Close the window and restart Windows 10.

14) After restart you should be able to select the higher resolution modes.

Re: Surface Pro 3 HD 4400 I5 processor not producing 3840x2160@60Hz with displayport

Hello Vescovo,

We appreciate you have replied with this information; after checking specifications of this processor I can see that it supports the following resolution:

You can see more detailed information here:

http://ark.intel.com/products/76308/Intel-Core-i5-4300U-Processor-3M-Cache-up-to-2_90-GHz http://ark.intel.com/products/76308/Intel-Core-i5-4300U-Processor-3M-Cache-up-to-2_90-GHz

Also, I strongly recommend installing the latest driver from your system manufacturer website as they have the proper drivers for your system.

Re: Surface Pro 3 HD 4400 I5 processor not producing 3840x2160@60Hz with displayport

Hello Ivan,

It looks like your specification and the Microsoft specifications are different. In MS published spec it indicated it should support 3840x2160@60Hz. From reading the rest of the Processor specifications you sent it appears that may not be possible. Why do you recommend that I not use your driver? I had your driver installed prior to the upgrade to Windows10. It was replaced with the windows driver yet the max resolutions of 3840x2160@30Hz and @60Hz continued to work properly until I, in error, clicked the 59Hz on the properties window. This caused the 3840x2160 settings to be deleted and left me with a max of 2560x1440 resolution. I purchased a 4k display because the extra pixels are required. It appears a little strange that the display port capability is less than the HDMI. Is there a reason for this? I am running using the DP port without a problem at 50Hz for single screen mode and at 30Hz for extended display mode. The 30Hz is well within the rate specified by your 3200x2000@60Hz. The 50Hz is above the rate of 384Mhz without overhead. Does Extended Display mode treat the combined graphic display memory as (2160+3840)x2160@30Hz?

As you suggested, I have rolled back the driver by following the same procedure as for the installation except when selecting the MS preferred driver from the list. The maximum resolutions available are still 3840x2160@50Hz and 3840x2160@30Hz.

Kind regards

Re: Surface Pro 3 HD 4400 I5 processor not producing 3840x2160@60Hz with displayport

I recommend using the driver from your system manufacturer because that is the proper one for your system and the one we have is a generic driver, if you install our driver and it works fine then it will be fine for you.

Max Resolution with display port is the maximum resolution supported by the processor via the DP interface (24bits per pixel & 60Hz). System or device display resolution is dependent on multiple system design factors; actual resolution may be lower on your system.

You can see more detailed information about resolutions at:
