Trying to hook up a Samsung U28D590 4K monitor (3840 x 2160 pixels) to a system with an integrated Intel 4000 graphics chipset (running Windows 7 SP1).
According to the Intel specs, the Intel 4000 chipset should be able to handle at least 2560 x 1600 resolution.
Windows is only allowing up to 1920 x 1080 pixels of resolution.
What has been tried:
- Installed the drivers that came with the monitor and rebooted, but no difference.
- Set the refresh rate of the monitor down to 30Hz, but no difference.
- Bought HDMI cables that specifically list support for 4K devices, but no difference.
Would like to get it to run at 2560 x 1600 (or higher).
How?
Update: Well, it looks like I've exhausted all possibilities, including trying 4K HDMI cables. Taking a closer look at the specs for the Intel 4000 (which Intel has made amazingly difficult to find), it looks like it may only support resolutions above 1920×1080 when using DVI, which I don't have. So the Samsung 4K display gets returned or sold.
Best Answer
I'm running 2560×1600 on Intel HD 4000 without any tweaks:
There are some pitfalls like attempts to use HDMI display connection at standard HDMI 1.2 which cannot handle that resolution (you need HDMI 1.3, and above 2560×1600 you will need HDMI 1.4); or using cable with insufficient parameters for given link speed etc.
Add display type and HDMI level of your cables to the question to get more helpful answers.
