I have an MSI H81M-E33 motherboard with a Pentium G3220 CPU running Windows 10 64bit preview (build 10130) with display via HDMI to an UHD TV - LG 55UB950T. I want to see 3840x2160 at 24 Hz resolution, but I only manage 1920x1080 60 Hz. I want to know why I cannot, and what I need to change to get a 4K display (new CPU, or new graphics adapter, or what).
I have been trying to work out what the HD Graphics in the Haswell Pentium G3220 consists of. In another post, I saw the definitions of the other Haswell graphics devices.
There was a comment that the G3220 HD Graphics was a third generation graphics. But, when I look at the Specification of the Haswell processors (including Pentium), I could not see that. My reading was that the Haswell Pentium processors should support 3840x2160 at 24 Hz on HDMI.
The Wikipedia article on HD Graphics does and the Intel ARK website specs for the G3220 do not give any real details about generations
So, my question is, does the Pentium G3220 support 3840x2160 graphics at 24 Hz on HDMI ? If yes, any suggestions on what I should do to achieve it? If not, why is it not clearly spelled out in the documentation; and, what should I change? I bought the CPU and motherboard so I would be able to run a 4K display.
The Celeron and Pentium CPU's do not support 4K resolutions such as 3840x2160, only Core (i3,i5,i7) based CPU's support 4K resolutions.
