Question Display resolution and CPU resolution match requirements & overclocking

[vimitgandhi]

Hi, I have a display panel with 3840 x 2560 @60Hz resolutions. Note that this verticle resolution is higher than the traditional 4K i.e., 3840 x 2160. Most CPU chips have either 4K@60Hz or 4K@120 Hz or higher resolutions. Given this situation, should I be opting in for bandwidth CPUs i.e., 4K@120 Hz? If

Bandwidth required for display panel = 3840 x 2560 x 60 = 590M
Bandwidth of 4K@60 = 3840 x 2160 x 60 = 498M.... lower than the required bandwidth
Bandwidth of True 4K@60 = 4096 x 2160 x 60 = 531....lower than the required bandwidth
Bandwidth of 4K@120 = 995M.....higher than the required bandwidth

Given the bandwidth of 4K@120 is higher than the required one, do we need to do any overclocking for the CPU to meet display resolutions of 3840 x 2560 @60Hz?

P.S. I am not an expert on display technology and finding the right chip for displays

Thanks

Supported resolutions do not depend on CPU overclocking.
They depend on graphics subsystem (graphics card and available video outputs i.e versions of HDMI and Display Port).

We have HDMI2.1 and DP1.4. Even with this, my question is more around whether CPU with 3840x2160@120 Hz can light up/support display with 3840x2560@60 Hz. What do we need to update and check in CPU’s parameters whether we can make these conversion or update the resolution?

what is the exact monitor and CPU?

Exact monitor or CPU does not exist together 😊 I am using the panel for digital signage application. Panel screen is same as the 28” monitor by BenQ model number RD28OU and for CPU I am considering MediaTek’s SoC MT9681 or MT9618/MT9689
