Intel(R) HD Graphics 4000 maximum refresh rate at 1080p

PMari6 — Tue, 10 Sep 2019 22:09:04 GMT

I have Intel(R) HD Graphics 4000 iGpu in a laptop DELL with CPU Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz. I have an external display connected over HDMI (my only video output port) that can do FULL HD at 144 Hetz (1920x1080@144). When I try and set a custom resolution in the intel display settings, I can set Full HD at 95 Hetz. Anything above 95 hertz and an error message appears saying "The maximum bandwidth was exceeded.". The bandwidth of what? HDMI port is version 1.4 on both monitor and laptop. It can handle 1920x1080@144 hertz according to Wikipedia HDMI version specification. The HDMI cable I have is high speed one. The monitor can do more than 95 Hertz over HDMI (tested on another PC). What is holding back?

Thank you for the information provided,

After a deep research I found out that the 2nd and 3rd Generation Intel® Core™ Processors maximum resolution over HDMI 1.4 is: 1920x1200 at 60 Hz, you can confirm this information by accessing the following link.
