Hello. Like a week ago i bought monitor Acer CB281HK it supports 4k at 60Hz via HDMI.
The problem is that when I connect my laptop to monitor by HDMI (2.0) cable it stands on 4K but on 30Hz max.
Laptop is Lenovo ideapad Y700 ISK17
Steps I took before I wrote here:
- to be sure I got 2.0 HDMI cable i just bought it new thats says its 2.0 and its Premium HDMI Cable
- Checked is my monitor supports 4K 60Hz via HDMI
- Checked all monitor options
- Checked all Windows 10 options
- Checked is Intel HD530 supports 4k 60Hz via HDMI
- Checked monitor, Intel HD530 and Windows to have latest drivers
- Read tons of forums to figure out the problem
Is there any more step that I can take to get pleasure of viewing 4K in 60Hz?
According to the specs, the HDMI port in your laptop only supports HDMI 1.4a - which means that 4K @ 30Hz is the best you are going to do.
If you had a way to access one of the processor's DisplayPort 1.2 output streams, you could use an adapter to get 4K @ 60Hz, but I could not see any way to access any of these streams in your laptop.
The other option is to use a USB 3.0-based Graphics Adapter that supports 4K @ 60Hz. Here are some examples that claim this level of support:
Hope this helps,
