Help!! Mac mini late 2012 trackpad delay on 4k tv

[kang8609]

My current Mac mini is the late 2012 edition with 8gb ram and 512GB SSD
My current Tv is the sony X900H 4k TV
My trackpad is a logitech keyboard+trackpad 2 in 1

I tried to use the HDMI port and there is a huge trackpad delay, the graphic is smooth, its just the mouse moves 0.5 seconds behind my finger's movement.

I've tried to switch to different resolutions and refresh rates but the problem still persists!

can anyone point me to the right direction?

Try switching the TV to PC mode or Gaming mode to see if the delay is reduced.

Also, check if Bluetooth and WiFi are on at the same time.

I have seen this issue and had to turn one of the wireless services off.

Thanks, but I tried the different modes and didn't help. I also tried another HDMI cable and port but still no help

I also tried to pair 1080p with 30hz, 1080i with 30hz and not working

I can't do that because both keyboard and mouse are using bluetooth and my router is on another floor

Can you change your wireless to use only 5Ghz?

2.4Ghz will interfere with your BT KB & M.
