Hello,

I have a generic 144 hz monitor and a generic DP cable. With progressive res. I feel my mouse a bit floaty. Today I created an interlaced res. with CRU and surprisingly my mouse felt more responsive at the cost of image quality.

Does interlaced resolution really decrease input lag?

Can the problem be my DP cable? If a buy an expensive cable do you think it will improve responsiveness?

Last time I heard HDMI is potentially lower input lag than Display port, but next to nothing

Shorter, thicker/shielded cables are generally considered best

More concern is the display profiles and display transceivers inside the monitor -- for example latency settings and picture settings are different for HDMI vs DP. So that can be the bigger lag difference.

An example is the XL2411P might have the "Instant Mode" setting enabled on one port but not the other port. Even mere differences in overdrive and HDR/color processing settings can create a bigger lag differential -- processing overheads are often bigger than the HDMI-vs-DP difference. So check the settings of the display profile assigned to the specific video input.

While there's a sub-millisecond lag difference between HDMI and DP, sometimes it's easy to target the wrong tree in the lag forest...
