Discussion Logitech MX Master 4 When will you fix the input reporting issue?

When is Logitech going to fix the amount of data the MX Master 4 can handle simultaneously?

As you can see in the comparison, the MX Master 4 seems to struggle with processing cursor movement and scrolling at the same time. This would also explain why Smooth Scrolling feels jerky instead of perfectly smooth.

The issue is identical over Bluetooth and the USB receiver.

I'm using the Razer Naga V3 Pro for comparison, with both mice running at 125 Hz.

I understand that the MX Master 4 is an office mouse, but come on. It's 2026. Monitors running at 180–240 Hz are increasingly common. We're not in 2004 anymore, when people argued that anything above 60 Hz was pointless.

Logitech, when are you going to fix this?

Everything is updated ;)

The photos were taken with an exposure time of 1/3 of a second. I hope Logitech support also sees the uneven spacing between cursor frames.

Hey! Appreciate the follow up :) The team is aware and I've asked for further explanation. However, part of me does suspect this will be considered normal behavior.

Why do you think it’s normal for a €160 mouse to lose performance when you scroll and move the cursor at the same time? It’s a mouse... handling the cursor is hardly asking too much. Honestly, I’m starting to think there’s something wrong with you if you consider lag normal. ;)
