Why can you see a shadown behind the cursor when moving it on 60hz but not on 144hz?

[Guest]

If you've used a 60hz and 144hz monitor you will know that moving a mouse feels really strange when switching from 144hz to 60hz. But I have also noticed a little, almost unoticable shadow trail just behind the cursor on a 60hz monitor, any reasoning behind this?

I honestly cannot see any shadow on my 60hz monitor

simple, the mouse is  moving faster than the refresh rate so it doesn't get immediately refreshed.

No, maybe it's your LCD has bad refresh time

 

it's called ghosting.

If you're comparing two different monitors its because the 60hz monitor has a slower "response time" than the 144hz monitor. The pixels in the monitor take too long to switch colours as the mouse is moving away (casuing the pixels to have to switch from white to whatever background colour was under the mouse at the time). If this process takes too long it can result in shadows or blurs behind motion on screen.

As @Blebekblebek pointed out, this is called ghosting.

 

@Celios would you be able to provide links to the monitors in question?

The monitor is the APC G2470PQU.

 

When I set it to 144hz there's no shadow behind the mouse, just when I set it to 60hz.

The refresh is 60hz and I cannot see the shadows when I set it to 144hz. So I wouldn't call it "bad refresh rate". I don't think this is ghosting, but I'm not 100%.

I didn't say refresh rate

it's response time, which my phone is always correct it.

 

Response time and refresh rate are two different things

This is what you see

If you have ghosting with low refresh rate that means your computer producing more FPS and your screen can't keep up

and since you are using 144Hz it force your system to use 144Hz setup on 60Hz output.

 

I don't why it happens with your new monitor, as it should be automatically adjusting

Maybe reinstalling driver would help, maybe you've got defective unit.

No, Windows actually have a shadow effect you can enable and disable on Mouse settings if I'm not wrong, I personally like it and have it enable on my 80hz monitor, it has nothing to do with ghosting.

But that is disabled by default, right? I checked and it's not selected.

Frankly I'm clueless, on my desktop it was activated by default but on notebook it wasn't...

I've got 3 of these monitors and it does it on all 3, it's almost unoticeable though. 

 

It also serms taht that this is a common issue on this monitor:

Could I be looking at a GPU issue then? Is the GPU forcing 144hz on 60hz monitors? 

 

Or could this be the issue? (review of the monitor);

Ah, figured it out. Changed Overdrive to "Light" and it got rid of the shadows.
