DELL S2716DG ghosting issue

[RARg]

When I run this test: https://www.testufo.com/#test=framerates-text&pps=1440
on DELL S2716DG I can see white letters below the actual text.

It's pretty annoying. I tried setting Response time to normal, but it only makes it a little bit less visible. The same goes with changing ULMB and refresh rate.

I want to keep it 144Hz, but the ghosting is clearly visible in the browser and in games.

Any ideas what settings I can change to get rid of ghosting? Or maybe I should buy different monitor.

I find I get more ghosting/motion blur with f.lux turned on (reduces blue light). Maybe you have something like that open?

I have the same monitor and there is no solution as far as I can tell.

@Froody129 I think no

If it's a common issue I think I should buy different one.

Thanks for help.
