Oh Im sorry, I already shipped back the HP Omen, I couldn't accept the fact that he was missing the option of saving profiles and the motion blur wasn't even any better, I managed to only film a movie with a acer vs omen compare of motion blur (ufo test).
HP Omen has slighty visible overshoot at his best overdrive, so in this case + extra BFI (motion blur reduction) the acer is better. Seems if someone want to use the acer its very good choice, except the black color uniformity which you need to deal with. I realised to deal with it you can slighty increase the black boost, I used it 0 at the desktop and 8 in games, but the 2 mode for movies seems better than 0.
Tommorow I will get the MSI, finally, can't wait. Its hard to me to accept 27 inch of asus after few days using it vs Acer.
So if MAG will not be nice for me then I will stick probably with the Acer over Asus VG279QM (my VG259QM was deffected imo, cuz at 80 OD there was more visible overshoot compare to 27 inch version).
==========
also I got message from Ashun (the guy who review the VG279QM (with the froggies on youtube and his website) and he said that if it comes to input lag, the processing Lag is most important, so even Asus has 0.30ms Processing Lag, when Acer Nitro for example has it at 2.0ms, thats a big difference imo. The msi has similar input lag in this case, 0,29ms processing lag, which is nice to know,
he said, we should not look at 2,38ms or 1,97ms. Because for example this is how Hardware Unboxed got the 2,38ms on MSI . At 240hz one frame leasts 4,16ms. The average lag over the frame is just half of that, so he takes 4,16/2 = 2.083. Take that 2.083 and add it to the processing lag, 2.083 + 0.29 = 2.373
