As an ancient lightboost user this review got me pretty excited as the display sounded perfect minus the TN screen. Until I read the comments that is.
It's worth noting that ULMB (lightboost) and Gsync don't work together, which is also true for Motion Blur Reduction and Freesync. I don't know if they ever will, since strobbing + adaptive sync might either be difficult to pull off or look really weird.
In the end, Blur Reduction is amazing if you can maintain a fixed maximum framerate (like 85, 100, 120, 144) while gsync and freesync are great if the framerate is not stable.
Blur reduction + high/max fps = blur free (sample and hold) CRT like experience
Blur reduction + random/low fps = terible stutter (CRT like experience)
Adaptive sync + high/max fps = does nothing
Adaptive sync + random/low fps = no stutter or tearing
Blur reduction is great for powerful PCs and non demanding games. It's amazing to see all the detail in the picture while stuff is happening at high speed on the screen.
Adaptive sync is great for weak PCs, poorly optimized games or high resolutions. You'll be stutter free, but sadly not blur free.
So the current issues of this monitor are that:
- freesync disables AMA (which is an overdrive feature to improve pixel response time at the cost of overshot artefacts) which means that in freesync mode the monitor will have more pixel transition blur (from 1ms to 8.5ms gtg, don't quote me on this). I don't know how much full black to white pixel transition changes from the stated 7ms (at 1ms gtg).
- Motion Blur Reduction only works properly at 120 and 144hz, with lower refresh rates being either desynced (causing stutter) or double strobbed (causing a double image in moving objects)
What does work:
- freesync without AMA
- Motion Blur Reduction at 120 and 144hz
Is it worth buying before the issues get fixed? Probably not.
I would more likely get an Acer Predator XB270HU, which is ISP, has Gsync and ULMB up to 100hz.
Tech like AMA will probably dissappear once we move on to OLED (which is free of pixel transition blur at 0ms, but not sample and hold blur for which we'll still need Motion Blur Reduction).
