From another review:
cons: -Response times not perfect and are limiting at upper end of refresh rate range
-Blur Reduction mode shows noticeable strobe cross-talk
"As the refresh rate drops below 120Hz the overshoot starts to become far more apparent, and dark and pale halos become more noticeable. Even more so because of the reduced frame rate in fact. Thankfully, unlike the V1 firmware which the screen came with, the response times were at least adequate to support the high refresh rate and frame rate on the most part. By the time you reach the maximum 144Hz too many transitions are slower than the required 6.94ms and you do get some additional smearing introduced in practice. Up to around 120Hz is mostly fine though and probably the upper limit of refresh rate you'd want to push this panel to we think. Again, if you're using this 'fast' mode you don't want refresh rate to be too low either as the overshoot starts to become a problem. We'd say stick to the 'fast' mode for 100 - 144Hz range but preferably try and cap your refresh rate to around 120Hz maximum to avoid additional smearing at the very top end."
They are saying the transitions at the top end of the refresh are too slow to handle it.
Did you find anything similar?
Interesting.
People blast NVidia for having dedicated hardware (GSYNC Module) but avoiding issues like overdrive color quality problems is one of the main reasons NVidia did that.
For those who don't understand what's going on, the response time (time for pixels to change color) is too slow normally at the shorter frame times so they drive it with more VOLTAGE than normally to try to hit the color target (then back down the voltage to try to stay at the correct value).
When the FRAME TIME is constantly varying it's difficult to do this properly. You essentially need a look-up TABLE of values of "Frame Time range vs Voltage" and good control over the voltage delivery system.
That's probably difficult to do with Freesync since the point is to do this without adding new hardware. NVidia on the other hand probably has a look-up table but I'm guessing. Probably GSYNC 2 will add in a lot of things too to stabilize color, blur etc but despite "FREESYNC 2" sounding neat they are still limited without making an actual module.
*Now a company can of course create their OWN hardware that ties into the internal scaler to sort out these issues but it's a hassle. A lot of monitors can't even handle LFC (Low Framerate Compensation) so Freesync is a bit of a mess in terms of finding the right monitor that does ASYNCHRONOUS mode well.
I doubt most REVIEWERS know all the things to look for. In fact, I'm not even certain how big a DEAL the color quality issue is for this monitor as some people seem to notice things like this more than others.
