pixel respons vs freesync(gsync)

[RasmusDC]

exchanged my 4K Dell IPS for an 144hz SR75 VA samsung, it quite like it, but have been playing a bit around..

 

after the update, it is gsync compatible, but it of course demands Freesync to be turned on in the screen, that blanks out my "pixel response" setting, which in the UFO test can make quite a difference, so the pixel response is way slower...

 

what would you choose, G-sync og better response time on pixels... it is QUITE a difference of ghosting in UFO test, and it does not seem to have forward ghosting in the highest response setting, the FASTEST...

Personally I'd choose to have better response times. I rarely noticed tearing in games but I did notice ghosting a lot. I exchanged my 144Hz VA monitor for a 144Hz IPS monitor with G-sync and I really notice the reduction in ghosting, the sync not so much. It's weird though that it's locked, those features shouldn't necessarily depend on each other afaik...

Yeah guess gsync is important if sub 60fps is normal... and not seing fps under 100 in any games... love the. VA like having black levels again, one thing missing from IPS

Odd, rtings didnt mention this issue in their review, which was updated as of the new firmware.

 

They do mention that 'faster' is better than 'fastest' as u d get some monitor overshoot. However if u dont notice it then its all good.

 

I would contact Samsung , ask whether what ur experiencing is normal of not.

 

It is unfortunate that sometimes standard Pixel response and/or Pixel response with overdrive settings, are tied to Panel frequency.  This can result in pixel response changing depending on the frequency the monitor is at during VRR usage.

Perhaps the pixel response when using overdrive is tied to the frequency in the SR75 and Samsung had to disable overdrive to stop pixel response form becoming unreasonably slow at lower frequencies with overdrive enabled.

 

Personally i would disable VRR, set the overdrive to what ever looks best, and then use standard Vsync or FastSync.

Normally perceptive to overshoot, the panel might differ... annoys me when companies grey out settings... it is a okay display, i am willing to sacrifice the ips gl850 pixel update speed for the black levels of this panel. Which are decent

So, on a lot of freesync monitors, it seems they tune the overdrive for around 90hz, and let that cover the range of 48-144hz. So you want to actually make sure you stay in the 70-110 fps range ideally if you are going to use it. On the other hand, 144hz with the more aggressive overdrive actually looks a lot smoother. So for desktop use, 144hz is better. For older games, imo, you can just use 144hz with vsync, even though there is an input lag penalty (20ms), it is substantially less than the input lag you get with 60hz vsync (50ms).

Used to disregard vsync istead just use the powersqve function and limit fps to 75 on my old screen worked perfectly the vsync lag seemed very high in some titles

The input lag is proportional to the frame times. At 144 fps, the frame times are small enough to make vsync usable imo. At 240 fps, it is completely negligible.

you might be right, this is my first.. "higher" refresh rate monitor, well had a 75hz, and ran higher hz in the CRT days.. (ohh the good old days)..
