Blur Busters Forums

Hey Blur Buster forum I recently purchased a Gigabyte M27q and I notice something very strange. According to Rtings, Tom's Hardware, etc. I should not be able to run Black Frame Insertion (Aim Stabilizer) and Freesync at the same time. However when I pointed my smart phone camera I am able to what seems to me a strobing effect. Could someone verify this or is the camera seeing things?

BFI PLUS FREESYNC https://youtube.com/watch?v=Re9soL_mfjI

BFI ONLY https://youtube.com/watch?v=toFSWFodl1A

FREESYNC ONLY https://youtube.com/watch?v=UgFWEKL_O6E

As you can see with Freesync only there is no strobing from freesync. With BFI locked at 170 hertz I can see flicker and with Freesync and BFI I am able to see flicker again.

Are you sure freesync is still active when in BFI mode? Test it with a game that has smooth scrolling and cap your FPS to 20FPS below the refresh rate. See if there's jitter/microstutter. If there is, then freesync doesn't really work.

The fact that you can even enable both on this monitor at the same time is interesting. It shouldn't be supported.

Best way to test this is with Frog Pursuit - use white line on black background pattern, press F to toggle fps limit slider. See how it behaves. If u see constant tearing in X-170Hz range than it's not working.

But by purely observing camera-screen flicker frequency fluctuation it would suggest it works.

I was able to find a slow motion option for my phone camera. Here is the Forg Pursuit with different framerates.

BFI AND VRR SLOW MO https://www.youtube.com/watch?v=5U3BGVGPBtM

It seems to do something, Now the question is how does it look like, good, bad? Is it worth using?

What were the steps to get to BFI + FreeSync? Did you just enable aim stabilizer, then switch on FreeSync? I can get someone to double-check this, any extra info you can provide would be a huge help. Thanks!

It's possible this is an undocumented "Aim Stabilizer Sync" like the FI32Q and M32Q, that is also in the M27Q.

From the video it looks imperfect quality, but might be good for low-latency strobing at consistent framerates at certain frame rates. Too bad it doesn't appear to support single-strobe 60Hz strobed VRR, which would be perfect for emulators.

On the M32Q it was really unstable below 85Hz. I'll see if someone can take another look at the M27Q. Even if it's not perfect, it's nice to see manufacturers starting to play around with these features.

Hi I did return the monitor but I switched back and fourth between the settings. With BFI enabled the monitor was not usable since there was a double image behind the ufo and sadly the overdrive is locked the highest settings.
So I tried with BFI + Freesync enabled, then with freesync only, then with BFI only. The strobing effect only occurs when BFI is a 170hz or when I have BFI and Freesync enabled.

Just noticed gigabyte updated their monitor list and apparently there are two revisions of M27Q and M27Q P. For second revision they list Aim Stabilizer Sync as a feature. Perhaps that could be you were able to make it work.

M27Q 1.0 https://www.gigabyte.com/Monitor/M27Q-rev-10#kf
M27Q 2.0 https://www.gigabyte.com/Monitor/M27Q-rev-20#kf
M27Q P (new panel) https://www.gigabyte.com/Monitor/M27Q-P#kf

Also there is a bug on some gigabyte monitors (M32Q) where if u enable aim stabilizer first and freesync second u get a single strobe vrr. Something similar could of trigger this to work.
