Hi,

I am having an issue switching back and forth between a Gsync monitor and a non-gsync TV.

For my setup I alternate between my desk (One gsync monitor, one non-gsync monitor) and my bed (non-gsync tv) all hooked up to the same PC.

I recently built a new PC. Since switching, I have noticed that when I swap between the two setups (using displayfusion keyboard shortcuts) youtube videos are choppy in Chrome and Edge.

Turning off gsync and restarting the browser fixes the chopiness. Turning Gsync back on makes it come back. With my old PC I had this problem initially but was able to fix it by turning off G-sync in the Nvidia control panel.

Now display fusion doesn't seem to track the switch and I have to do it manually every time.

Does anyone know of a fix or have experience for this issue?

Thanks for the response.

When the TV display is choppy, display fusion shows the correct 60hz refresh rate for the TV. If I turn off G-sync and restart chrome the choppiness goes away.

I found a possible work around that worked for a few days, though I'm not exactly sure how to reproduce it. It involved displaying desktop on the TV and extending the desktop to the G-Sync monitor (normally these two displays are never active at the same time). I disabled G-sync on the tv and restarted PC. Then switched displayfusion profile back to the G-sync monitor and re-enabled. This seemed to work for a few days and verified G-sync was working in games and video was not choppy when using the TV. Today I opened Nvidia control panel to mess with some color settings now its choppy again and the same steps don't appear to be working.

As more folks get variable refresh rate monitors I hope you will look at incorporating some functionality into displayfusion to handle this. You guys are experts at this stuff and I can't imagine anyone else figuring out a solution.

Any other insights? Thanks!

Thanks for the assistance and trouble shooting.

I spent some time this AM and have it working again (able to use keyboard shortcut to switch profiles between G-sync monitors and non-gsync tvs without stuttering in videos).

I'll check that next time it breaks, for now it appears to be working and stable and do not want to break it.

If anyone else has the issue, here are the steps that appear to clear it up. Not sure exactly why but its working for me.

Steps:
1. Use TV only as main display for PC
2. Extend Desktop to G-Sync Monitor (normally these two are never both on with my configuration).
3. Disable G-sync in Nvidia Control Panel, apply settings.
4. Restart PC
5. After PC Restarts do not open Nvidia Control Panel
6. Switch displayfusion profile to PC (Gsync Monitor + Secondary Non-Gsync Monitor).
7. Open Nvidia control Panel and enable Gsync.
8. Restart PC again.
9. Switch back to TV, hopefully no issues and can switch back and forth.
10. Hopefully issue is resolved until next time you need to tinker with Nvidia settings. Swapping profiles with Nvida control panel open seems to break it.

Love displayfusion and the work you guys do (and thank you for the support!).

I hope you will consider incorporating some features/settings for variable refresh rate monitors. As they are more widely adopted others will probably have issues and I think you are the only geniuses that can figure out a solutions.

Thanks

On your last question:

I can add that while functioning correctly (no stuttering and able to switch between profiles freely), the key board short cuts or changing profile manually within display fusion does not cause the stuttering to come back.

I perhaps have a similar issue. I have a new 38" G-sync monitor and two 32" non-gsync monitors. I noticed when I move the mouse fast on the G-sync, things get very slow. For example, I play overwatch on the G-sync monitor, and if I move the mouse fast, fps drop to like 11 (normally in the 100s)... if I stop displayfusion, it's normal. I have not tried disabling G-sync to see if that's the issue, but this thread might lead me to try that.
