Question / Help 2PC Stream(2nd gaming monitor makes tearing 144hz&60hz)

[stefan widén]

Hello.

So yesterday I setup my streaming pc with my gaming pc, everything went well.

But then today I bought a displayport to hdmi adapter, so I could use my second monitor again on my gaming pc. After that I get ridiculous screen tearing, so I tried to dc my 2nd gaming monitor and problem gone.

My main monitor got 144hz and 2nd monitor got only 60hz, my main monitor is using DVI, and capture card hdmi if that matters.

Is it possible to use 2 monitors with different hz like this or do I need to get another 144hz monitor? Since Im short on money any other solution would be great, except lowering my hz on my main monitor.

I use a avermedia c985 capture card & stream at 720p 60fps using a gtx 980 graphics card on my main monitor.

You can see the screen tearing here: http://www.twitch.tv/widdz/v/52341568

TLDR: No screen tearing when I only use 1 monitor (144hz) on gaming pc, as soon as I connect my 2nd montior (60hz) the screen tearing appears. Main monitor with DVI, 2nd monitor with hdmi cable in to a displayport-hdmi adapater.

Best regards - widdz

EDIT: It works when I have the main monitor on 60hz however, I really wanna use 120 or 144hz on my gaming monitor with a 2nd monitor attached.

There apparently is a way to force separate refresh rates for different monitors, on some nVidia cards. Not sure how as I've never needed to do it, but Google likely knows.

You're going to get massive amounts of tearing when using a 144hz monitor and a 60hz capture card, if you try to force the setup to run at 144hz. Without vsync on, the capture card will be seeing (and therefore capturing) torn frames. Even with vsync on, it will be getting off-rate frames and almost definitely get some tearing happening.

HDMI and DVI are the same thing, just with a different connector on the end. DVI has all the features of HDMI, including sound, and some more on top. All that DVI->HDMI adapters are is passive pin-to-pin form factor changers.

How is your capture card connected? You'd said that the main monitor is DVI and the cap card is HDMI; is that being converted and then converted back? Attached to a different output on the GPU and mirrored from the main screen? Connected as passthrough to the second 60hz monitor?

My capture card is connect to the hdmi output on my graphic card, then I clone my main montior with avermedia.
I noticed that the second montir didnt have anything to do with it, I used my main monitor solo 144hz and got tearing.

I wanted to try the "projector" thing in obs, but sadly the option aint there for me, not even on my streaming pc on both 32 or 64bit version.

Cloning the monitor to the HDMI output also needs to set a lower refresh rate; by default it will probably try to push both at 144hz. Though to be fair, it may still tear due to the refresh rate disparity. The only way to get clean video is to game at a refresh rate that your capture card can handle, and save the 144hz gaming for when you aren't streaming. Or spend about four figures on a cap card that can handle 144hz.

To avoid tearing, enable V-sync in game menus and check graphic's control settings to make sure v-sync is not forced off. Cloning a 60 Hz with v-sync enabled might slow down to 60 fps with smooth stream/record.

To use Projector in recent version of OBS, set display monitors to extended. Using extended monitors and OBS projector might not be a smooth 60 fps stream/recording when game is running less then 120 FPS.
