Can I disable the screen mirror on my monitor?

Hey everyone, I'm wondering if it is possible to disable the screen mirroring on my TV so that I have all the performance on the Rift.  I am not sure if the Rift was designed to send out both signals without it impacting performance, so if it was possible to turn the normal image from my television, I'd love to do it. 


Thanks for any help everyone:)

    No you cannot. There is no impact to performance, it is an exact signal mirror from the GPU, geometry and shaders are not redrawn for the screen again. Think of it as a simple video feed.

    ASUS MAXIMUS IX HERO | MSI AERO GTX 1080 OC @ 2000Mhz | Corsair Carbide Series 400C White (RGB FTW!)

    Awesome explanation, thank you - I've been somewhat worried about the monitor
    Intel i7 7700K (4.5 GHz); MSI GeForce GTX 1080 8GB Gaming X (oc 2100 MHz gpu boost, 11 GHz mem speed); 16GB Corsair Vengeance LPX DDR4 3200 MHz; MSI Z270I Gaming Pro Carbon AC (VR-Ready) mainboard; Samsung 960 Evo M.2 SSD + Toshiba P300 HD; Windows 10 OS; Valve Index and Oculus Rift CV1 - the latter nearly always using super sampling 2.0.

    This may help someone ;")  I have noticed an huge improvement with my self-build machine (with less stuttering and better overall VR) by doing the simple trick below,  even with the best system I knew to build at the time (My Kingdom for a 'K'.. anyone get that? LOL)   this helps,  so surely it would help even more on a lesser system (?)   I SURE WISH I had gotten MORE POWER - OR the GTX 1070...   If some one could look at my system-specs below and tell me my bottleneck(s) I 'd be most grateful!)
    SYSTEM: 
    (
    Gigabyte H270 Gaming 3 Rev2.0 MB,
    Intel Core i7-7700 (No bloody A, B, C, or... K...),
    16GB Corsair Vengeance LPX DDR4 2400,
     WD Black M.2 drive,
    Gigabyte Aorus GTX-1060 6GB,
    Power CTX 750M

    so to try to wring more out of each game,  I do things like:
    1) Change my 3 Monitors to 1.
    2) Change my Resolution from 2560x1440  to 1024x768 (even 16-bit..)
    3) Go into the NVIDIA Control Panel and the 3D APlication settings, and learn all the ones listed, how they affect VR (Most are best set at Applkication Controlled)  <--- On this step, if you can see the Oculus in the Multiple Monitor Setup screen!  Do optimizations while on THAT 'Monitor'!
    4) Check and see! TURN OFF 3D Vision 

    Hmm,. There's more,.  I have worked at Activision many years ago and learned to try to wring every conceivable ounce of power out of machines while building games in DOS in Autodesk 3D Studio (for DOS!)   I'll add to this as I think of the other things I do.

    Anyone know if removing 3D Vision removes VulkanRT ? This prevents Lone Echo loading. I don't see a direct link to those files in the package.

    Wow,  there should be no interplay between the two, 3D Vision is squarely NVIDIA ../   Simply making sure 3D Vision is OFF (unchecked) should be enough,  what do you mean by 'remove it'?

    The power is not wasted, like I mentioned above what you see on your TV or monitor is a simple mirror. The GPU is not redrawing the scene again. Dual GPU or more setups are tricky still and up to developers to implement correctly. Having each GPU send a frame to each eye causes a lot of latency and it all has to be in sync.
    Thats strange when i minimize the window the game becomes much more smoother! So i think it does indeed causes a performance drop in some way. Idk but i notice far better performance minimized.
