Question about receiver to pc setup with 120hz monitor and gtx 690

Not sure if this is the right forum to ask but here goes.

I have a 120hz monitor, a Yamaha rx-v473 receiver and a gtx 690. I couldn't do the usual video card to receiver, and monitor to hdmi out on receiver because then it was limited to 60hz refresh rate. So what I did instead was monitor to video card via dvi-d cable (gives me 120hz) and then video card to receiver via dvi to hdmi cable. After I do that I can see both monitor and receiver as separate "displays" in display options. So I mirror them and that gets me sound and keeps my 120hz refresh rate.

I tested sound (it did dts, dolby etc fine) and played a few games without issues but still have a few questions/concerns.

1 - Is this the best way to connect it with the setup that I have?
2 - Since second "display" is the receiver in mirror mode, would there be any impact to performance in video games?
3 - If I check the info on the monitor it shows 1920x1080 120hz, but if I check signal info for the receiver under HDMI it says 1080i, not 1080p. Is that something I can ignore? It cant be running 1080i at 120hz correct?

Thanks in advance for any replies.

  1. Best answer
    That is, in fact, your best option for your setup. It shouldn't be affecting framerate at all; if it is, then it's no more than one or two fps.

    Don't worry about the receiver - it's not running at 120Hz, and shouldn't be anyways. 1080i is probably the highest resolution it can accept, and it's working at 60Hz, just like a normal monitor would if you hooked it up as a secondary screen. You don't have to run every monitor at the same resolution or refresh rate.

    Thank you for clearing it up. So just to make sure I got this right, even though they are setup in mirror mode, the monitor is running 1080P 120hz and I can ignore that the receiver says 1080i since its just being used for sound, correct? It was just weird because when this receiver is hooked up to a lcd tv the normal way via hdmi it did say 1080p for signal info. Thats what confused me in the first place.
  3. That's correct, yeah. It's because a monitor (which is how your computer sees the receiver) sends a computer information about it's maximum resolution and refresh rate - it can't take an input higher than that and still display. That's why when you have the TV plugged in, it uses 1080p; because it can take that.

    Thanks again for your help so far. One last question. When I clone the receiver and the monitor via the nvidia control panel it mentions something like "cloning the focus display will reduce multi gpu performance". Since the 690 is a dual gpu card is that something I need to be concerned about?
  5. I haven't had experience with the 690, but I wouldn't worry about it too much; it's got MORE than enough horsepower to run three monitors, much less one 120hz and a clone.
