Will be gaming on the BENQ at 120hz/1080p.

Id like to use a dual monitor setup (only for web browsing/watching hulu while I game etc), is it possible to do this allowing the BENQ monitor to run at 120hz while the other (HP) simultaneously runs at the 60hz? Performance hit?

If so how should I physically wire it? Should I just use a dual-link dvi cable for the BENQ and a regular HDMI cable to the HP?

Additionally: Is it possible/is it a good idea to: maybe run the HP monitor using the onboard motherboard/haswell HDMI output; leaving the GTX 770 to run ONLY the BENQ? Performance?

If not should I go ahead a disable the onboard/haswell hdmi in BIOs?

Thanks for your time, I hope this isn't too confusing :pt1cable:

I recommend the above MSI GTX770. I looked at a lot of reviews. The ASUS one is also very good, and the EVGA with ACX cooler is fine. I think the MSI is overclocked higher than the Asus by default, but the Asus can easily match it with a slight overclock so either the MSI or ASUS (plus overclock) are my two recommendations.

*Note the MSI card (and possibly all GTX770's) has a dual-link and single-link DVI output. Therefore I recommend using a dual-link (and dual-link cable) if a high-res 2560x1440 or above monitor and the single-link to the second 1920x1080 monitor. If both monitors are 1920x1080 then it doesn't matter which DVI output you use. No reason to use HDMI.

Hi,

1. It's not feasible to use the HDMI output on the motherboard. While it's possible with Virtu MVP, it's quite buggy software and I gave up. It also introduces a small performance hit of between 5 and 15%. Basically the graphics card has to send the processed data back through the motherboard then out the HDMI connection.

2. HDMI monitor input:
It's common to have both a DVI and HDMI input, however sometimes (always?) that HDMI connection is the same as an HDTV's. There are "PC" connections and "HDTV" connections. Not a huge deal, but mostly requires fixing any overscan issues, as well you can't change the resolution in a game (you're locked to 1920x1080 and you configure that in the HDTV part of your video drivers).

*HDMI inputs in monitors may state "HDCP" compatible. That's important if you want to attach a BluRay player or likely a console that require that (High Definition Content Protection or similar name).

3. 60Hz and 120Hz at same time?
Apparently YES.
Someone else stated they had two monitors working, one at 60Hz and one at 120Hz. You can probably GOOGLE for further references on that.

4. SETUP:
probably something like you said:
a) Dual-link DVI from GTX770 to main monitor
b) HDMI from GTX770 to secondary monitor

*if you are NOT connecting a console/DVD player to the second monitor as you say, then it would likely be best to use the main DVI input and an HDMI->DVI connector or DVI->DVI connector if you have another DVI output on the graphics card (probably single-link only but that's fine. dual-link is only required for 2560x1440/2560x1600 and any resolution below that, I think but don't quote me.).

5) onboard video:
This is provided via the iGPU which only some Intel CPU's have. There's a list somewhere. Since there's no reason for you to use that that I can think of, just disable it in the BIOS and don't bother installing the Intel GPU drivers for it. It's probably off by default in the BIOS. See your motherboard manual.
