Anyways, I am running a Digital Storm Behemoth laptop with two 8GB GTX 980m's in SLI, 32GB RAM, i7 4980MQ, etc. and a newly purchased Acer XG270HU 1440p 144Hz monitor, which I am connected to through a Mini DisplayPort to HDMI adapter (I'm just using this while I wait for my single MDP to DP cord) and both the adapter and cord are rated for up to 4K.
Now, when I was using only the HDMI cable I was able (for brief periods of time) to run my monitor at it's full resolution with no real problems for the first day, but it soon started to become very unstable with games, giving 'NO SIGNAL FOUND' black screens nearly every time I attempted to launch a game or messed with settings. So I ordered a MDP to DP cable which is still not here, and in the mean time I grabbed the above mentioned MDP to HDMI adapter, which is much much much more stable, but will not at all let me go beyond 1080p at 60Hz, even after trying your 5 step process with CRU and also adding the HDMI patch you linked.
I'm pretty positive I'm just not using the utility right, but I can't find any sort of 'beginner walkthrough' for fools like me. Any advice? I'm hoping that when my cord arrives it will fix my issues, but it would be nice to have a better grasp on the situation in any case.

2560x1440 @ 120+ Hz requires DisplayPort 1.2, dual-link DVI (with the pixel clock patch), or HDMI 2.0 (if the monitor and video card can handle that). Do not use adapters. DisplayPort to HDMI is not likely to support HDMI 2.0.

Blackouts usually indicate a signal-quality problem. You need a high-quality cable for that kind of bandwidth. I would avoid using HDMI because HDMI 2.0 is still relatively new and may not be well-supported. DisplayPort is the best option.

So a new day, a new monitor, and new problems. Hooray. I got sick of the issues being presented to me by the XG270HU and exchanged it for an ROG Swift. Which DOES support G Sync through DP, however I only have a Mini DP on my system, which as far as I've researched SHOULD work. From my PC I'm running a single MDP male to DP male cable into the monitor and getting no signal as of right now. The driver disc is saying that it cannot find any hardware to apply the drivers to, but shouldn't the screen still be displaying something despite that? any help is appreciated.
