Let me just start by saying that I'm new to this kind of thing and messing with PCs in general, so I apologize for what may seem to be a lack of knowledge at any point. 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.

thanks in advance

BEFORE YOU CONTINUE ON, are you sure you have an XG270HU or an XB270HU?
The XG270HU already has a HDMI port, so why are you using a DP to HDMI cable? Just use HDMI ...

And if this *IS* indeed an XG270HU......this is a FREESYNC monitor. And you are using a GSYNC video chip ..freesync/adaptive sync does NOT work with Nvidia cards, so...why did you buy that monitor? Return it and get an XB270HU...(IMO)

*IF* This is a GSYNC monitor (the XB270HU), then read on.

ToastyX will have to help you here, but I can tell you directly that you are probably SOL. That monitor does NOT have a hardware scaler and also does NOT have HDMI capability (probably due to the missing scaler, which is handled by the video card directly). The scaler is a Gsync module, which current versions only support Displayport.

If you want a console compatible monitor, you need one with a traditional scaler and HDMI ports. Everyone I have seen who has been trying to convert DP to HDMI on Gsync monitors has run into problems.. The other person had an Acer XB270HU. he tried to use a DP to HDMI $30 adapter (not sure if this is active or passive) and he got "no signal" on his Playstation 4.

This would not happen with a monitor with a native HDMI port.
Sorry if I'm confused but I still have no idea why you purchased a freesync monitor to use with an Nvidia video card/laptop...

Any other HDMI problems with the freesync monitor, hopefully toastyX will be able to help.
