Did you select 'prefer max refresh rate' in Nv CP? I heard this fix working for others, that if monitor is set to 120hz, it will stick to that at idle but use higher in gaming.
I can confirm, that you're right. I'm running (as test) 60hz on desktop, browsing aso., and it still turn up to 144hz in games (dx9 and dx11 and OpenGL games). When shutting the game down it return to 60hz on desktop, chrome or whatever I'm doing. I got this to work this way in Nvidia's control Panel. In "Change resolution" I set the resolution to 2560x1440 at 60hz. And in 3D admin setting I set "preferred refresh rate" to "highest possible". Then the games are running with 144hz and desktop, surf aso is running 60hz with Gsync ON. NB: Maybe the names of the settings above is not the same as yours, as my Nvidia Control Panel is in Danish, and I translate just this to English, as I assume you don't read Danish :grad:

This just proves that Nvidia doesn't read it's own forums. This problem was reported awhile ago. Users were using the vBios tweaker to change the power states. Or setting their performance rates to be a lower refreshrate on the desktop.
I don't even know why those forums exist. They are completely useless in my experience.

Have you checked if you actually go back to 144Hz during gaming? I turned down the refresh rate to 120Hz, but my XB270HU showed it to stick to 120Hz Gsync even if I turn on a game (BF4 for instance). I then switched back to 144Hz on desktop too to get what I bought my hardware for during playing. At least the monitor's OSD states it doesn't go up to 144Hz and sticks to 120Hz, as I don't have a high speed camera I can't really check 😉
Yes mine changes properly when I change the setting in the control panel to use max refresh rate.

AMD should do the same with the R9 Fury/X/Nano Display Corruption issue
That did happen to me altogether 4 times, long time ago. Every time solved by replugging DP cable. Then I got lucky and DP connector/cable no longer created interference. Perfect experience since then.

When I had R9 290 super bad power saving when using 75Hz was one of those things that "forced" me to go back to NVIDIA. Memory ran at full blast which made the card run hotter and even things like watching video made the GPU fan to speed up (it was noticeable, sound and temperature wise). It's really annoying if power saving doesn't work properly when you use high(er) refresh rates.

It works fine at 1080p. 1440p and 144hz is where the issue is

That's why I have LED light everywhere. If I keep everything lit, it still eats as much as one forgotten incandescent light bulb. And I consider that energy saving from lights as way to feed other stuff. But one should note that every watt GPU eats is turned into heat. For some people it may be problem. 100W idle difference can be problem for others too (for people running system 24/7). In case of 24/7 system it costs like 11 Euro/month.
More like 6€€ (100W*24h*30days=72000WH = 72kWh, 72kWh(0,0456€/kWh+0,0311€/kWh)~5,50€) :3eyes:

Personally I would not care about the power usage seeing that I have all power states turned off anyway, but this is not the case for everyone. I have seen many complaints on the Nvidia forms, but they now choose to do something about it after it's pretty much been an issue since launch?

Not a problem for as mine is always set at 120hz can't really tell the difference between 120 and 144hz so 120 is fine

I noticed that years ago, that's why I use 120Hz instead 144Hz

I have to try this today. I didn't relate the inspector's setting to this behavior, must have missed this one. Thanks guys! (Also, no need for a miraculous 'fix' then... there's our sollution.)

Well now I'm curious how much it does really cost at you guy's places.

100w 24/7 a year would cost me around 72€. Well actually should be less because I have an offer and I took the normal prices from the website of my electricity company.

No it doesn't. My 980Ti still goes to 963 Mhz if I run 1080p @ 144 Hz.

High pixel clock rates cannot be maintained at idle card clock speeds, be it nVidia or AMD. Basically, 144Hz monitors cannot run with 150MHz core clock, not yet anyway. Having dual monitors always had card clock speeds at low 3D mode. I remember having this "issue" back from CRT monitors days. Graphic cards where pretty loud back then and it was one of the reasons I ditched dual monitors. Having GeForce 4200Ti run @65 Celsius all the time (in idle) wasn't very fun since fan was pretty noisy. It was even worse with X1800XT... Now, with G-Sync there shouldn't be high pixel clock rate but something is generating it apparently.
