PG278Q Hz Problem, need help please

[Al_Jourgensen]

Hello my friends

has promise, i feedback my experience.

First - I RMA the display, they brought my another one, i test it, same thing 85Hz top with the driver that you advise me, so i installed the last version of it, and i always have to try to create the 144Hz, even if it doesn't appear, so the NVCP, after close it and open it again, show me at least the 100Hz option.
If i try to create only the 100Hz, it goes "out of range" (unbelievable)

Second - I tried almost all the drives from 340 and above, same thing, with some, he only shows me 85Hz, then i try the same steps to create the 144Hz, same process has i described above, and when i close and reopen the NVCP, 100Hz are shown.

Third - I made a complete factory reset to my laptop, after this, and without any update installed, i plug in the display, 85Hz shown up, and then i try to create the 144Hz, sends me a messege, saying that the display doesn't support that refresh rate.

Four - I install the 340 Nvidia drivers that came with the cd of the display, and install the only drivers that he have, and nothing, same story from the beginning, 100Hz max, and doesn't let me create the 144Hz.

Five - I go to the store (Mediamarkt in this case) and saw one working, they have it plug in to a ROG tower with a GTX980, and they only tell me that they plug it in and that´s it, no drivers of the display where installed, and the 144Hz appears, with no problems.

So, i´m running out of options here, really this is the most strange thing that happen to me since i was born.....i really don´t know what else i can do, the only option left, is update all windows again to 8.1, and see if something changes (what i doubt), or RMA again the display, but i think that Asus might change it, but i think it´s the last time they are going to do it.....so i don´t know what to do.

The only option that i have left, is taking my notebook to the store (Mediamarkt), and plug it in that display that was working there, and see what happens.

I´m very frustrated with this situation, and i don´t know what else i can do beside this.

My notebook is an Asus G750JX, with a GTX770M, here are the full specs

When i get in to the store, and try my last resort, i will feedback.

If you have any other solutions, please just let me know...

Thank you very very much once again for all your attention.
