Out of Range on screen but screen still works?

I'm having issues with a monitor where if I push the Hz over 75 on any resolution, there appears a blue box in the middle of the screen saying

"Out of Range"

But I can still see everything except what the box ubstructs.

I can go do the ufo framerate test, and it shows I'm doing 80hz, and I don't have any frame skipping with the frame skip test.

I'm using DVI-D into a Saphire R9 290 tri-x.

My question is, is there a way to make the screen not display this?

It works fine otherwise, and 75hz is all well and good, but it'd be sweet if ther was a fix for something like this.

I poked around and made a new EDID and stuff, but to no avail.

Any help would be appreciated.

The monitor is an Envision G918w1 @ 1440 x 900.

I will add a picture here shortly, I need to find my phone to take a pictgure of it, because obviously a screencap doesnt grab that shit.
