Horizontal Image Tearing Issue

[Guest]

I have a XL2370, which runs at 60hz, and I know there is going to be some image tearing. The weird thing is that there is no vertical image tearing (or very little), but the horizontal tearing is very very bad. Is it normal for there to be significantly more horizontal image tearing than vertical?

All of this is with vsync disabled. Sorry, I should be more clear on what exactly I mean. By "horizontal tearing" i mean the tearing that occurs when you move, say a window, only side-to-side quickly, and vertical tearing when you move it only up-and-down.
