The screenshots in this review show a single taskbar across the bottom as you'd expect with a single screen. If Windows were treating it as two screens you would expect the clock and systray to be in the middle of the screen, at the bottom right corner of the left half.

I don't know at what level that problem is being solved, but it's getting merged to a single display device somewhere.

FWIW my UP2414Q at 60Hz with left/right driven by multi-stream transport hasn't had any color consistency or sync problems.

Windows has builtin support for multi monitor task bar since Windows 8 ;)

As for issues I would assume you don't have color profiles and aren't gaming on that monitor? Because while they aren't super common they do happen on the dual DP displays.

I've calibrated it with a Spyder 3 Pro and not had issues.

It hasn't been hooked up to my gaming computer for a while, so the tearing problems I can't vouch for.

Some discussion of Linux drivers here https://devtalk.nvidia.com/default/topic/982568/-feature-req...

It discusses the TILE property communicated over EDID informing the drivers that the two signals should be merged into one panel, which is apparently being done automatically for 4K displays in Linux but not for 5K.

Since I can't find any similar complaints on the Windows side, I would assume that these are correctly tiling automatically at the GPU level, not using the multi-monitor taskbar.

Again not the same monitor (and 4K instead of 5K), but I can confirm that I had a single taskbar across the bottom of my UP2414Q under Windows 7 before the multi-monitor taskbar support was added in Windows 8. No user configuration was required. Similarly, hitting Maximize will make a window cover the entire screen, not just half of it as if they were separate displays.
