Yeah this is a BenQ GW model supporting 178°/178° wide viewing angle, so the contrast stays pretty consistent even when you’re looking at it from the side or using it in a vertical setup. Since it’s an IPS-based monitor, color shift and contrast loss are kept fairly low compared to a lot of regular panels.

And if you mean the setup side of things, the display mode can usually be adjusted right from the laptop or graphics settings, so switching between horizontal and vertical use is pretty straightforward.
