Given that the L206WU is based on familiar TN+Film panel technology and that the real interest factor is the DisplayLink interface, we'll keep the panel pedantry to a bare minimum.
Suffice to say, there are no significant horrors apparent in our objective test suite where we found good extension evident when rendering colour scales. However, the black and white tone scales do exhibit a touch of compression and there's also a touch of banding when rendering colour gradients, it must be said.
Likewise, the vertical viewing angles are pretty ordinary and as a TN+Film display, it will never be as vibrant and punchy as a VA monitor nor as accurate as an IPS panel - these things are a given. However it is a solid enough screen of its type with decent contrast and fast response.
On a final note, the L206WU also suffers from a very minor case of pixel overdrive-related inverse ghosting and it's so slight you'll only notice it under very close inspection, and is unlikely to be a problem for most users.
