So basically a display which internally downconverts all input data to 4:2:2 should be considered faulty, cause it definitely loses quality for computer and game input content.
Well in reality you lose almost nothing. On Xbox and PS3 almost all “high end graphics” games render at 720p or even lower resolution and upconvert graphics to output resolution. This has much greater impact on quality than 4:2:2 processing. Even if some games use FULL-HD resolution they do not render enough information to show difference between 4:4:4 and 4:2:2 (low resolution textures, anti-aliased edges, even procedural texturing cannot run at full res, because of the aliasing).

Only PC-users using they TVs as main monitors will see difference between 4:4:4 and 4:2:2 and only in really bad cases (like red text on black background). And they are less than 0.1% of the market...
