You CAN see a bit of a black frame in the picture though. The blur probably makes it look thinner than it actually is.
You could be right... I'm merely paraphrasing what folks at F Y J S were speculating, who never claimed it was frameless. So far, so blurry, in a manner of speaking.
Then again, the 'frame' could just be refraction from the edge of the HUD, especially if the HUD is thick and the edge has a different finish (a la glass lens).
But then again, there does appear to be a frame of some kind holding up the HUD from the bottom, but the said frame does not completely wrap around the HUD in the same manner found on '2001' and '2002/3'. The frame appears to end around the horizontal centerline of the HUD. The portion of the 'frame' above the centerline could just be the aforementioned edge refraction.
Assuming this new HUD exists, there must be a photo somewhere on the interwebs. Oh my and silly me indeed, now would you look at that: it's the very last photo in my previous post.
Back to the blurry photo of '2011', the HUD appears larger in relation to the rest of cockpit instrument cluster, don't you think? Then again, this could just be an optical illusion: it's all about damn angles and contours.
Or is it, assuming the photo is not 'excessively" re-touched?
Hmmm indeed...
That's enough speculation for today, back to Sein und Zeit.
P.S. pardon my front-loaded cheekiness. Apologies if it came across as being snarky sarcasm. Cheers!
