+ *
+ * I am clearly going to have to explain this one more time, forever.
+ * Let's see if I can't write it authoritatively once and simply answer
+ * with a URL from here out. (As always, use of the second person "you"
+ * herein is plural, not singular.)
+ *
+ * EDID does not reliably give you the size of the display.
+ *
+ * Base EDID has at least two different places where you can give a
+ * physical size (before considering extensions that aren't widely deployed
+ * so whatever). The first is a global property, measured in centimeters,
+ * of the physical size of the glass. The second is attached to your (zero
+ * or more) detailed timing specifications, and reflects the size of the
+ * mode, in millimeters.
+ *
+ * So, how does this screw you?
+ *
+ * a) Glass size is too coarse. On a large display that cm roundoff isn't
+ * a big deal, but on subnotebooks it's a different game. The 11" MBA is
+ * 25.68x14.44 cm, so that gives you a range of 52.54-54.64 dpcm horizontal
+ * and 51.20-54.86 dpcm vertical (133.4-138.8 dpi h and 130.0-139.3 dpi v).
+ * Which is optimistic, because that's doing the math forward from knowing
+ * the actual size, and you as the EDID parser can't know which way the
+ * manufacturer rounded.
+ *
+ * b) Glass size need not be non-zero. This is in fact the usual case for
+ * projectors, which don't have a fixed display size since it's a function
+ * of how far away the wall is from the lens.
+ *
+ * c) Glass size could be partially non-zero. Yes, really. EDID 1.4
+ * defines a method of using these two bytes to encode aspect ratio, where
+ * if vertical size is 0 then the aspect ratio is computed as (horizontal
+ * value + 99) / 100 in portrait mode (and the obvious reverse thing if
+ * horizontal is zero). Admittedly, unlike every other item in this list,
+ * I've never seen this in the wild. But it's legal.
+ *
+ * d) Glass size could be a direct encoding of the aspect ratio. Base EDID
+ * doesn't condone this behaviour, but the CEA spec (to which all HDMI
+ * monitors must conform) does allow-but-not-require it, which means your
+ * 1920x1080 TV could claim to be 16 "cm" by 9 "cm". So of course that's
+ * what TV manufacturers do because that way they don't have to modify the
+ * EDID info when physical construction changes, and that's cheaper.
+ *
+ * e) You could use mode size to get size in millimeters, but you might not
+ * have any detailed timings.
+ *
+ * f) You could use mode size, but mode size is explicitly _not_ glass
+ * size. It's the size that the display chooses to present that mode.
+ * Sometimes those are the same, and sometimes they're not. You could be
+ * scaled or {letter,pillar}boxed, and that's not necessarily something you
+ * can control from the host side.
+ *
+ * g) You could use mode size, but it could be an encoded aspect ratio, as
+ * in case d above, because CEA says that's okay.
+ *
+ * h) You could use mode size, but it could be the aspect ratio from case d
+ * multiplied by 10 in each direction (because, of course, you gave size in
+ * centimeters and so your authoring tool just multiplied it up).
+ *
+ * i) Any or all of the above could be complete and utter garbage, because
+ * - and I really, really need you to understand this - there is no
+ * requirements program for any commercial OS or industry standard that
+ * requires honesty here, as far as I'm aware. There is every incentive
+ * for there to _never_ be one, because it would make the manufacturing
+ * process more expensive.
+ *
+ * So from this point the suggestion is usually "well come up with some
+ * heuristic to make a good guess assuming there's some correlation between
+ * the various numbers you're given". I have in fact written heuristics
+ * for this, and they're in your kernel and your X server, and they still
+ * encounter a huge number of cases where we simply _cannot_ know from EDID
+ * anything like a physical size, because - to pick only one example - the
+ * consumer electronics industry are cheap bastards, because you the
+ * consumer demanded that they be cheap.
+ *
+ * And then your only recourse is to an external database, and now you're
+ * up the creek again because the identifying information here is a
+ * vendor/model/serial tuple, and the vendor can and does change physical
+ * construction without changing model number. Now you get to play the
+ * guessing game of how big the serial number range is for each subvariant,
+ * assuming they bothered to encode a serial number - and they didn't. Or,
+ * if they bothered to encode week/year of manufacturer correctly - and
+ * they didn't - which weeks meant which models. And then you still have
+ * to go out and buy one of every TV at Fry's, and that covers you for one
+ * market, for three months.
+ *
+ * If someone wants to write something better, please, by all means. If
+ * it's kernel code, send it to dri-devel at lists.freedesktop.org and cc me
+ * and I will happily review it. Likewise xorg-devel@ for X server
+ * changes.
+ *
+ * I gently suggest that doing so is a waste of time.
+ *
+ * But if there's one thing free software has taught me, it's that you can
+ * not tell people something is a bad idea and have any expectation they
+ * will believe you.

+ *
+ * The RANDR extension as of version 1.2 does allow you to override
+ * physical size on a per-output basis at runtime. We even try pretty hard
+ * to set them as honestly as we can up front. The 96dpi thing people
+ * complain about is from the per-screen info, which is simply a default
+ * because of all the tl;dr above; because you have N outputs per screen
+ * which means a single number is in general useless; and because there is
+ * no way to refresh the per-screen info at runtime, as it's only ever sent
+ * in the initial connection handshake.
