I'd like to buy this product: http://www.acer.com/ac/en/GB/content/model/UM.HX3EE.001
Is there a way to know what are the dimensions (in centimeters) of the height and weight of the display?
Ok. I'll post my calcs, since you claim I'm a retard.
-|c^2=a^2+b^2 => b=sqrt(c^2-a^2)
a=sqrt(c^2-a^2)*9/16 => a^2=(c^2-a^2)*(9/16)^2 => a^2=c^2*(9/16)^2-a^2**(9/16)^2 =>
=> a^2+a^2*(9/16)^2=c^2*(9/16)^2 => a^2 [1+(9/16)^2]=c^2*(9/16)^2 =>
=> a^2 = c^2*(9/16)^2 / ([1+(9/16)^2]) => a = c*(9/16)/(sqrt(1+(9/16)^2))
a = 27*(9/16)/(sqrt(1+(9/16)^2)) = 13.2370534701 =>
=> b=sqrt(27^2-13.2370534701^2) = 23.5325395024
Also: since you're a glorious intellectual, you should know that those are properly called PPI, not DPI, since monitors don't have points but pixels (yes, I've googled it and I'm learning...but...you're a glorious intellectual!).
Are you this didactic in bed too, anon? T-teach me a lesson senpai.
27" 1080p has big pixels. So big that text looks a bit blocky.
23" 1080p has the same number of pixels but they are smaller so text is more crisp.
27" 1400p has more pixels and they are even smaller which makes it better for reading.
Of course if pixels are too small text will be unreadable and you have to change the resolution in the OS to something less than the actual resolution of the display, and the OS must have support for scaling (win10 does this ok. not great but ok). This is true for let's say a 23" 4k monitor.
23" 1080p or 27" 1400p are just about right. Pixels are not too big and not too small.
All of the above work well for video.
The best thing to do is to go into a store and look at a 27" monitor with 1080p and one with 1440p and see the difference and decide which you like more.
If pixels are very very small and the desktop resolution is set to the maximum (native) resolution of the display then the text will be very small.
The characters will be too small to read, unless your eyeballs are very close to the monitor.
High resolution also means more stuff (windows) can fit on your desktop but if pixels are too small everything will be very small so DPI is important.
You need to increase display size in tandem with the number of pixels
or use a different resolution than the native resolution (if you have lots of pixels and small display)
or you're screwed (if you have a small number of pixels on a large display) .
The monitor is 27" inches so this must be true:
We know the aspect ratio of the monitor and therefore:
We can substitute that in into Pythagorean.
w^2+(.5625w)^2=729 which simplifies to 1.316w^2=729"
729/1.316=~554=w^2, square root that to get w = 23.53"
23.53/16=h/9, therefore height = 13.24"
cool op. it is well known that 5^2 = 4^2 + 3^2 is.
4^2 = 16
3^2 = 9
guess which ratio the monitor has. 16:9.
we know that 5^2 which usually is 25 is now replaced with 68.6 cm as it says in the description. we know divide 68.6 through 25 and get 2.744.
now we 16 * 2.744 and 9 * 2.744 and get 43.904 and 24.696 cm for length and height. just to see if thats correct
b = 43.904 cm
a = 24.969 cm
d = 68.6 cm
You guys are both idiots.
Let x be the unit 16 and 9 are multiplied by to get final dimensions:
(16x)^2+(9x)^2=729 simplifies to 337x^2=729
