Canon 650D - sensor size?

[akiskev]

I would actually DIE for a 300ppi screen...

You are not going to die young. That's for sure.
Consumer 5750x3237 22" / 6276x3533 24" monitors will take a while till they hit the shelves. When this happens, you will finally be able to rest in peace.

You can strap 4 screens together pretty much seamlessly which would do that for you

Dear brian you 're missing the whole point of ppi. Read more carefully next time!

Just giving the computer geek answer to getting large screens at high res. Agreed at the moment they havent managed more than 200dpi but it wont be long.

Virtual desktops will be with us for some time yet

@askiev: Hah! Well, at least I have a nice long life ahead of me, seeing as I want one of those 300ppi puppies in 27" 16:9 format! I guess that would be...what, 7660x4309? Yeah, doubtful I'll see that in the next decade, unless something really spurs along high density screen development. Oh, and did I mention...I want it as an OLED?

My desktop is currently 1980 x 2160 with 2x 24inch screens. Oled would be nice - roll it up and put it in a draw when not using it

Its not about the number of pixels, its about how densely those pixels are packed. I want 300ppi, not just a certain number of pixels. 7660x4309 only comes into the equation because thats the dimensions of a 300ppi 27" screen. Multiple screens increases pixel count but does nothing for pixel density. I am not so much concerned about rolling up my screen and storing it in a drawer, or having it be thin enough to be translucent. I just want it to be AMOLED because those screens are amazingly bright, clear, accurate, dense, and technologically superior to RGB-LED, not to mention they are one of the key reasons 300ppi+ devices exist at all (iPhones with Retina are around 300ppi OLED devices.)

Density is a minor issue, just an improvement in technology.

Already you can buy 15inch screens in 1920x1080. The hold up at the moment is getting more pixels on a screen rather than the size of the pixel. Virtual is the current trend ( mostly because of the commercial  benefits for large banks etc). A room full of traders with 4 or more screens strapped together is quite impressive.

[c-law]

Seeing as the new iPad is 264ppi you could always rig 3 of them together and get the equivalent of one 19.1" 20:9 display.

All for the low low cost of ~$1250.

I think the question of MP size has already been answered
