Hello Microscopists,

Recently George advertised on 4k monitor. How about 5k one!
Please comment if anybody  had their hands and eyes (!) on
the first 5k 27" Dell monitor


http://microsoft-news.com/dell-ultrasharp-27-worlds-first-display-with-ultra-hd-5k-resolution-will-be-available-for-pre-order-from-nov-13th/
http://accessories.us.dell.com/sna/productdetail.aspx?c=us&cs=04&l=en&sku=UP275K3


Pricewise $2500 is a lot. I grabbed  Seiki 39" 4k TV/monitor on $299 sale,
and did not regret (they are long gone for this price). Performance/price
ratio  is fantastic. The limitation is that 4k resolution only through HDMI
(special cable required) and only at 30Hz which is fine for static images
or slow movies.

I wonder if companies are actively working on compatibility of their
software with ultra high resolution monitors like 4k, 5k. I can tell
that Windows 7 does not look nice at 4k. Moreover, it seems that
there are no widespread data transfer protocols and video cards
to provide 3840x2160 picture at 60Hz.

Cheers,
Arvydas

Dear Deepak,

if your colleague tries to stain lipid droplets -not vesicles in the strict
sense- these are specifically stained with BODIPY or NileRedO. CARS is
another very good option if you have the tools.

Hi Arvydas

Slightly different topic, but:

As it is a LCD monitor, this means that there are now video rate nematic liquid crystal
displays with 5k x 5k pixels.

This is great for holography, optical phase conjugation, structured illumination and many
other applications using SLMs.

Nice, so one can either gut one of these monitors or wait till Holoeye or another company
makes a kit using that SLM and a custom driver.

Quite exciting!

Best regards,

Reto

Hi Reto,


you overestimated the resolution of the monitor . It does not provide
5kx5k-25M pixels, that would be too big jump in LCD monitor technology as
would either  require 0.2mmx5kx1.4=1.4m=56" diagonal size LCD screen
at common dot pitch 0.2 mm or 27"x25.4mm/1.4/5k~0.1 mm dot pitch
(the latter is already achieved in tablet/smartphone screens).


These terms 4k, 5k redolution are  a liitle  bit  quantitatively confusing as they mean the order
of pixels in a horizontal row. In practical implementation of  LCD TV/monitor
industry  4k usually refers  to  4x full HD resolution  1920x2 by 1080x2 yielding
only 8.3M pixels (~half of 4kx4k=16M). The Dell  5k monitor has  5120 x 2880=
14.7M pixels (still 40% short of 25M).


Cheers,
Arvydas
