Hi guys,
I've recently sold my tablet and mac for a surface pro 3 and have been surprised to see a pretty huge difference in terms of the colour output from the display. On my 1080p old-ish lcd monitor on my desktop, many colours images on flickr produced by certain high end crop sensor cameras always seem less "defined" compared to many samples from a picture coming from a full frame sensor (especially the Canon and Sony's). However, when I use the SP3 to browse flickr, the differences seems to vanish. Colours seem more contrasty (and not the oversaturated type of contrasty) and the bokeh factor doesn't seem to appeal to me on this display anymore. Could it be because of the difference between a 12 inch screen vs 20+inch screen?

I always view pictures on flickr before buying a particularly body/lens to see the potential of a particular lens/body, and I'm now extremely pleased with what Fuji/Olympus cameras can produce because of viewing sample jpegs through the SP3 screen. My question is whether or not the differences can be attributed to the display quality of the SP3 or just the size of the thing.

Is the SP3 display a good display that shows off the potential of the Oly/Fuji files, or are the merits of FF images being rendered negligible because of the smaller screen?


how do I know which to trust, the monitor I have on my desktop or the SP3 display for judging image quality?


Thanks.

simple answer to your question, YES.

lets put it this way, turning it to a physical term....
printing a 8R(or extreme way, a 4R) vs a 12R poster print. which let u see more of the 'IQ' quality? (provided the DPI remains at 300dpi.)

but if a 8R with 300dpi compared with a 12R with 75dpi then its a imbalance comparison. something similar with your case.

i meet a customer yesterday, which give me a time of hell, egoish and stubborn to listen my explanation of PPI. he insist why his 24inch monitor is blur, because he compare that 24inch FHD display with a FullHD 5 inch phone. well, the pixel pitch is high, hence packing in heck of sharpness details. but again, you wont be able to see the larger picture* hence things like bokeh or the 'depths' of field, arent noticeable since everything is compress down to a smaller screen.
so to gain a good view of IQ, not only size but the PPI of monitor plays both roles.

another answer would be get a good 27inch(upsize) 4k(high dpi) monitor and it will blew you away.

(there are many other roles of IQ of displays(monitor) too, like color accuracy, color gamut, and delta e)

Actually another explanation is....is the monitor screen matte or glossy?

Monitor is matte while my surface pro 3 is glossy

Thanks! Will I understand PPI to some extent, but does PPI affect our perception of colour accuracy?

Yeah I think what you said makes sense: Bokeh seems to be more pleasing when viewed on a bigger screen.

PPI is just density, it affect so called "sharpness"...

but then when go into reallllly deep into the topic, the shape and arrangement of the RGB diod will affect how ppl 'see' sharpness(details) too.

then another factor will be viewing distance, the closer you get to the display (say hand phone are 20cm-40cm from your eye, vs monitor distance of 0.6m-0.8m

that why some people, can see rgb layer of diods on Asus zen phone 5, it felt like CA, where the red and blue looks like hazzy seperation.
so, if one day we reach a 2000ppi density, we will need very strong microscope to able to see the diods

color accuraccy are depend on the builds of the diods,
first it has to able to filter out which wavelength of light. producing which amount of gamut(eg; 67% of srgb, or 97%srgb, or 80% of adobe),
only then you require a colorimeter to map the color to its accuraccy. < this part meaning building a color profile for the monitor.

wtf wrong with me. hahaha please replace all DIODs to film transistor and color filter array* LOL, lcd dont have diods.... think too much of camera sensor...

Quality of the display panel would be the key factor for color accuracy, not so much of the PPI. For devices like SP3, you would be able to calibrate the color using devices like Spyder from DataColor.

Like what ieR mentioned - PPI is just density, it affect so called "sharpness"...

Same image, same screen size but the higher PPI display will make it feel like the image is sharper.

Theres your answer. Matte monitor tend to desaturate color.
