27" iMac w/Retina 2014 v 15 color picture Quality +

[AlexB23]

Hi everyone,

I'm using a mid 2010 Mac book Pro 13 inch that I have had for six years now and has been fantastically reliable. I'd love to have a bigger screen which I guess is an understatement more pleasure in viewing, an upgrade in quality all around ,more power if I needed, but mostly visual enhancement of experience.
I think the retina model is definitely for me. My budget is about 450 two 650 I don't care about cosmetics I like to tinker and fix things I changed the hard drive to and SSD and put it in more RAM on this old thing. if this screen was cracked I'm sure I could replace it anyway I'd like some advice on buying, please. what companies are best and most trusted I could buy on eBay also
My question concerning the 2014 model and the 2015 model with the retina is Color quality is the quality better in the 2015 model? I think there was an upgrade in color in 2015. Does anyone have a comparison. Color is important to me I have a sensitive I and can distinguish Quality.
Any advice would be most appreciated, of any kind.

Thank you
Alex

Their displays are nearly identical. The 2015 has a wider colour gamut, but viewing sRGB content on both will be basically the same. The P3 colour space only matters for content in the P3 colour range which most content out there is not. Both look fantastic

Thanks for being helpfulm I'm not informed about what "content in the P3 colour range"really means ,But I mostly like watching movies and a lot of really old color and black & white films on youtube . so the 2014 may be a little cheaper to buy . both are upgradeable yes .
where is the best place to buy ?
do people sell on the forum?

So in a digital image or video file one might include information to the OS/application about the “colour space” of the file. This will allow a colour value of, let’s say R=0.2, G=0.5, B=1 to mean something different when shown on the display relative to another colour space, so that things look ”correct” regardless of how the content was mastered.
A P3 display like the iMac 2015 will have the same maximum for blue as sRGB but much greener green, and slightly redder red. So if a picture just directly used its values on the display, if the artist or photographer mastered the image for sRGB which is the more common colour space and set their green to 100% for a specific area, it may look way too green on a P3 display. Going the other way though, they may have mastered a TV show for NTSC. SO with the information that it’s in the NTSC colour space the Mac will need to do the opposite and stretch the colour space.

macOS is generally really good about ensuring content looks correct regardless of monitor; Windows less so, meaning that a technically better monitor on Windows can sometimes display things looking worse because it doesn’t properly translate the colour spaces.

On macOS if a file does not have colour information, it defaults to sRGB because that is by far the most common colour space, so it’s what’s most likely targeted when nothing else is specified. This is also default behaviour for most other systems like Adobe’s Creative Cloud suite, which does their own thing on both Windows and macOS rather than relying on the OS; For the aforementioned reasons on Windows one might imagine.

As for upgrades; Well, it depends. You can’t change the GPU in either. Though the CPU is socketed, the RAM is easily accessed and the disks should be upgradable too, as long as you stay mindful of the temperature sensor less you want constant max fan speed.

Would have no idea about the best place to buy, but yeah, sometimes people sell on the forums; There should be a dedicated marketplace forum for it I believe.
