Retina displays and other high pixel density displays such as 4K TVs, 1080p cell phones, and Full HD+ tablets are being heavily marketed to consumers. Cut through the sales fluff and understand what it all means in a couple minutes!

I'm so glad you spelled "colour" correctly Diezel or B-Roll! That made me quite happy and was probably my favourite part of the video. I also love the professionalism on this channel for the target audience. It makes me feel like Linus is "at work", whereas the LTT channel feels like Linus and/or Slick and I are just kicking back with the nerdy shit we're into. Loving everything Linus Media Group is doing, keep up the fantastic work guys!

The PPI needed to match the average fovea cone density is in the 250 range from 2/3 feet viewing distance. So we're pretty far from the perfect PPI experience needed in games. You'd need 4K on a 17/18" screen or 8K on a 32 to 35" (both in my opinion too extreme as monitor sizes). Guess the best overall monitor experience with eyes comfort for extended period of times is 6K on a 24 to 27" monitor...or I guess that 5K with a high framerate would suffice on a 27" screen. So yeah I guess Apple got one right with the iMac monitors. Still exceeding the average fovea cone density I personally think is NOT useless as it adds even more details to the image, so fuck it. 8K G-Sync, 200 Hz, IPS (Or Oled or Uled) with HDR on 27/28" monitor is my bet for the PERFECT gaming monitor experience. Maybe 5 to 10 years from now?

Personally, i like AMOLED screens. When i compared my Note 2 screen with my friends iPad 4, my colors were more vivid and overall it looked better. The difference was actually quite big.

32" 1920x1080p monitor owner here. Couldn't agree more. I couldn't care less for 1200 or 1440p resolutions. 1080p has served me well for quite some time, and it still looks wonderful to this day.

It depends on the size of the display but nowadays 500+ PPI is what you should aim at if you want the highest appreciable quality in your smartphone.

I thought this was a very good over view. Though there is still lots of different aspects that make a screen more crisp but then we get very technical so it doesn't matter to much and we would just start confusing more people.

I have a 40" 1080p LCD TV, and I have been watching the TV series '24' on DVD. When I was watching it from about ten feet away, the quality looked really good. Now I have moved my TV behind my computer desk, meaning it's right in front of me. I tried watching 24 again, and it looked absolutely horrible! I could clearly see the pixels. I really need to get a 4K TV.

I can play most games on Ultra with my set-up on 1080p and it looks amazing enough already. I'm sure 1440p would look better, but I am more than satisfied with 1080p. Maybe when 1440p becomes the new standard I'll jump up to it, but til then I am fine with 1080p.

so is there any advantage at all to having a higher ppi? like a 27in 4k screen would probably be sufficient to be "retina", but would there be any noticeable difference whatsoever if it were, let's say, 8k? or is it simply, if you can't see the pixels, you don't need more resolution.

commercial mass production is always at least 5 - 7 years behind mature lab results. just because currently 400 ppi is high end, doesn't mean we are not capable of producing higher ppi. JDI already made a small display at 650-700ppi and it was almost half year ago. give it another few years, we'll see 1000+ ppi displays in the lab and commercially available in two years after that

Actually I was referring to a poll I found that Samsung alone sold twice as many devices as Apple (in whatever quarter they were looking at) and Apple still lead the market in total profit overall. Of course Samsung (and everyone else But Apple) has multiple devices, and everyone but Apple rolls out newer ones every 3-6 mos. So you're correct about the "premium pricing". And TBH, IDK if that included Tablets. it just said devices.
