    hello all. ive actually made a account just to post this because this place seems like the best for apple fans to discuss topics. I currently have a 2012 27 inch imac with a gtx 675mx and ive been gaming on it for the past 3 years and had a blast!! Been running most games at 1440p on high settings and 60 fps etc. But, im looking for a huge upgrade and the r9 m395x plus 3.3 ghz quad core skylake seems perfect for this winter. Now going to a 5k screen, i definitely do not plan on playing games at anything higher than 1440p. So if anyone else plays games on the 5k imac at 1440p, can you guys tell me how the video quality is because it is not the native resolution. Im trying to find out if there is any blurriness or jagged edges as compared to native non retina 1440p. Thank you!

    I had the 2014 5k and I played DOTA, LOL, FFXIV and I never complained that the screen was blurry. I've since sold it and gone back to a PC because I wanted to play on max settings and without the constant fan maxing out on the imac.

    1440p is 1440p providing the display supports it.

    I use my 5k iMac to game in bootcamp at 1440p and games look amazing. I don't notice it is not native like I would on other monitors. I upgraded from a 2012 iMac with 680mx and also worried about this but there really is no need

    thanks for the replies!!! i was just worried because 1080p on my 1440p display looks very very blurry and low quality so i assumed that it would likewise on the 5k imac for 1440p

    Your current monitor must not support 1920x1080

    Clearly not if it can't display the resolution correctly. Thought that was kind of obvious.......

    Wow do you understand the difference between native and non native resolutions on a monitor?

    At non-scaled (by OS X) 1440, it should look as good or better as a standard 1440 display. This is because the 5K is 5120x2880, which is exactly double the resolution of 2560x1440. When forcing the display to scale to 1440, there's no odd pixel interpolation, so it would look exactly like a standard 1440.

    However, non-scaled 1080 (by OS X) will not look very good since that's not an even pixel interpolation. The display scaling looks just as bad as it would on a standard 1440 display.

    (this all assumes we're discussing display scaling resolutions... we're not talking about OS X's scaled resolutions which is an entirely different discussion)

    I get the impression you may not understand what's being discussed. Non-native resolutions generally result in a blurry/jagged display image.

    Well yes that doesn't take a rocket scientist. It's a completely subjective topic about what OP calls blurry and low quality. Is he meaning it just looks low resolution, or does he mean it doesn't display correctly. There's a big difference. 800x600 displays correctly but it's just very low resolution. But it isn't blurred at the slightest, everything just has jagged edges. Resolutions that display "very blurry" generally tend to be resolutions that the monitor cannot display correctly.

    When the first RiMac was new, I've red that when you play at 1440p on it, it was not as sharp as on a true 1440 screen, because it seems that when the panel is not used at its native resolution, the panel processed the signal and it is not as sharp: when 1440p is displayed, it seems that the panel does not simply take 4 pixels to display one, it apparently tries to "enhance" the image (upscaling?) so it is not as sharp as on a true 1440 panel.
    But I have not checked that...

    here no problem at all... in games if you lay something at 1440p on 5k imac it is the same image like the non retina 27"
    so stop worry

    There is nothing to worry about. 1440p is a factor of 2880p (5K). So, 4 perfect pixel 5k to display 1 pixel in 1440p. It will display the same sharpness.

    I am now play games in 1440P on my 4K TV. It's 84", so I can clearly see all the details. In theory, 1080 will be better because that fit the 4:1 ratio. In reality, 1440p works very well even in 4K. And the non-native resolution actually makes the edges a bit smoother, so AA become less important than in 1080p.

    After trying multiple different settings (from 1080 to 4K), I end up stay at 1440p very high settings, which gives me the best balance between performanc and picture quality.

    Thank you. This was a interesting read. The 5k display seems to be a great achievement

    No problem. My own place is renovating at the moment, this is the beast in my temp home. As you can see, the small monitor in the middle is the 27" ACD. That looks tiny :p

    No choice, there is the only place in this temp house to put the TV on safely.

    Anyway, I can put some 4K wallpaper on the TV to "pretend" a window. So I can have whatever scene I want ;)
