27"+ Simulated 4K (1080p) vs real 4K for desktop use (now GAMING)

post #1 of 108
Thread Starter 
Has anyone ever tried comparing the desktop experiences these 2 case scenarios produce ? I'm talking both about 'screen space' and clarity:

-27" 1080p screen with resolution bumped at 4k with DSR or VSR or any other upsampling thingie (150% scaling)
-27"ish 4k screen with native 4k resolution (scaling to match the scenario above)

also they should both include 'optimal' cleartype settings.



side note: is there a way to 'simulate a PPI/DPI comparison using only one (1080p ? pls) screen ?

Native will have A LOT more clarity. Upscaled 1080p can look good if you've got nothing to compare it to.

can someone post a pic or something, and what about functionnality ?

edit, i tested with a 4k pic and did a comparison between the cybercafe 1280x1024 19" (86dpi) and my S4 (441dpi) : yeah, the pixel concentration kinda helps maybe a bit but it's like 5X more (and with head pretty close), also keep in mind there is the contrast/panel type factor.

Here we're talking about 86dpi vs 163 at about (dunno exactly) 80cm-1m, is it really noticeable ?

Images do not accurately capture the differences, it's something you will have to see first hand. To put it bluntly, though, 1920 x 1080 made to run 2560 x 1440 looks extremely blurry and undefined compared to true 2560 x 1440 on a monitor of similar size. I have experimented with this on many occasions; there are reasons people don't openly recommend running a 1920 x 1080 model at 2560 x 1440 for enhanced desktop productivity. Key amongst those is the fact it is completely impractical due to the poor image quality.

Yeah i tried the '1440p' DSR equivalent 2715x1527 and i agree that the thing was ugly as heck, but when i used 4k, the unnatural blurrines was gone but everything was a tad small lol. More testing pls ?

also look up at my edit

edit: oh yeah also, can Amoled (my s4) screens realisticly depice the difference between TN and IPS ?

Don't get 4k! It's bs, worse than 5k drives vs ssd. Adds absolutely nothing.
biggrin.gif

just bored, sorry.
Upscale is meh. Didn't see noticeable difference except tiny tiny desktop icons. Desktop/browsing pretty much anything outside game/movie is terrible with upscale.
Don't see any point in 4k anyway, games don't look better to me and everything else is simply too small. Tried with one of those fancy dell 27" 4k screens.
IMO of course. Have tried it only on 60".

Nono, 'DSRed' UHD looks absolutely nothing like as crisp as the real thing. I found it completely unreadable, whereas the actual resolution is not. smile.gif

The blurriness is caused by some scaling issue (usually a hardware scaler). If you don't have to use a scaler, the picture should come out without the blurriness. You can do this with evenly dividable resolutions. For example, 4k has 4 times the pixels as 1080p. 5120x2880 would look really good on a 1440p screen but 5129x2887 would probably look more blurry.

As far as s4 screen and ips vs tn, are you talking about color replication or viewing angles? The screen will see the viewing angle difference for sure, but might underplay the color accuracy because of how over-saturated samsung phone displays are.

I don't care about viewing angles, it's the 'color richness' brough by other-than-tn-techs that i want to know more about.
Aside from the calibration, is the color 'depth' similar to ips or something ?
I have different color profiles than vary according to saturation, do you know one that would be the most accurate ?

I've got a 43" 4k tv here.

Each of those windows are about the size of a 22" - 23" 1080p screen.



How I have this opened on my desktop right now,




No way you'd be able to productively use the extra res of 4k with only a 27" screen. 40" + is going to be too large and really best for gaming. Maybe one of those 32" 4k would be a better mix for the two. Though Text might still be kind of small without scaling at 32".
