1440p 27" vs 1080p 24" looks basically the same.

[GerKNG]

my current Monitor since around 10 months is the LG GL850B.. basically "THE" 27" 1440p 144Hz Monitor.
my friend recently bought an Acer XF3 (or as it's sold with the name: "xf243y pbmiipx")
it's a 1080p 24" 165Hz IPS Monitor for around 60% less money than my GL850.

side by side (except of the actual space due to the resolution) the picture quality in games is basically the same.
textures are almost identical, overall sharpness and clarity is barely noticeable... (except aliasing in games with awful AA implementations like CoD Warzone)
and when actually playing a game i can not tell any difference except when i hold my face literally 10cm infront of the screen and cherry pick some minor differences.

after having two decent Panels side by side my opinion has changed. 1080p or 4K. 1440p feels like a 1080p replacement for 27" and above.

It's been known for a while that 27" is ideal for 1440p, while up to 24" is ideal for 1080p. 1080p should look less sharp on 27". I think I read somewhere that 4K makes sense above 32".

My 1440p dell monitor is just 23.8" and got 123dpi, so very sharp.

yep, I wish they made high end IPS panels at this size and rez, to my knowledge only TN exists and even then it doesn't exist anymore.

You are 90% correct - 1080p 23.8" high end IPS that came out within last 6 months or so, it a bit of a different beast than 1080p of the past. Not sure what they did, but I can also tell the difference. It's still not as sharp as 1440p, but it has improved somehow, which I know doesn't sound possible... but I understand exactly what you mean oddly enough. I really love my 1080p IPS 0.5 ms panel, it's really gorgeous in game and no FPS hits like the higher rez's.

this is my monitor. I highly recommend it. I also plan to have a dual monitor setup with a 1440p someday. I do expect text and such to be a little sharper. but not by much... in-game, when you have game settings maxed out - you are correct, its getting harder to tell. websites and text and game icons I can tell a little. but its not as bad as a 25" 1080p.

you mean this one?

 

[droopyRO]

It's a subjective thing.
At work i sit about an arms length from the monitors. At home i sit more than one meter from my 32" 1440p display. That is the ideal size and resolution for me. I also have a 32" 1080p display that is ok if you sit more than a meter away and you only do multimedia and gaming.
Eye sight is also a factor, i keep the text size to 125% for 1440p as that is most comfortable for reading for me. 27" 1440p is too small for me, i used to have a Dell and an Asus 27" 1440p at home that i kept at 125% display scaling. At work i have an Apple display and the text size is uncomfortable small in some applications i use.

For me, monitors are a try and buy thing, specs alone are not enough.

 

[Shou Miko]

My old 23,8inch was 1440p and my 27inch is 4K.

I feel 1080p is blurry at 23,8inch and more but 1440p is a sweet spot and 4K at 27inch can be small but I enjoy a big desktop and so on

 

[P4-630]

24" 1080p = 92dpi
27" 1440p = 108dpi

 

[Gmr_Chick]

My monitor is 1080p, 27" . 27" is my sweet spot. It's big enough to where I don't have to strain my eyes, but small enough to still fit on my desk, lol.

1440p 27'' is my personal heaven

Correct.

The calculation here is Pixels Per Inch, or PPI.

A 1080/24in model has 92 PPI or so
A 1440/27in has just over a hundred.

Pixels Per Inch PPI Calculator

PPI Calculator finds pixels per inch (PPI) and pixels per square inch (PPI^2). Calculate screen resolution and pixel density using width and height of display screen in pixels. Also find dot pitch and diagonal in pixels. Enter screen diagonal in inches or cm.

www.calculatorsoup.com

You can check any size/res here. Ppi relates to the ability of the human eye to discern detail and around 100 is suited for ergonomic viewing distance with mainstream diagonals/ office work use case while not being butt ugly.

Going higher in PPI will increase your tendency to 'crawl into your screen' as you work harder to distinguish detail.

The programs you run are also very important. A very common bussiness software used by many, many companies in the Nordic countries doesn't do scaling at all; it all becomes blurry.

I'm personally in the trend of horizontally increasing things aka ultrawide, Xiaomi and LG have come up with cheaper but still seemingly decent VA options there, high refresh rate. Wider than 27, not as power hungry as UHD. Best of both worlds IMO.

My two 27" monitors look the same for gaming picture quality ( LG 27GL83A-B & Dell - SE2717H 27") even though one is 1440p and one 1080p. Actual picture quality (real photos) is a different story. Comparing PPI is great in panels that are of relative quality otherwise I don't find it telling me much. From Tom's review of my Dell monitor;

"We’ve said time and time again that resolution does not matter nearly as much as motion quality, contrast, and color accuracy. When the gaming planets are aligned, the extra pixel density provided by a QHD or UHD screen just doesn’t have much additional impact."

 

[Splinterdog]

I definitely noticed a big difference when I moved up from a Samsung CF591 27" 1080p to an LG GK650F Ultra Gear 32" 1440p 144Hz.
There could be numerous factors at play, with no more tearing, I can't even see the pixels and gaming is ultra smooth. Of course, it may also be a case of favourable perception on my part, but the extra size certainly makes games much more immersive.

 

[las]

1440p on a 27" is by far better than 1080p at 24"

No comparison if you ask me. 1080p needs massive AA to look decent. 1440p does not. 80% more pixels. Way better image quality and much better for work outside of games too.

I could never live with a 1080p monitor today. If I _only_ played games? Maybe. Still not sure, 1080p sucks badly for browsing - you are scrolling all the time.

To add to the topic IMO I would rather play on 50" FullHD TV @ 1080p than on 50" 4K TV @ 1440p.
It's just the way 1080p is natively rendered pixel by pixel on FullHD panel looks better to me than 1440p blurred on 4k panel.

Depends on the TV I guess. My LG C9 OLED renders 1440p perfectly fine. Looks clearly better than 1080p (less jaggies)

For me, it depends on what's happening. Watching stuff: wide. Doing stuff: tall. I miss 4:3 for CAD, and they're also better for portrait mode.

 

[mclaren85]

I think clarity of the image could only be measured by "DPI" (pixel density)
here is how it can be calculated:

I'd side towards TVs for watching stuff, like at least 49 or so as long as you have a decently sized room. Netflix and such experiences are certainly better there.

The programs you run are also very important. A very common bussiness software used by many, many companies in the Nordic countries doesn't do scaling at all; it all becomes blurry.

Me using Visual Basic 5.0 apps that don't work at all if you have a touchscreen. And don't do scaling at all.

 

[mtcn77]

1440P isn't even -0.5 LOD(2x AA, %50VSR/DRS) improvement over FullHD.

 

[birdie]

Not in my experience.

I've upgraded just recently and the pixel density for a 27" QHD monitor is quite higher than for my previous FHD 24" panel.

In Windows I've enabled 125% scaling for UI, in Linux I had to either increase fonts, or increase scaling in my web browsers because everything became quite smaller.

My vision is not 20/20 though.

 

[mtcn77]

I went nuts over full screen antialiasing a while ago. It turned out that was pretty much planned obsolescence. If I were to develop it, I wouldn't base the resolution on "helper pixel" unfiltered image. The stupidest filters did ironically more to alleviate it.
If it was available, analytical filters on 2xRGSSAA final blend target would do best. However the analytical filter didn't target the final frame buffer, so the downscale filter didn't do its low-pass filtering like I wanted to.
If games used advanced filters like MadVR I would replicate it with something like a 25/150 double/quad super-xbr luma scaler, just something to upscale after staircase effect artifact filtering.
