27"+ Simulated 4K (1080p) vs real 4K for desktop use (now GAMING) - Page 3

post #21 of 108
DSR only works as a gaming thing. The minimum of generating 3D rendered pixels for what is visible is not enough information to produce a smooth (jaggy-free, accurate) picture. Extra information that is boiled down into a lower resolution screen therefore produces some benefits.

2D elements are generally already optimized to fit a maximum of information into their intended display resolution, for example fonts being smoothed with subpixel rendering, bitmaps being downsampled from higher resolutions with techniques somewhat analagous to DSR. So DSR on your video card adds nothing useful on top of that, and isn't anywhere in the same realm as having more resolution to work with. While your windows may get tinier to open up more workspace, text becomes significantly garbled, so you may not be able to make effective use of such workspace.

Another issue with common 4K monitors viewed at hi-dpi (like 28") is the extra static clarity they bring is lost in frequent motion, such as in 3D games, on the generally poor response times, making it harder to distinguish vs. DSR. If you are staring at mostly static desktop content though, the higher DPI is far more apparent.

Personally I don't trust Korean monitors, but, a lot of people love them.


The common complaint I see with smaller 4k monitors are the pixel density is so large that text is very hard to read without scaling. Even on that 32" you're dealing with pretty tight ppi (137) for comfortable reading.

A dpi calculator.

For reference, a 27" 1440p has a dip of 110 and is considered comfortable to read for most while still being clear and sharp.

damn they got nice screens! Wish I knew it before I bought my tv set. 1k for 55", expedited free intl. shipping... I paid for my 60" philips 3k :/

DSR isn't the same as having the pixels. No matter what you set it to.

The biggest difference I noticed when gaming moving from 1080p to 1440p was distance objects being more detailed. Reason for this is there are more pixels to fill in that finer detail. By the time you get to true 4k everything is much more clear and detailed. It's impossible for a screen running DSR to truly capture that.

At 4k things like picture on the wall, cans of coke, smaller details on the models all become clearly visible. You can clearly see tattoos, art work on books and magazines laying around.


My friend and I were playing Dying Light the other day. He's on a 1440p 34" 21:9. I'm on a 43" 4k. I noticed that the enemy we were fighting guts were showing and visible. He thought the thing was just bloodied. DSR can't possibly capture that extra level of detail.


Here's an article about DSR.

http://www.pcgamer.com/nvidias-dynamic-super-resolution-is-downsampling-made-easy/


The basic idea of down sampling is more information is available so the image can be more completely filled in. Were in up-scaling less information is available so you end up with that block effect.

Yeah i kinda usel the upscaling term badly, i meant the fact to increase dpi or something.
I played quite a few older and newer games on PC and i gotta say DSR did what you descibed, i can for example recall the carpets and two-face/uncle sam posters being more defined with DSR 2X during the beginning of Batman Arkham City
This kind of thing: Warning: Spoiler! (Click to show)
Now the real question is again "how much of a difference", hence the need for testing and objectively feedbacking.

Also i find it strange that you noticed any substancial difference when playing as the gap is about 8dpi whereas 27" 1080p vs 1440p is 27dpi, maybe you were sitting closer or you have a better view than your friend lol

DPI adds clarity. The image will look sharper and more defined.

At 4k no matter the DPI you have much more information viewable. My screens DPI isn't as high, but, it's large and clear to see.

I'm planning on moving this 4k 43" tv to my bedroom, and going for a 40" 4k. Though I've gotten used to the size, the 40" dip is the same as a 27" 1440p.


*I mainly got this TV to test out 4k. I bought it at Walmart where there's a 90 day return window. Long story short I love the TV and so does my ol'lady. It's just not the best long term computer solution. Will be great in our bedroom though.

Yes. But, dpi isn't the same as resolution. He might have a clear image, but, not as much information being displayed.

Ok,

A 27" 1440p = 110 dpi

A 40" 4k = 110 dpi

Both screens should have about the same level of clarity. However, the 40" 4k has a higher resolution therefore is able to have a much more detailed picture on screen.

As said, dpi mostly affects the perceived image depth and smoothness (jaggies). You need to go have a look at those monitors somewhere since we can't tell how's your vision and preference regarding comfortable viewing distance.
