4k Monitor: does it make sense?

Post by palimmo » Sun Aug 11, 2019 6:22 am

Hi,
I'm going to buy a new monitor (something between 27' and 31') soon.
It will be used mainly connected to my laptop to stream movies and do sometimes office stuffs. I am not a gamer or graphic editor.

a) Does it make sense to spend more and buy a 4k monitor over a 1080p? (budget: max. 250€)
Is the difference on a 27'-31' monitor watching full screen movies (ca. 2m away from the screen) noticeable?

b) Right now I do not think many stream services or tv channels provide a 4k resolution. Will it be in the near future?

c) My actual laptop probably doesn't even have enough resources to stream 4k. Am I wrong?

no point in using a 4K TV/Monitor if your videos are not 4K. do you have enough bandwidth to play a 4k video? https://www.youtube.com/watch?v=LXb3EKWsInQ <<< this is COSTA RICA IN 4K 60fps HDR (ULTRA HD) you'll need to change to 4k (2160p60) in the youtube controls

my ryzen3 and internet struggle with 4k on youtube. plust not all youtube is in 4k yet and most older videos will be transfered to 4k but it will not be trueHD

Dont do it. For the money you have to spent you will only be able to spent a 4K monitor with 30Hz instead of 60Hz. Of course they wont tell you about this troublesome fact in the store and neither on the shiny 4K websites. The troublesome difference between 60Hz or 30Hz is that the latter 30Hz will give you moving pictures that are constantly stuttering / not fluent. I have seen it and it is incredibly annoying. Many people complain about it, who bought a cheap 4K monitor.

Furthermore you will need a really powerful laptop and an expensive internet connection to run 4K smoothly. This means you gotta spent even more bucks than you were planning to.

And last but not least, when your monitor is the size of 27 to 31 inch I wouldnt bother at all. Wait 5 years. Everything will be 4K then and all the new average/cheap computers will probably be able to run it smoothly as well.

You gotta understand that the power of Linux is in making old hardware valuable and snappy and fast again. Linux does not support the newest hardware very well and you can get great beautiful 1080p pictures for practically no money with an average monitor and an old computer.

4K is gorgeous, I really love the looks. But dont fall into the cheap bargain trap and buy a 4K monitor that gives you non fluent 30 Hz pictures...

IMO given the limitation of human vision, 4K is marketing hype. To the human eyes, once the pixel get below a certain size, it all looks the same. I have a 15" laptop with 1920x1200 resolution and I find that to be difficult to use, much less 4K with even smaller pixels. That is why many O/S now have a scaling option to make things bigger for comfortable viewing. IMO refresh rate, viewing angle, black level is more important once pixel size get to a certain limit.

No, This is the silliest part of 4K video. You'd need an enormous screen even at 2M.

4K video is HEVC format whereas BluRays are AVC. HEVC is a mch better codec and that's why 4K looks sharper, not the resolution.

They wont be able to depict 4K resolution, but if you are asking if those monitors are ok for displaying HD, then yes they would do fine, because all monitors nowadays will play 1080p pictures perfectly.

At that average price range of 200 euro you will get a decent monitor. Dont expect greatness and dont expect many (future) connections to be present, nor expect a dead pixel guarantee etc, but my previous monitor was in that price range as well and it did fine for 10 years.

There are lots of great quality Hifi / Video test magazines in Germany. Even online you will be able to find great reviews of tv / monitor displays. I always check certain test sites before I buy a monitor to check online which monitor has won an award, 2 years previous, and then I buy it for a reduced price. Have fun choosing. I am curious to know which one you are going to buy :D

In my case 4k makes great sense because my eyes were quite fit with Apple retina devices long before I switch back to desktop with Linux distros. Well, if you just aims at video then probably you won't gain a much improved experience since 1080p videos are crystal clear if their encoding quality is greater than mainline H264. However, differences transcend human imagination for vectors by which I mean applications like reading or creating vector graphics or GAMING.

I have two self made 4k monitors using LG LM270WR5-SSA1 panel which is the same as the one in Dell UltraSharp U2718Q. They offer IPS panel with 10bit color HDR and generate gorgeous pictures at half the Dell price!
