    any observable difference between 1080 and 4k?


    Thinking if I should get a 4K monitor for home use.
    Yes, I like watching videos, but I don't know if
    4k will give an observable difference from 1080 ?

    I understand there must be difference, but is the difference significant ?

    For example, I don't notice any serious difference between 720p and 1080p videos with my 1080 screen

    Night and day. It depends on how good your eyesight is, how far you are from the screen.

    Visit a wallmart, target, best buy or store that sells televisions or computers.
    View side by side:
    High definition: 720p
    Full high definition 1080p
    Ultra high definition 4k


    In order to see the differences the video that is played needs to be 4k.
    A video that is made in 720 p looks about the same using a display that is 1080p or 4k.

    Going from SD to FHD was pretty big, but going from FHD to UHD are more in the fine details in my opinion. Less jagged edges and more refined textures at a distance. There's absolutely a difference, but it's not like SD to HD where some objects or icons were almost impossible to read or see.

    I remember playing TES: Oblivion in 576i back in 06, and I remember fondly not being able to see the map markers correctly. Then I tried it in 1080p years after and it was night and day. That same effect won't happen to the same degree going from HD to UHD, particularly if the things you're trying to use isn't made with 4K in mind. It's a bit of a waste if you're going to watch regular HD videos on a 4K monitor, or try to play games in 4K and the PC cannot keep up with the increased frametimes.

    If you're not going to use the 4k native resolution, certain apps can actually create an awful blur effect depending on the monitor's scaler and pixel value. Seems to be more of an issue on quad resolutions from my experience. I guess what I'm writing is that yes, there's a noticable difference, but also make sure everything is correctly set and supported for it. This is just my opinion on the matter anyway. Best way to be certain is to compare with your own eyes.

    You won't see a difference unless the source video was shot in the higher 4k mode. There isn't much of that yet, is there? The only places I've seen it is in the stores ... where they're trying to sell 4k TVs. At home I don't have any 4k channels available. None.

    Let's say you have two screens, same physical size, side by side. Left screen is 1080; right screen is 4K.

    You play a 1080 video on both. It fills the left screen, but only takes up 1/4 of the right screen.

    Do you really want to see videos 1/4 of their current size?

    A 4k tv is still going to play the whole video size. The resolution of the display has zero to do with how much of the video is displayed on the whole screen.

    I didn't say HOW MUCH of the video was displayed on the screen. I said 1/4 of the SIZE, not 1/4 of the VIDEO.

    And yeah, I know you can resize the video window but with the native size being 1/4 of the size you would see on a 1080p screen, I would think you would get a fuzzy image resizing the window to 4 times its size to fill the screen. And, if that is the case, then there is little value in having a 4K screen just to watch videos.

    You don't list your video card in your specs but if you have a supported AMD or Nvidia card you could enable VSR or DSR,

    What Is Virtual Super Resolution and How Does It Work?


    How to enable Dynamic Super Resolution in games. | NVIDIA.

    then go into your Windows display settings and set it 3840x2160, and get an idea of how it looks.
