The 3840 x 2160 ‘4K’ UHD resolution requires considerable graphical grunt to run on demanding applications, such as some games. Users may therefore consider running a lower resolution such as 1920 x 1080 – and indeed if they are connected to a modern games console, this sort of lower resolution will be all they can use. If you connect the monitor up to a PC via DP 1.2, the interpolation (scaling) process is handled exclusively by the GPU. There is significant softening to the image compared to running the resolution natively, whether you select 1920 x 1080 (Full HD), 2560 x 1440 (WQHD) or something else. Whilst gaming, it looks as if you’re looking at the game world through a soft-focus lens.

If you’re connected using HDMI, either to a PC or games console, the monitor does have scaling features and will be able to use its own interpolation processing to handle non-native resolutions. As a PC user you should ensure that the monitor rather than GPU is handling this. If you’re using an Nvidia GPU (more likely with this monitor) you should open the Nvidia Control Panel and navigate to ‘Display – Adjust desktop size and position’. Ensure ‘No Scaling’ is selected and ‘Perform scaling on:’ is set to ‘Display’ as shown below. AMD GPU users shouldn’t need to change anything as the drivers are set up so that the monitor will handle interpolation, where possible, in games.


  唯一解决方法就是用hdmi连接，然后不用gpu来放大。用显示器本身的放大，这样只要是整数放大的分辨率，应该都不会糊了。用dp链接是无效的，dvi不知道

喷了，本来就可以设GPU放大还是显示器放大，显示器放大会好点，但是一般显示器处理rgb和ycbcr信号方式不一样，这是图像模式还是电脑模式一样，你可以试试

喷毛，dp链接。 在驱动改完全没有用，要hdmi才有用。dp你如何选，结果都是gpu放大，那个dvi我就不知道了。

用hdmi的话，pc那个降分辨率的效果和ps4是一样的。

不是点对点肯定糊啊

有意思，受启发，回头试试

这也许是HDMI收费的原因之一

dp原理和hdmi不一样，不是显卡做tdms，可能这样没法显示器缩放。gpu缩放其实加点味精就好
