"Which option is better for 1440p gaming: 1080p upscaled to 1440p or 4k downscaled to 1440p?"
Downscaling a 4K image to 1440p can result in a loss of image sharpness and clarity due to the reduction of pixels.
Upscaling a 1080p image to 1440p may also result in a loss of image quality due to the addition of extra pixels that may appear blurry or oversharpened.
The main difference between 1080p and 1440p is the resolution, with 1440p being a higher resolution than 1080p.
4K has an even higher resolution than 1440p, meaning that downscaling from 4K to 1440p may result in more noticeable image degradation.
Graphics cards, such as the GTX 1080, can handle 4K at high frame rates, but may struggle with ultra settings.
Some users report success with upscaling 1080p to 120fps for competitive gaming and around 80fps for other games.
1440p can be downscaled to 720p very naturally, but downscaling to 1080p looks weird due to the non-1:1 mapping of pixels.
Similarly, 4K can be downscaled to 1440p, but the image will be slightly fuzzy.
The difference between 1080p and 1440p is that the latter has just over 15 times the pixels, while 4K has 4 times the number of pixels as 1080p.
However, 4K monitors cannot reach nearly as high a refresh rate as 1080p and 1440p monitors, with the highest refresh rate on a 4K monitor being 165 Hz.
Running 1080p on a 1440p monitor results in a 76 jump in detail and processing power required due to the increased number of pixels.
A 1440p display has about 76 more pixels than a 1080p display, which translates to a 76 increase in detail and processing power required.
The cost difference between a 1080p and 1440p monitor is around $100 to $150, while a 4K monitor can cost up to $350.
Upscaling a 1080p image to 4K using Nvidia's software feature can result in improved image quality, but may not match the sharpness of a native 4K image.
A 1080p image upscaled to 1440p will have more pixels, resulting in a sharper and more detailed image.
Upscaling a 1080p image to 1440p can improve the appearance of the image due to the increase in pixel density, but may still result in a loss of image quality compared to a native 1440p image.
