Non native resolution

[matulley]

Was looking into buying the Asus ROG Swift then found out alot of AMD users are having alot of problems with it so now my attention went to the Asus PB278Q and realised that the 4k verson the PB287Q is nearly the same price.

 

Is there any problems id encounter running the 4k PB287Q at a lower res like 1440p for example. As id then have a nice 4k monitor for the future

 

Thanks

Doable but there is a look in quality

 

Check out reviews on TFT Central they normally review "interpolation" and how the monitor handles lower none native resolutions

1080p on a 4K screen (3840 x 2160) should appear just fine.
1440p might look a little weird on a 4K screen depending on the scaling method used.

The ratio's are all the same so would that help at all?

Well, if you have a 4k res montior and use it on 1080p, every 2x2 pixels on the monitor will represent one of the 1080p's resolution pixels. But when you're downscaling 2160p to 1440p you need to devide some pixels in (for example) 1/3 pixels, this obviously is not possible so the image will appear "fuzzy".

Unfortunately LCD panels have a fixed amount of pixels, they rely on scaling methods and interpolation when they have to use a non native resolution and make it fit in the area of their native resolution.

4K (3940 x 2160) is an exact multiple of 1080p (1920 x 1080), so it can show the image without any weird interpolation. 1440p isn't an exact multiple, so you could either show it natively but with black borders, or you will have to deal with weird interpolation and scaling methods that could make the image blurry or weird.

Hmmmm, really tied now, not sure what to get, the 1440p PB278Q or the 4k PB287Q

 

Using a 4790k with 2x sapphire R9 290's in crossfire. Benchmarks are all over the place for 4k, seen some saying 1 R9 290 can handle 4k no AA 40psish then im seeing other 290X CF at 40fps
