PC OEM MSI addresses the PlayStation 5's 1440p woes with "console mode" scaling on supported monitors
MSI recently announced that it'll be rolling out a new "console mode" on a select number of monitors. This would enable these monitors to accept a 4K PlayStation 5 signal and downsample to their native resolution. The fix comes amid disappointment about the PlayStation 5 not having support for 1440p monitors. Sony's console outputs either 1080p or 4K. On regular 1440p displays, this means that the PlayStation 5 outputs a 1080p signal that's then upscaled, hurting image quality.
MSI's solution actually improves image quality on 1440p panels hooked up to PlayStation 5 consoles by applying a degree of supersampling. This is far from an ideal solution, though. "Console mode" only works on a handful of MSI monitors. Many of the listed console mode monitors feature a 21:9 aspect ratio and will likely output a pillarboxed image.
The only real, long-term solution here is for Sony to bring out a 1440p firmware update. The Xbox Series X already supports 1440p panels, so this would be a move towards cross-platform parity.
