Integer Scaling - PS5 and 4K Spectrum

Hello all! Apologies if this isn’t the correct place to post this.

I will give a little background info for the question. I am looking to purchase a PS5 upon release and then the 4K spectrum. I play a lot fast-paced shooters (often warzone), so if I had an option between 4K 60fps and 1080 120fps on the PS5, I would choose the latter.

If I were to set the PS5’s output to 1080p - does anyone know if this will be integer scaled to 4K so that I can take advantage of the higher refresh rate and an integer scaled image?

I have heard that new GPUs are able to output 1080p signals and upscale them to 4K using integer scaling - which reduces blurriness when compared to other scaling techniques. I am not sure if this technology is restricted to gpus or if specific monitors themselves are able to do this (such as the spectrum).

Tldr: can the ps5 up-scale 1080p to 4k using integer scaling with the spectrum 4K.

Cheers :slight_smile:


HI, @Matt_Lawd! Welcome to our community, and thank you for your interest in Spectrum! :smiling_face_with_three_hearts:

All Spectrum models will support pixel-perfect integer-ratio upscaling. The exact supported resolution and refresh rate are being explored as firmware development moves forward; we will share more information once this is confirmed.

We will test Spectrum’s compatibility with PS5 and other consoles; if Spectrum turns out to support integer upscaling at 1080p@120Hz, it should comply with your use case.


Thank you very much for your reply!

I have another quick question - is it likely that the 1440p spectrum would suffer from blurriness when upscaling from 1080p to 1440p since no integer scaling is available, as is the case with most/all displays (I think)?


You’re welcome! I agree with you that since 1080p to 1440p is not an integer, it may not look good. However, in Spectrum’s case, integer-ratio upscaling resolutions supported by 1440p models will be determined at a later point.


This is exactly why I upgraded to the 4K Spectrum, concerns about 1080p and 4K video not holding up well on a 1440p display. The 1440p is optimal for people who are mostly just gaming tho and not really using their monitors to watch much video content.


Specifically if you only intended to use this monitor with a PS5, the 4K monitor (model 3) is the best selection to make. You will see no benefit from the higher refresh rate on the 2K (model 2) so you might as well benefit from the improved visuals.
