Nor it's supported by standard. |

I swear I'd tested this before - perhaps it was 4:4:4 on my old GTX 1060 or I was fooling myself somehow. That said, I genuinely cannot see the difference on ordinary desktop content - perhaps there are some use cases where 4:4:4 is critical, but it's already the case for me at least that 4K luma is beyond my eye's apparent visual sensitivity (in other words, I cannot distinguish the individual pixels in a checkerboard pattern unless I'm closer than 2 foot to the display). --- End quote --- I find it really hard to tell when the video isn't 4:4:4 except for small coloured text. Trying to edit with an editor that uses coloured highlighting is terrible with anything but 4:4:4. Most other things are just fine. There is a reason why we use colour sub-sampling. It plays to the strengths and weaknesses of our eyes, and works great most of the time. |

Dellaminating? What a quality crap, never seen this, ever! A 43" monitor will be like looking at a giant poster from 10". I bought a HDR 165Hz QHD 27" Lenovo g27q-20 in 2020 ($299), definitely getting into the "too large" area, I often struggle to find the mouse cursor, but the higher DPI is great, specially when splitting windows, but yeah, just at the limit of the visual field. My advice is to get QHD under 32", 4K will be too much DPI, and Windows scaling is crap, avoid using it at all costs. I know because I installed a FHD panel into my ex laptop, when she was doing the engineering 10yr ago, 1366x768 was a no-no for CAD and 3D design. Things were extremely small, 7pt text, but no problem, let's enable 125 (Or 150%) scaling! Now everything looked like I had breathed all over the screen! :palm: Now this this is the 27: |

--- Quote ---IMO 43" is too big for a PC monitor which for best eye strain should be no further than 4 foot from your keyboard. 32" is about the maximum you want to go. --- End quote --- Absolutely wrong :) I tried a 32" and despite having Windows scale at 115% (or whatever they do) it was still hard to read. And you lose pixels in the scaling. I gave it to my missus, mainly because nothing bigger would fit under the shelf where she has her monitor. My 43" is the same pixel pitch as my old 1900x1600 Dell monitors, so I can conceivably extend the screen without the cursor jumping around as it transitions. But my main delight is that I can read the bloody text without any scaling. Every pixel is a useful one. I sit just over an arm's length away - just measured at 32". It is fine and far more immersive than a tiny 32" screen would be for, er, immersive games and stuff. |

On text on 2560x1440 27-32 inchers it's very noticeable, on 28" 4k, not so much. On video it video it will be very hard to notice except something high contrast like text is displayed. Chroma subsampling works in part because human eye has lower color resolution than brightness resolution, not to say brain hides imperfections and often sees what it wants to see, rather than actual image. |
