Monitor manufacturers may be putting 4K UHD (3840 × 2160) panels in some 1440p QHD (2560 × 1440) monitors. This can cause blurriness since one pixel would be mapped onto one and a half pixels:

Citing sources close to panel manufacturers, German website Prad.de writes that the costs of producing a 27-inch 4K 3840 x 2160 panel is often lower, or at least the same price as, creating a 27-inch 2560 x 1440 QHD panel. As such, some companies have reportedly been producing monitors that use 4K panels despite being advertised as 1440p. This is said to happen often when panel supplies are low, or monitor demand is high.

[...] Prad.de included a simulated monitor test image in its report (below). It shows native 1440p on the top and 1440p scaled to 4K on the bottom.

    Sort of like back in the day when a VCR vendor sold different tier devices with different sets of bells and whistles, but it turned out that they all used the same motherboard and it was artificial crippling of features that was the only difference between devices (and some external cosmetic changes).

    Slightly different though, because you got the features that $version was advertised at, regardless of whether the box could do more or less.
    In this case, People Who Know* buy LCDs at a specific native resolution, for visual comfort, yet they don't get what they paid for.

    *: People Who Know are a tiny subset of the market, often safely ignored.

    Absolutely - I suspect that was pretty much all vendors. I know Panasonic hid a microswitch for NTSC/PAL selection on the VCR that I had. I never needed NTSC, as I like my colours to be repeatable, so I never bothered pulling it out through the suspiciously blank bit of the front panel in front of it. It would have been a #50 upgrade had I wanted that feature ab initio. #50 for one sprung bit of plastic - ahhh, that's the power of market forces and the mythical "complete information".
