Care to share some examples for the people who don’t share your opinion?

The biggest thing keeping me from using Linux for my desktop pc right now is lack of HDR support. Apart from that the whole display servers world is just not working well. Some things still don't support Wayland, you can't share screen easily, X has it's own issues etc. HiDPI is still problematic with both; you get weird scaling issues with apps and and the occasional humongous mouse cursor. Using multiple displays with different DPIs you again get scaling issues. Setting up multiple displays still requires fiddling with xrandr, xinerama etc. Just let me know if you need more examples. I tried to fully switch to Linux many times spending lots of time + money (bought one of the "recommended" devices).

  Multiple displays have worked out of the box for me for over a decade. Nothing fancy here, just X11 with the plain jane MATE desktop (and Gnome 2 before that.)

    Multiple displays works well if both displays have the same or similar dpis. When they are different like one is hidpi and the other one is not, you get scaling issues.

  > The biggest thing keeping me from using Linux for my desktop pc right now is lack of HDR support. HDR is just a marketing term for software that increases the colour and black saturation of content beyond the actual input. For photography that means more saturation than what you see in real life, for video that means tweaking it after you receive the signal. An OS can't "support" or not support HDR; if a video has HDR and your display has the dynamic range then you'll see it in "HDR". Unless you actually want your OS to post-process everything on the screen to have marginally higher contrast than normal? https://support.microsoft.com/en-us/windows/what-is-hdr-in-windows-11-f5fbf5cb-149d-4a0d-8be1-9ed78c68d3b4 https://support.microsoft.com/en-us/windows/what-is-hdr-in-w... https://www.pcworld.com/article/546269/auto-hdr-deep-dive-how-and-why-to-use-windows-11s-eye-catching-game-feature.html https://www.pcworld.com/article/546269/auto-hdr-deep-dive-ho... > Setting up multiple displays still requires fiddling with xrandr, xinerama etc. Dunno what you're doing but you can literally just plug in another display and it'll work... And per-monitor scaling works on Ubuntu/Gnome.

    > HDR is just a marketing term for software that increases the colour and black saturation of content beyond the actual input. For photography that means more saturation than what you see in real life, for video that means tweaking it after you receive the signal. Not even remotely correct. It is definitely not a marketing term. HDR is set of specifications and formats for capturing, storing and displaying visual data with a higher than "Standard" dynamic range. It basically carries more data and it requires proper color management. It has to be supported by relevant drivers and the display server. Right now there is no way to view HDR content (video, photos or games) under Linux. If you are interested; there is some effort going on to enable this but it will probably take a couple more years. https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/14 https://gitlab.freedesktop.org/wayland/wayland-protocols/-/m... https://gitlab.freedesktop.org/pq/color-and-hdr https://gitlab.freedesktop.org/pq/color-and-hdr

"HDR" is just metadata to pass along to the device to tell it how to optimally adjust the colours (or not adjust them). It's main use seems to be so that HDR displays can oversaturate "SDR" content in HDR mode. > carries more data Not really. The metadata isn't more colours or something, it just passes info to the device about certain aspects of the video. HDR content will be HDR if the display has enough range regardless of whether or not the OS has HDR "mode". It's more about adjusting all the other content. Dunno if you ever had a plasma TV back in the day but they could display way more contrast than LCDs of the day so you could adjust the settings to change the way all content looks. HDR metadata is basically that, but on a per-video basis. Useful enough but not some game changer... Which is why there's tons of articles about what HDR does and doesn't do. Edit - where HDR really is great is photography... You take multiple photos of the same scene with different ISO and shutter settings then stitch them together for more colours than would otherwise be captured. But a screen can either display colours or it can't.
