    42" 4k TVs as monitors!

    I'm using a 4k TV as a monitor, (Following a friend's example) and I recommend it highly! MacOS works well at 100 dpi or 200 dpi, but gets awkward between 120-180 dpi. So I worked out how big a 4k screen would be if it was 100 dpi. The result was 42", so I bought one! It took a couple of days...

    Esoteric Graphics Questions/Findings (another T221 thread)

    Hello all, This is kind of an obscure advice-needed/infodump post, though for me this is all just tinkering or proof-of-concept. I have a cMP 4,1->5,1 with an MVC-flashed 1080Ti as its GPU, as such it's still running 10.13.6 with nVidia's web drivers (this works fine.) Recently I've been...

    M1-based Macs, latest Big Sur, and Kodi capabilites as HTPC

    Hi :) I'm wondering if anyone is using an M1 Mac and Kodi for HTPC purposes? Or might test it for me ;) I know that Big Sur supports HDR output, but this might not translate to video content being put out via HDMI with the proper HDR metadata and so on. I also see that the first release of Big...

    MacBook Pro (13-inch, 2017) fan go full speed and becomes loud when connected to a 4k external monitor

    Hi. I bought a new 32" 4K LG Monitor and I really like it, except that my MacBook Pro fans go crazy when the monitor is connected and it gets really loud as if I am running a high-demanding app or something, even when I just have 3 tabs open in chrome, or playing a youtube video in 1080p. I was...

    4k60hz on 2012 iMac

    Hey everyone, I just bought a Samsung UR55 monitor, and I never actually checked if my iMac could run it (stupid, I know). To my knowledge, the GTX 680MX supports DisplayPort 1.2, which can do 4k60hz, but the GK104 chip is limited to 3/4 of the true transfer speed of DP 1.2 (which can still do...
