Periodically I’m tempted by the ultra wide monitors on the market. If I buy one, it’ll be the 29” LG but my question is can the new pi 3b+ do 60 Hz at 2560x1080?

  • The Pi 3B+ apparently has HDMI 1.4, which I think means it will support it, without being able to check though from the looks 4K (video) works. however it still has a similar GPU to previous versions so I'm not sure video etc will be able to run a native or higher resolution AND frequency.

  • No Raspberry Pi will play encoded video at reasonable framerates for resolutions greater than 1080i. I can't prove this for unencoded video, but the sheer bitrate should overwhelm any Pi easily, since I/O capacity will, is and always has been very limited on this platform.

    Resolution of 2560x1440 is common. Did you really mean 2560x1080? Commented Jun 7, 2018 at 20:55

All Pi models have the same Video Core, so the Pi3B+ is no different to earlier models in this respect.

There are some limitations in the modes which can be supported due to the pixel clock limit. See https://elinux.org/RPiconfig#Video

I suspect you are out of luck; even though the rate may be supported there seems to be no wide screen mode - it is possible to create custom modes. I have never seen a screen with a 64:27 ratio!

  • 2560x1080@50Hz is within the pixel clock limit.

You can try this. with support for 2560x1080 resolution on LG25UM65 display. 2560x1080

    "You can try this" is the only part of this answer I could parse. Commented Nov 15, 2018 at 8:55

    I think you should add the config.txt to your answer and explain what it does. And remove the random, irrelevant values
