    Hi - anybody running a Vega 20 MBP with two LG 5K external displays? Does it run them smoothly?

    I’m currently using a 2017 13” MBP with one LG 5K and it definitely struggles, most noticeably when scrolling through photos in Canon’s DPP photography app. I’d like to add a second LG 5K for the real estate but I know I need to switch to a 15” for that - but I’d want to know it can drive them well.

    Thanks!

    I mentioned on another thread:

    "I had the same loaded 2016 MBP, but with 2 tera, and just upgraded to the same 2018, i9, 32MB, Vega 20, but with 2 Tera.
    I have 2 LG 5K's each connected to one side of the MBP.

    On the 2016 a couple of times a week, it would freeze when connected to the two monitors (latest LG firmware helped, but not fully resolved) - since I got the 2018 - no issues with the twin LGs.

    The 2018 is super-fast at everything..."

    So far, so good. Has been working very well with the 2 LG5K monitors

    Okay, thanks. Sigh, it’s going to be an expensive couple of weeks. :)

    Do you use them in HiDPI/retina mode I assume? i.e. effective area in terms of points is still 2560x1440 but things are sharper since they are rendered at 5120x2880?

    I have got a Vega 20 machine and in the next couple of years I am thinking to move from my current 2560x1440 27" to a 5120x2880 Retina 27" display. So I was wondering how is the frame rate and overall performance...

    I use the on the default for display - 2560x1440. I also tries the 3200 x 1800 - I don't use it for any gaming, but everything (including 4K videos) is sharp, smooth, and the Mac has not hanged even once (which my previous 2016 would do once every few days with the monitors connected).
