    Lightroom slows down at 4K Monitor

    mhierse82

      I encountered a significant slow down in normal Lightroom work (zoom in/out, rotate, develop,...)  after switching from 1920x1080 hdmi to a 4K Monitor running at 3180x2160@60Hz Displayport 1.2. What can I Do to fix this issue? Anybody else who has this problem?

          Hello,

           

          this is common problem with LR. Speed depends on the number of displayed pixels (computation is done on the displayed photo pixels). More pixels - less speed. There is not much you can do. You can update your CPU to a faster one. But you increased the number of pixel by >3 - you won't be able to increase CPU speed by 3. Change graphic adapter does not work for LR.

           

          So we all (?) in this forum wait for more speed!

            Hi,

             

            Thank You for the fast response. I have an AMD 6core cpu at appr. 3,5 Ghz. So what would be the best upgrade option (power at value) from your experience?

             

            I also have a new nvidia quadro GPU for video editing - hope lightroom will use that in future releases

              Hello,

               

              there are a lot discussions about LR speed in this forum. Search for them, so you have lot of different meanings about this issue. My personal opinion is:

              • if you can wait, wait a few months. Adobe must fix this issus with LR6. And I expect LR6 betas in the next few month
              • rethink about your editing workflow. Do some adjustments as lens correction, upright, clarity / sharpening, extensive brush usage at last.
              • think about overclocking (in "turbo mode"). High CPU usage in LR is only for a short time. OC should not be a problem here. (Deactivte during video rendering)
              • By a cpu with the highest GHz speed in single core more. Less cores, more speed (The opposite is true for video rendering, but this can be done on GPU!)

                Hello,

                 

                you might have a look at this thread. Lightroom 5.6 Slooow!! They report about speed improvements with LR 5.4
