    Horizon View 7.9 4K Monitor Poor Performance

      Hi Everyone,

      We are currently testing a new horizon view deployment and can not get good performance with single 4k monitors. Youtube playback is horrible and general VM performance is laggy on anything above a 1080P panel. We have run the optimization tool and are currently using Blast Extreme. I have tried pretty much every combination of settings for the Horizon client as well as changing GPO settings for the Blast Protocol. We have also tried PcoIP and received similar results. We also submitted a case with VMware and had an engineer verify our setup and he stated this was normal behavior when using 4K panels. At this point I am thinking we are limited by CPU clock speed but I wanted to see if anyone had any ideas. We also tried using vGPU and grid with a Tesla T4 card and still got very poor performance. I have listed out out cluster specs along with the VM specs we are using for Horizon View. Any ideas would be greatly appreciated.
