I decided to do another in-door workout today. The weather is nice out, but I think I need a few more days of recovery. I renewed my Zwift subscription today. The workout went well. I was doing intervals for the majority of the ride. Starting with a 5 minute warmup. The legs felt good. Lungs, ok, but slightly irritated from the cold. Everything else went well, with the exception of the display. For some reason, the TV screen goes black, on a random basis. It got worse towards the end of the ride. I tried swapping out cables and switching ports. Almost leads me to believe that the laptop is to blame. If not, then something else such as the video drivers, or the graphics settings on the Zwift app. Other notes, about 2500 riders today.
