maybe you're way ahead of me here, but just to make sure, do you know what an appletv is? it's just a small box, maybe 4"x4"x2". it's a computer. what you'd need is an appletv 4k. it's $179. i think it's kind of badly named. you'd need to hook it up to a monitor of some sort. TV set (which is what it's designed for) or a computer monitor. i've got, i think, 3 of these in current use with zwift loaded on them, and i'm getting one more today. it's by far the cheapest, easiest way to run zwift on a decent sized screen.

zwift, like any app or game, will run on whatever operating systems the designers choose. zwift runs in iOS, OSX, windows and android. so, it'll work on almost any handheld device, tablet, or computer, except a kindle. plus, zwift will run on "appletv OS", which is great, because you really don't want to ride with zwift using a laptop or tablet if you don't have to. what you want is the biggest TV screen you can get.

now, the appletv 4k is also badly named because it's not really ultra 4k. i've got a pretty good gaming rig, a windows, and THAT is ultra 4k. you don't get quite the depth perception and the colors on an appletv that you get with a gaming computer. but that appletv 4k runs zwift pretty nicely.

what you need to get a pretty nice pain cave set up going is an appletv 4k, a repurposed tv or monitor, an hdmi cable and if you buy one i'd err on the side of a couple of feet longer than you think you'd need, and you're going to have to prop up that TV on something. rule of thumb is, if it's for running you'll want it high, so you can see over your treadmill. if it's for cycling you'll want it lower, with the bottom of the TV not more than about 20" off the ground, and you'll need to tilt that TV so that it's angled up, so that you're looking square at it when you're riding. if you buy a TV stand for this, make sure it's got that tilt capacity.

then, you have to have a smart trainer if you want to get the full benefit. that's by far the largest expense, because if you buy it new these will start at about $750 or $800. and a bike.

If you have chromecast or a smart TV you could cast from a phone or a laptop.

I was doing that for awhile then gave up and bought the apple TV (only use it for zwift). I like the convenience of it always being ready to go.

A 2 - part question.

My Tacx Bushido under-reports wattage. Does that mean I am going slower, relative to my peers on Zwift and thus, make racing an exercise in futility?

Is there a remedy for this?

(I tested my Zwift wattage against my CT wattage for a very similar effort. Over 30 min. CT = 190 watts for 120 HR. Zwift 142 watts for 118 HR).

As a third measure, on my Powertap, my wattage/hr numbers are quite close to the CT.

Thnx.

Gee, this is kinda like going to confession, let me start by saying forgive me Dan for I have......

Reasons for me not using my Computrainer for Zwift.

• Just paid 800 for the Bushido, need to get my money's worth out of this thing.
• Marital harmony, I use the CT whilst my wife is on Zwift.
• Ignorance and sloth (Cardinal sins?) - FTDI USB to stereo adapter. I know about it, but am reluctant to use it. My CT computer runs Windows Vista. My Zwift is run on my Samsung phone. I suspect there would be some sort of compatibility headaches. Right now both work. A bird in the hand... even if that bird has a mangled wing, it can still sorta fly well enough.

I might have already asked, but is there a reason you can't use your PT hub as the power source on Zwift? Then Zwift will be getting accurate numbers, the Bushido will just be following along to the terrain / resistance targets.

You can use PT Hub or any other power meter as power source on Zwift

Most of the top racers use an external power meter as power source as they are more accurate and respond faster than the PM in the trainer. Most also record their trainer power using Garmin or Wahoo etc in case they are asked to provide evidence.... but this is only relevant in specific races where they stipulate use a of a secondary set of power data

Can you really chromecast from a phone? that would be great if I could, lots of times I don't really care about graphics quality and just want the workout up on the screen (I rarely use the companion app in-game). It can be a bit of a pain to connect the laptop to the HDMI, change the input, etc etc...

Yes, you can. Works well enough in my experience. Will be very battery intensive, so have a charger.

You should have a "Screencast" icon when you swipe down to access your quick settings panel (I'm assuming you have an android phone).

If the screencast option isn't there tap the pencil icon in the lower left corner of the quicksetting panel and you should be able to add it.

Sorry, I suppose I should clarify, this method isn't like your typical casting (where the app has the chormecast button baked in). You are literally just casting/mirroring the phone screen to the chromecast.

I use this as well to give live video for position adjustment on the bike (turn video camera on and mirror/cast).

If I swipe down from the upper right corner to the bottom left corner on my iPhone, there is an icon for "Screen Mirroring". That is how I cast to my tv. Do you not have that icon? This is on an iPhone X.
