1 Screen Setup

A basic 1-screen setup consists of

   1. A 4k Smart TV between 43" and 75";

   2. A computer that can output video at 4k;

   3. A mouse and keyboard;

Important

For the various ways you can configure the screen upscaling and displayed text size independently for optimal readability, see the Operating System page. 4k smart TVs are easy enough to find nowadays. Many retailers, including computer stores, carry them.

Most recent computers have at least one HDMI or DP (DisplayPort) connector that can be connected to the TV. Most Smart TVs still don't offer DP functionality, so you may have to buy a DisplayPort to HDMI adapter. Something like this , $27 + taxes*.

Most such adapters don't support full 4k functionality, so make sure the one you get does (it should say 4k Ultra HD on the box), like the one shown..

The choice of mouse and keyboard is pretty simple - pick something you like. I'd recommend a wireless mouse/keyboard combo - it only takes up one USB port on your computer for the wireless receiver, instead of one port each for a wired keyboard and mouse, and there's less clutter on your work area.

You can use the legs that come with the Smart TV, but they're a real problem in several ways:

   1. They aren't the greatest for a work table or desk because they're easy to fall off the back edge;

   2. They raise the TV several inches above the work surface;

   3. They're ugly (hopefully you're going to be up close and personal with them for a LONG time).

All smart TVs sold today conform to the VESA Flat Display Mounting Interface, which can be used by table mounts, as well as wall mounts and display carts.

Simply put, it specifies the 4-bolt patterns that VESA conforming devices such as Smart TVs need to follow, so you know your stand will work with your TV.

Table mounts allow you to place the bottom of the display within an inch or so of your work surface; display carts allow you to place your display supports behind the work surface, and extending over the work surface, for maximum flexibility.

The Brateck Video Cart shown at right can be modified to hold a second 50" screen above the first when space is an issue, with a bit of ingenuity and some muffler clamps, a spare VESA mount, and some steel shelving channels.

It is much sturdier than carts that sell online for a few bucks less. There are 4 of them supporting 6 screens in the picture of my personal Work From Home setup.
