Computer Configuration

We have a few suggestions regarding how to configure Windows installations for experimental SLM usage.

Set “Screen Sleep” to “Never”

Although SLMs often exist as virtual displays, the action of “Screen Sleep” on Windows machines can interfere with these displays. In some cases, the SLM becomes unresponsive or stuck in periods surrounding a sleep event on the physical display(s). We suggest turning screen sleep off. If energy conservation is desired, consider turning the physical display(s) off manually.

Disable “Windows Aero Peek”

Upon hovering over a program in the taskbar, Windows Aero Peek hides all other windows to make finding this program easier. However, Aero Peek can also hide the window being used to project data onto the SLM in the virtual display, causing most power to return to the zeroth order, and in some cases burning holes through devices (this occurred several times before we realized what was happening). We suggest disabling Aero Peek.

Disable “Windows Update”

Windows Updates are important to ensure security and stability. However, on an experimental setup, these (surprise) updates can wreck havoc. We suggest disabling Windows Update and scheduling a periodic external reminder to install new updates manually.

Building an SLM Setup

There are a variety of ways to configure an SLM in a beamline, each with advantages and disadvantages. In addition, there are known “best practices” to consider when aligning. We’re in the progress of writing a full guide; however, in the interim, the alignment tutorial here should get you started!
