    Duplicating primary screen of iMac but extending on USB-to-HDMI adapters

    We have a 27" iMac with three additional outputs (1x Mini-DP, 2x USB-to-HDMI) all extended. We use this with ProPresenter 7. Is there any way to mirror the primary screen (the one built in to the iMac) to a third USB-to-HDMI device but continue extending on the three existing outputs?

    Troubleshooting TFTP/PXE with WDS VM and MoFi Network MOFI4500-4GXeLTE-V3 OpenWrt router

    Problem is solved, see my post right after the one you quoted. TLDR; dhcp-ignore option was set for clients presenting themselves as PXEClient. And, the dhcp-option, dhcp-boot, and dhcp-range settings needed to be set in /etc/dnsmasq.conf instead of through UCI via SSH.

    Troubleshooting TFTP/PXE with WDS VM and MoFi Network MOFI4500-4GXeLTE-V3 OpenWrt router

    Looks like I got it working! I removed any entries I had added with these commands: uci del dhcp.lan.dhcp_option uci del dhcp.lan.dhcp_range uci del dhcp.lan.dhcp_boot uci commit If you are using factory default of a MoFi4500 you do not have to execute the above. It was executed via SSH using...

    Troubleshooting TFTP/PXE with WDS VM and MoFi Network MOFI4500-4GXeLTE-V3 OpenWrt router

    Yes. In fact, with VMware Workstation, I do not have the ability to decide between those like you can with ESXi.

    Troubleshooting TFTP/PXE with WDS VM and MoFi Network MOFI4500-4GXeLTE-V3 OpenWrt router

    This posting is basically the same thing as Troubleshooting TFTP/PXE with WDS VM and Ubiquiti Dream Machine but using a MoFi Network MOFI4500-4GXeLTE-V3 OpenWrt router instead of a Ubiquiti Dream Machine. Same exact WDS VM, so nothing has changed on the VM itself and we know that WDS and Windows...

    CPU fatigue: myth or real?

    As there is not a single article on the internet on this, I thought I would start a thread to see if others have been making similar observations. I have a Lenovo ThinkPad X220 with an i5 CPU. This laptop is at least 10 years old if not somewhere within the 15 year ballpark. When I first got...

    Troubleshooting TFTP/PXE with WDS VM and Ubiquiti Dream Machine

    You know what, I am not sure what went wrong where, but I believe from the machines I was testing the tftp command the root cause was Windows Firewall. By default, I guess you cannot use a TFP Client to get a file from WDS. I wager the reason is that the communication with WDS is actually...

    Troubleshooting TFTP/PXE with WDS VM and Ubiquiti Dream Machine

    UDM is the only DHCP server. Server is standalone. I used an elevated administrative Command Prompt when performing the TFTP test. I am using Microsoft's TFTP Client (https://www.thewindowsclub.com/enable-tftp-windows-10).

    Troubleshooting TFTP/PXE with WDS VM and Ubiquiti Dream Machine

    Howdy! I have a VM at 172.16.32.4 named CON-MDT running Windows Deployment Services. If I execute the following command on CON-MDT, it succeeds: If I execute the same command on a different machine (such as my laptop or Intel NUC) it appears to do nothing for a while and then presents a...

    How to scriptably uninstall patches for Windows 10?

    Think in terms of 1000-10000 or more endpoints, and the latest CU or other patch breaks a critical line of business application resulting in 100% work stoppage for most workers. It takes time for vendors to patch their software as well as for Microsoft to fix their bugs. This happens more often...
