    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

    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...

    7 years later, is that PSU even still healthy? Caps don't last forever 😳😯 has the PSU occasionally been powered on routine to maintain it? Or has the PSU been in active duty the last 7 years? Or has it been collecting dust?

    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...

    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...

    How to scriptably uninstall patches for Windows 10?

    First: you can no longer use wusa.exe to uninstall patches silently since Windows 8/Server 2016, so this is out of the question. You. Just. Can't. Do. It! Thanks Microsoft (for ingeniously deciding that parameters /quiet and /kb:kb123456 are illegal to use together). Sometimes wusa.exe will be...

    Year of the Desktop VR? How many more iterations will it take before VR is flawless?

    I would like to have productive VR-AR hybrid. I have come to find that a 43" 4K monitor has the sweet spot, but the next step is VR-AR hybrid, but it has to be able to exceed the value of a 43" 4K monitor for productivity in usability, resolution, and sense.

    Lightest Live Linux OS that supports making Remote Desktop Protocol (RDP) connections?

    For "lightweight" I am expecting the OS to have a boot time of "lightning fast" from a USB 1.1 port with a feature set equal to a zero client (bare minimum requirements + straight-up RDP capability). Reality is likely different based on what is available, though.

    The 16GB of HBM2 on the Radeon VII Is Needed for Real World 4K Video Production

Professional cards won't provide any benefit or justification. EDIT: I did some more digging to find this...

    Difference between 4K 42" TVs vs 4K 42" Monitors?

    Did some research and I definitely agree, this is a big one. I didn't know that HDMI was limited to 24/30p @ 4K and handled half the bandwidth of DisplayPort. DisplayPort is clearly the winner, and the next revision of DisplayPort will dominate even more with 8Kp60 support and 32Gbps...
