Product: Linux Commands: airodump-ng, iw Overview I do not like to use the airmon-ng command to change the WiFi device name to follow its original device name, which it is hard for me to remember, e.g. device name wlp0s12u1. So in this post, I will use "iw" utility (previously called iwlist, iwconfig) that bundled with Fedora 41, or RedHat RHEL 9, to configure the WiFi adapter in monitor mode with my preferred device name.  The benefits are: I can define my own device name, e.g. wlan0mon I can use pre-defined device name in script "iw" utility offers more information in the WiFi network adapter as well as LAN NIC USB device detection is more accurate It can shows device name of my USB WiFi dongle without additional typing It can creates additional logical device that other new users like, such as wifi1, capture2024 Procedure Login to Linux as root, or use one of the following su - sudo su - Find out the physical device ID using "iw dev" command It will dis...

 Product: BenQ EX3501R Ultra Wide 35" Monitor AMD Radeon Ver 2021/-511.1532.24954 GPU: AMD Radeon HD 7870 Bought the popular 35" ultra wide monitor that support 3440x1440 30Hz HDR.  Tried to configure it to work with older AMD GPU, but found that Windows 10 doesn't offer a list of this resolution. All the detected resolutions are leadings to improper size, and not fill up the entire monitor. After days of testing, and struggling, then I found that I have to install the full Radeon driver in order to launch AMD Radeon Softwere to be able to create custom display resolution. When I got into the custom display resolution screen, then I was confused with a series of values to enter.  BenQ homepage provides no help to fill in the values, so I have to look online how to derive all these parameters based on the resolution of 3440x1440 29.970Hz refresh rate (got the refresh rate from other GPU that works). Following are the values you should enter when creating a custom 3440x1440...
