Driver issues with OS 26 with M2
Driver issues with OS 26 with M2 - Constant screen refresh when returning from Standby when laptop is closed
I even did a complete reinstall by erasing the entire OS and rolling back My MacBook Pro M2 from OS 26.2 to 26.1
I tried all of these models on the following computers using the same Asus monitors and monitor cables. Add device models are attached in the images. All are using the latest DisplayLink Drivers (15.0.0 Build 22)
MacBook Pro M2 OS 26.2
Dock WL-UG69PD8 Pro Rev.a - Syncs on initial connection after a few screen flashes, returning from standby it constantly flashes monitors and sometimes all screens go blank and stop flashing.
Dock Model WL-UG75PD1-4H2 Rev.b - Syncs on initial connection after a few screen flashes, returning from standby it constantly flashes monitors and never finishes syncing.
Dock UDS 033C - Syncs on initial connection after a few screen flashes, returning from standby it constantly flashes monitors and never finishes syncing. Sometimes one random monitor will sync
Dock DK31C3HDPD - Works
MacBook Air M2 OS 26.1
Dock WL-UG69PD8 Pro Rev.a - Syncs on initial connection after a few screen flashes, returning from standby it constantly flashes monitors and sometimes all screens go blank and stop flashing.
Dock Model WL-UG75PD1-4H2 Rev.b - Syncs on initial connection after a few screen flashes, returning from standby it constantly flashes monitors and never finishes syncing.
Dock UDS 033C - Syncs on initial connection after a few screen flashes, returning from standby it constantly flashes monitors and never finishes syncing. Sometimes one random monitor will sync
Dock DK31C3HDPD - Works
MacBook Pro Intel 2018 OS Sequoia 15.5
Dock WL-UG69PD8 Pro Rev.a - Works
Dock Model WL-UG75PD1-4H2 Rev.b - Works
Dock UDS 033C - Works

To improve the performance of your computer systems, it’s important to know about the idea of a bottleneck. A bottleneck occurs when a single component in the system limits its overall efficiency or slow down its performance. For any PC user who wants to improve their computer’s capabilities it’s essential to know the drawbacks of the bottlenecks and how to prevent them. https://bottleneckcalculatr.com/

A PC Bottleneck Calculator helps users identify performance limitations in their system. It explains how one component, like CPU or GPU, can slow down the entire computer. By understanding bottlenecks, users can optimize their setup, improve efficiency, and make better upgrade decisions for smoother performance and enhanced computing experience. https://bottleneckcalculatr.com/

De koelkast stopte met werken tijdens een hittegolf en al mijn eten begon meteen te bederven. Een nieuwe kopen was financieel een absolute ramp deze maand. Gefrustreerd opende ik https://boomzino.be terwijl ik zat te balen. Ik raakte een enorme winstlijn die me in staat stelde om een gigantische Amerikaanse koelkast te bestellen en de kasten weer helemaal vol te steken

Some of these M2 display issues seem related to how hardware bandwidth is managed when waking from standby. Tools like https://thepcbottleneckcalculator.com/ can help identify if PCIe or other internal lanes could be a limiting factor, which might explain why some docks behave differently. It’s interesting how small hardware differences can impact driver stability so noticeably.
