tdrdelay

The tdrdelay tag on WindowsForum.com covers discussions about the TDR (Timeout, Detection, and Recovery) delay registry value, which is often adjusted to fix the 'Display driver stopped responding and has recovered' error. This error typically occurs when a graphics driver fails to respond within a set time, causing the screen to go black temporarily. Users experiencing this issue with unsupported or older graphics cards, such as switchable Intel and Radeon setups, may attempt to modify the TdrDelay registry key to extend the timeout period. The tag includes troubleshooting steps like driver updates and registry edits, though success varies depending on hardware and driver support.
