Black Screen Issue While Running LabVIEW Application

[ravikiliki]

 HI everyone,

Black screen problems have started occurring when I run my LabVIEW application on my system. The screen goes blank during execution, and the system becomes unresponsive, requiring a restart.

Iam using LabVIEW 2023 on Windows 11 with an AMD Radeon RX 6700 XT GPU. The issue started after a recent driver update. I have tried reinstalling LabVIEW, rolling back the GPU driver, and checking my display settings, but the problem persists.

Could this be related to LabVIEW's interaction with my GPU or system settings? Has anyone faced a similar issue or found a solution?

Any advice or troubleshooting tips would be greatly appreciated. Thank you!

We have the same issue, but it depends on the computer. On some, it never happens, while on others it occurs often, with either 5 minutes or up to 5 hours of latency before the problem appears.

Do you happen to use DAQmx or some other NI hardware driver? Have you tried to update these drivers to the greatest and latest (or if you don't use the according hardware to simply not install them)?

under this application no especial hardware are related, only Visa, communicatrions ports, and CAN interfaces, we use IXXAT usb to can, and several rs232 ports

First it does not matter if you use DAQmx hardware or not, the important part is if you installed NI software drivers, DAQmx, PXI, VISA etc. You say you did install VISA. While VISA may sound harmless, it usually comes also with PXI drivers, unless you specifically disable that and those drivers all rely on the NI PAL low level software which goes deeply into the system PCI device drivers. And NI PAL device drivers can definitely cause problems on newer chipsets and CPUs. The solution is either to deinstall those drivers or upgrade them to the latest version.

So that may be one thing to try out. The reason is that new chipsets introduce often new features that Microsoft then enables in newer Windows updates if they detect those chipsets and that can throw off older drivers that were designed and tested without those features available.

And are you sure you are using the latest version of the IXXAT drivers? They tend not to go as deep into the system drivers as the NI driver stack, but who knows!
