Question Second screen flickering

[joaoint]

Hi there,

All of sudently my desktop starts to flickering the image, it goes black for half a second, and the behaviour is random, it only does on the TV and not on the main monitor. If i connect my laptop to the TV it works fine.


Here is the list of things i have done.

• Change the hdmi cable
• Disconnect the main screen (Asus VG248QE) and let only the TV (Samsung UE50AU7105KXXC)
• Update drivers including NVIDIA card
• Update BIOS
• Test only with 1x8gb RAM on the different slots
• Test with another graphic card from other desktop
• Disconnect CD/DVD sata cable
• Disconnect SD card readerd sata cable
• Using only Display port on graphics card
• Different resolution
• Different refresh rate
• Format Windows

My setup:

• Nvidia Geforce gtx 660
• Intel core i5-4590
• 2x4gb Corsair ddr3
• Corsair cx500
• Motherboard Asus H81M-E
• Samsung SSD 850 EVO
• Seagate HDD ST500

My Screens:

• Asus VG248QE
• TV Samsung UE50AU7105KXXC

Desktop PSU = Corsair CX500

PSU - age, condition (orginal to build, new, refurbished, used)?

History of heavy use for gaming, video editing, or even bit-mining?

My Corsair cx500 PSU has 9 years, and i ocasionally play games but no video editing or bit-mining.

Thank you,

A 9 year old PSU is certainly suspect.

Very likely beyond its' designed in EOL (End of Life) and thus beginning to falter and fail.

Look in Reliability History/Monitor and Event Viewer.

What you are looking for are any errors, warnings, or even informational events being captured just before or at the times flickering begins.

Reliability Histor/Monitor is end user friendly and the timeline may reveal patterns.

Event Viewer is requires more time and effort to navigate and understand.
