Radeon R7 240 blinks in win 10

[CodrinMarius]

HI,

I have a radeon r7 240, the 1gb DDR5 version, on an system with intel i5 4460, 2X4g ram 1866, 120 ssd on ASRock z97 pro3.
The driver is the newest 15.300.1025.0. Had the latest beta before.

Problem is that in Win 10 64 bit, it blinks. Meaning, once in a while, like in games and more often when flash player runs in a browser (maybe a coincidence), though it would do it while I write a word doc. The blink is like a black screen for 1-2 seconds (like when you install a new vga driver and sometimes blinks). Some of these times, I have to unplug my hdmi because it will not send sound to the monitor. After I unplug and plug back in the cable, the sound is back. It's really annoying.

The last month I had an older driver. Same thing. Updated to the beta. Same thing. So for the last month I've been using the integrated board. Absolutely no blinking with that. This week, I pluged the board and updated to this even newer driver. Same problem.

I should look around to sell the videoboard, right? )

try a new hdmi cord?

I tried a new cable, i changed it with the xbox one I knew works no problem.. The cable on the pc was brand new, and it makes no problem on the xbox nowl.

it would be strange to be a cable problem, it should have done the same blinking with the onboard graphics, not just the dedicated.

it was the cable

Not all cables are created equal and not all devices have the same tolerances, including between and within batches. That can create unique situations that logically make no sense. Glad to hear you found your problem!

You tried the cable again after 8 years?!

That reminds me of an old CRT monitor I had, where you could occasionally hear something in it click, it would go black for a very short instant, and everything sort of refreshed or resized - sort of like when you pressed 'degauss' on some monitors.
