Intermittent black screen during gaming


Some time ago I started having this issue with my computer where certain games would make my TV screen turn black like it was changing channels and come back intermittently. It only happened when I play certain games (at first but now it happens when I stream Netflix.) I've since upgraded my TV and graphics card and the problem has gotten worse. I've updated all drivers, through the installer and manually, I've switched HDMI cords trying three different ones, changed different settings on the TV, tried different resolutions, and thinking it was an overheating issue, I hooked up another fan to increase air flow. It seemed to help at first but it's since gone downhill. Could it still be an overheating thing? I don't think it's the card because my previous one did it too. I went from an AMD R9 200 series to an RX 580. I can play Hearthstone and Slay the Spire with no issue but if I play something like Far Cry 5 or Anthem, it will do it.

Can you do a Speccy test and give us some information from it,  it monitors your computer and gives you readings of most of the internals in your computer as well as the temperatures for CPU, Video Cards, Motherboard and Storage

Select the Free Version,  Click here ===> Speccy  make sure to check out the temperatures when playing the different games.


You may prefer another monitoring tool,  but let us know what you see when monitoring those readings as well as RAM and what kind of computer System your running.

The flickering doesn't sound like an overheating issue. Does the computer behave normally otherwise? Speeds seem good, no stuttering? No lag? 

Is the computer a custom build or a major brand name? 

Regarding the HDMI cables, are they all newer cables--spec wise? You should make sure you have an HDMI 2.0 cable for the best speed. Although you changed the cable out three times, flickering or turning black for a few seconds is an indicator of a bad cable. Good luck!

I downloaded speccy and played Slay the Spire to see what the temperatures did and while the GPU was idling at 50, everything else was 40 or below. The highest the temp got to was 67-70. It started to do the flicker, which it had never done during this game before. I went into MSI Afterburner and put the fan speed for the GPU to 100% and the temperature dropped below 40. Started playing the game again and it still happened with the temperatures not going above 50-60. 

Operating System
            Windows 10 Home 64-bit
            AMD FX-8320    31 °C
            Vishera 32nm Technology
            10.0GB Single-Channel DDR3 @ 669MHz (9-9-9-23)
            Gigabyte Technology Co. Ltd. 990FXA-UD3 (CPU 1)    32 °C
            SAMSUNG (3840x2160@59Hz)
            8192MB ATI Radeon RX 580 Series (XFX Pine Group)    34 °C
            931GB Western Digital WDC WD10EZEX-08WN4A0 (SATA )    36 °C
            223GB SanDisk SDSSDA240G ATA Device (SATA (SSD))    38 °C
        Optical Drives
            HL-DT-ST DVD+-RW GSA-H73N
            AMD High Definition Audio Device

That's what I'm working with. It's a homebuilt machine and it has no other apparent issues like the ones mentioned. That's what makes me believe it isn't a hardware problem. When the flickering happens, the sound cuts out as well like it's changing sources on the TV for a split second. The other HDMI cables I tried should be 2.0. One came with my PS4 Pro and the other one I bought to use with it because it was longer. They both work just fine with the console.
