**this is my configuration (bought it 1 month ago):
Dell SE2717H (I've had 2 identical, same problem with both of them)
Cavo HDMI 5mt (I see it has the label High speed Ethernet cable)
Sapphire Pulse RX580 8GB (coil whine under load)
Ryzen 1500x (small +10°C peaks under benchmark)
Corsair Vengeance DDR4 2x4GB 3200Mhz (ok)
B350 Tomahawk (ok)
Thermaltake Smart SE 530W (ok)
Samsung 850 EVO 500 (ok)
Seagate Barracuda 2TB (ok)
Case Fractal Define S (ok)
Windows 10 Pro (ok)
AMD driver 18.1.1 (same problem with the previous 2 versions)
Freesync via HDMI cable, monitor support it and it has only HDMI and VGA ports.
**this is my problem:
3 weeks of normal usage without freesync monitor and then I bought it.
It started 4-5 days ago, I use to power off pc during the night (remove power cable from the wall), when I power it again in the morning and open application such as Battlefield 1 (Youtube too in certain videos) it start to show black screens (black screen flickering) the screen seems to be turned off (no backlight) and then it goes back to normal image. It often resize the image in the wrong way and the frame appears bad-sized.. other times the black screen has backlight
**how I fix it till the next power off (next day):
1) I can remove and reinsert HDMI cable (GPU side or monitor side, no matter) this resolve the problem till the next time i power the pc off for long times..
2) Disable FREESYNC in driver menu
3) Restart PC
All this solutions works till the next power off
**Someone has an idea of what's my problem? Bad GPU? Bad cable? Bad monitor?
I have video of flickering if needed.
Thank you all in advance
