Screen Flickering and Loss of Signal in Client

[Casti_EL]

Could be the refresh rate causing issues (144Hz) if you haven't already tried limiting it - I had issues with a Radeon card/ freesync monitor doing similar things in the game (and a couple of other older ones) - blacking out, flickering. Got advice to force it to 60Hz and had no further issues until the card itself blew.

Hi there, that worked, but is there no way to have it at 144hz then? I just have to play at 60hz?

If it is a FreeSync monitor (or GSync, but you have a Radeon in that system information so I'm assuming FreeSync if applicable), the monitor manufacturer may have the FreeSync mode locked to a specific range of refresh frequency, and if that range and what the game outputs and what the monitor will really do don't all match up, you'll have 1-2s blackouts periodically as they fall out of sync. This is considerably more common with FreeSync/Gsync and 1440p144 both enabled.

If that is what's happening, your solutions there are either to disable FreeSync entirely, lock video to a refresh rate in a 'safe' range, or edit your monitor's advertised information such that it will advertise a more appropriate range for FreeSync. (The last one is annoying to do, plus will 100% violate your warranty and also potentially damage your monitor if you overwrite the wrong things. I'd consider it a last resort.)

Or just lock it at 60hz and live with it, which is probably the easiest fix of all.

Another possible cause of signal drop is a bad monitor cable... or a connection with insufficient throughput. DisplayPort seems to work better for 1440p144, where HDMI 2.0 will generally work, and Dual-link DVI is (unfortunately) hit or miss on some monitors I've encountered; usually that presents as a complete failure to output graphics at all, but I've seen it cause signal drops in a few cases. It's a lot less likely, but at least "buy a DisplayPort cable" is not the most inconvenient possible fix here.
