Input lag desync PC and console

[bluca9211]

Only thing that worked for me was lifep04 battery, too much work trying to move house and hopefully find a place without the dirty electricity issue

Is this a UPS that uses lithium batteries?
Could you describe the problems you were experiencing and whether you managed to resolve them by using this device?

Ecoflow delta classic 3, power bank that I charge from wall then unplug and use pc and monitor from it. My issues were blurry display, distorted graphics, bad audio, the desync144hz feeling like 75hz etc. Running pc from wall outlet feels terrible, but the power bank feels great

I’m very glad you managed to resolve the issue; I’ll keep this tip in mind.
You mentioned:
1st, a type of screen freeze occurring while moving the mouse—it felt inconsistent with your set sensitivity (for example, at 800 DPI, it felt like double that, and the movement seemed "slippery").
Also, even with high FPS, you still perceived a significant delay.
This applies to both the desktop environment and in-game.

In fact, the best result I’ve had—lasting for at least two hours, with quick response and saturated colors—was when I connected a wire from the PC case to a bucket filled with soil, containing a copper rod about 40 cm long.
Like you, I suspect the grounding; I believe the resistance should be 2 ohms or less.

For me, it’s the opposite: my laptops and consoles work just fine—it’s only my PC that’s been giving me trouble. But I think I’m on the way to fixing that; I recently managed a partial solution, and I was even able to win a duel against a pro player with an Elo rating of 4000.

Buy console, high end TV like Bravia 9ii, blu ray, soundbar theatre 9 and subwoofer and forget about this input lag shit because in long term it will affect your happiness in my opinion. GTA6 soon btw, relax guys. I have the same problem with input lag but life goes on, this shit is not worth to take care too much. I finished resident evil requiem, resident evil 4, gta v and I am happy about that, it’s time to move to single player games. On other hand I play Fortnite on iPad because it’s easier for me somehow to play on iPad with controller with higher input lag or default deadzone- hard to say than on ps5 pro. Maybe somehow I’m getting easier lobbies? Relax guys… it’s really not worth to care too much
