Monitor looks different after power outage

[SsRicardoPT]

I just had some power outages and now that my PC is back up, the monitor looks different, I don´t know, it feels like it is discoloured or unfocused. I reset the monitor settings to default factory settings and it still looks discoloured/unfocused and I can also feel a bit more lag when I play LoL even though I have 60ms. So how can I put it back like how it was before?

My monitor is a VS228 Asus.
I don´t know if it will help, but could someone tell me the settings you use to browse the internet or to play games like LoL (brightness, saturation, resolution, contrast...)?

How is it connected?

Sometimes, with certain interfaces, if the power stutters when going down, it can mess up the negotiation between the source and the monitor. If it is connected by HDMI or Display Port, then try unplugging it and plugging it back in while both are fully powered up. It has been known to fix some issues with those interfaces.

If it is connected by VGA or DVI, then this method won't work.
