I have a main monitor Acer KG241 Pbmidpx, its a cheap but 144hz 1080p monitor connected with a DP cable which servers its purpose, 2nd monitor (to the left) is a LG M2394A 60hz 1080p connected with an HDMI cable which is kinda old and its pixel density is bad but for now i cant afford a new one, when i first set up the dual monitors about a 2 months ago ( added the LG one next to the Acer one which ive had for around 8 months now) all was working well then around one month ago the LG monitor would go black for around a second every 4-8mins, i wasnt bothered but a few weeks back it started happening once every minute and now its 2 times a minute and it turns my Acer main monitor off with it aswell. Is it my GPU? i obviously cant afford a new GPU but its still under warranty although i do tweak it with MSI Afterburner from time to time so it might be voided.
