problem solved. changed a completed new IPs one.
plz never ever use VA panel monitor, dont believe any bull bulls.. ppl trying to sell...
it is just bad, motion is bad, text is blurring, color is the worst, I still dont get the ideas to sacrifice so much just to let dark to be dark.....
anyway, avoid it at all cost, if you budget is limited, or just simply dont want to invest too much on Oled,, IPS is way to go,, or simply just use old ass lcd monitor,
even a 10 years old 32' lcd... is way better than VA crap.
lessons for me, hope helps some one want to upgrade there screen.
