it is the c1 model , and it was out of warranty when it started showing problem which was around 3 months just after warranty expired, hopefully c2 oleds last longer than c1 , but as a word of caution try to keep the brightness at the minimum and try to run pixel refresh utility at least monthly.
in my case i had chrome open 24x7 and it started showing the scroll bar on the right and other static elements , they disappeared after refreshing the pixel but once it started they would appear again only after few hours of use , so i re purposed it as a TV again before it went completely kaput.
havent faced any issue in using as a TV , but oleds simply aren't cut out for 24*7 use with static content yet.
