i also beoing the TV but dont think it's sold in singapore, yet.
Heard it'll be coming in 2021 from BD people.
i'm currently using the 55cx as monitor. 1.80m viewing distance. Nice and comfortable. Blows any IPS screen out of the water in every aspect. Burn in risk is there, but mitigated by some care. Like auto hide task bar, dark/black theme, not leaving static elements on for long time.
I think LG has done a lot in the C9 and especially CX, to mitigate the burn in risk. They market the 48CX aggressively as a gaming TV. If burn-in was really such a big problem on this generation of OLEDs i doubt they dare to do it
4k @ 55" has low PPI in theory, but due to the required viewing distance for good ergonomics and eye comfort, text still looks very sharp. The OLED renders text much nicer than my non OLED sony x900e VA. Not sure why, but it just looks better on the OLED.
For hardcore excel/word/productivity tasks i still use my monitor. For games/media consumption the OLED is king.
It's hard to articulate how much of a leapfrog upgrade the perfect blacks, infinite contrast and color reproduction looks like. The OLED pixel response time is also faster so everything feels much more snappy. Even gaming at 4K, 60hz also feels more fluid, versus 1440p 60hz.
If the user can increase the viewing distance from the tv to around 1.6 to 1.8m, a 55" oled is a solid choice. I do this with a cheap ikea linnmon 100x60cm table that is light enough to shift easily, but still reasonably sturdy. Acting like a mobile desk, essentially.
