Is their any way to force the lcd to stay on? Whats the point of having it when it only stay on for a couple minutes.
The issue is that the display is actually a OLED, Organic LED, which has a finite, and somewhat short lifespan. Until recently, even very high-end OLED Televisions have less than 30,000 hours, which would translate into less than three and a half years of constant use. That's of course based on a Mean Time Before Failures (MTBF) which tend to be overly optimistic.
I don't know the specifics of the OLED panel that they chose to use in the DGL-4500, but I'm pretty certain it's why they don't allow the display to stay on for long periods of time.
Hope that helps,
Hank
