Dimming With HDMI PC input
Picked up my 55EF9500 on the 25th of September, and I've experienced some vignetting, that is mitigated almost completely, by lowering the brightness to anything less than 57, so, I might be able to live with that....however...
When I hook up my HTPC via HDMI, or my laptop...or any other computer, even with Energy Saving turned "off", I'm getting an unwanted dimming of the screen, whenever there is about one minute of inactivity on the screen.
The panel has done this with 4 different computers, on every HDMI input, without energy saving on, so, this is probably something engineered into the set, to prevent a static image from producing burn in.
I'm not very happy that I can't override this setting somehow, and I called LG VIP today, to ask about that, and the vignetting.
The person I talked to, "Neil", said he had never heard of the vignetting issue, and that he did not know if dimming the panel when it detects a static image, was engineered into the panel.
Anyway....Neil said he would call me "later in the day", but, yes, you guessed it, he didn't.
I have about 40 more days to preserve my return rights, and even if I can't stop the unwanted dimming, and eliminate completely the vignetting, I'll still probably keep the set, rationalizing that a little darkening of the edges, and dimming of the screen while in PC mode, is far preferable to blooming, grays appearing instead of black, and washout in off axis viewing, that are inherent in LCD/LED displays, compared to the no blooming and inky blacks of the OLED.
I'm asking any fellow EF9500 owner, if they could please hook up their PC to the panel, and let me know if you're seeing involuntary dimming of the display, at any time, whether you're static, or performing mouse or keyboard activity?
I really would appreciate someone else's evaluation and/or duplicating what I'm experiencing with my panel.
Thanks for all of your replies, in advance.
