I just bought a Philips 32PFL4505D/F7 to use as a PC monitor via a DVI-to-HDMI cable.
How can I disable the automatic brightness adjustment of the backlight? It becomes very annoying when scrolling web pages or switching applications.
Also, I hear some whining (from PWM?) when using Eco mode to dim the backlight brightness. Do all Philips LED TVs have this problem?
