Blacklight bleed

[jmartis]

Hey all, I just got this new 19" Philips monitor. Nothing expensive, but I haven't noticed any flaws except some backlight bleeding. I'm concerned only about the bleed at the top.
I just want your confirmation that this is normal Note this was photoed at low light, the area in the middle normally appears almost black.

I would REALLY hate to send it back. Only if it's not normal. Thanx for any help

Normal, unfortunately. Backlight bleeding, along with dead pixels, need to be abolished.

I have a dream and it is called OLED...

Ok, cool, thx Fortunately mine has 0 dead pixels (or I haven't noticed them so far).

hmm, I just noticed my panel emits a soft continouos beep... Not annying but 'just' audible from normal viewing distance. The weird thing is that upping the brightness gets rid of the sound.
Probably coming off the CFL inverter.

"Just audible" over the background noise from PC. So is this normal?

It happens only with some brightness values, I can make it completely go away with certain settings, but of course this is too limiting...

Also considered normal..

From a google search:

Depending on the type of circuitry the brightness reduction can sometimes result in oscillation, which is the buzz or occasional high pitched whine that occurs when the circuitry has to 'sink' unused power.

You get the same effect from household light dimmers if they are dimmed almost all the way down when there is a high wattage load on them (eg taking a half dozen 100W bulbs from full bright to dim)

Oh well, guess I'll have to live with it.

I'm pretty sure the problem could be fixed by potting the suspicious component (probably a transformer) in some kind of epoxy.

But considering today's trends of cutting the production costs down as much as possible, it's no surprise they didn't do that.

I often find it hard to find a quality product which suits my needs, even when money is not an issue. IMO, The quality of (electronic) products has dropped dramatically in the last 10 years.
