LG 32LN5300 is a lousy product for several reasons. Most relevant to this audience: it regulates brightness by rapidly flickering its backlight, "PWM dimming".
This television monitor's backlight intenisty can be set anywhere between 101 settable points, 0 to 100. It flickers at any level less than high brightness: I can detect flicker at up-to setting 90, by wagging my finger and looking with my naked eyes. Over backlight level 90, it still flickers, but it gets milder and less detectable approaching 100 (maybe lower flicker amplitude?). At moderate-high brightness (settings 70–90), I can watch TV without noticing flicker, unless I am trying to detect it and not concentrate on program content. Flicker at backlight brightnesses below 60 is unpleasant, detectable with eye motion. At low backlight settings (say, below 20), flicker is high amplitude, might be one hundred percent flicker. (That is not to say that moderate brightness points use low amplitude flicker-dimming. Simply, the lower the brightness, the worse the PWM effect.)
Full brightness, "100" backlight, is far too bright for a dark room. Because I hate flicker, I always operate it at "full one hundred", and at night, I use 200W-equivalent room light. Even at its darkest "0" setting, this TV monitor is too bright (for me) in a dark room.
This product will kill itself at full brightness. It is planned obsolete: it is under-engineered and will not last, or, it is engineered to fail. Backlight at full brightness cannot shed its heat. This is common; expected, even; in such big and cheap, "quantity over quality", LED-backlit panel televisions.
This product is not ergonomic, or, it has a low usability score. It has NO ACCESSIBLE control buttons. Power and the bare-bone minimum other buttons (channel+volume) are in back, in a straight line, and all feel alike.
To use its remote control requires visual concentration. (Effort is required just to hold it, being a skinny, long, non-uniformly weighted, wedge-rectangle.) Buttons are packed together, like on pocket calculator, in an arrangement/layout which is very difficult to memorise, difficult to identify by feel, very easy to press a wrong button by mistake. IR beam strength / reception performance is lower than I would like. Pressing mute three times pops-up a prompt to reset audio+picture settings. This is bloody annoying. Who ever asked for this?
This television monitor has too few inputs: one. It has one, only one, analog AV source input, which can be treated as CVBS or YPbPr. YPbPr mode disables, does not allow, closed captions. (I've used a Samsung/Assmung televisionset which does not register/accept CC on Y as in YPbPr. Is this deficiency unique to these Korean brands?)
Tools should do their jobs well. LG 32LN5300 can't do much at all well. It is a throw-away product of our throw-away society. It is not fit to exist. Less electrotrash is better than more. I would not pay a nickel, I would not give a penny, to take posession of a LG ##LN5300.
I found two prior observations/reports of backlight flicker in LG LN5300 line/range.

I have the 42LN5300 … I wanted to mention that this LG does use a PWM backlight like the sammy.

MrMike: The LG 32LN5300 … Has anyone tested it for PWM?
Xr7: Yes I have actually owned one and it wasn't until this tv that I realized PWM affected me.
