Samsung 55H6500 -> ANSI contrast 3208:1
LG 42LB650V -> ANSI 921:1
H6500 είναι εξοπλισμένο με οθόνη της Samsung VA με καλή αντίθεση και το μαύρο, το οποίο επιβεβαιώθηκε από τις μετρήσεις. Σαφώς ορατό είναι ένα καλύτερο αποτέλεσμα σε σύγκριση με της LG LB650V μοντέλο, το οποίο IPS πάνελ επιτυγχάνει ακόμη και τρεις φορές χαμηλότερη αντίθεση, καθιστώντας την εικόνα της χλωμό και η έλλειψη καλής ποιότητας κινηματογράφου αίσθηση.

And along with IPS panels come these shortcomings:
Low contrast: the LA690V has a contrast ratio of 620:1, at a time when most competing TVs have at least 2,000:1. The untrained eye may not notice it with the lights on, but once you turn the lights off, anything black will look washed out (like the black widescreen bars in the image above). This is such a crucial part of a TV's picture quality that in our rating system, any TV with contrast this low is necessarily limited to three out of five stars on its overall score.
Low responsiveness: with an average ghosting time of 13 milliseconds, the LA690V comes in at the bottom of the list among the TVs we've reviewed; it's far less responsive than plasma, S-PVA or UV²A.

If you’re used to watching a VA LCD panel or – heaven forbid – plasma television, then the 49UB850V will give you a nasty shock. While boasting wide viewing angles by LED LCD standards, LG’s IPS panel produced mediocre blacks, measuring 0.157 cd/m2 on a 4×4 ANSI chequerboard pattern (peak white was aligned to 120 cd/m2 as we usually do in all our TV reviews). Consequently, a layer of grey mist descended upon portions of the picture that should look black, robbing the image of any punch. The compressed dynamic range also led to obscured shadow detail.
