have you been in the market for a new TV lately if so you've probably noticed that the TV manufacturers and big-box stores use a number of tricks to lure you in they mostly focus their advertising on the same stuff high resolutions huge screen sizes and rock-bottom prices all designed to convince you to punch and elbow your way past a bunch of strangers on Black Friday like some sort of electronics piranha but there's a crucial often ignored element one that is arguably the biggest determinant of overall picture quality contrast ratio but what the heck is that well although it's not something that's always easy to find if you're buying a TV or a monitor off the shelf at a brick-and-mortar store you should have encountered contrast ratio at some point on a spec page if you're shopping online but what do those values one thousand to one 1 billion to one even mean well you see contrast ratio is essentially the difference between the brightest white that a screen can produce and the darkest black which is very important because having the correct brightness on different areas on screen is critical for making dark areas look sufficiently dark without losing detail and for optimal visibility in bright areas think of a shot of a city at night a TV with good contrast will clearly show you a dark night sky while making the detail of the city lights stand out if your screens contrast ratio is too low the entire scene will be less detailed and more washed out with dull stars on a charcoal backdrop typically modern IPS displays as well as better made TN panels will offer contrast ratios in the neighborhood of a thousand to one meaning the brightest pixel will be a thousand times brighter than the dimmest if you opt for a more unusual VA type display you'll generally see better performance at least by this particular metric with contrast ratios between two and five thousand to one but what about those spec sheets you see that advertised insane contrast ratios of like ten million to one well if you look closely you'll see that these numbers indicate a dynamic contrast ratio which is a number that a manufacturer claims a display can achieve with backlight trickery so on lower-end sets the entire backlight will be turned up or down depending on the brightness of the scene while on high-end ones this is done more granularly with certain parts of the scene being boosted or dimmed these dimming techniques are quite useful and can result in better picture quality but the experience definitely isn't the same as having a panel that can achieve natively an absurdly high contrast ratio like an OLED one whose pixels individually emit their own light without any backlight allowing them to perform this dimming functionality on a per pixel level they can even be turned off so long story short then unless we're talking about OLED you should take those 10 million to one numbers with a huge grain of salt and for that matter even OLED that might really have 10 million to 1 contrast ratios are sometimes advertised as having infinite contrast that should really be undefined if you don't like / 0 error so you guys speaking of / 0 and math errors do you find a counting complicated do you wish as a small business owner or freelancer that you could just spend your time doing your work and you could just like carry your accounting solution around in your pocket well FreshBooks has you covered and at the link in the video description you can try out fresh books for absolutely free it allows you to send invoices in a matter of minutes that look professional it allows you to track your expenses it allows you to track your hours and it even allows you to take money on your own terms you can accept payments through the app you can take deposits and you can see when your client has seen the invoice which is a pretty huge benefit put an end to those guessing games once and for all so try it out for 30 days by going to FreshBooks comm slash tech flicky and Entering tech quickie in the how did you hear about us section ok come on in here if you want to be in the video then you might as well come be in the video were you interrupting daddy's ad spot were you yeah you were so thanks for watching guys if you just like dislike but if you liked hit the like button get subscribed leave a comment if you have suggestions for future videos and oh yeah check out our other channels you again next time
