HBO’s first-ever streaming service, HBO Now, launched in 2015 and became a huge success. In 2018, the company announced an upcoming subscription video service called HBO Max that is scheduled to launch in 2020. The company is planning some big changes for this new service, including offering a library of 10,000 hours of content (compared to 1,500 hours on HBO Now), along with exclusive programming like the J.J. Abrams-produced sci-fi anthology show “Demimonde.”


HDR is a new standard for High Dynamic Range. It is the result of cooperation between major TV manufacturers and it elevates picture quality to a whole new level with a wider range of brightness and contrast, extraordinarily bright, dark or colorful images and more detail in both very bright and dark areas.

In addition to HDR support, regular high-definition televisions (like the one you own) are gradually introduced with technologies that offer more lifelike picture quality. This is done by increasing resolution (sharpness), color depth (number of colors) and/or brightness (peak light output).

Color Range

TVs display colors using the RGB (red, green and blue) color system. The more bits that are used for this purpose, the more detailed (more accurate) the colors will be displayed by your TV. TVs today have 6-bits for red/green/blue or 18-bits in total to render colors. 8-bit (24-bit in total) TVs deliver the best color results and they support the full Rec. 709 spec (which is used for HDTVs). 10-bit (30-bit in total) TVs can show more colors than 8-bit sets and offer a more saturated picture, but wide color gamut TVs are not supported by all entertainment sources and content (such as Netflix) and they usually require a wider color gamut source to display accurate colors.


TVs deliver better image quality when they are capable of producing very bright and very dark images. This is especially important in darker home environments. A peak brightness of 400-500 nits (for SDR TVs) and about 1000 nits (or more) for HDR10 compliant sets will produce the best results.


Contrast ratio is the difference between the darkest black and the brightest white a display can produce. It has a major impact on picture quality, especially when watching HDR content with a very high peak brightness where bright objects stand out from the dark background. A higher contrast gives deeper blacks and better image depth, which results in more vibrant colors and vivid details. We recommend sets with a contrast ratio of at least 6000:1, but you can still get good results from TVs with lower contrast ratios if they have a wide color gamut and very accurate colors.


Sharpness is a measurement of resolution. It defines how clear and detailed images will look on the TV screen. A higher resolution means that objects will be rendered with more details when viewed from a close distance or that they will appear larger when watched from a distance.

Tint (G/R)

Tint (also called ‘balance’) is the difference between colors red and green. A tint problem will manifest as either a greenish or reddish cast in pictures. The issue can arise due to a number of reasons, but it usually appears when faulty TV settings are used (incorrect color temperature).

Why is my HBO max screen black

There could be a number of reasons why your HBO Max screen is black. One possibility is that you may not be subscribed to the service. Another reason could be that there is an issue with your device or your internet connection. You may also need to update your device’s software in order to access HBO Max. If none of those solutions work, you can contact customer service for assistance.


HBO Max is a new service that offers streaming TV, movies and original programming. It’s also the first stand-alone HBO service to stream content in 4K HDR. This means you can watch your favorite shows with amazing picture quality – even if you don’t have access to premium cable channels like HBO or Cinemax!
