TestCard ProHD 4k1.76 - App Store

Professionals use test cards to calibrate broadcast systems and cinemas use them too, so why shouldn’t home cinemas or theatres use them too? TestCard ProHD is the innovative means to calibrating your screen to ensure a consistent and correct representation of display media. (In-App purchase required after ensuring this will work on your TV / Display.)

** In-App purchase required after compatibility testing for full functionality. See below for why. **

Additionally, TestCard ProHD also now includes an SPL or “decibel” meter to assist with setting up surround sound sources. It’s a solution for calibrating both audio and visual elements within the home that can also be used in professional environments.

Newest version now includes a Audio Visual Synchronisation test to help diagnose lip-sync issues.

TestCard ProHD is the application for setting up a modern High Definition TV or projector. We’ve grouped together some common types of test cards as well as some new ones that will help set up home theaters to a professional standard.

Adjusting the contrast and brightness is essential to ensuring that you get the best from your TV or projector, but color is vitally important too. Further, test cards for motion and sharpness tweak more performance from your screen. Using these test cards and their instructions you’ll be able to tweak to get the best you can without the expensive of a dedicated calibration service.

Only by applying test cards in a controlled manner will you to get the best from your home theater and TestCard ProHD is the right tool, taking advantage of the unique abilities of the iPhone and iPad.

Within modern screens there are many techniques used to smooth motion. These can also have a detrimental effect, yet correctly set some do improve the picture. Having a repeating pattern to assist the setting of motion controls is essential. TestCard ProHD has test cards specifically design for motion testing on a screen.

Further, each test card has an information section to give you concise information and instruction on how to use it. The more that can be gained form each test card, the more information is provided. For ease of use the instruction are displayed on the iPhone / iPad while simultaneously displaying the test card on the external display.

Access to the test cards on the external display, Virtual Blue Filter and the SPL meter are only available after an In-App purchase. Using the default test screen please ensure that you have tested your device with the media adaptor, or Apple TV, on the external display before purchasing access. This is to allow you to verify that your system is fully compatible before purchase, and to share a single purchase with your iOS devices and Apple TV.

TestCard ProHD can be used with Apple TV V2, V3, V4 or V5 / 4k, or with the Apple media interfaces for HDMI or VGA.

Apple TV V2 and V3 can be used as the external display interface using AirPlay Mirroring. Simply switch on AirPlay on the iPhone or iPad and select Mirroring. See below for instructions on AirPlay Mirroring.

For HDMI or VGA Apple produces two types of media interface. While we’ve included some test cards for VGA / computer calibration, the home cinema user who is looking for 1080p compatibility should opt for the HDMI based media interface.

Apple TV version of the app is also available. Once access to the testcards is bought on either iOS or Apple TV app, you can have access on the other type of device without additional purchase. The In-App-Purchase is shared between all compatible devices registered on your Apple ID.

Apple TV AirPlay Instructions:
To enable AirPlay Mirroring connect your iOS device and your Apple TV to the same Wi-Fi network. For iOS 7 swipe up from the bottom of your screen to access Control Center. Tap on the AirPlay icon, select your Apple TV and switch on Mirroring. More details can be found on Apple’s support page http://support.apple.com/kb/ht5209

Remember, with TestCard ProHD you get this update without having to "buy the disc" again as you would with DVD or Blu Ray testcards! 1.35 04/05/2016 * New sections for Expanded Black TV.
* iPad Pro Support.

We're finding that some screens require calibration from the PC range of colors rather than Normal TV because of where their reference black is. So we've added new sections where we've adapted the existing test cards for brightness and contrast to work of the Extended Black / PC black reference.

The reason for this may be that the source and screen are automatically setting for "Extended Black", or "HDMI Full Range". Some screens will have this as an option which can be switched on or off, and it seems that some are now doing this automatically. In order to offer the correct test cards we've added cards to suit based upon the cards already provided, and updated instructions for them.

We've always intended TestCard ProHD to expand whenever someone asks for test cards to be added, and this is exactly what we're doing. There's no extra charges for these new cards - they're all delivered as part of the existing access. Simply update the app to get the new cards and there's no need to re-purchase as you would with DVD / Blu Ray based test cards.

Also adding support for iPad Pro. Essentially just adjusting placements to suit the larger screen. 1.30 11/20/2015 New graphical buttons!

After creating some graphical buttons for Home Theater SPL we just had to add graphical buttons to TestCard ProHD too.
