Welcome to J.S. Technology.

BREXIT - NO UK VAT ON EU ORDERS!
As the UK is now a "third country" we no longer charge UK VAT on orders for the EU. UK VAT will no longer be collected by us on these orders. At the moment deliveries to the EU are not delayed and pass through customs quickly. If you have any questions please email us and we'll try our best to answer any concerns.
We're still trying to overcome the consequences of Brexit. To date we have not seen a single advantage in Brexit for business and especially individuals. However, we can assure our customers and friends around the world we will always support you. We will always answer your emails and we will always honour all warranties on our products.
Power Supplies.
Where possible we supply the correct power supply or lead for your country. For power supplies we are fully stocked for UK, European, USA and now Australia too (Australian is very hard to find in the UK!). Power lead (RGB to S-Video Converter V2) for UK or Europe stocked.
New Testcards and Information Screens for TestCard ProHD.
As always free to existing customers who now receive HDR testcards as well as brief information on HDR and LCD/LED & OLED screen technology. TestCard ProHD is available on iOS and Apple TV. 4k compatible (it always was).
On the Apple App Store:
New Innovation for TestCard ProHD - Virtual Blue Filter.
When calibrating colour it's best to use a blue filter. Now we have an assist within the App to help! A virtual blue filter using the device's own camera.
Remember - if using the Apple TV to produce testcards you can still have TestCard ProHD on your iPhone or iPad using the same purchase. No need to buy again when using the same Apple ID across all your devices.
As always, this update is available to all existing users for no extra purchase.
New Product Update! Digital Audio Lip Sync Delay.
Our Digital Audio Delay processor now becomes the Digital Audio Lip Sync Delay. The ideal way to delay audio to compensate for video processing delays in TVs when using an external amplifier.
App News: Loyalty Store and PIN Store Receives update.
As always, app updates are free to existing users.
TestCard ProHD now on Apple TV tvOS!
Re-written to run on the new Apple TV natively. No need for an iOS device to host, but best of all, existing customers of iOS version just need to "restore" purchase! New version for a new device, and no additional purchase required! That's the difference with J.S. Technology and our app, we're changing the rules!
We also listened to your feedback on the app being free to download, but you have to buy access to the testcards. Sadly, we can't make the app free as we need to eat too! We've always believed the fairest way to sell the app is to allow you to test that it will work with your hardware before you make a purchase.
Once again existing customers get this update for free without having to "buy the disc" again as you would with a DVD or Blu Ray based testcard.
