LCDTester 1.0
Quickly check your new LCD monitor for dead pixels

LCDTester is a tiny tool which can help you check an LCD display for stuck or dead pixels.

To use the program, just launch it, click Begin, and the screen will turn entirely white. If you have a "problem" pixel then it may stand out as being a different colour or brightness to its immediate neighbours.

It's hard to tell immediately, though, so LCDTester will cycle the screen through several solid colours every time you click the mouse: white, black, red, green, blue, and back to white again. By quickly moving from one colour to the next it's much easier to spot a defective pixel.

And when you've finished inspecting the monitor, just press the Esc key to return to the regular Windows display and carry on as before.

It's all very simple and straightforward, and as an added convenience, LCDTester is also portable. If you're going to visit someone, hoping to buy a second-hand display, then take LCDTester along on a USB key and you'll be able to run it from there, no installation required, just to check it's all working properly before you buy.


LCDTester uses a very simple technique, but it can be surprisingly effective in helping you spot dead display pixels.

WhatsApp Messenger 2.12.11

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

Version 2.12.11 brings:

• Links that you share or receive will now include a rich preview. When sending a link, you have the option to not include a rich preview.
• Additional 3D Touch features: You can now quickly Peek and Pop chats.
• Redesigned Settings tab. 
• You can now view all your starred messages across all your chats in Settings — Starred Messages.
