DTrol vs Pixel Density Calculator

DTrol turns your iPhone and iPad into a fast, reliable, two-way remote for your network-connected NAD and Anthem A/V processors and receivers — controlling power, mute, volume, source, and tuner presets on all your zones. That's it — and that's probably all you need most of the time. DTrol is a zone controller: it focuses on the functions you reach for every day and does them well — just like remotes used to be. **Control Every Zone** Power, mute, volume, source, and tuner presets — zone by zone, across multiple processors and receivers. **Make It Yours** Rename zones and sources, adjust their details, and set up links that launch your source apps. Changes live in DTrol only — nothing on your equipment is modified. **Two-Way and Live** DTrol shows the real state of your equipment, not just the last button you pressed. It stays in sync with what's playing and lets you know if a device stops responding. **Direct and Private** DTrol talks to your equipment directly over your home network. There's no account, nothing in the cloud, and no personal data collected. Your setup stays on your device. **Your Setup Carries Over** Upgrading from an earlier version of DTrol? Your servers, zones, and settings come with you automatically — nothing to set up again. **Supports** - Known to support: NAD T175, T175 HD, T765, T775, T785, T187, T777, M15, M15 HD; Anthem AVM 50v and Statement D2v (and variants - the legacy AVM control protocol) - Designed to also support: NAD T755; Anthem AVM 20, AVM 30, AVM 40, AVM 50 - Likely supports other models that speak the same NAD or Anthem legacy protocols - Your processor or receiver must be reachable on your home network — via its Ethernet port if it has one, or through a device that bridges your network to its RS-232 port, such as the Global Caché iTach IP2SL, iTach WF2SL, or Flex - Controlled devices must have a static IP address — this keeps DTrol fast and stable. If a device's IP address changes, re-add it in DTrol. - For more help with network configuration, see the support page: https://dtrol.fastfiveproducts.com/ **Setup** With your processor/receiver and your iPhone or iPad on the same network, tap "+" in DTrol to add your equipment as a DTrol "Server" — you'll need its static IP address and port. DTrol queries the device and sets up your Zones and Sources automatically; afterward you can adjust Zone names, Source names, and other details in Settings. DTrol is free. It requires iOS 18 and a local-network connection to your equipment.

Pixel Density Calculator are used for calculating pixels per inch (PPI) or dots per inch (DPI) of any display based on its dimensions and the pixel count. PPI is a measure of pixel density or resolution of a monitors, smartphones, tablets, smart watches, computer screen, notebooks, television screen or other display device. Pixels per inch indicates how many pixels are in a 1 inch line on a display. Also calculated are screen size, screen width, screen height, aspect ratio and total number of megapixels. Calculation including shape preview. The formula to calculate PPI from diagonal: PPI = √(w² + h²)/d where: d – Diagonal screen size in inches. w – Number of pixels along the horizontal line. h – Number of pixels along the vertical line. Calculate the number of pixels that fit on the diagonal: d = √(w² + h²) where: w - Number of pixels along the horizontal line. h - Number of pixels along the vertical line. Then, calculate the PPI as the ratio between the number of pixels along the diagonal and the diagonal screen size: PPI = d/di where di is the diagonal screen size in inches. Pixels per Inch Quality value 120 PPI - Low 120-160 PPI - Medium 160-213 PPI - Medium High 213-240 PPI - High 240-320 PPI - eXtra High 320-480 PPI - eXtra x2 High 480-640 PPI - eXtra x3 High What is pixel density: Pixels per inch (PPI) are a measurement of the pixel density (resolution) of devices in various contexts: typically computer LCD or OLED displays, image scanners, and digital camera image sensors. The PPI of a computer display is related to the size of the display in inches and the total number of pixels in the horizontal and vertical directions. The PPI and DPI definitions are essentially equivalent. Dots per inch, or DPI, is comparable to pixels per inch. Thanks for your support and do visit nitrio.com for more apps for your iOS devices.
