Image/video in the pc and in the mobile device

Ey readers!

Today in this post we're going to see the image and the video in our devices.

Nowadays it's impossible that devices like this doesn't has monitors, they are the window that connect the user with the machine. And, over time, we have been improving this technology to incredible levels as much as on the screen as on hardware and software. Inside the computer the graphics manager is the graphic or video card that converts binary data into images that are displayed on the computer's monitor. Today the most powerful video card on the market is the Nvidia GeForce GTX 1080 Ti.

MSI PE70 6QE

This laptop come with a 17.3" full hd (1920x180) built-in monitor pre-calibrated to be compatible with MSI true color technology, and a powerful GeForce GTX 960M.

• MSI true color technology is a series of procedures/methods applied by MSI on its notebook display to provide users a better visual experience with greater image details. First of all, a special software is used to check every panel’s performance. Each panel will then go through three color correction steps, including color temperature, color visible range and grayscale adjustment. Matrix Display supports 4K output up to 2 external monitors. 

• GeForce GTX 960M is a video card with great gameplay at high settings on 1080p resolutions, packed with inspired graphics technologies, and BatteryBoost for improved battery life you can game longer, unplugged.

GALAXY S6 EDGE

This mobile phone has a 2560 x 1440 pixels display of 5.1" with technology quad HD super AMOLED and Mali-T760, an integrated GPU that with the Exynos 7420 chip that works with a maximum frequency of 2.1GHz and 3GB of ram provides to the user a great visual experience.

• AMOLED stands for Active Matrix Organic Light-Emitting Diode. While this may sound complicated it actually isn't. We already encountered the active matrix in TFT LCD technology, and OLED is simply a term for another thin-film display technology. OLED is an organic material that, like the name implies, emits light when a current is passed through it. As opposed to LCD panels, which are back-lit, OLED displays are 'always off' unless the individual pixels are electrified. This means that OLED displays have much purer blacks and consume less energy when black or darker colors are displayed on-screen. However, lighter-colored themes on AMOLED screens use considerably more power than an LCD using the same theme. OLED screens are also more expensive to produce than LCD. 

• About the Mali-T760 I only find that it boosts the Midgard architecture into a new era of energy efficiency. Enhancements to the silicon-proven Midgard architecture ensure that the ARM Mali-T760 is the GPU of choice for all market-leading smartphones, tablets and DTVs. With full support for current and next generation graphics and compute APIs, it boasts stunning graphics and guarantees the excellent execution of compute-intensive tasks such as computational photography, gesture recognition and image stabilization.

SOUND IN DEVICES

Hello Bloggers!
Today we are going to talk about sound in our devices. As long as both are computers, even they are mobile, they have to use a sound card in order to treat sound and some speakers in order to hear it, of course. These cards are used mainly in order to change from analogic to digital sound and viceversa, and can be incorporated in the mother board or they can be installed separately. In the case of the speakers we will talk about some interesting specs.

MSi PE70 6QE:

This high-quality laptop contains 4 speakers and a subwoofer powered by DYNAUDIO, a powerful brand in the sound sector and a software called Nahimic Audio Enhancer that help the user by setting some sound presets for gaming, music, films...

As the sound card is integrated in the mother board and I prefer using an external sound card we will talk about the one that I use.

Line 6 UX1 Specs: 

1/4-inch input (adapter required for use with microphone) 

Balanced XLR input with mic preamp 

Trim knob 

Two 1/4-inch line inputs 

1/4-inch stereo monitor input 

Two 1/4-inch analog outs 

1/4-inch headphone out. 

USB bus-powered with LED status indicator 

Rock Solid ASIO, WDM and Mac® OS X Drivers 

This card is a little old but it can provide a good sound treatment for home studio purposes it provide us a bit depth maximum of 24 bits and as sampling frecuency ratio we get until 48 KHz, so this accomplish the standarts in professional music and cinema sound, so is a good component and cheaper than others. To have an external audio card is important so that the CPU is free of sound charge and the system will get a better performance.

About the speakers we can say that this system allows playing 4.1 configuration and as long as it have the subwoofer we will get better fidelity in the low frecuency ranges, we don't have their specs because they are not published in the dealer's web, but we can say that, for being a laptop sound system, it sounds great with a good frequency response and a good power.

Samsung Galaxy S6 Edge:

In this smartphone we get the next sound devices:
Wolfson WM1840 Audio Codec as sound card.
Maxim MAX98505 as amplificator.

Wolfson WM1840 is a microelectronic processor that i cannot find its specs anywhere, but it does a well sound treatment as we can prove in a experimental way.
Finally, as a conclusion we may say that sound is processed is computers with sound cards and it is played by speakers that can be active or passive (with the need of an external amplification). To choose a good sound card is a priority if you like sound, but you have to know its sampling ratio (Hz) and its bit depth, and for professional audio you must find as a minimum a sampling ratio of 48 KHz and a bit depth of 16 bits.

Thanks for reading and come again for knowing a little bit more about image in computers by the hand of my partner Esteban.

General description of our devices

Ey readers!!

Today in this morning we are going to analyze two of our device, a MSI computer of my university's partner and my Samsung galaxy s6 edge.

The computer is a 419(W)x280(D)x29(H)mm and 2.6 kg laptop which has a 17.3" Full HD (1920 x 1080), Wide-viewing angle screen. 4 Speakers, HD type webcam and a Single backlight keyboard (white).

Inside it we can find a Latest 6th Gen. Intel Core i7 processor, DDR4-2133, 2 slots, up to 32GB of RAM memory, a GeForce GTX 960M with 2GB DDR5 of dedicated memory and a 1 x 2.5" HDD + 1x M.2 PCI-E Gen3 x4 (NVMe) / SATA Combo SSD of storage. 

These components gives to the computer a huge power to work with images and sound software and play video games. 

The galaxy s6 edge is a 142.1 x 70.1 x 7mm and 132 g device with a super AMOLED 5.1 inches screen with gorilla glass 4, bluetooth 4.1, radio, NFC and Wi-Fi 802.11, A Octa-core (4x2.1 GHz Cortex-A57), 3 GB of RAM and 64 GB of storage. A powerful but ephemeral device, like all the mobile device today.
