Menggunakan LCD Projector Dengan Ubuntu

Kebanyakan Ubuntu tidak bisa tampil dengan baik di LCD Projector, salah satunya dalam kasus ini kami menggunakan Laptop Acer Aspire 4520 dengan VGA Nvidia. Kami melakukan ujicoba menggunakan Ubuntu Fiesty/Linux Mint Cassandra. Berikut ini merupakan catatan eksperiment atau langkah-langkahnya:

projector.jpg

Pertama, bukalah file /etc/X11/xorg.conf, dengan perintah berikut

$ sudo gedit /etc/X11/xorg.conf

Kedua, edit beberapa bagian dari isi file tersebut

Pada bagian Section Screen, carilah baris berikut :

Option “TwinView” “0″
Option “metamodes” “1280×800 +0+0; 800×600 +0+0; 640×480 +0+0″

Kemudian ubah menjadi

Option “TwinView” “true”
Option “metamodes” “1280×800 1024×768 800×600 640×480″

tambahkan juga opsi berikut

Option “TwinViewOrientation” “Clone”

Sehingga kurang lebih pada bagian Section Screen akan menjadi seperti ini :

Section “Screen”
Identifier “Screen0″
Device “Videocard0″
Monitor “Monitor0″
DefaultDepth 24
Option “TwinView” “true”
Option “metamodes” “1280×800 1024×768 800×600 640×480″
Option “TwinViewOrientation” “Clone”
Option “NoLogo” “True”
SubSection “Display”
Depth 24
Modes “nvidia-auto-select”
EndSubSection
EndSection

Keterangan :
Pada bagian TwinViewOrientation dapat menjadi opsi menarik untuk membelah layar sehingga tampilan pada LCD Laptop dan pada LCD Projector dapat berbeda.

Ada 4 pilihan opsi TwinViewOrientation, yaitu ; LeftOf, RightOf, Above, dan Below

Sedangkan Clone untuk menyatukan layar di projector dan LCD Laptop.

Yang perlu anda perhatikan adalah jika membelah layar menggunakan TwinView, maka layar utama adalah layar yang tertampil di projector. Sehingga layar notebook anda terlihat kosong. Agar muncul di layar notebook anda, caranya sederhana tinggal anda drag jendela aplikasi yang tidak ingin ditampilkan pada LCD projector.

Berikut ini merupakan penjelasan untuk 4 pilihan opsi TwinViewOrientation:

Orientasi LeftOf, berarti seolah-olah projector ada di sebelah kiri laptop, ketika kursor anda geser melewati sebelah kanan layar projector, maka kursor akan muncul di layar laptop.

Orientasi RightOf, kebalikan dari LeftOf, seolah-olah proyektor ada disebelah kanan laptop. Ketika kursor anda geser melewati sebelah kiri layar projector, maka kursor akan muncul ke layar laptop

Orientasi Below, seolah-olah projector ada di bawah laptop

Orientasi Above, seolah-olah projector diatas laptop.

Untuk mengaktifkan twinview, perlu dilakukan proses restart pada desktop manager anda (tekan tombol Ctrl+Alt+Backspace) .

Jika laptop sudah menyala, kemudian kabel LCD projector baru di tancapkan. Kemudian tekan tombol Ctrl+Alt+Backspace untuk merestart desktop manager.

Setelah itu akan muncul tampilan login, disini anda sudah berada di posisi twinview dan Insya ALLAH. Gambar sudah tertampil di projector.

* cara diatas juga dapat digunakan pada distro linux yang lain

Video projector

A video projector takes a video signal and projects the corresponding image on a projection screen using a lens system. All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. Video projectors are widely used for conference room presentations, classroom training, and home theatre applications.

Overview

A video projector, also known as a Digital Projector, may be built into a cabinet with a rear-projection screen (rear-projection TV, or RPTV) to form a single unified display device, now popular for “home theater” applications.

Common display resolutions for a portable projector include SVGA (800×600 pixels), XGA (1024×768 pixels), 720p (1280×720 pixels), and 1080p (1920×1080 pixels).

The cost of a device is not only determined by its resolution, but also by its light output, acoustic noise output, contrast, and other characteristics. While most modern projectors provide sufficient light for a small screen at night or under controlled lighting such as in a basement with no windows[1], a projector with a higher light output (measured in lumens, abbreviated “lm”) is required for a larger screen or a room with a higher amount of ambient light. A rating of 1500 to 2500 ANSI lumens or lower is suitable for smaller screens with controlled lighting or low ambient light.[1][2] Between 2500 and 4000 lm is suitable for medium-sized screens with some ambient light or dimmed light. Over 4000 lm is appropriate for very large screens in a large room with no lighting control (for example, a conference room). Projected image size is important; because the total amount of light does not change, as size increases, brightness decreases. Image sizes are typically measured in linear terms, diagonally, obscuring the fact that larger images require much more light (proportional to the image area, not just the length of a side). Increasing the diagonal measure of the image by 25% reduces the image brightness by 35%; an increase of 41% reduces brightness by half.

Projection technologies

A Zenith 1200 CRT Projector based home theater. Circa 2006.
  • CRT projector using cathode ray tubes. This typically involves a blue, a green, and a red tube. Minimal maintenance is required (unlike projectors that use expensive lamps which must be periodically replaced after they burn out). This is the oldest system and falling out of favor largely because of the bulky cabinet. However, it does provide the largest screen size for a given cost. This also covers three tube home models, which, while bulky, can be moved
  • LCD projector[3] using LCD light gates. This is the simplest system, making it one of the most common and affordable for home theaters and business use. Its most common problem is a visible “screen door” or pixelation effect, although recent advances have minimized this.
  • DLP projector using Texas Instruments’ DLP technology. This uses one, two, or three microfabricated light valves called digital micromirror devices (DMDs). The single- and double-DMD versions use rotating color wheels in time with the mirror refreshes to modulate color. The most common problem with the single- or two-DMD varieties is a visible “rainbow” which some people perceive when moving their eyes. More recent projectors with higher speed (2x or 4x) and otherwise optimised color wheels have lessened this artifact. Systems with 3 DMDs never have this problem, as they display each primary color simultaneously.
  • LCOS projector using Liquid crystal on silicon.
  • D-ILA JVC’s Direct-drive Image Light Amplifier based on LCOS technology.
  • LED Use an array of Light Emitting Diodes as the light source, negating the need for lamp replacement.

Obsolete technologies

  • Eidophor oil-film projectors
  • Talaria oil-film projectors
  • ILA (Light Image Amplifier) light valves
  • Schmidt-CRT, developed by Kloss Video

DIY video projectors

With a growing DIY-community and an increasing interest in low cost devices, some hobbyists have endeavored to build their own projectors from kits, sourced components, or from scratch. Through the internet, the community is now able to obtain plans to construct DIY-video projectors.[4][5] and there is a growing trend toward building them for domestic requirements and classroom use. The DIY-projectors are now being used both in developed countries and in developing countries in the interest of providing education as well as for entertainment purposes.

Lumens Guide

Below is a fast and easy reference for you to use to help determine how bright a projector you need for business, home theater, and house of worship environments.

Key

* Controlled Lighting: If you plan to use your projector in a room where there are no windows, such as a basement, or if you use your projector primarily at night, any of today's projectors will provide a bright image.

Low ambient light Low ambient light: Little to no light entering room.

Some ambient light Some ambient light: Some additional light in room. Slightly dimmed, window blinds leaking some light.

High ambient light Bright ambient light: Windows open during daylight hours, lights that cannot be dimmed like in an open office settings. Bright enough for audience note taking.
