RGB / DVI Converter
RGB/EGA/CGA/MDA to DVI/VGA
|
The performance of a CRT monitor is determined by two main parameters: the signal type - VGA, RGB, FBAS, SVHS, ... and the synchronization frequencies - HSYNC and VSYNC.
To display an RGB signal, standard VGA-screens need Red, Green and Blue as analogue signals with 0.7Vpp and synchronization signals as TTL-signals in a range for HSYNC of 30kHz up to more than 100kHz and for VSYNC of 50Hz up to more than 120Hz.
The use of TFT-Monitors with RGB or EGA signals can be difficult: these monitors must digitize the incoming video signals and display the result. To do this, the monitor needs to be given the exact count of pixels per line and the phase of the pixels. Note: many flat screens only operate with the so-called VESA resolutions. Screens may not necessarily recognize the resolution at the output of the RGB to VGA converter. Please contact your screen manufacturer, to determine whether the display is able to show the generated resolution/sync-frequency.
The RGB to DVI/VGA Converter displays the signals of a RGB or EGA source in a format that can be shown on a traditional CRT with VGA connector as well as on a flat screen with DVI connector.
NEW: now supporting EGA!
The device digitizes the incoming video signals and stores them in an internal video memory. From there they are displayed in a compatible, user selectable, format: 640x480, 800x600, 1024x768 or 1280x1024, with 75Hz or 60Hz refresh rate.
Before displaying, the picture can be stretched to fit to the screen size: 1:1 in a black box; fully fitting to the screen size; fitting one dimension with the other scaled appropriately; or at a fixed 2:1 stretch factor.
Design:
- Supporting the traditional VGA Standard, and new DVI Standard
- Desktop Devices - Rack Mount options (19”): Mount up to 4 devices in 19”/1U. This saves expensive rack space .
- parts delivered: RGB to DVI Converter, RGB(S) to DVI-I Adaptor, international p.s.u., DVI-I to VGA Adaptor
- Resolution: from 512x256 up to 1280x1024 and respectively HSYNC from 15kHz ... 85kHz
- Input Signals: RGB, RGBS, RGBHV, CGA, MDA und EGA
- Output Signals: VGA or DVI auto sensing
- Scaling:
-Original in black box 1:1
-format fitting
-proportional fitting
-fixed stretch factor 2:1
