Hinweis der Redaktion
- When setting up the CORIOmaster width = image width, height = image height. Bezel might have different dimensions on each side; left, right, top, and bottom. Overall width and height includes the image size plus the bezel size.
- Use EnTech – MonInfo software to show the screen native resolution of a display. Discuss how monitors have many resolutions but you want the native resolution so you do not use the scaler in the monitor. Our scaler is better.
- In the c2-2655, c2-2755, c2-2855, moving the image is found in the menu item – Place. I would have thought position.
- CORIOgrapher allows a workspace of 16,000 by 16,000 pixels.
- When setting edge blending, one projector will output a red line and a green line for the blend. The other projector will output a green line and red line to match the other projector. When the two projectors are set properly, the red and green lines will add to create a yellow line.
- It is best to set up your destinations first. This ensures the you can see what you are doing. It also sets your output resolution that matches your monitor native EDID resolution. tvONE products have better scalers than your display device. Let CORIO do the scaling, not your monitor or projector. Set your sources next. Again, you want to have the highest quality inputs as possible. When you put a source on the canvas, the source now becomes a window.. Windows are containers that can switch sources. This source switching is very powerful especially when working with presets. The canvas is where you do your work. As an any artist, you need something to create your master pieces. The canvas is where you work.
