Hi
I recently went to a new venue and hooked up two laptops to my Kramer VP-730 (Presentation Switcher/Scaler). Output of that was connected to a pair of Panasonic PT-VX501 projectors.
Problem: No matter what we did, the image size differed when switching between Laptops.
Troubleshooting:
- Setting both Laptop's output to 1024*768
- Hitting 'Auto-Image' within Kramer's Menu
- Hitting 'Reset to VGA' on the Kramer
- Hitting 'Auto-Image' within the Projector's menu
- Changing VGA cables.
- Doing a Factory Reset of the Kramer.
I finally removed the VP-730 and replaced it with an older Kramer VP-724
The difference between the screen sizes from both laptops very much improved. It was small enough to run the show, but someone with an eagle-eye could have spotted it.
Question 1: What are the best practices to get bug free output over VGA? (Assume no control over the laptops in use)
Question 2: Is Bug free projection with various sources and multiple destinations (for example, a second set of Projectors/TVs 40m down the room) possible with VGA cabling? I have used an unbranded active Balun over VGA which worked well for 3 days, but on the 4th day it randomly had some 'snow' in the image!
Question 3: What do you Pros use for high-wire events...VGA or some other system.
Much thanks in advance!
