VGA balun
Answer
We offer two types of VGA balun: passive and active !
Our Passive VGA Balun offers an ideal link between data output equipment and VGA monitors using 4-pair Category 5 shielded cabling, eliminating the cost and clutter associated with heavier VGA cables.
Designed for use with computers, LCD monitors and multimedia projectors, the Lemar VGA Balun is perfect for classrooms, public presentations and video information systems.
For better quality performance always use this product in conjunction with shielded cabling.
Our Active VGA balun supports a local monitor and a remote monitor via Cat5 or better cabling. Each set includes one transmitter and one receiver. The active model is good for high resolution
This solution is really pratical if you want to view on a local monitor a VGA signal and at the same time send the VGA signal to a remote VGA monitor or projector, eg in education or shop displays where the distances involved are greater.
Contrast and brightness adjustment are included for a perfect setup. Both the transmitter and receiver are housed in a robust SPCC with black painting case. These active VGA baluns work in conjunction with laptops, PCs, flat-screen LCD monitors and multimedia projectors.
The Active VGA resolution/distance are:
640*480 (VGA) > 180m
800*600 (SVGA) > 150m
1024*768 (XGA) > 130m
1280*1028 (SXGA) > 100m
1600*1200 (UXGA) > 80m
1920*1440 > 70m

Answer
Active VGA supports high resolution, up to 1920x1440. The Passive VGA goes only up to 1280x1024 pixels.
Then, the distances are as below:
Passive VGA:
137m (450ft) with VGA resolution 640x480 pixels
107m (350ft) with SVGA resolution 800x600 pixels
76m (250ft) with XGA resolution 1024x768 pixels
61m (200ft) with SXGA resolution 1280x1024 pixels
Active VGA:
180m (591ft) with VGA resolution 640x480
150m (493ft) with SVGA resolution 800x600
130m (427ft) with XGA resolution 1024x768
100m (329ft) with SXGA resolution 1280x1028
80m (263ft) with UXGA resolution 1600x1200
70m (230ft) with resolution 1920x1440
