Ok have a question about a vga cable.
We install CCTV systems, we just finished a 32 camera install.
We are powering two 42" LCD TV's from one computer with 50ft VGA cable. Quality looks good, no problems with video on both TV's. we did have a problem with computer freezing at first which is fixed now. My boss seemed to think that the video card has to work harder to send video to both TV's with longer cables.
Just wondering how the video card signal works. I figured that the video card sends a set signal to any device that plugs into it. If you have a 5ft or 200ft cable the card wont have to work harder to send a signal, the signal will just drop and you will have poor video. Am i wrong or does the video card detect a device over a longer run an works extra hard. I think i read somewhere that VGA cable peak voltage is at .7. Sorry for this stupid pointless question but it has been bothering me. thanks
2nd question. Does the video card have to work harder to power a 42" TV over a 19" monitor? i have onboard video that hooks up to all my tv's at home.
