jameskap 0 Posted January 6, 2009 Hi, Can anyone assist with the following problem. I have connected an av to vga converter to a computer screen to display security cameras, The problem is the LG monitor goes automatically into power saving mode when powering up the monitor and you have to press the source button to get it to see the picture from the cameras and switch on again, once the screen is on it will be fine but switch the monitoir off and then on again you have to press the source button to get the picture back (this can be quite iritating if you switch the monitor off every night and back on during the day), this may not seem like a big deal for us tech guys but for the end user who doesnt know anything i can see this will be a problem. Any suggestion and help would be appreciated Share this post Link to post Share on other sites
scorpion 0 Posted January 7, 2009 What kind of LG monitor? Can it be controlled by a remote control? If so can you get a "smart" remote, and teach it a macro, or a sequence of commands? Turn on monitor, select correct video source. For a bigger project you could use something like this: http://www.xantech.com/Controls/ControllersSwitches/ControllersSwitchers/MAC1/ Manual PDF http://www.xantech.com/files/manuals/30_MAC1.pdf What do you think?

jameskap 0 Posted January 7, 2009 HI Scorpion Thank for the reply, unfortunatley the monitor does not have IR, it is a computer monitor LG1719s -BN Stricltly d-sub and power in connections only with the vga connecter in line of the d sub cable. Thanks for the great solution, Mac controller 1 switch, i wasnt even aware such things existed!! I will definitley keep this in mind when next time using IR, as no doubt this is a life saver in a situation like that. Thanks once again cheers Share this post Link to post Share on other sites
scorpion 0 Posted January 7, 2009 Planetariums love those. Can you imagine turning on all of those amps, projectors, ect, ect by hand? Yikes! I assumed you had a regular monitor as you said that you had a source button. I assumed that this gave you composite video, component video, and other options for video input.

jameskap 0 Posted January 7, 2009 Hi, yes i can see that being very helpfull indeed. Sorry i should of mentioned that the source button is actually on the vga convertes and not on the monitoir itself. Cheers Share this post Link to post Share on other sites
Soundy 1 Posted January 7, 2009 What make/model of converter is it? Maybe a different converter would be better - sounds like it's not feeding the monitor the proper signals to keep it awake. I've used a couple of these successfully - the cheapie DVRs I mentioned in this thread used an internal composite-to-VGA adapter that was problematic in some models, and our supplier/contractor's solution was to have us remove the card and use an external converter. And no, I don't remember what make/model that was either But in any case, it did work fine with a standard cheapie VGA LCD. Share this post Link to post Share on other sites
jameskap 0 Posted January 7, 2009 Hi Soundy the converter is an external converter. i think i will check a few different models and see what happens! Share this post Link to post Share on other sites
jeromephone 6 Posted January 10, 2009 We just went through the same thing and we were using LG monitors. The video converter does make a big difference we looked at three differnt ones side by side and you can see the difference. We did not have any problems with the monitors not staying on once we hooked up the converters. Share this post Link to post Share on other sites
jameskap 0 Posted January 10, 2009 Hi Jerome thanks for feedback, i now begin to believe it is the VGA converter at fault and had seen the fault occuring whilst on site the other day, During any given time picture would just intermittently drop off the monitor not return and the screen would go into power save mode, you would then physically have to press the source button on the vga converter to get the monitor to see the picture again, I then started doing some fault finding and found that if the camera is connected next to the converter (eliminating the coax cabling run) that the monitor would work 100% and even switch the monitor off and on again, the picture would return, I suspect that the Vga converter is too sensitive to the fluctuating signal level sent down the line of the coax that the picture just drops out on the monitor and does funny things, If i connect the cabling run and camera to an av input monitor there are no problems at all, and works 100%, Therefore i suspect the converter to be "fussy" Can you possibly give me the make/s of vga converter that works best for you? Thanks Share this post Link to post Share on other sites
jeromephone 6 Posted January 11, 2009 for a low cost one check out PI MFg they sell a cheap converter that works well I think it is a shineybow 3860 Share this post Link to post Share on other sites
