Hi there, Though I've been reading the forums for what seems like years - here's my first post. I cant find anything in the forums (and I notice Zapwizard hasn't divulged what he had in mind for his Monitor in the wireless project) so I'm getting in first! The question is simple enough: "Would a wireless Monitor be possible (i.e. omit the DVI/VGA cable.)" The idea being that it need only be dependant on the length of the mains cable and I loathe cabling. Thus I would like wireless mouse, wireless keyboard, wireless speakers, wireless monitor etc..... As a person who knows the word "electronics" from the "Janet and John read their electricity meter" series. I just wondered if it was possible? My single brain cell reasoned that if the 'D' in "DVI" stood for digital, then that signal could be transmitted. *cough* Before I take this any further I would be grateful for the 'ponderers of all things electrical' to ponder this idea. Hope to hear from you all...
'Video senders' are available - but these only transmit video signals, not VGA signals. I have never seen wireless VGA - I imagine it is only a matter of time, but the bandwidth required would be very high. You could use your TV on your graphics card to send wirelessly to a TV with a video sender, it would be ok for some games but no good for doing real stuff\web browsing on due to the low resolution and accuracy of TV signals. I'm sure somebody will no doubt prove me wrong, but I think its a no-goer at the mo.
short awnser is Yes. Long awnser is not yet, transmission of even PAL-M TV (which is one of the better quality transmisisions, used in the UK) is somthing like 625 lines but only 25fps. The number of vertical pixels, isn't that simple because its anolouge, you can have fun playing around with the nyquest rate and stuff they tried to teach me at a-level but you never realy get much quality. Most people who have tried to connect the sky box to the upstairs room and thought i'll be lasy, and use radio rather than cable, end up running a cable because the quality is so shockingly poor! a quick google pulls up stuff like this: http://www.teleradio.com.sg/remote/remote2.htm yukie, i'll stick with my nice 1920*1200 cable thank you very much!
Well, there's This Thing, if you don't mind running your machine to a TV. I bought one of those video senders (made by RF-Link) on eBay, to send signal from my satellite box to my PC/TV tuner card. It works pretty well, too...much better than I expected, through several walls, over a distance of about 100'. You'll lose quality, but you may be able to live with it.
It currently is possible, however only with projectors Infocus Liteshow. Infocus and 3M make some wireless adapters which cost a hell of a lot of money (~$500). It works over WLAN and transmits a digital video signal, however only to the compatible projectors . You could always try VNC over WLAN, however I doubt it will work that well (at least for movies).
Thanks for the advice all. It seems the common problem for all these devices is the resolution I would want to run my PC - 800x600 is just not an option! I don't watch movies on my PC - I got a 42" Plasma to do that with it mainly used for work and the odd game (actually its the other way round but don't tell the wife!) What I will probably do is to combine the cables from the monitor into a single feed (i.e. two leads wrapped together) it will be thick - but I shouldn't suffer from any shielding problems. All I then need to do is change the case to provide a mains supply - I might even put in a second PSU that has one of those old fashioned pass-through connectors for the monitor - remember them? I havn't yet considered the PC case yet as until I had decided on the peripheral connections I wouldn't know what was to go in it. I dont suppose anyone would know if there is a wireless device I can plug peripherals into such as printer scanner - a look on google only showed wireless network stuff which isn't really what I'm after. The only other option appears to be bluetooth. but my scanner and printer are not bluetooth. Back to the drawing board I guess - this idea is not really taking off! Stu
