Nobody gets dinged for asking questions here, and I'm glad you chose our forum to interact in.
There isn't a wireless way to transmit a signal built into the TV, and I don't think there's one built into the computer either.
However, there may be a push-box type solution from a third party company that you can connect the comptuer to (and of course a receiver on the TV that you'd connect), but I don't have any recommendations on manufacturers or products, nor do I know what the quality would be. Other forum members with experiences might be able to assist there.
There is wireless DLNA, but that's a feature for specific movie and picture types, but from what I read in your post, you're looking to run your entire desktop on the screen.
I hope that I do not offend anyone by asking a question that has already been answered but I have searched all over the net and these forums trying to find out how to do this with no luck. I have seen many posts but they seem to be looking for how to set up a network to their TV or how to hook up a laptop with wires. The question that I have is:
What do I have to do to be able to use my laptop on my Samsung TV so that I can surf the net and open up any documents that I have on my laptop. Essentially, to be able to sit back away from the TV and use its screen while working on my laptop, but without an HDMI cable attached.
I am able to connect successfully with an HDMI cable (which is what I am using now while typing this post) and I am also able to access my desktop and laptops media via my wireless network and DLNA. I just am looking for answers on how I can use the beautiful Samsung screen and my laptop while I am sitting away from the TV without a 10' HDMI cable strewn across the floor. With a 3 year old and 2 pugs, there is way too much that can go wrong with that setup 9)
Here are my specs in case this will be important in formulating an answer:
HDMI, 1080p, 240Hz, ...
Dell Inspiron 1525
HDMI, wireless, Bluetooth, ...
Linksys WRT54G2 Wireless G (connected to laptop wirelessly and to TV with an Ethernet cable. Modem and router are two shelves below the TV.)
DLNA connects media from desktop and laptop accessed via the "source" button on remote.
I hope this post is not too long. I am hoping to give as much information as possible towards this.
Thank you all for past answers and any help on this matter!
