I have a 3 year old HP laptop that would serve.
HOW do I plug it into the tve?
Probably will. IF it has an HDMI output port... Looks kinda like a USB port, but USB won't fit it.
It may not have one... In which case, I would be looking for a desktop machine to do the trick... Because it will either have HDMI or it can be added on a vid card.
You can maybe mcgyver it otherwise with the laptop, but HDMI is what is best. A DVI slot would be ok, but not as mo'bedda... And I can near bet there is no DVI port on that laptop. There is also HDMI by USB converters, but they suck.
Do you have an English language version of the above?
You will need network at the computer - From your router to yhe TV computer... Wired (cat5 cable) would be best - Bigger badder transmission rate... But wireless (which your laptop already has) will likely be fine. If it is 3 yrs old it is likely N or AC already (Types of wireless... AC is newest, then N, and G, which you would not like) So you are likely good on that.
In addition to the other cables already mentioned? WHERE does all this stuff plug into my laptop?
That is why an HDMI port is king... Just the one cable would be needed... It shoves both the video and the sound into the TV. You likely do not need a network wire, as the laptop is probably already rigged to get to internet wirelessly (WIFI). If you can get on the internet with it... Surfing with a browser I mean, you are already connected to network.
And the wireless keyboard will have a little USB thingy you will plug in, and that's it.
So LIKELY connections:
You need to see if it has a HDMI port.
You have it connected to network already.
And you need to plug in a USB connector for the wireless keyboard.
What's wrong with my tv speakers?
Probably alright. I got mine hooked through an old house amp and monster old house speakers (4 of them) because I like good sound... And mine is a media center... My music library is onboard that computer, and I will often stream music on the Yootoob... I need not go to far into the 'turn it up' mentality of that.
