Using 1 computer in two rooms (not simultaneous)

[Mathsnerds]

Hello,

 

I've had a concept in my mind for some time now and I know its been done before.

 

How can you use 1 computer in two rooms?

 

I have my main computer situated 10-15m away from the study. I use it to game with my friends and  to develop websites and content.

Therefore, I would like to have a simple and latency-free way to use it in the study instead of the room its in as well. I wouldn't be using them simultaneously so I considered a long HDMI and USB hub but I cant run a cable to it. 

There is a single network connection in the room it is currently in which isn't optimal.

 

Any advice on where to go next?

just do as you thought run a long display and usb cable. Use a powered hub for USB and you should be all set.

If over the network is the only interface you can use, then your option are remote-in tools like VNC or TeamViewer. These can introduce some lag though.

 

Otherwise a KVM switch would be more ideal here.

Yeah I think I'll look into doing this but It might be difficult to get it through the walls. Is there anything like a power-line adaptor for displays?

I've tried VNC and TeamViewer and dont really like the premise of using an online account to connect them. Also VNC is played unless you want to use their remote cloud services which makes me feel unconfortable.

 

I'll look into KVM switches...

 

Thanks @GDDRRiley and @M.Yurizaki

there is wireless ones but they are a lot and don't look to be very polished

Yeah ive unfortunately had someone buy them before D:

I found a 15m amplified HDMI cable... They are all very expensive AUD$90 and upwards. Also I have NO direct line of sight to the room. 

 

It's a shame that I don't have 2 ethernet connectors in the room because I could use a HDMI over IP or HDMI over cat6... Is there anything else I can do?

Ethernet only uses half the conductors on the cable for 100MBit, you could split it at either end for two cables.

Really? How would the wire be configured for such a cable?

There's a million different ways to go about this.  It all depends on what you are willing/able to do.

 

Can you move your PC so that it's equidistant? If so, you can mitigate a long cable run for two shorter ones for display. 

 

Wireless Keyboard and Mouse should be fine for your needs, right?

 

15 meters really isn't that far.  You can run cables under carpet, over doorways, or through walls without cutting if you need to.

Well after 20 minutes of writing how to do it, looking for a picture and finding one that explains it much better.

Wow thanks I couldn't find this myself so this has really helped me out for another project of mine.

Unfortunately I cant move my PC to be equidistant. Wireless peripherals might be possible but im sceptical as theres about 4 walls in between the rooms, plug a cupboard and a long hallway. I could give it a shot though, would definitely save me heaps of trouble.

A 1080p HDMI signals take around 3.5 Gbit/s of data. Dual 100 Mbit/s ethernet isn't going to be nearly enough.

 

There aren't any powerline adapters for displays, as you may note even powerline adapters for ethernet typically do not support Gigabit speeds... Displays require huge amounts of data, if you can't connect it with a dedicated display cable then there are no wireless solutions or methods of routing it through other cable types without significant framerate and/or quality loss. There is just nothing equivalent in terms of data throughput capability. If we could get good quality HD video through something as simple as an ethernet cable we probably wouldn't have ever started using HDMI cables in the first place.
