Hi to all. I wanted to connect my PC to my smart tv (mostly for gaming). The problem is that the distance between my computer and the TV is of about 20 meters. As long HDMI cables tend to give problems, I was thinking on using an ethernet cable with two HDMI-RJ45 adapters like these.

My questions are:

-Will there be any lag/delay? (My purpose is gaming and I cannot achieve that with a big delay)
-Will the image be sent with a framerate of 60fps at 1080p or will the framerate be capped with this kind of connection?
-¿Can it be used for sending a 3d signal? (I want to play with Tridef/Nvidia 3D TV Play drivers for viewing it with the 3d glasses included with my Samsung Smart TV)
-Will there be any loss of quality in comparison to the standard HDMI connection?

Thanks in advanced.

If you're sitting in front of the TV, and the PC is 20 meters away, how are you controlling the PC?

@USAFRet I have in mind to use a wireless USB gamepad.

Yeah, look into control. There's probably a lot more lag in a long bluetooth link (if you can even get it to pair) than in the cable.

I don't know if you'll be able to get the 120Hz needed for 3D traffic over the Cat5/6 link. That might be pushing it.

However, 1080p60 at least should work fine, and there shouldn't be any degradation like there is with e.g. DisplayLink. They're dumb media converters; they aren't mangling the signal.

Also, just for the sake of correctness, this isn't Ethernet. It's HDBaseT, which just happens to use the same physical cable.

Unless you have specific, tested, confirmation that your chosen controller will work at that distance, I have my doubts.
Even then...wireless connections are very touchy. What works in my house may not work in your house. At the same 'distance'.

Yes, you're right. I don't think that my gamepad will work at that range, what I have in mind is to bring the USB receptor closely to the TV with an USB extender.

One thing more: I'm new to this forum, how can I quote someone?

Pull the ="<user>" section. For some reason they removed that, so the only way to quote is either the button or an:

Even then. The specifications for USB is pretty much limited to 5 meters. Still leaving 15 meters of wireless distance.
Yes, people sell longer ones. Do they actually work? Unknown.

Thanks to both of you. I think I will try first to use a normal HDMI cable to see if it works. According to the USB gamepad, I have tested the wireless conection from my couch to my computer and it seems to work without needing any extender. However, the connection is a bit unstable so I will buy one of 5m.

Again, thanks for the info. :)
