Not only is this not impossible, but products that do this exist. DisplayPort (and therefore mini-displayport and thunderbolt) supports DVI and HDMI output over passive adapters using Dual-mode DisplayPort. Dual-mode DisplayPort only supports single-link DVI or HDMI. Single-link DVI is limited to 1900x1200, but single-link HDMI can go up to 2560x1600@60Hz ...

The MacBook Air and similar MacBooks do not provide HDMI inputs, only outputs. Although there is a device that will allow you input HDMI if you are willing to pay for it. (Usually fairly expensive) Something like this is what you are looking for: www.hauppauge.com/site/products/data_hdpvr.html

The problem is most probably that the MacBook is closed while connected to the external display and the antennas aren't transmitting right. Try opening the MacBook and the Wi-Fi problem should be fixed.

I have solved this problem with the help of telephone support. Initially I was disheartened after reading all that has been written in this particular article comments section, but luckily I managed to crack this. I had earlier used a samsung with the mac mini, and straight out of the box, it matched with the samsung. It appears that this leaves the mac ...

The MBA GPU may be limited to a single external monitor, but the USB to HDMI requires a driver installed on the MBA and that video/image is not using the GPU, it's using the CPU. So the limit is bypassed. Now it might be more complicated than this, but I think is this the basic premise. Be aware that for fast moving videos or games the USB connected display ...

I don't know if you can prevent it, but I use an app called Stay by Cordless Dog ($15, free trial), which keeps windows in place between display configuration changes.

Go into the menu on your external monitor. If there's an option that allows one device to toggle the power on the other via HDMI, make sure this is deselected (honestly, I don't think this will have an effect as your laptop is doing the driving, but for the sake of troubleshooting...). I too use an MBP Retina with external monitor (via HDMI). If I shut off ...

Yes - there are quite a few docks to connect one cable to a Mac and have gigabit ethernet as well as HDMI out (and some even support 4K resolution on the HDMI).

I think you have to get them separately. Have you thought about using an ethernet to usb adapter? Those are cheap. Then again, the ethernet to thunderbolt from Apple isn't bad ($30). USB 2.0 may have (although it would be unlikely) a speed bottleneck. Ignoring this, there are many generic adapters for ethernet to USB. I'd make the choice based on which port ...

You must check your sound settings thoroughly but I think this may be a default setting unfortunately! You may just have to ignore it and keep your MacBook open. 😔
