Multiple system atrophy (MSA) is a progressive neurodegenerative disorder characterized by a combination of symptoms that affect both the autonomic nervous system (the part of the nervous system that controls involuntary action such as blood pressure or digestion) and movement.aTscan can assess the dopamine transporter in a part of the brain called the striatum and can help physicians determine if the condition is caused by a dopamine system disorder; however this test cannot differentiate between MSA and Parkinsonâs disease.
The maximum length you can run an HDMI cable depends mostly on the power output of the device, so it varies. It typically tops out at 50 feet, though, and anything beyond that requires some type of extender.
You may have this problem at lengths over 10 or 15 feet; it depends on the cable. There is a new designation for 4K-ready cables, called HDMI Premium, which you may want to look for if you are planning on 4K. Even 4K link speeds can be deceiving, because the link speed of 4K30 is half that of 4K60.
