Television notes

last update:

Presently we have a number of Samsung televisions. These are notes on them as I recognize the need.

Samsung 75" 4K Crystal whatever television

I was disappointed by there only being 2 HDMI ports, but I have discovered this Orei UHD-402 matrix switch that will multiply the possible HDMI inputs (to 4) and, if that weren't enough joy, permit me to run a second screen with the same or different content on my television. This is something to think about.

My older Samsung 55" television had at least one more HDMI connection than this. I replaced that one with this new 75".

This may be my television's backplane. I'm not going to importune myself by lifting this thing off my livingroom wall just to take a picture.

Review and features...

This isn't exactly the television I have, but it's close (mine's bigger).

Samsung TU690T 4K Crystal UHD TV

Refresh at 120Hz versus 60Hz...

A question on refresh speed. My nephew can be thanked for this answer.

"I've been operating under the possibly mistaken assumption that higher rates of screen refresh are crucial for:

"I have considered then that 120Hz is the minimum acceptable rate for large-screen televisions, but that rate is never/rarely seen on smaller screens (under about 46").

"What can you tell me about this? For example, what am I losing watching Blu-ray on 19" 60Hz LEDs vs. my 47" 120Hz LED? If I bought a mid-sized unit, is that still going to be the same experience as on my 19" TVs?"


"The 120 Hz refresh rate is most often taken advantage of by Blu-ray action movies. It provides a smoother experience and is often seen by most people to be slightly nicer on the eyes when staring at the screen for long periods of time. I admit I can tell a difference between the two, but I will also admit it is very minute. I have a 60Hz 40" Samsung and it works beautifully. The 120Hz refresh rate is more of a luxury than any kind of necessity. You probably won't notice much of a difference. It might as be interesting to note that 240Hz is often seen as too high giving a "fake" look to the video.

"If you're willing to spend the extra money and get a really nice TV, I would recommend 120Hz, but 60Hz on a 40" TV should be fine. I doubt you'd notice much difference by going to 120Hz.

"Most TVs are only 120Hz at higher screen size because the manufacturer think that if a consumer is going to spend the money to get something that big, he probably doesn't mind spending the money to get a higher refresh rate. At smaller than 48", the cost-to-who-cares ratio is too low to make it worth making a 120Hz screen."
