Also some people have already had noticeable lag on the screen for the update of the mouse position when using 4K monitors at 30hz (caused by double-buffering in combination with low refresh rates) - now increase the latency and that would cause people to complain that it is unusable.

If compression/decompression were such a cheap thing to make standard, why is there not compression/decompression in every networks switch and network card? My networking using the standard low speed 1GBit for the local network is rather slow. For that matter how about the sata controller and hard drives? Or why not compress between the CPU and PCIe bus itself? If compression were cheap then all those could use it.

I have a rather old mac pro, and the mplayerx I believe does not use the GPU and probably is not implemented to use multiple threads, and it cannot play 1080p without a video/sound sync problem (the internal player works fine - not sure if it is more efficient or uses the GPUs I have installed).

So instead of a little bit more expensive cable, you want the monitor to consume more energy and have to basically put a fairly powerful CPU/GPU inside the monitor. Both of those solutions increase the base cost of the monitor way more than the more expensive cable, and increase the ongoing power consumption costs of the monitor. That is really a better solution? For a select few that want to put their computer 20m away then just use a display with a thunderbolt port and use an optical cable (yes it is a bit more cost, but you are going to pay for it one way or another and it is best not to bog down 99% of the people that have their computer at the desk near the computer.

Comment: Re:Multilink? (Score 2) 94

The first monitors out that were higher bandwidth requirements supported multiple cables, but consumers rejected that and preferred the displayport single cable solution. The standards organizations are just trying to make sure they can support what consumers generally want.

Comment: 13/15" laptops have had the equivalent resolution (Score 1) 94

I did not hear much discussion about how HD on a 13/15 inch laptop was overkill when it became standard more than a decade ago.

I use a 40 HD monitor as my main display, but I would definitely notice the difference the difference in having a 4K monitor (when I run the iPhone simulator - the resolution is high enough that it will not fit on the screen). A 40 inch screen is 600+% larger than that 15 inch laptop. So to keep the real resolution (pixel size) the same for a 40" monitor you would require 5K.
In addition I use multiple monitors (4), and displayport monitors have the ability to be chained on the same connection -- which would allow me to get a laptop (later this year when Skylake is out) and have 3 x 40" monitors attached using this standard.

Comment: Difference between TV and monitor use cases. (Score 1) 94

4K and 8K are not as much of a benefit to TV as it is to monitors. When pictures are in motion, the higher your perception of image detail is not as noticeable by ones eyes. As a monitor for a work environment where images are not motion pictures, 4K and 8K are very easily noticeable. It will give the image more depth and you will be able to use the extra workspace on a 40+ monitor. If you shrink down the image it is more recognizable than if you display the same image in the same size on a HD monitor. You have both peripheral vision for dashboard use, and a neck to move back and forth to different documents/ images / text displayed on a larger workspace -- but when you are looking at something you are focusing on a small area on the monitor. If the extra resolution were not usable to provide extra depth to your pictures, cameras would not be pushing up to 50Mpixel resolution.

Comment: 8K monitor = 4 x 4K monitors (Score 1) 94

People have been focusing on 8K monitor actually (7680 x 4320 at 60hz) as if this cable is hard wired to only support a specific config. It supports multiple MST configurations, which means the ability to configure panels into one screen - using multi streams, or multiple monitors with multiple streams. This means it has more than enough support to drive 3 x 4K monitors using this cable, which I personally could easily put to work (I have 4 monitors of various HD resolutions and sizes). I would like having 3 x 40 inch 4K monitors on my desktop. It would be great if I could use a laptop and have the same setup (though there is a limitation on that due to processor restrictions right now - though Skylake looks like it will have enough power to do it). Now if they were able to do a cockpit type monitor that curves around as one monitor with 23040 x 4320 @ 60 hz that would be great to (but hard to move around :o ). I have seen some people complaining that 7680 x 4320 is not 8K (8000 x 4000) but if it has the bandwidth for the first, it has the bandwidth for the second configuration (less pixels). They seem to fail that the cable is not for a specific resolution but to support higher bandwidth monitors going forward.

Dam it got rid of the new lines. (I will try typing). Service Menu Code For Samsung TV: There are many codes available for accessing service menu in various Samsung TV models.

You can try following codes one by one until you get access to service menu:

Mute + 1 + 8 + 2 + Power
Display/Info + Menu + Mute + Power
Display/Info + P.STD + Mute + Power
P.STD + Help + Sleep + Power
P.STD + Menu + Sleep + Power
Sleep + P.STD + Mute + Power
You can press Channel Up/Down buttons to navigate between available options. To change their values, press Volume Up/Down buttons.
Be careful about certain options - you can change things that could do nasty things to your TV.

It is usually different for different model groups. For samsung it is probably one of the following: "Service Menu Code For Samsung TV: There are many codes available for accessing service menu in various Samsung TV models. You can try following codes one by one until you get access to service menu: First power off your TV using the remote, then press following buttons quickly on the remote: Mute + 1 + 8 + 2 + Power Display/Info + Menu + Mute + Power Display/Info + P.STD + Mute + Power P.STD + Help + Sleep + Power P.STD + Menu + Sleep + Power Sleep + P.STD + Mute + Power You can press Channel Up/Down buttons to navigate between available options.

For each "SMART" TV they typically have the same model with none of the "SMART" features for cheaper. I don't need or want any of the smart features, so I never buy Samsung's SMART TVs but I have bought the non-SMART equivalent. Many people seem to think ahh a "SMART" brand TV for more money and don't realize that they are paying for "SMART" features that they never had plans to use. SMART just sounds like a better TV.....

Comment: Safer never to use GOTO (Score 1) 677

If you feel you "need" to use GOTO to make things easier, then you should take a second look at your code and invest a little time figuring out how best to reorganize your code. GOTO gives an easy out for lazy programmers who don't want to invest the time to give a little thought on how they programmed themselves into said box. In my 25 years of software development, I have never found a situation where the use of GOTO would produce better code than putting a little thought into your code.
