I watch ATSC network TV saved in .wtv format. Takes a lot of bandwidth, but looks great. When I tried to watch 1080p compressed format, like from cable, I couldn't stand it. Still pictures were beautiful. Motion artifacts were horrible. A closeup head shot looks featureless initially. As more data gets transmitted, and uncompressed, the lines and pores fill in. Very distracting. You'd think that would be much worse as you try to stuff 4X the data thru the narrow pipe.
I have (by design) one eye the focusses at about 10" and the other at
22". That gives me pretty good vision from about 8" (for close work and reading) to 3 feet or so, good for desk and workbench type stuff. So I only need glasses to drive, and not even really for that.
In my business, it's best to be nearsighted.

If I thought I could stand it, I'd probably agree. I have a lot more problems with closer vision than distance (I have to have two sets of no-line bifocals) but I don't think I could take the difference between the two eyes.
Thanks for the details. A 43" screen in 16:9 would be 37.5" wide. If your eyes were 32" from the center of the screen, the distance to the edges would be 37" away. That's only a 5" change in focus, which probably would not be noticed or produce any eye strain. Running the numbers on my problem, a 50" screen in 16:9 is 43.6" wide. With my eyes 24" away from the screen, the edges would be 32.4" away. That's not a foot difference as I originally guessed, but an 8.4" change which apparently is a problem for my eyes.
I've thought of tweaking the prescription on my glasses to deal with the differences in distances, but haven't bothered to determine exactly what changes would be necessary. Also, I haven't tried CAD on a curved screen, but suspect that it would take me some effort to learn how to deal with the distortion.
Thanks. It seemed rather odd that you were using inches for screen sizes when most everything else in UK is probably metric.

The latency of my new-ish Vizio 43" 4K TV was driving me crazy when I tried it as a second screen for Eagle CAD until I switched to lower latency "game mode". Much better ! At 4K resolution from the graphics card on the laptop, too.
I have it on my desk at work and also works great for engineering reviews. Everybody in the room can read the schematics.
As for watching TV with it, it is a smart TV and so I use it to watch Youtube 4K content sometime, which there is some decent material. It is definitely nicer than 1080P content in my opinion.

Poor guys, in 1998 or so I wrote my own Linux newsreader, basically because there was no FreeAgent for Linux. Added some extra stuff on request by users, and it works fine unchanged since year 2000 or so. It is 100000000x faster (no kidding) than 'browsers' on google groups, has 2 buttons on each screen to set fontsizes, has filters, can use your own text editor, supports multiple news servers, encryption, Russian hac^H^H^H^H^H^H^H^H and has by now acquired a searchable database of many of your scribblings back to 1998.

progress? WHAT progress? Internet html has changed to a zombie advertising network.
It's also common here in India to state screen sizes in inches even though we've been using the metric system for almost as long as the Brits. It may have something to do with tradition and inertia plus American influence but personally, I feel that certain measurements are simply easier to grasp in imperial units. I find it difficult to picture how tall a 178-cm man is without mentally converting it to feet and inches first.
I just bought a (used) raspberry pi and installed pihole, that is a dns ser ver with blacklist/whitelist capability (as backend it uses dnsmasq, that c an do everithing pihole does, but it's kind of difficult to setup, and piho el has a cool web inferface with nice stats).
No more ads :) and as side effect browsing feels a lot faster.

I do have an opinion on this. I am not against HD, but having come from a film TV background we had productions, you know, the set, where EVERYTHING was fake, You know the houses, walls, floors, windows, all painted. On normal resolution you cannot see this at all (those are real artists mind you). But on HD ... If you read a book, say novel, much is build in the brain as phantasy, the characters, what hey look like, it becomes YOUR own version of what the author had in (his) mind. A bit less so in the old normal resolution TV, but still. Then for HD you get that less of it is left to the human imagination, and finally you may as well take your backpack and go for that adventure yourself, as least it will be YOUR experience, so that is what I did. Either that, or the matrix.
Ultra HD for technical stuff, i am sure there is a limit above which it makes no sense, To be at the edge of it you need to be at a distance where you just can or cannot see the individual pixels.
The screen size then becomes immense, you have to walk past it. Makes no sense.
But.. new stuff needs to be sold, so things need to change ever faster if possible, standards should be as incompatible as possible, have as many artefacts as possible, so a next better version can be sold, this accelerates over the years (see how long NTSC lasted), then digital normal resolution, then HD then 4K and 3D and audio the same thing and .. finally the boom explodes and people see they have been conned into an illusion, and out of the really nice fun things, and their money.
I'm longsighted now. I didn't fully appreciate it at the time, but I had excellent eyesight up to the time I was in my 40s. I could easily focus from infinity to perhaps 3 inches and that was a big help in my work.
Now I can still read a newspaper in good daylight but I need glasses for things like soldering and reading in bed.

Yea. Well this is a vector pointing to politics.
I remember working for an US company when little Bush invaded Iraq. I left. I totally disagreed of the hype in that company about the extra sales it created..
These days we see after Trump's visit to his Saudi friends (sure he has business interests there too) Quatar being created as the bad guy in the middle east. Now if he just could invade it or cause some more wars there then the oil price would go up and shale oil from US would bring in some more, and ...
The MIC has full control again of the 'president' he thinks he is the greatest because he sells some more crappy US weapons.
The people are kept in total paranoia and just like in Mc Carthy's days the Russians are the blame for everything, there is a commie under your bed, and..
There is a good and bad, if it is not the US then it will be China, if it was not China then it was Japan, if not then somebody else...
A war machine industry gone bad or mad.
To blame it all on google, like that site you link too, is silly. Sure I use news,google.com sometimes and it actually pointed me to the 5 nm IBM chip article, as it knows I like to read about that, and it also points me to Raspberry clones, and to other stuff, fine, but in the end it is also a short-circuit as it endlessly points to yourself (own interests) keeping the real wider world in the background. So I use many news sources, from many countries, to at least have some idea what is happening.
Trumps tweets? Birds tweet here too, mostly about nests and territorium if I understand the sounds right, cats (make a lot of noise if there is a cat around the garden), food (I feed them bread sometimes). Trump may tweet in agony, in pain, in anger, in self promoting ways, no difference with the birds here. I do have a twitter account but I never used it, if I ever did it was hacked, who knows, maybe by the RUSSIANS, or the CIA. mm, or aliens, . :-)
But these are bad times, , very bad bad bad to use tweet man's words,. is he insane? No he is just a pawn in their game. As was that one with the falsified birth certificate.
Most of it you can follow or could follow on your HD TV, just to get back on topic.
Interesting is that the Russians just presented a new composite airplane a possible alternative to Boeing and Airbus.

As to the other one with the golden hair, if he did stop attacking innocent people that would help stop their counter attacks, always marked as 'acts of terror' a lot more. If US kills a hundred civilians in a country where it has no business, then at the most it is an error, or just collateral damage. Vietnam, Iraq, Afghanistan, Syria, the list is endless, but the war industry, the war machines, the poor US citizens, needs jobs If you cannot export the reason is that people want nice things not bombs, you can force people to buy your shit weapons that is for sure with a gun to their head they will. But US will be defeated by those who have brains (US IQ goes way way down, what do you do, well you fire the professor who did the test right), and make the real weapons. Most of that US crap weapon stuff can be defeated by the lowest of low tech, its is all make believe just like the 4 K TVs have NO added value, on the contrary, just like the inferior Apple high priced crap.
US is doomed, it has nothing the world really wants, and now it loses free speech too.
Yes, then you need to make VERY sure there is no overscan (it can be disabled) and you can map the computer screen to the physical screen 1:1.
I have an older LCD TV with DVI in and a newer one with HDMI etc, but on both of them there is a fixed overscan. When using it with certain computer applications like OSMC (a mediaplayer) there is support in the setup to find the edges of the visible area and confine the user interface to that area, but that is a very coarse user interface only used to control the player. For computer console work this solution is unusable.
It's perfectly comfortable, and it works great. Human vision is very clever; one eye provides the resolution and the other fills in the depth percepion and such. The entire focal range looks sharp. I bought a trial lens set and did experiments; more than this ratio gets weird.
The lens set is great; I do my own eyeglass prescriptions too.

It depends on the distance to the source. Things further away will be more diffuse, but light sources within the room will be focused.
I find watching TV requires appropriate lighting. Most people don't give much thought to it. The best room lighting is a light source behind the TV that lights up the wall. This provides some diffuse room illumination while minimizing reflections on the screen.
Same reason why the US uses mils for PCB design when nearly all the chips are measured in mm. We have been using mils for a long time and haven't been pushed off the dime.
Do you still think of people's weight in stone too? I know my skis are 190 cm which is a tad taller than myself. I don't have a problem with that and I grew up with feet and inches only using metric when doing science and engineering.
I remember talking to a mechanical engineer at an electronics company I worked for and being surprised they were *still* using inches and mils! At one point in a conversation I shortened mm to mil and we both became enormously confused. I don't use the term micron because I can never remember if that is metric or imperial!
