Sir Cryalot #4 "Dehát, kell az a pofáraesés vr-rel is."
“I’ve been working with helmet mounted displays in military flight simulation for several decades – I am an expert in the field… IMHO – these devices should be banned – but that may not be necessary because after the first wave of early adopters I think it’ll go the way of 3D televisions. But that’s just my opinion. Let me explain why.
"Everyone thinks these things are new and revolutionary…but they really aren’t. All that’s happened is that they dropped in price from $80,000 to $500…and many corners have been cut along the way. There are several claims that the nausea problem has either been fixed, or will soon be fixed, or that application design can be used to work around the problem.
The claims that it’s been fixed are based on the theory that the nausea is caused by latency/lag in the system, or by low-resolution displays or by inaccurate head motion tracking…all of which can (and are) being fixed by obvious improvements to the system. Sadly, the $80,000 googles we made for the US military had less latency, higher resolution displays, and more accurate head tracking than any of the current round of civilian VR goggles…and they definitely made people sick – so this seems unlikely.
The problem is that the people who make those claims are either ignorant (or are deliberately ignoring) the evidence collected over 20 years of flight simulation experience with VR goggles (only we called them ‘Helmet Mounted Displays’ – HMD’s – and what we did was called ‘simulation’ and not ‘virtual reality’). Worse still, there is strong research evidence that the harm they cause extends for as much as 8 hours AFTER you stop using the goggles. Considerable disorientation after prolonged exposure to VR. The US military recommends that users avoid flying or driving for up to 24 hours,” wrote Baker on Quora." -
Sir Cryalot #3 Japánok 2006-ban külön csináltak sebészeknek olyan displayt ami színes is mégsincs subpixel, se vr-nek nem hívták, se felhajtást nem gerjesztettek köré,
http://onlinelibrary.wiley.com/doi/10.1889/1.2433326/abstract
amit meg ezek a vr cégek csinálnak most, hogy "kitöltik" a pixelek közét valami szétkenegetéssel, az + az évszázad eddigi vicce display ügyben (és hát , szar).
Dehát, kell az a pofáraesés vr-rel is.

A cikkel nincs gondom, csak tartalmilag szokott a Samsung kicsit lódítani.
4K felbontás az 3840x2160, vagyis 8 294 400 pixel
Ergo: 24 883 200 subpixel.
Samsung pentile matrixos megoldása 1 pixelt nem 3 (vagyis RGB), hanem csak 2 subpixelből számol (egy RG vagy a mellette levő BG pixelt)
Vagyis az csak 16 588 800 subpixel összesen.
Ha az ő kijelzőjükön is 3 subpixelt számolnánk 1 pixelnek, akkor az már egyből csak 5 529 600 pixelnek felelne meg.
Na és azért 5,5 és 8,3 megapixel között van különbség...
Ez persze nem azt jelenti, hogy pentile matrix, mint technológia rossz lenne.
Csak a pixelszámozása csalós egy pöttyet.... -
Jackal #1 Szép magyaros lett a cím, a google fordító se csinálhatta volna jobban. oh wait...
