Philips 43PUx4900 as a PC monitor

This post is going to describe an UltraHD  (4k) TV being used as a computer monitor (so this is NOT an audio-video signal receiver).
The screen has 43 inches and native resolution of 3840(×3)x2160 and can do 60Hz. As far as I can tell, this is an RGB matrix with every pixel made of 3 subpixels (r,g,b).
The resolution is too high - 50" screen would be better for UltraHD.
There is no 3D display (would be nice for 3D games).
Screen refresh is good. If you are already fooled by manufacturers then this needs some explanation. Manufacturers would talk about 1600Hz or more refresh rate - but it is a lie as screen is divided into pieces and they are adding values. This screen is told to be 400Hz and it can do full 100Hz what is great (currently best TV's can do up to 200Hz). That is like if you had 4 kids and every was 2 years old... and you were saying that you have 1 child who is 8 years old (as 4x2=8). Another lie is... what is 1Hz. In the past manufacturers provided info how long it would take to switch a single point on the screen from white to black and to white back again. Later on they cheated giving gray-to-gray-to-gray. So this value is saying nothing and it is usually measured in milliseconds (ms). They just wanted to fool people with crazy numbers.
Let's go with the price and features. It costs around $400 so is quite cheap as for 43" UltraHD display. Has no smartTV nor other crap. Like I already mentioned - I'm not considering this as a TV. And "smartTV" can be made by... connecting this to a computer with better results. Although you loose a feature of using 1 remote to control both the "power on" and "smart features".

To use the screen you might connect it using HDMI and optionally ARC (something to connect audio FROM the display). Probably better is to connect PC directly to the speakers.
It is pointless to buy extra expensive gold plated cables. The HDMI signal is digital thus (unless you have way over 5m cable) any cable should be just fine. And there is no such thing as "HDMI 2.0 cable" - just an ordinary cable that costs $2 but has "HDMI certificate sticker".

Annoying features.
The screen has "micro dimming" feature. It can improve quality of a movie but leads to anger only when used with a pc as your screen brightness goes crazy. To turn it off... switch display mode to "picture".
Also remember to avoid static pictures or the screen on without signal - it should not be a big deal but might burn some "ghost image" over the screen.
Windows 10 with this screen does nasty things thanks to its builtin scaling (which cannot be disabled) as "clear type" makes fonts unreadable - just turn font smoothing off.

It has 3 HDMI ports, is quite thick as for LCD and has USB port. More ports are there - refer to Philips docs.

Overall it looks great from 30 cm distance. I'd like to use 50" or more as an UltraHD PC monitor.

HP Elite 8200 CMT and Windows 10

For several days already I'm trying to update my OS to windows 10. Several showstoppers hit me in my face though.
First the existing OS for upgrade. PC came with dvd's for manufacturer modified bloatware filled windows 7 in either 32 or 64 bit configuration. I'm using the 64 bit version (over 4GB of RAM in use) so it is 4 DVD's load that restores within 4+ hours wiping out entire system's content.
Then you realize that it restored an MBR image. So HDD over 2TiB might be an issue. Change to (U)EFI boot is not trivial but possible.
Then the upgrade to W10. It doesn't work with this modified EFI dual boot mode.
Back to system restore images. Before proceeding it is good to note down w10 serial key. After the bloatware was removed and several hundreds of windows updates were installed (lucky me to have 300 Mbps network connection)... upgrade went well.
But then you think how to set up a clean OS. Microsoft provided a tool to prepare an USB boot drive or DVD. Nowadays USB is the option to use.

Skipping several hardware related issues (HP Elite has custom motherboard with custom power supply and no power for the graphic card - shame on you HP), I have started the USB: press escape during startup, choose boot menu, choose general UDISK 5.0.

Installation went well up to the last step where it showed me a dummy error:
"System Windows nie może zaktualizować konfiguracji rozruchu komputera. Nie można kontynuować instalacji."
Or
"Windows could not update the computer's boot configuration. Installation cannot proceed."

Any idea what to do next to have UEFI based fresh install of Windows 10 preferably with dual boot on HP Elite 8200 CMT?
I'll post updates as it goes by.

Samsung galaxy note 4 sm-n910c

No i stała się tragedia 1go świata: mój telefon padł. I to nie tak delikatnie tylko zgon nagły.
Samsung Galaxy note 2 GT-N7100 po przeszło 2 latach użytkowania zresetował się i utknął na etapie bootloadera (logo samsanga). Recovery pozwoliło mi na stwierdzenie, że NAND flash nie jest widoczny. Po resecie już się nie odpalał ani nawet nie ładował. Wszystkie dane, zaszyfrowane hasła itp. stały się niedostępne. A szkoda - n7100 świetnie mi się spisywał i nie licząc marki, knox-bitu i zamkniętych sterowników był super.

Nowy to Samsung Galaxy note 4 SM-N910C. Porównałem z Huawei Nexus 6p (nie mylić z p6... marketing jak widać w Huawei też działa na niekorzyść klientów). No i wyszło jednoznacznie, że przepłacanie połowy ceny note 4 za coś co nie ma slotu karty pamięci, rysika i nieznacznie się różni to pomyłka.

Teraz o tym nowym. Na minus jest czytnik linii papilarnych który jest 2D (trzeba przesunąć palcem po przycisku a prędkość zawsze jest zła).
Na minus kiepski (w porównaniu np. do s6) aparat.
Kamera pomiaru pulsu nie jest mi potrzebna skoro mam Xiaomi MiBand 1s.
Rysik można włożyć na opak z niefajnymi skutkami.
Grzeje się ciut (to exynos z cpu 8. rdzeniowym w governorze interactive).
Na minus brak roota.
Na minus to, że jest cienki i podatny na złamanie (note 2 był tu lepszy).
Na minus wystający aparat.
Na minus kształt i rozmiar przycisków sprzętowych.
Na minus wersja androida 5.x (podobno planują upgrade).
No i że tylko 3 palce można zapisać.
Na plus konfiguracja i cena, lampa przy kamerce, czytnik kart, gniazdo SIM micro a nie nano, fakt że jest jakiś czytnik linii papilarnych, rysik, 3GB RAM, fast charge i że wsparcie Qi (ładowanie bezprzewodowe co by się gniazdo nie psuło). W n7100 też było wsparcie Qi. Niestety w obydwu potrzeba dokupić odbiornik Qi (i nadajnik rzecz jasna).

Kupiłem szybkę hartowaną od 3mk (twardość 7H) i to też na minus, ponieważ jest za mała - zostaje pusta przestrzeń do brzegu frontu telefonu i szybka ledwie zakrywa wyświetlacz.

W najbliższym czasie będę zapewne chciał uzyskać dostęp do root'a i wyłączenia SELinux. A dalej zmienić governora co by wszystkie 8 rdzeni nie włączyło się przy oddalonym notatniku (nawet jeśli to vim).
