Monitoare LCD - putin ajutor

STR8_ · Post by **STR8_** » Tue Jan 03, 2006 9:54 pm

L1780U VS L1780Q

UPDATE : Basul de la 4 coloane audio 100w RMS folosite la volum mare, poate crea dead pixels ? - Asezate la 1M distanta de monitor !

Cateva intrebari legate de cele 2 .

1) arata identic ? in poze nu prea imi dau seama

2) care are o calitate a imagini mai buna. Stiu ca q-ul are 8secunde. ma intereseaza o calitate a TEXTULUI cat mai buna, culorii bune, si desigur design-ul.. nu vreau samsung, sau altceva , sunt prea comune

3)daca iau un monitor de 19 ... stiu ca are aceiasi rezolutie -> pixeli mai mari -> calitate text mai proasta, sau ma insel ?

4) este diferenta mare in jocuri intre 8 si 12 ns ? Ce conteaza la un monitor LCD pt a se vedea bine in FILME ?

Hehe!LG 1780Q il am eu de cateva zile si pot spune ca este exceptional!Se vede textul foarte bine si totul este foarte clar!Jocurile se vad excelent!Merita!

PS:Eu l-am luat de pe un alt forum cu 11 mil (nou nout sigilat si sunt foarte multumit de cum merge pana acum)!

NOVI.. avem gusturi asemanatoare la componente lol .

Doar 10 mil cu tot cu TVA .. nu este cam ieftin ?

Ba da!Dar acel monitor are 12 milisecunde si se vede ceva mai incetosat in jocuri!

OK NOVI> M-ai convins, daca il gasesc in iasi pana in 12-13 mil il iau.

Alte pareri despre LG 1780U ?

Monitoarele LCD suporta 16 Milioane culori = 24 BIT NU ? ( 2^24 = 16,777,216) NU ?

IMPORTANT
Monitoarele LCD suporta 16 Milioane culori = 24 BIT ? ( 2^24 = 16,777,216) NU ?
Cum setez eu 24 bit ? Am doar 16 si 32, iar pe 16 se vede foarte prost .
Deci merge : 1280 * 75HZ *32BIT sau 24BIT ? SAU CUM ?

Am vazut la cineva un monitor(LG 1715s) care nu merge decat 16 bit in 1280, doar in 1204 merge 32 bit -Are o placa video f proasta integrata, care foloseste din ramul sistemul. Poate fi asta cauza ?

Cine ma lamureste Clar ?

Da. Modul 32-bit este la fel ce cel 24-bit din acest punct de vedere (numarul de culori).

http://www.scantips.com/basics11.html wrote: Video boards for the last few years are 24 bit color (called True Color). Note that there is no 32 bit color. The confusion is that 24 bit color mode normally uses 32 bit video mode today, referring to the efficient 32 bit accelerator chips (word size). The 24 bit color mode and so-called 32 bit video mode show the same 24 bit colors, the same 3 bytes RGB per pixel. 32 bit mode simply discards one of the four bytes (wasting 25% of video memory), because having 3 bytes per pixel severely limits video acceleration functions. Processor chips can only copy data in byte multiples (8, 16, 32, or 64 bits). A 24 bit copy done with a hardware video accelerator would require three 8-bit transfers per pixel instead of one 32-bit transfer. 32 bit video mode is for speed, and it shows 24 bit color.

24 bit color is 8 bits each of RGB, allowing 256 shades of each primary color, and 256x256x256 = 16.7 million color combinations. Studies show that the human eye can detect about 100 intensity steps (at any one current brightness adaptation of the iris), so 256 tones of each primary is more than enough. We won't see any difference between RGB (90,200,90) and (90,201,90) but we can detect 1% steps (90,202,90) (on a CRT tube, but 18 bit LCD panels show 1.5% steps). So our video systems and printers simply don't need more than 24 bits.

If our screen is set to show say 1024x768 pixels, the video board has memory chips to hold that current 1024x768 pixel screen image. This memory image is the entire basis of our video system, it is what we see. The video board requires 3 bytes of video memory per pixel for 24 bit color, or 4 bytes for 32 bit video. So a 1024x768 pixel screen size (2.3 MB) requires a 4 MB video board. A 1280x1024 pixel screen size requires 4 MB if 24 bits, or 8 MB if 32 bit mode. Additional video board memory does not affect 2D video speed, it only allows larger combinations of screen size vs. color depth.

Memory is cheap today, and current video boards have 8 or 16 MB of video memory (some have 128 MB for 3D games). We all probably have sufficient video memory for most 2D screen sizes. But this is recent, it certainly wasn't always that way, older computers (when memory was expensive) had real shortcomings in that department not so long ago.

Da. Memoria video minim necesara pentru 1280x1024x32 (8MB) este mai mica decat cea pentru 1024x768x32 sau 1280x1024x16 (4MB). PS: Valorile din paranteze sunt rounjite pana la valorile cele mai intalnite pe placi video.

Acuma nu stiu ce ai tu impotriva monitoarelor SAMSUNG. eu am un Syncmaster 172x (8ms) si e bestial. in jocuri nu "laguie" culorile sunt vii si textul e ireprosabil. Or fi ele cum spui tu "comune" dar din punctul meu de vedere au un design super fain si performante pe masura.

Si o ultima intrebare ! ca sa revin la ideea topicului !

Se observa diferenta reala intre 12 NS si 8NS ? merita diferenta de 3 mil ? Eu ma joc ocazional, ma intereseaza in windows, am inteles ca o latenta mare poate provoca un efect de ghost-ing cand se face scrool pe o pagina..

daca iau un monitor de 19 ... stiu ca are aceiasi rezolutie -> pixeli mai mari -> calitate text mai proasta, sau ma insel ?

In jocuri cum e? 12NS VS 8N ? - diferenta mare?

Diferenta este mica chiar imperceptibila de catre unii, nu merită 3 mil. pentru 8ms.

E totusi mai safe sa asezi crocodilii aia la o distanta mai mare de 1 m de LCD. Vibratiile produse nu cred ca sunt chiar indicate. Eventual sa te asiguri ca boxele nu au contact cu biroul !
