Razlika izmedju TFT/TN TFT/LCD?

[njonjo]

Ljudi,zna li neko da mi objasni razliku izmedju ove dvije oznake,tj.tehnologije za monitore? Ovo pitam zato sto u SK pise da je Syncmaster 931bf unaprijedjena verzija modela 940bf iako se po oznakama ne bi reklo.A na samsung-ovom sajtu u specifikacijama ova 2 modela pise da je razlika u tome sto je 931bf TFT/TN a 940bf TFT/LCD.A pored toga je ovaj 931 jeftiniji za 50 eura, pa mi je to sve nekako cudno. Planiram da kupim jedan od ova dva modela pa bih zamolio da mi razjasnite ovu dilemu.

Hvala vam...

sve je to LCD, samo imas cetiri vrste panela:
PVA, MVA, TN i IPS, kao i njihova unaprijedjenja-sa prefiksom super ili premium.

posto me muka da kucam, evo copy/paste osobine ukratko, pa ako je sto nejasno-pitaj

generalno-najbolji je super IPS, ali zavisi i cime ces da se bavis-za recimo grafiku je CRT i dalje neprikosnoven, za igre se obicno koristi TN ili

TN film (Twisted Nematic)
- low manufacturing/retail costs
- restrictive viewing angles
- fast pixel response times
- dead pixels display white. Stuck pixels display RGB colors
- lower contrast levels means blacks are not as dark as VA based panels
- lower color reproduction

IPS (In Plane Switching)
- improved viewing angles over TN
- very good color reproduction
- slower pixel response times than TN
- dead pixels display black
- lower contrast levels means blacks are not as dark as VA based panels

Super-IPS (S-IPS)
- same as IPS except ...
- likely best color reproduction of all TFT
- less expensive to produce than IPS
- improved pixel response


VA (Vertical Alignment) Technologies

MVA (Multidomain Vertical Alignment)
- compromise between TN and IPS technologies
- superior color reproduction over TN but not as good as IPS
- very good viewing angles but less than IPS
- higher contrast than TN or S-IPS means very good blacks
- dead pixels are black
- slower pixel response than TN or IPS
- details can be lost when directly viewing dark areas

Premium-MVA (P-MVA)
- same as MVA except ...
- "overdrive" technology increases pixel response but still slower than TN
- may have slightly degraded color reproduction due to "overdrive" process

PVA (Patterned VA)
- same as MVA except ...
- larger viewing angles
- higher contrast levels means darkest blacks

Super-PVA (S-PVA)
- same as PVA except ...
- “Magic Speed” (the Samsung equivalent to Overdrive) improves pixel response
- slightly improved color reproduction
- slightly improved viewing angles

pa koji je onda od ta 4 ovaj 940 jer mu samo pise TFT/LCD kao Panel Type? mene igre ne zanimaju uopste. Najbitnije mi je koji bolje prija ocima jer se bavim programiranjem i puno gledam filmove.

oba su sa TN panelima sto ce reci da su oba "za igrace", ili u prevodu "manje boja zarad boljeg odziva"

u svakom slucaju-evo ti testovi sa benchmarka za ta dva monitora-pa procijeni sam.

940BF http://www.benchmark.co.yu/vidito.php?sid=11527
931BF http://www.benchmark.co.yu/vidito.php?sid=11130

za programiranje ne bi trebalo da osjetis razliku (osim ako ne programiras graficke aplikacije ili slicne kojima je prikaz boj broj jedan), za filmove-potreban je sto bolji prikaz boja i ugao gledanosti (sto ce reci da je TN panel dosta slab izbor, ali pva je preskup)....

ja nisam "sjeo" ni za jednim od njih, pa ti ne mogu reci koji je bolji, ali rekao bih da je nesto bolji 931bf (na osnovu citanja testova)

a veliko je pitanje i kakvo je tvoje oko (da li ces primjetiti razliku)

ja sam razmisljao da uzmem neki TFT jer mi treba monitor, ali kako sad stvari stoje-ako nemas za PVA panele-kvalitetni CRT je zakon-jes da je glmazan, da ima slabiju geometiju,.... ali je ipak po meni zakon
