Chirurgia cranio-cerebrală minim invazivă
Tehnicile minim invazive impun utilizarea unei tehnologii ultramoderne. Endoscoapele operatorii de diverse tipuri, microscopul operator dedicat, neuronavigația, neuroelectrofiziologia, tehnicile avansate de anestezie, chirurgia cu pacientul treaz reprezintă armamentarium fără de care neurochirurgia prin "gaura cheii" nu ar fi posibilă. Folosind tehnicile de mai sus, tratăm un spectru larg de patologii cranio-cerebrale. www.neurohope.ro |

Mergi in magazin, vezi un LCD fain, iti plac pretul, designul, luminozitatea, contrastul si culorile, insa dupa ce intrebi vanzatorul ce tip de panel are in el, iti vine sa iti ceri scuze ca l-ai injurat.
Va rog sa postati aici modelele de monitoare pe care le folositi sau despre care stiti ca au paneluri MVA PVA etc., adica cele cu culori reale 16.7, si cu unghiuri maxime de vizibilitate, mai ales pe verticala. Pe mine unul ma intereseaza un 20" wide cu TR de maxim 12ms, avand in vedere ca preturile au tot scazut. Nici google nu e prea de ajutor in privinta asta, asa ca nu postati cu "google it". Mersi. |

Pe site-ul asta poti cauta si dupa tipul panoului (de exemlu, folosesti "PVA" ca termen de cautare in baza de date). |

--------------------------------------------------------------------------------
LCD Panel Technology Type and Characteristics 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 Purchasing Considerations TN Gamers Considered a "gamers" panel due to it's fast pixel response times which reduces trailing images know as "ghosting". However, this advantage has been reduced by new technologies to accelerate pixel response times in other panel types. Colors and contrast tend to be weak and blacks are not truly dark. Viewing angles are significantly limited. However, monitors based on this technology tend to be inexpensive. IPS / S-IPS Graphics Work or Web Browsing Considered to have the best color reproduction of all panel types, these panels are well suited for graphics work or web browsing. Pixel response time is also good but slower than the TN "gamers" panel. Contast and blacks are also less dark than VA panels but viewing angles are excellent. MVA / P-MVA / PVA / S-PVA Compromise for All-Around Use These panels are a compromise between the fast pixel response times of the TN panel and the excellent color reproduction of the IPS panels. Contrast and blacks are best of all the panel types. Viewing angles are similar but slightly inferior to IPS.

la acelasi pret poti sa iti cumperi un DELL 2007WFP singura pb fiind tipul de panel pe care ai noroc sa il primesti S-IPS sau S-PVA al 2lea fiind un pic mai slab decat primul. |

Salutare !
Si eu sunt pe cale sa fac trecerea de la CRT la LCD, si acum oscilez intre un Samsung 971P, sau un Dell 2007PF, ambele in jurul sumei de ~ 1350 RON. Dell am inteles ca poate veni in doua variante, fie cu pannel S-IPS (AO), de 16ms real, fie cu un pannel S-PVA (Samsung) dat la 8ms G2G, care banuiesc ca sunt tot pe la 16ms real. Samsung-ul cred ca are acelasi tip de pannel, doar ca de 19" in loc de 20". Ma intereseaza mai mult vizionarea de filme, fotografii, web-browsing, text-editing. Nu va fi folosit la jocuri. Vreo sugestie ? Un pannel S-IPS sa inteleg ca nu va reda prea bine nuantele inchise (negru) ? Are cineva idee daca intre monitoarele astea doua ar putea exista o diferenta sesizabila atunci cand se vizioneaza un film ? Multumesc mult ! |

la filme conteaza foarte mult negrul sa fie negru - ips sint slabute - exista multe TN mai bune ca ips la negru .
amindoua monitoarele sint prea scumpe - 971p am vindut eu anul trecut cu 8 mil nou . iar dell-ul de 20 este prea mic .- nu are negru asa bun - si este si scump . daca dai de un dell cu panel prost - o sa fie mai rau decit un tn la privirea din unghi - mai putin cel de sub monitor . are tendinta sa deformeze culoriile si spalaceste imaginea . daca nu ai nevoie neaparat de un pva mva - eu ti-as recomanda mai degraba un 26 inch TN de la iiyama - costa undeva pe la 14 mil - si este un monitor bun - are negru bun - unghuri acceptabile - viteza buna si are si gamut ok . singurul dezavantaj ar fi daca vrei sa il folosesti in spatii foarte luminate - pentru ca nu are luminozitate foarte mare . |
