concernant de potentiels points faibles, sur avbuzz on peut lire :
- "some areas of the vertical alignment are fairly straight but some areas are not. i think it's not related to alignbment but color aberration from optical lens. The red panel slightly offsets to the right hand side in a degree of 3\4 pixel. In general, the optical quality of lens at entry level grade projector is not quite good because of the limited budget."
- " unfortunatly there is a 1.5 inch vertical bar from top to bottom on the left handside displaying a bit different luminance from adjacent pixels. The same verticale bar appears in the full range of the gray scale but less visible at whiter levels."
- "The picture is smoother than hs60 but not as sharp as hs60"
- "the noise level at the natural mode is slightly more than that of hs60 at high lamp mode"
(une comparaison des modes "low" aurait été interessant)
- "there is certain amount of light leaking from the air exhaust on the front panel"
- "
there are macro tearing at 48 hz, 72 hz"
- "when the image jump from avia menu to the black, the luminance is dropped gradually, say in 10 seconds to the minimum level" (il ajoute que c'est comme sur le hs50, pas le hs60)
- "hs60 demonstrate higher deinterlacing power"
- " although the lower black of 0,02 lux is lower than 0,03 lux of hs60, it's eye seeing black level is much higher than hs60. I guess it is because before TW600 never drops to the darkest black when the movies keeps changing scenes.
- " the black level is inconsistent , some movies like "tigres et dragons", "moulin rouge" are fairly good..but some scenes at star wars 2 are not so good"
- " tw600 displays better contrast of dark object to bright object in the same picture. but no improvement on mid gray to bright. The overall contrast performance is lagging well behind hs60"
- "it present reasonnable shadow detail, but not quite outstanding, the black will be to gray if i raise the low level to make them look clearer"
- "it seems that tw600 doesn't hide the noise as good as other projectors. on the oppposite , you can say tw600 reflects more realistic condition, however, we still prefer clean pictures."
- " its iris auto does improe black level and contrast but the progress is not remarquable. it is unfair to compare tw600 with hs60 since there is hk$7k price difference"
ps : ces "points faibles" demandés par treza sont bien sur la pour etre "discutés" et a mettre en parralel avec ceux trouvés dans d'autres tests (notamment ceux dans la presse ou il est moins bien classé que d'autres d5)...meme s'il a l'air de bien connaitre son affaire et adapter un protocole serieux, CKL n'est surement pas infaillible.
pps : sans meme parler du reste (ce qui ressort regulierement du test sur avbuzz est que le projecteur brille plus sur des mires qu'avec des images animées : niveau de noir, contraste,..sans doute a cause de l'iris dont le systeme s'apparente a celui du ptae700 selon lui) le tearing en 48/72 hertz est vraiment un probleme pour les utilisateurs de pchc, probleme que connaissait deja apparemment le tw200...(a confirmer au plus vite.)
le reste du test (et donc des qualités de l'appareil)
