[QUOTE="kszabo, post: 234442, member: 61646"] I don´t know... I use CoreAVC for h.264 playback. I can set "input level" to "TV (16-235)" and output level to "PC (0-255)". With this setting I get good picture. This sounds correct for me (it is the same correction that the display would do if I let it). We just need good codecs which can handle videos with TV-levels and expand it to 0-255., like CoreAVC 1.6.5. Correcting on display side is not a good idea IMO because: - other applications, GUI would be too dark (as you said) - few TVs support switching 0-255/16-235 (mine does NOT), so this is not even possible The 3rd solution like postprocessing with ffdshow ("levels" filter) I don´t use, because I could not use HW acceleretion with it (I like the avivo deinterlacing very much) Feedepee: I use ATi x1250 onboard I use Vista, and using EVR did not help at all in having correct level expansion (as some say) h.264 HD material works with CoreAVC, set as above (nice black and contrast) mpg2 (DVD, normal SDTV) works good with ATi decoder, HW accelerated, black corrected in Catalyst Control Center/Avivo settings (brightness set to appr. -18, contrast appr. +120). Other apps, desktop und MP Gui remains normal like that. [/QUOTE]
