I seen how Panasonic ilustrate the superior chroma handeling with a OPPO 203 vs Panasonic UB900 player with a faint zone plate, showing how they have more chroma information all the way out in the corners, found that a problematic test, as the zone plate dont trigger the ringing with its soft edges, and if reducing the chroma sharpness to -3 on the Panasonic, the OPPO would actually maintain more high frequence chroma information. The Xbox One S have in my opinion better chroma handling than the Panasonic, as it do somewhat the same as Panasonics chroma multitap processing, just without the heavy distortion addet.Īlso find the Xbox scaling much smoother. I seen the new JVC NX9 projectors also add some ringing, so they are not good reference displays for this test, think the LG oled do well, so do older JVC projectors.
The ringing reduces with a -3 chroma sharpness, but also reduces chroma high frequence responce, its not possible to completly remove the ringing even with a -6 chroma sharpness, and there ill say there is no high frequence luma response, they go all black, normaly the ringing shows up first on the chroma multiburst pattern between the red and blue bar on the left side, where you see the ringing on the edges, and they eat the black line/ distance in between the vertical bars.
Does spears and munsil work with meter 1080p#
The screen i shot that pic is a LG oled, i first noticed the panasonic ringing on a old Pioneer 1080P plasma with the UB900. That is a limitation of the display.Ĭlick to expand.Dont remember the name of that pattern, it was the only 4K pattern i could find back then, ill try ilustrate it using the chroma multiburst pattern on the S&M UHD disc. No, adjusting those won't make blacks more black. Would need to evaluate it and find out what works best. The correct setting can change from one vendor to another as well as one generation to another. You display a 100% window pattern and adjust the backlight until the meter reads 100 cd/m² (30 foot lamberts) if your goal is to see it at the level it was mastered for. I recall Samsung clipping headroom by default in SDR, so contrast had to come down.īacklight requires the use of a light meter to set correctly. (some lighter and some darker) Correct means all four were the same. Wrong means the four bars were different levels. They noticed RGB was wrong and YCbCr was correct. Looked at the four bars that appear green. Selected the HDR Color Bars test pattern on the disc.ģ. When they set it to YCbCr, color decoding was correct. On another forum, a user noticed that sending RGB from their player into their Samsung resulted in the wrong color decoding. You turn it on to set color and tint as well as to verify color decoding and then turn it back off. The RGB only mode is not a setting you adjust.
