I've been stuck deciding between a few different TVs, namely the Samsung Q80/Q90 and Q9FN and the Sony X900F and X950G. I'm going to post my thought process and questions below Q80 vs Q90. Is there really that big of a difference? Q90 costs way more, but gets much better reviews. Are upscaling, black levels, or motion noticeably better on the Q90 than on the Q80? Q9FN also costs way less. Are the Q80 or Q90 that big of an upgrade over evne the Q9? Black levels: The Samsungs seem to have better local dimming which produces better black levels. However, the algorithms seem a bit aggressive and can cause loss of detail in dark areas. How does this look on the Q80/Q90 when the local dimming is set to low? Do you lose those great black levels or get really bad blooming? Color accuracy: Most places say that Sonys have much better color accuracy and from what I've seen in store that's true. Samsungs seem to oversaturate and make colors way too bright. Is there a way that Samsungs can get close to perfect color accuracy through calibration? I love the way colors look on the Sonys, but I would love to get the deeper blacks from the Samsungs if I could somehow avoid those neon super bright colors. Upscaling: Sonys supposedly have the best processors on the market. They are supposed to handle motion and upscaling from cable the best. How are motion handling and upscaling on the Samsungs? I watch a lot of sports and movies on cable, so I need a TV to handle these things and make them look smooth and natural. Ideally I want the TV with great black levels (without too much detail loss), accurate and vivid colors, smooth and natural looking motion, excellent upscaling from cable, good ability to watch 4K content streaming from Netflix. I am avoiding OLED due to burn in risk. I don't care about sound, viewing angle, or gaming features. From what I've seen: X900F/950: Accurate colors, More detailed picture, great processing on motion and upscaling, good, but not great black levels. More cost effective Samsung Q80/Q90: Bright colors, inaccurate colors (can this be calibrated close to Sony?), amazing black levels, loss of some detail in dark scenes (can this be fixed by putting local dimming on low?), good processing of motion (any way to make it stutter and flicker free?), good upscaling. More expensive for Q90, so is Q80 still better than both the Sonys? Samsung Q9FN: Appears to get great reviews in terms of black levels, but looks like it might have problems handling motion. The way I see it, the Sonys are great out of the box, but if it seems like the Samsungs can be calibrated in terms of things like color accuracy and motion handling to be close to the Sonys then I would rather go Samsung. Sonys have their strengths but can't be calibrated into better black levels, so I'm just seeing if maybe I can get the best of both worlds with one of the higher end Samsungs. I plan on using the TV the following way: Sports, movies and news from Comcast cable box (80%) Netflix shows and movies (15%) Blue Ray (5%) Hope to hear from some of the experts here!
