FAQ
TL;DR: Sony’s XG9505 peaks at 1,180 nits HDR brightness—28 % higher than Samsung’s Q70R—while “colors are practically identical after calibration” [Rtings, 2019; Elektroda, Ludwik XVI, #18236379]. Both use 120 Hz VA FALD panels; choose Sony for HDR pop, Samsung for faster Tizen menus. Why it matters: Picking the right 65-inch set avoids regret on a €1,200+ purchase.
Quick Facts
• HDR peak brightness: Sony XG9505 ≈1,180 nits; Samsung Q70R ≈920 nits [Rtings, 2019].

Which model delivers the brightest HDR highlights?
Sony’s KD-65XG9505 tops about 1,180 nits, whereas Samsung’s QE65Q70R hits roughly 920 nits. The extra luminance helps render specular highlights and shadow detail in HDR movies [Rtings, 2019].
Does Android TV on Sony XF/XG series really lag or crash?
Owners report slowdowns and occasional reboots when RAM nears its 2 GB limit, especially after several apps are installed [Elektroda, Ludwik XVI, #18239423]. One user saw a full screen of black-and-white squares after an app exit, followed by an Android restart [Elektroda, mordip, post #18247627]
How does Samsung’s Tizen OS compare in speed and stability?
Tizen loads menus and apps 20-25 % faster, according to side-by-side user tests [Elektroda, PAM2019, post #18240057] Fewer background services mean fewer freezes, but app selection is smaller than Android’s 7,000+ titles [Samsung Dev, 2023].
Are color differences visible once both TVs are calibrated?
After basic calibration, colors measure within ΔE < 2 on both models—indistinguishable for most viewers. “Colors are practically identical after calibration” [Elektroda, Ludwik XVI, #18236379]. Pre-calibration, Sony ships warmer; Samsung leans neutral-cool.
Which TV handles low-quality cable or satellite signals better?
Sony’s X1 Extreme/X1 Ultimate processors upscale SD and 1080i feeds with fewer artifacts, a benefit noted by multiple shoppers [Elektroda, Grayswandir, post #18236208] Samsung’s upscaling is good but can look slightly soft or ‘foggy’ in Standard mode [Elektroda, mordip, post #18249519]
Is input lag low enough for gaming?
Yes. In Game Mode, Q70R averages 14 ms and XF9005 about 24 ms at 4K/60. Competitive gamers may feel Sony’s extra 10 ms, but casual players rarely notice [Rtings, 2019].
Does the CAM module freeze Sony TVs?
Some users report Guide/Back button loops causing CAM de-authentication on XF9005, leading to temporary black screens [Elektroda, Ryszard49, post #18244827] Using an external set-top box eliminates the issue.
For dark-room movie nights, which set shows better blacks?
Samsung’s deeper native black (≈0.02 nits) and aggressive local dimming create higher perceived contrast, especially in letterbox bars [Rtings, 2019]. Sony blooms more around subtitles, a “white glow on black” effect [Elektroda, PawelTV, post #18247634]
Is upgrading from Q70R to Q80R a big step?
Q80R adds an ultra-viewing-angle layer and ~20 % more dimming zones, but peak brightness and processing remain similar. Unless you watch off-axis, savings on a Q70R may outweigh the modest gains [Rtings, 2019].
Are Sony XF90 and X900F identical?
Yes. XF90 (EU) and X900F (US) share the same panel, chipset, and firmware; only regional tuners differ [Elektroda, Ludwik XVI, #18778164].
How to avoid judging TVs by incorrect store settings?
- Ask for ‘Cinema’ or ‘Movie’ mode on each set.
- Disable motion smoothing.
- Reduce store lighting or shield reflections.
This neutralizes showroom presets that exaggerate color and brightness [Elektroda, ikarus78, post #18218289]
What can I do if Android slows down after a few years?
Clear app cache monthly, uninstall unused apps, and disable Google Assistant’s always-listening. If still slow, an external streamer like Nvidia Shield (3 GB RAM) restores snappy navigation [Elektroda, Ludwik XVI, #18246695].
