Thanks for the input! It’s good to check TV’s in a store, I totally agree. There are some problems with it, though: the light conditions are different (much brighter in a store), the TV settings (not every store is keen to let customers play with the settings) and the footage that is shown.
Some time ago, I compared the A8F, the A9F, the LG C9 and the Philips OLED803 in a large store. After some persuasion, the store personnel let me observe a hockey match in SDR on the A8F. A very long cable was needed for this. I wasn’t particularly impressed with the motion, but blamed it on the standard TV settings. This motion was a bit better than on the YouTube video of the A9G, though. In this video, from 8.28, it seems that the motion on an earlier Philips OLED model is better than on the Sony A8F: youtube.com/watch?v=6Q2AMsrirnw.
Philips might have the upper hand on motion then, but the general image quality of the A9F blew me away, wow! More appealing to me than the OLED803 and C9. The HDR footage was impressive with good motion. Reading reviews, it seems the image quality of the A9G should be pretty much the same, but I’d prefer the upright position of the A9G panel. Sadly, the HDR footage in the store doesn’t say anything about 1080i broadcasts or 24p movies, in particular the motion, so I still place some value on video reviews on YouTube. It’s reassuring to read that the motion on the A9G is called ‘best in class’ in the US.
