Regarding contrast ratio, 71F's dynamic CR's are better in my measurement.
But A650 is better in panel's static CR with turning off any dynamic backlight control.
71F(Korean Model# F81BD)'s Max CR measured 27525:1(even better than Samsung's own 25000:1 spec) and then blacks read 0.012 nits that time.
That's close to Pioneer Kuro's blacks(0.013 cd/m² initially, 0.006 cd/m² after few seconds)
On the other hands, A650's max dynamic CR is limited to around 10K to 1, still better static CR than 71F.
Most new TV's from any major brand, IMO, have enough blacks and CR's unless you're watching it in a darkened room
A650 has around 2000 to 1 non-dynamic, static CR.(2291 : 1 for my measurement)
And that's pretty good enough and better than 71F, I think.
I assume Samsung changed their dynamic backlight control algorithm less aggressively this time and that's why 71F has more CR.
But A650's panels static CR's higher than 71F.
I'm not satisfied with A650's black uniformity, though.
Usually Samsung and Sony's PVA panels are better in black levels and uniformities comparing to LG's IPS panels.
A650 is still slightly better than LG's, but not as good as previous Samsung models.Quote:

If you want to choose Warm1&2, picture mode should be 'Movie', not 'Standard' or 'Vivid'.
