Am going to start looking at 4K TVs and would appreciate recommendations of 4K demos to use because I realize some stores set their TVs for Max appeal.
Hope someone as devised some tests to check for this.
Do try to read the reviews but many TVs never get reviewed so helps if can bring some tests.
Googled using keywords 4K demo videos got ~ 23,900,000 results (0.35 seconds) with "..." got 2,400 results (0.30 seconds) and started checking.
To date the only tests I have found are "Real UHD HDR 10 Combination Test Pattern, luminance levels and primary colors (chromecast ultra)"
and "dynamic horizontal multiburst 4k (2160p Ultra HD) | resolution test with phase modulated sine waves"

Hope there are more tests to check 4K TV settings!
