Manufacturers have launched new high-definition TVs and DVD players designed to match the speed of Blu-ray and HD-DVD discs. All the latest high-definition players we've tested now output at 24 frames per second – but it's still difficult to spot a properly compatible TV.
The official logo
HD-ready 1080p
EICTA, the same people behind HD-ready, have finally launched an official logo that guarantees high-definition DVD compatibility.
The new official logo HD-ready 1080p means the TV has a high screen resolution of 1080 horizontal lines (1920x1080), can process a 1080p HD signal and refresh the screen at 24 frames per second – meaning it will work properly with high-definition DVDs.
Similar sounding and looking logos such as, HD Full, 1080HD or 1080HD-ready are also commonplace. But crucially these labels do not guarantee high-definition DVD compatibility and exact meanings can differ between manufacturers. So be careful and look for the exact match.
24 frames per second should eliminate picture judder
24fps
In the absence of the official HD-ready 1080p logo, check for labels like this on HDTVs. It isn't an official EICTA standard but does mean the TV should process a 1080p signal and screen high-definition DVD without the juddering images.
Some TVs on the market claim to be neither HD-ready 1080p nor sport logos like 24fps but actually still work rather well with high-definition DVD, thanks to their superior digital processing software.
We're currently carrying out additional lab tests on older HD-ready TVs to see which are suitable for use with high-definition DVD players. Read our LCD and plasma reviews to find a Which? Best Buy that's right for you.
