ATI Radeon Overlay Bug

Recommended Posts

Hello!

 

Although it is not that widely known, ATI Radeon cards do have a severe problem with overlay in high resolutions. That means you have only half the horizontal resolution at high resolutions and refresh rates. For example at 1600 * 1200/32/85 the overlay resolution is only 800 pixels. You can easily notice it when looking at borders or letters, especially when watching TV in a relatively small desktop window.

 

Follgott, moderator of the HDTV-forum at www.beisammen.de, has thoroughly investigated the matter. Here is the link to the corresponding thread (German only). I've linked directly to the end of the thread because Follgott has posted some pictures there for better illustration, but I recommend to read from the beginning.
