The issue has always been the updates surprise us when we power on our systems; it can be hours until Sony releases a changelog on their official site—you get tired of reading forum after forum trying to figure out what the new update actually did. We were happy to hear about Sony's new official PlayStation blog, and we hoped that they would be more proactive about getting this information out in a timely fashion. It looks like they're listening, as a post to the blog yesterday told us to expect firmware update 1.81 this morning, and told us exactly what it would do.
"Most notably is the RGB Full setting which a few of you wrote in about. In 1.80 we added an option to the XMB under settings allowing you to choose between RGB Full and Limited. Basically if you are connecting your PS3 to your TV using an HDMI cable, and if your TV supports RGB full range, the picture quality may be improved when this option is set to Full. Some of you pointed out that the Full setting would sometimes revert back to Limited and 1.81 will address this issue. Please keep in mind that this setting is only effective when the PS3 is connected to a TV using an HDMI cable. You can download the update tomorrow from PlayStation.com or through your System Update option on the PS3 XMB."
