Many years ago I used a similar plate and I can't say I remember much about installation... I assume that means I didn't hate it... I usually remember those.
For today, I just googled for "decora keystone" to find the above link/picture to share with you. In general, my experience is that not all keystone jacks/plates are created equal. It's usually best to stick to the same brand/manufacturer for an installation. Sometimes you can get others to fit, but it's not always as clean. Also in most of the situations where I've used these it's been for network/phone jacks and I've been more concerned with having good quality punch down terminals in the back and that drove my buying choices. If it were all network jacks and had as many ports as what you specify above I would have used use a patch panel.
If I am doing A/V, which I assume it what you are doing, I usually use one of the below pass through wall plates from Monoprice. They are smaller overall, easy to work with and you can get a surprising amount of cabling in there for just a two gang wall plate. Personally, I try to limit the number of break/connection points in my a/v cables and whereas jacks/wallplates like above look nice when they are empty/new it does add two more points of connection (front and back of the jack) where things can go wrong. When they are fully connected they are usually behind a bunch of gear or furniture and I don't care so much about the looks anyway. The below plates let me just pull my speaker wire through and then I terminate the bare wire to the amp/speaker. HDMI cables just pull through and I don't have to worry about strain on the back side of the wall jack, etc. Your requirements and preferences may be different of course.
