Simple, like with a lot of video-related topics, make sure your display and sources match. Watch Blu-rays on a limited RGB TV and do your gaming and computing on a full RGB monitor. Just make sure everything is set to the same dynamic range, as any mismatch will promptly ruin your image quality.
Sure, it would be great if the industry could standardize even more and simply settle on one scale. Or if all displays could auto switch between limited and full RGB based on content. However, neither has transpired just yet so for now you should be aware of this.
Check your graphics card driver settings and display menus to pick the right scale, if such options are provided. Remember, for PC on a monitor choose full RGB whenever possible. For PC on a TV or Blu-rays on a monitor, limited RGB should be the better option.
