Because certain options in there aren't generally suitable for general use and can issues or annoyances, for example the input lag that Picture Clarity brings. So you basically go to your home screen, by pressing the House on your remote control. Press Left and you'll see Menu with 3 lines, press down and it'll select it and you'll see Settimgs, Connected Devices and Multiview. Click Connected Devices. Press right twice and you'll see the sources on the bottom, with SmartThings being thr first icon followed by TV etc.on the left down to Connected devices or Smartthings. Select your pc icon, click edit, and change the icon/type to something like BluRay player from the list dropdown. Now your TV will treat it as a media device and change the available settings presented that you can adjust. You should now be able to use Picture Clarity Settings. Don't turn Game Mode on during this, or it will revert to pc again / change the device icon in the menu I showed you earlier into a Games Console. What you CAN do is go to the settings, Connection > External Device Manager > Input Signal Plus and enable it for basically all the HDMI ports. If you don't usually use this with your PC or the S93 somehow didn't, once you change your "Bluray" back into PC, go to the all Settings menu, down to Connection and click it, click External Device Manager, Input Signal Plus and make sure it's on for your pc. You can also go back, and underneath you'll see Game Mode. Turn it on when you're usually using your PC or basically anything other than Blu Ray stuff. Turn it on and you'll also see Surround Sound turn on (blue checkbox). You can adjust a few more things in this menu to make the most of it as a monitor, experiment around and you'll find you'll end up with the perfect settings and no input lag.
Just wanted to throw this out there for you all, enjoy!
