I am playing FFXIV on a 52" LCD mounted on my wall...hooked up to surround sound ;)
I absolutely love this setup for my gaming/media PC and it is perfect for FFXIV.
For those of you that are experiencing trouble like input lag, you have the desktop set to the wrong resolution for your TV. Even if your TV has a 720p native resolution (for example), you would have to set your PC's resolution to 1368x768.
For those of you with lines or if the screen is cutoff, you will have to mess with the scaling options of your desktop either by using the Nvidia control panel or ATI's CCC.
HDMI and DVI are going to be the exact same digital signal (except HDMI will carry audio). NEVER use VGA or any analog output to an LCD TV unless that is all that is available.
If your desktop icons and text are too small, change the DPI settings for your desktop to something like 125-140% bigger. If FFXIV text seems too small, then don't run it at 1080p...use 720p fullscreen instead and everything will be much bigger while viewing from your couch.
Let me know if you need any help or have any questions about PC on a TV...I've configured a good amount of these types of setups before. Once everything is optimized, you will never want to sit at a desk for PC games ever again!...especially if you can use a controller....but, that's a whole other thread!
