T.V's have their own build in graphics card to power their screens. A monitor doesn't and that is why they are used on PC's. Lets me say this - I am using a Macbook Pro right now on a Samsung 27" Monitor, It lags so much on games and takes so long to boot up, When i plug in my 42" T.V. as my display it runs much faster and boots up way quicker. The Integrated graphics on my MBP can't power the monitor for gaming as it is really only intended to power it's own display. You can plug in 3 T.V's to you laptop and it will still run faster than connecting up one monitor. With a console, most people use it with their T.V and usually never with a monitor.
My monitor supports HDMI and works perfectly with a console and laptop. When you plug in a pc or another machine to a TV, your graphics card (in the pc/console) is still the thing doing the rendering and outputting the image onto the TV. At the same time gaming on a mac wouldn't be recommended (sleek design leads to heat). That's why I have no idea what you were talking about lol. Either way, we're going off topic now :S

I aren't saying that it doesn't work well on console, A console has a build in graphics card for just sending the T.V. what goes on the display and/or used to actually power a monitor. A console can power a monitor pretty well, But if you were to play really graphic intense games on it it would lag a lot, if you had a T.V connected it wouldn't be so bad. What graphics card is in your laptop? my MBP has integrated graphics and i tell you it is terrible playing games at 1080p on my monitor. I played crysis 2 on low and it still lagged, High- like 2 fps and below.
Last answer before a mod kicks me for going off topic:
That would also depend on the refresh rate of the monitor if things look choppy. Games run terrible on integrated graphics anyway lol, let alone playing crysis 2 at 1080p. My laptop uses a GT 635m for intensive applications and the HD 4000 for web browsing etc. Lag comes from the hardware running it being insufficient, unless the screen displaying it has a crappy refresh rate or response time.
GTA 5 isnt out on the PC yet lol. Technically it should run smoothly at medium high settings, depends on how Rockstar optimizes the PC port.
I know that. I am waiting For it to come out though. You know I just hope one day People on a PC can play people on xbox and Play Station. All my Friends use Consoles and Not PC, i just want to play them but I can't. I don't have a console either.
