using TV LCD as monitor problem

I run UT3 on my laptop's monitor at a fairly high settings at 1920 x 1200. It will run perfectly. Recently we got a new tv that supports 1080p. I decided to hook my computer up through vga to vga, and the picture was so so. The resolution was much lower too, but i liked playing the game on the large tv. I invested in a DVI-d to hdmi cable and this allowed me to run a digital output to the tv at 1920 x 1200. The picture looks amazing, but it seems to stutter ever once in a while, and even once is too much when ur playing a fast pace game like UT3. Why does it stutter on the tv, but not on my laptop monitor? Also it seems that the tv cuts off the edged of the picture, and i cant see any of the edges. It seems like the tv is zoomed in a little, but it isnt. Is there a way to correct either of these situations? Thanks guys.

A 1080p TV's native resolution should be 1920x1080. Setting this resolution can sometimes "cut the edges off". Setting the resolution to 1768x992 should eliminate this problem.

The only way to reduce the 'jaggies' is to further lower the resolution/details to something your notebook video card can support.

I can play some games on my 1080p at higher resolutions than others. It all depends on the game...that is, how detailed the game's graphics are.

The "zooming" in effect is called overscan. The original purpose of it when TVs first came out was to cut off the edges so that the image seen would not have any scan line garbage on it. Many broadcast stations, and VCRs still require it, but many newer devices like game consoles, dvd players, digital cable boxes and PCs may not need it. Look for a function to turn off overscan or at least reduce it. On my LCD TV it's the screen format button and the option called "unscaled". This gives a perfect pixel per pixel screen match at 1920x1080.

I have had several plasma and LCD TVs the last few years and one thing I noted each time I shopped is that some TVs had options for disabling overscan and some did not. I made sure that I tried each TV out at the store with a laptop before I bought it. Some times the VGA connection worked better and sometimes the HDMI works better. My current TV does not even have a VGA connection but the HDMI works perfect, when my last TV had both but the VGA had no overscan and the HDMI did. Hope this helps!

Good info from the other members. My suggestion is to read your HDTV's manual. I game on my 32 inch HDTV from my lappy and my manual told me how to tune my auto settings of my TV! Whatever your manual specifies is what you should set display #2 for within your laptop. When you plug your TV in, your laptop will auto know how to send the signals!
