I have been looking for a 42 inch 1080p hdtv and I have no idea what I am doing. I ONLY want to use my hdmi cable to plug it in to my laptop so I can use it as a jumbo screen. I do not need wifi or netflix or smart tv or any of that stuff on it. But what are all these contrast ratios? I see 50 thousand to 1, 150 thousand to 1, 500 thousand to 1, 1 million to 1, and even 5 million to 1, what do they do, are they important? And what does the hz mean? Some have 120hz others have 160, is that a big difference? Also is 3d important, I mostly play mmorpgs and they are not in 3d so will this feature be important to me? I would appreciate it if you could help me understand what the heck I am doing, and would love it if you could maybe address my questions in a video, thanks.

This is the tv I am looking at to buy: http://www.samsclub.com/sams/shop/product.jsp?productId=prod3220238&navAction=

i'll try my best to tell you what all the features you mentioned are as best as i can.

1) Contrast Ratio

the higher the number the better, the contrast ratio is a rating of Black against White. the darker the black the higher the number and darker blacks are good.

2) Hz

Hz are the measurement at which the screen refresh's its self.

60hz has been a standard for LCD panels for a while, it's good if your not going to be using it for 3D because it will cause a flickering and give you a headache. 60hz screens also have a slight blur, the blur is more visiable in fast paced images like sports games on the TV.

120Hz is a much sharper screen, it's best for 3d and fast paced images on the screen as the screen can refresh quicker and send out the image to each pixel faster resulting in a sharper image.

for you i'd not really think you would need 120Hz screen, or 3d.

one that you didnt mention is Response time. 5ms or less is best for screens, Response time is the time it takes a pixel to loose the colour it's been given and put a new one in.

Edit_

the screen that you have chosen isnt going to be the sharpest, due to the large 42'' and the 1920 x 1080 pixels, this is going to be a screen that you will have to put further away from you for it to be clearer and not cause you eye strain.

larger screens need more resolution to be better, otherwise your just getting the same screen real estate but stretched out.

Response time on this model is 2.4ms is that good combined with the low resolution?

What resolution should I go with on a 42 inch screen?

Make sure you get a TV that is 1080p. The other major standard is 720p, I would keep away from those. The larger resolution will make full HD (1080p) signals appear super clear. 720p signals will still work in the TV. As for Hz, that's how many times your TV will be able to draw a new picture each second. Most TV is at 30Hz, and computers are usually 60Hz. I really don't know any devices that are 120Hz compatible yet, I think it's more for marketing than anything else.

Do they make resolutions above 1080p? My current laptop has a 17inch hd 1080p screen so if I use the hdmi cable and set it to display using the tv only will the resolution go above 1080p? And lastly is 2.4ms a good response time?

Thanks for all the help you guys have offered so far!
