If you had a choice between these two tv's, which would you buy?

A. 800:1 contrast ratio and 400 cd/m2 brightness

B. 700:1 contrast ratio and 500 cd/m2 brightness

They are exactly the same except for these factors. Would you buy A or B?

Brightness isn't that important in LCD's as most of them are quite bright. Contrast ratio determines the black levels, which is more important in LCD's. Both of these contrast ratios are waaaaaaaaay too low. A if I have to choose between these two.

Those should be LCD monitors, which explains the low contrast. Again, contrast ratio is more important that brightness. Generally, anything above 300cd is more than good enough.

So what do LCD monitors look bad because of this?

No, it's just that LCD technology isn't as good as plasma for producing good contrast ratio's(i.e. pure blacks and whites) However they are getting there. A good Samsung TV normaly has between 2000;1 and 5000;1 contast Ratio which is more than enough for realistic colour, and as far as brightness is concerned 300Cd is more than sufficient.

Kind of, but not quite. LCD monitors tend to have lower contrast ratios than LCD HDTV's, mostly due to the fact that things like web surfing and productivity do not require high contrast ratios.

Yes, but even then monitors are catching up fast, you only need to look at the newest screens available, some(I think there is an LG 20In model) that has 2000;1 Contrast ratio, and anyway He's talking about buying a TV not a monitor, if it's for PC Gaming or other windows work, then a good 20-24In monitor would be better than a TV mainly due to thier higher resolution, there's another point to consider,resolution.

I was commenting SSJBen's comment attributing low contrast ratios with LCD monitors, not really commenting on the OP.

Sure, monitors are starting to get better contrast ratios, but the ratios for LCD HDTV's are getting higher too. Samsung has those 25000:1 LCD's. It's probably dynamic contrast, but static is still higher than 2000:1. Monitors will still usually have lower contrast ratios. :D

TV specs rarely tell the truth. I wouldn't care which one I pick.

And let's face it Monitors are used by graphica designers and animation professionals, so if they're good enough for such colour sensitive work as that ,then they'll almost certainly be good enough for the general consumer. Personally I can't distinguish much from a good HD-LCD TV and a good LCD Monitor in terms of colour/ brightness and overall picture quality, and remember what I said earlier on resolution, a monitor is likly to offer sharper visuals and more desktop space to work with due to the higher res.
