Best 40"-50" HDTV for connecting up to a Gaming PC?

if you do not want lag then i'd suggest one of two things:
-not geting a 120/240hz tv (100/200hz in your local i believe) since they only accept a 60hz input (50hz in your local most likely) and fake in the rest of the frames which results in a slight lag.
-if you do get a 120/240hz (100/200) tv make sure it has a working game mode which eliminates the extra frame processing and runs the tv at 60hz (50).

why? quite simple: the tv only accepts a 60hz (50) signal. some tn monitors however can accept a native 120hz (100) signal so are capable of actually displaying more frames direct from the pc without lag-inducing post processing.

if you are very sensitive to response time or motion blur i would highly suggest testing out the televisions before you purchase them. another person i'm helping right now i believe has such a sensitivity (eg he can see "motion blur" on televisions). i personally use a television and while slight i dont have any real problems with it. i'm not sure if the 120/240hz (100/200) are better. i would think they are since they are capable of displaying more frames (after post processing) which should mean they have a faster response time. you would just need to watch out to make sure the 60hz (50) mode works.

you may also want to realize that the sharpness of a 40-50" television is going to be not even close to what a monitor is. for example..

copied from manofchalk and my sticky at the top of peripherals:

common monitor sizes at 1080P

1920x1080 @ 20" = 110 ppi
1920x1080 @ 22" = 100 ppi
1920x1080 @ 24" = 92 ppi
1920x1080 @ 26" = 85 ppi

common television sizes at 1080p

1920x1080 @ 40" = 55 ppi
1920x1080 @ 42" = 52 ppi
1920x1080 @ 46" = 47 ppi
1920x1080 @ 50" = 44 ppi
1920x1080 @ 60" = 37 ppi

for reference here are some other product ppi numbers

1136x640 @ 4" = 326 ppi, iphone 5 retina display
10000x10000 @ 20" = 707 ppi, prototype lcd display advertised in cpu mag
2560x1600 @ 30" = 100 ppi, dell 30" ultrasharp monitor
1920x1080 @ 5" = 440 ppi, typical 5" 1080p android phone
1280x720 @ 4" = 367 ppi, typical 4" 720p android phone
640x480 @ 32" = 25 ppi, typical 32" 480i crt tube television

i personally use a 40" television and while true that it is not as sharp it works out better since i use it with a pc, ps2 & ps3 which are used more for playing media than work functions. you might need to bump up windows fonts to the next level (5-10%) and view webpages at a slightly higher zoom (100 or 105%) but other than that it works out great.

brands i would recommend are sony, samsung and lg in that order (as for overseas brands i cannot really say).

most televisions can be wall mounted. i would suggest getting something heavy duty though instead of something cheap.

Panasonic Plasma's for me on tv sets have the least amount of lag and good black levels.

But like the guy above stated Monitors for gaming are seriously the way to go if you are going to be hooking up a pc.
With the graphics card you are looking at you will easily be able to push well over 100fps in alot of newer games so might as well
get something that is capable of displaying all those frames. For what ever reason HDMI inputs on tvs are limited to 60hz which effectively means when hooking a pc to them maximum frame rate you will be able to input is 60fps.

I have several of the Asus 144hz monitors. Two 144hz 24" monitors and one of the newer 27" 144hz monitors.

I also have one of the Yamakasi Catleap 2B IPS panels overclocked to 120hz running at 1440p That looks nice but graphics card struggles
to maintain that refresh rate at that res.

I also have the BenQ XL Series XL2420TE Both the Ben Q and the Asus are amazing when you use LightBoost with them 120hz no flickr real sick.

I generally game on my Monitors even with my consoles but when i have friends over I use my two year old Panasonic VT series Plasma. At the time when I bought it nothing on the market for fast motion was better period.

@op

i would highly suggest going to a few local stores and looking at televisions in person as honestly there is no good way to tell if the television is for you or not without seeing it firsthand. in general i would have to say that both my sony tv (older ccfl model) and my uncles sony (cheaper led model) are great so i would expect the sony you picked out to be nice as well but that is for your own eyes to decide.

i will say that the sonys have good build quality and have replacement parts available should there be an issue in the future which is a plus. a relative worked in the tv repair industry and always stressed how easy it was to find parts for sony but how impossible it was for most brands like olevia, vizio, etcetera.

the one thing i did notice which i didnt like was how a reviewer said that aftermarket wall mounts would not work with this model and how the base doubled as a wall mount. i'm not so sure how true this is as many wall mounts (well at least the good ones) come with all manner of spacers and adapters to make just about any tv work. who is to say that some company didnt make one to work with even an odd wall mounting hole pattern. this is just something for you to look for before you decide. most televisions and monitors use a vesa mounting hole pattern as a standard which makes picking out a wall mount easy. again... do a little research on this first before you select this model.

most 200hz tvs have game mode built in however not all of the game modes actually work that well... ie they still lag. this is why i suggested a working game mode. the best way to test would be to hook up a game system to it in person but you could manage to just read a bunch of reviews (where people are hooking it up to a pc for gaming or a console for gaming) to see if you hear any mention of an issue.

while it may sound like i'm knocking down that sony model... i am not. what i am saying is that even though it looks like it might possibly work for you i'd really like you to see it in person first and do a little more research on it.
