PC monitor LED or LCD?? and a little fast guide for buy one????

LCD is so 2005. :p

LCD and LED are not different things, most modern LCD monitors are LED

LCD is the screen technology, of the pixel groups and LED is the backlight technology, behind the LCD screen... Then are most LCD of the VA type (that often give best black, but work also best if you sit right in front of the screen) and many are of the ISP type, that not give very deep black (except some from Sony) but instead work fine even from an angle...

what you should be looking into is panel technology, VA, IPS, TN and Samsungs own panel tech

IMO there are 3 mains things and 2 small things you should go for in a monitor. Depending on your budget you might have to sacrifice some to get others.

Major stuff:
1) screen size -> First You should decide on the size of a monitor, bigger is more expensive. It is usually described in inches, Like 27'. This is the diagonal size of the screen.

IMO you should choose the size you prefer as longa s your budget allows.

2) Resolution -> this means the ammount of pixels the screen displays. Higher is better but it is also much more taxing on the GPU. It should be represented by the number of vertical pixels; for example 1080p, 1440p and 2160p. Unfortunalty most laymen found it complicated so brands use key words for those numbers: full HD=1080p; 4K = 2160p.

IMO due to your GPU being on the weak side I'd recomend a 1080p monitor;

3) refresh rate -> this means the number of images the screen shows per second. The higher the number the more natural movement will be on screen. Most monitors use 60Hz, 120Hz or 144Hz. DO note that many TV screens and some monitors say they have 1000Hz, it is a lie. You should always use an independent site to verify what the manufacturers says.

IMO it all depends on the games you play. Consoles render games at 30 FPS so a 60Hz monitor is enough for those types of games. IF you play twitch shooters going for a 144 Hz might be interesting.

Small stuff:
1) variable refresh rate -> G-sync is a technology that stops screen tearing. It highly increases the prices of a monitor but it might be for you if you play games with a high variance in their FPS

2) Contrast/colors -> some panels have better contrast/colors then others. If you work in art it might be interesting to take this into account. If it is just for gaming i'd use the other parameters to choose the monitor.

Most other things that are on the box don't directly affect gaming. for example angle vision is meaningless for us since you are probably right in front of the monitor.

TN < VA < IPS (panel type) for color quality. I've used all three -- TN colors look washed out compared to the others. VA is better, but a good IPS panel will give you the best color experience. I'd recommend heading to a shop that sells the various panels and check them out for yourself so you can see the difference. If you do any sort of photo/video editing at all, a good IPS is the way to go.

1MS or 20 MS (response time) -- lower is always better. It's how fast the pixels can change color. The higher the response time, the more likely you're going to notice "ghosting" in moving images. VA is the compromise here. You get the good color quality and can get a 1ms monitor, whereas IPS is usually 4-6ms or higher.

this monitor have 150º angle vision and this 180º -- Viewing angle is fairly irrelevant if you're the only one using the monitor and using it head-on. The least meaningful spec, imho, and really only useful when purchasing a television (which would be more likely to be viewed from different angles).

this monitor have HD 2K and this have HD 1K -- Resolution -- again, higher is always better but (and this is a big but) -- don't get a monitor your graphics card can't push. 1080p (1k) is pretty standard, but 1440p (2k) is becoming more usual now, and 2160p (4k) if you have a powerful graphics card.

One spec you neglected is refresh rate, and it's one of the most important. In layman's terms, it'll end up being the maximum framerate you'll get when gaming. 60Hz (which translates to 60fps maximum) is most common, but 120 or 144Hz is preferable for the best and smoothest experience when gaming.

Size - bigger is better. 24-27 inch is pretty common these days.

Last bit of advice -- splurge more on your monitor than you might on your other components. Chances are your monitor will be around for a while, sometimes much longer than your other components, so get one that you won't mind looking at for a few years.

So finally after all your help i have an idea of what i should buy. and i will try to aim for that

-Price 150-200$ Euros spain price
-LED
-VA (not IPS because my budget don't have for a good one, and the user of above told me is better VA than a "crap" IPS)
-angle of vision 160ª +++
-color --> idc anything will be good isn't something too relevant, at this point any of 150$+++ will have enough colors for gamming
-size of 24" (not 24.5",or 23"... nope!!!! will be 24")
-16:9
-Full HD or HD (it's the same) i will skip the 4K (that will give me more movement when i buy my new PC and more duration at max graphics when new games come out)
-HDMI (my graphic card use it and i will need one so.....) actually i'm using a convertor of signal to make it run with my obsolete broken monitor (who knows if that convertor killed faster my monitor xD maybe that convertor it's a killer monitor!!!!)
-60HZ (if i see at good price something better like 144HZ i will get that but i don't see any of 144HZ lower than 250$)

thanks to all the help guys!! now i understand a lot better how to buy a good monitor. so i expect to buy something how i told, even if the shop don't have any similar at least i can improvise a bit now!!!

Trinitron \o/

here are the best monitors for the prices, divided by features
