Default LED monitor - er no, it's LCD with LED backlighting. Looks rubbish?!

Hi all, just bought a new LED monitor for my PC. Now it has arrived it says on the box that it is an LCD screen with LED backlighting.

I hadn't understood at the time of purchase that it wasn't a straight LED screen.

Now it is up and running, it looks RUBBISH

The colours at the bottom are too washed out, or those at the top are too dark. Trying to change the height or angle of the screen to improve things only results in either the top or bottom looking OK and the other looking extremely washed out or extremely dark.

With a solid colour displayed to fill the screen, it looks different shades in different places.

To me this looks like a typical LCD screen from a few years ago, and I thought nothing of them then - this is no better, despite saying 'LED monitor' on the box. Seems to be a dodgy description (but allowed by the ASA) to fool people like me into buying it.

I suppose a 22" LG LED full HD monitor for £76 delivered was bound to have a catch.

Does all this make sense and sound about right? I'm going to see if I can compare it to a small LED TV (if the latter has a VGA input) to check that a PROPER LED screen will display how I was hoping.

Very unhappy about this monitor, my old year 2000 massive Iiyama CRT had a far far better picture!

Any thoughts/opinions? And can anybody please recommend a good cheap LED full HD 22" monitor?

Thanks

Had a very similar problem with a small TV I purchased for use in my caravan. Basically, it is only watchable if I stand directly in front of it, with my eyes on the same level as the screen. Outside those constraints, it might as well be a blackboard.

OK, another 5 mins quick reading and it looks like LED TVs are actually LCD with LED backlighting, just like this monitor. So maybe I have got it completely wrong?

Either way it looks awful. Any suggestions for something with a viewing angle like on an ordinary LED TV?

You've hit upon the truth there Colin. Flat screens are thin, very bright, large and trendy, but a CRT can display greater contrast range and can maintain high definition no matter how fast the incoming signal changes.

Correct. With the demise of the superior Plasma screen, there is now only one choice.

A good article here that explains the difference between LCD, so-called LED, and OLED sets if you're interested.

LG are usually excellent with their products.
If you can afford it take it or send it back for a refund and upgrade a little.

If you want a good quality "LCD" type monitor display with good viewing angles, colours and contrast, you need one based on a good quality IPS panel (not cheap IPS panel either). It will be as good as an IPS panel from around 2003 but will cost significantly less.

Monitors described as LED are generally TN panel LCD with LED backlighting rather than CCFL. In other words, cheap and relatively low quality.

Quality still costs - expect to pay £200+ for a good quality 24-inch monitor.

A Dell Ultrasharp Pxxxx or Uxxxx monitor will be very good.

CRT Monitors were and still are the best, the problem though with CRT monitors are:
Convergence issues.
Size and weight.
If you can find one.

I use a Sony 32 inch TV in the shed which is a 110v US set, It is an LCD but has first class angular light levels and definition, far superior to any Sony set sold in the UK as it must have been a top model.
There is a lot of junk out there but I have seen some really nice monitors too, I'd agree with mss believe it or not that Dell do buy in good monitor chassis and screens.

One (more) technical area where the marketing is highly confusing for people. A so called 'LED' screen differs from an 'LCD' screen only in the way the backlight is generated. Early LCD screens had a single backlight along the bottom edge of the screen, later had backlights at the top and the bottom. This leads to brighter at top and bottom than in the middle. So-called LED screens using LED backlighting evenly distributed behind the LCD panel. The ratio of LED to LCD is a good determination of the possible contrast quality of the screen as these LEDs can be individually controlled to vary the brightness of different areas of the screen.

usable viewing angles are determined by the quality of the LCD and any mask over it rather than the back lighting. Best advice is go and view some. Find the ones you like in a bricks and mortar store, and then go search for the best price online.

If you have ever repaired a LED backlight LCD TV or monitor you'd realise there is far more to it than that.
Between the LED's and screen there are numerous polarizing sheets which have to be replaced the correct way round and in the correct relationship to each other, get it wrong and you can have reversed colours, lack of luminance or poor black level (No proper black level anyway on an LCD)
LED failure is common and its usually caused by the default settings which usually has the backlight at maximum, reducing the backlight to 75% and then adjusting the contrast and brightness to give the best ratio will make your LED's run cooler and greatly increase reliability.
