Did you know ......

Greetings.

 

Did you know that monitors have truly terrible black level uniformity ?

 

I was searching rtings test results today, both monitors and TV's, and was reminded how truly disgusting the state of monitors, and smaller TV's are in currently.

 

You will not find ANY monitor on rtings list of reviews that scores over 7.1 in black level uniformity (of which there is only 1 that scores 7.1), most score below 5. (out of 10). The pictures linked with all these scores shows how truly horrible the uniformity is.

 

Grey uniformity 'can' fair better, but trying to match that up with a good black level score is very difficult. The best you can ask for is 6.5 to 7.1 on black with 8 to 9 on grey, resulting in a mere 6 results, and that's before filtering by ANY other spec, such as size, resolution, frequency etc.

 

Even some of the most expensive monitors available have truly terrible scores in certain areas, predominantly to do with picture quality.

 

 

Then we move onto TV's, where anything below 49" scores low on overall picture quality mainly due to poor HDR support and terrible uniformity across both grey and black levels. not to mention poor input latency and pixel response.

 

However, 'miraculously', as soon as you go 49" and above the scores skyrocket, with uniformity vastly better, usually better (25ms and below) input latency, and better pixel response. Results ofc have OLED appearing due to their availability being only above 55", but even the LCD offerings suddenly have far better quality.

 

 

As it is, if ur looking for a VDU below 49" that is actually 'good' at its primary purpose of displaying an image, then ur sod out of luck as there is currently nothing available.

 

 

 

Does any1 disagree? , does any1 have any examples of what they think is a good example of a monitor or TV below 49" in regard to picture quality, especially in regards to uniformity ?

I kinda scanned thru this post, but doesn't it make sense? Isn't a pixel a light? And a light can't produce BLACK light, can it? So even if it powered off to get as... "dark" as possible, wouldn't it still be affected by ambient light, glare, etc.?

I'm not well versed in monitors, it was the one component I didn't spend much time on, so I might be thinking about this wrong.

Thats more an issue with LCD's inability to produce pure black. Not really relevant to the issue of uniformity. Though it is a very significant reason for LCD's inferiority to CRT, Plasma, and OLED ..and pritty much any self emissive display.
