About contrast ratio

[audiex]

hai, i decide to buy new monitor. i have 2 option, LG 23EA63V and ASUS VX239H.

both monitor are perfect for my choice which have frameless and IPS panel, also have matte for the screen.

my question here is does we need high Contrast Ratio for gaming and movie? because LG have 10M:1 and ASUS have 80M:1 which is more high than the LG one.

for LG price is cheaper than ASUS one. which one worth ?

Dynamic contrast doesn't mean shit. They will both look good. Just look at price/design.

Real contrast of an LCD is around 1000:1.

 

Those insane figures are of software controlled 'dynamic contrast' features and they are a marketing gimmick that should be ignored.

 

Do not factor those figures into your decision.

so LG would be better for me ?

Dynamic contrast means dynamically altering the backlight so darker scenes are darker and brighter scenes are brighter. For "backlit" LED screens the back light is dimmed in zones, which means that a bright scene in the middle surrounded by darkness can be lit separately, but results in a halo effect around the bright part of the image. An edge lit screen can only alter the brightness of the entire screen. My monitor can do this but I generally find there to be an up to half second delay which I find more distracting than the backlight bleedthrough the feature is there to hide so I have it turned off.

 

The numbers themselves are meaningless, but the feature is something you want to look at and decide if you like the idea and implementation of it.

They are both good. I don't know what their price difference is. I would go with LG since they probably make Asus the panel anyway.

Not entirely accurate, dynamic contrast exists in edge lit displays also, it's just software.

No hardware dynamic contrast exists, it just dims the whole backlight instead of zones.

Yeah I misunderstood your post at first, I thought you were saying that it only existed in zone lit LED panels.

I know it is software, I just wrote that because again I had misunderstood your post and had it in my head that you'd said specific tech was needed for the backlight. (Zone dimming).

In either case, dynamic contrast is a horrible feature which I suspect only exists to create those huge numbers to write on the box.

I dislike how manufacturers like to write meaningless stats on the box but never mention things display latency, you have to rely on third party test results to find out that information.

I dunno, some people find it an acceptable compromise and some people don't. LCDs are still lagging behind plasmas (and CRTs) in terms of real contrast ratio so I do think it's meant to be something to try and bridge the gap a little. Although bullshit terms like "mega∞" and fabricated ratios of millions to one don't help.
