LCD backlighting - this is what it looks like

Ummon:

This is a CRT with, I'm guessing, the brightness or/and contrast turned up too high - although my Dell trinitron looks like this all the time, but I don't use it for Mame games, especially not black-background golden age games - and this is what LCDs look like all the time.

ark_ader:

With the brightness and contrast hiked up, yes.

My eyes cannot stand the glare, so I invest in a filter and bring the settings down.

TOK:

The blacks and response times are definitely a weakness on LCD's. Pretty easy to find 2ms small LCD panels now, so the display speed isn't much of an issue. Using a tinted bezel helps the black issue immensely. This is my LCD panel with 20% tint.
Its in a bartop where LCD's make the most sense.

Looking at that picture, I can still see it though. (re: ark-ader) I'm fussy that way. However, my point in this thread is to show people what it actually looks like via this example and what to look for when looking at an LCD in contrast to a CRT. They can then decide whether they like it, wanna deal with it, etc. (This also puts to rest the discussion of 'LCD backlighting'.)

@TOK:
Don't know how you took that picture, but the histogram only uses the darkest 10% of the spectrum, so either the camera or the photoshop killed quite a bit of dynamic range. If you stretch it too full dynamic range, it more looks like this:

So ask yourself how true your image is compared to what your eyes see. Try to make an image with a nice full historgram from black to white, and then show it.

I did lots of research on the LCD thing, and if this is a TN screen this picture cannot be unaltered.
Dark tinted glass does not help as the contrast stays the same. The problem is the brightness of the backlight. The best thing to have for a cab is environment-light-adaptive backlight. Eizo puts it in their screens I know. Do not confuse it with dynamic contrast, which adjusts contrast based on the image. Because of this light sensor, the black in my screen is always adapted to the light in the room. I think the contrast is better than with CRT. You might see some black-leaking, but the white is much brighter too!
