How would I know if my lcd-display is TN or IPS ?

is IPS so expensive that surely I would know if I had bought one? :)

asus.com/Commercial_Monitors_Projectors/VK246H/#specifications

well, that was one useless link, Asus is not revealing their secrets ^^

Asus VK246H hdmi

it is cheap, but looks better than its price tag would suggest ;)

It just hit me that when we get new questions that are similar to several others, it might be a good idea to link to a search using the right keywords to get good results.

bought myself a used Canon 28mm f/1.8 USM today - looking forward to testing it this weekend

@EsaPaulasto tftcentral.co.uk/panelsearch.htm

you have a TN panel

but yeah, in general, while prices are coming down, you are still likely to know if you got a S-IPS or S-PVA

though high end TN panels can cost more than a low end S-IPS potentially

you can also tell just from looking off angle at your monitor

if all your colors go funky

you don't have a S-PVA or S-IPS

apparently your monitor can have panels made from different companies either/or it isn't known which one specifically makes it

there are only a few companies that actually make display panels

atleast in large quantities

so a lot of monitor manufacturers actually use the same panels

my HP monitor for example uses a Samsung S-IPS display

@HåkonK.Olafsen nice, I still have yet to buy a prime. I know I should, if only to try one out, but my entire lens budget has been going in to nice zoom lenses

I am pleased with the angle issue, colors change only so very little inside 90 degrees (+\-45° from center) and beyond that only colors change but not brightness.

yeah, brightness doesn't normally change significantly

reading about the number of bits used is what woke me up to ask this.

the light just gets defracted wierd

basically TN works by having two opposing polarized filters that normally block light, the TN pixels then rotate the polarization of the light to allow it to pass through at variable levels

hence the twisted nematic name

been quite happy with the monitor so far, and it will require some serious self-justification before I can make myself to buy a new one.

a side effect is that at angle, light on one end of the spectrum or the other comes through at that alignment

in plane switching and patterned vertical alignment can avoid that by making a clean block of the light, but require much more advanced pixels

but they also give greater control over the bit depth available

and the color change may not be significant, but it typically does have an impact on fatigue and cause trouble with color correction. When you are trying to judge the difference between one color and another and there is actually variation from one side of the screen to the other, it's a problem

but until you get some more experience in color correction it probably won't become a significant problem for you, though you'd probably already notice the difference

yesh, the angle of view is a no concern to me, Asus has done good work. But now I know what to look for when I'm buying the next display. Thanks :)

I came from high color accuracy CRTs and didn't have a choice other than to start out on S-IPS when I finally was forced in to LCD screens

people thought I was nuts lugging a 50 pound 19 inch CRT to conferences with me

Hehe, conferences... new way to call those LAN-parties, perhaps?

Been there, done that and loved it :)

@EsaPaulasto no, these were actual conferences that I was doing A/V work at

I've worked 2 to 4 conferences a year for the last 13 years or so

My 19" CRT weighed a bit over 20 kilos, not far from 50 pounds I think

I had an A90f+

I do like my HP 2475w, but I still miss the vertical resolution and brightness of my A90f+

but I do like the size and horizontal resolution of my HP as well as the added clarity from digital addressing

but it cost me $600 to replace a $150 CRT

and even then there were still some gains and some losses, though I think they roughly balanced out

though if my A90f+ still worked, I'd probably still have it hooked up as a secondary monitor

I liked my Nec a lot :)

Though it did break down after 2 years. Got three years on-site guarantee on it, but after 2 years they did not have this model anymore.

so they offered me one of their tft displays instead.

yeah, silly environmentalists not wanting to have all that CRT pollution :(

This was years ago when tft was not yet too good at colors. And the model they offered was at cheapest end...

so I told them 'Not interested! I chose this CRT for its good color space and this tft you offer does not come even close!'

So, they had to take it in and actually repair what was broken, lol

Took their time with it too, three weeks, and the "on-site" part really had only one transportation included. They would not retrieve and bring back. So I drove 100 miles to the repair shop to hand the tube in. And they brought it back after the fix. Such "on-site".

I'd say, after the years of use deteorating the CRT, you would not have it anymore. See the difference between 'rn' and 'm' clearly? Yes you do. But with a years old CRT it is no longer so easy to tell rn from m.

@AJH thanks for the tftcentral link :)

HPmakes a decent cheap IPS screen. reviewed on tftcentral

I'll find a way to drop the Asus and accuse our cats for it ;)

I found an answer to a question that was not asked, but which helped me understand something :)

Olin Lathrop's answer to photo.stackexchange.com/questions/23606/…

And seriously, not going to drop my display just so. It is good enough for keeping its life, but I'll need to follow those advices given how not to burn my sense of color. And later, when this display grows old it will be time for proper color display.

@MichaelNielsen yes, the HP 2475w

that's the one I have

:)

it's still around $450 to $500 currently though and was $600 when I got it

Done for the day. Once again used all 40 votes.
