Mockingbird Posted July 14, 2015 Share Posted July 14, 2015 I can read a book on an iMac (21.5-inch, Late 2013) for hours and hours, no problem. When I read a book on a Windows PC with a Dell UltraSharp U2212HM (with brightness turn up) for a couple hours and I already get a headache. I don't know what's different about them. They are both 21.5" IPS (1920x1080) monitors with LED-backlit. Link to comment Share on other sites More sharing options...
TAZMINATOR Posted July 14, 2015 Share Posted July 14, 2015 You can adjust the brightness on Windows PC or get f.lux and it will automatically be adjusted based on time of the day or night. You can adjust on your own in f.lux if you want to. Link to comment Share on other sites More sharing options...
devHead Posted July 14, 2015 Share Posted July 14, 2015 If I'm not mistaken, the iMac monitor is IPS, which is a very good looking monitor. I don't know about the Dell UltraSharp. You should compare the iMac monitor to another IPS monitor. Link to comment Share on other sites More sharing options...
Mockingbird Posted July 14, 2015 Author Share Posted July 14, 2015 I am not sure the built material, but the Dell looks like blurry plastic display, and the iMac looks like clear glass display If I'm not mistaken, the iMac monitor is IPS, which is a very good looking monitor. I don't know about the Dell UltraSharp. You should compare the iMac monitor to another IPS monitor. The Dell is also IPS according to Dell's website.

If so, it's LCD. I have Acer LED monitor that is clear glass with reflection all over. No ripple effect on it. Similar to iMac. I have 2 LCD monitors ... it can become ripple if you touch it with your finger. Link to comment Share on other sites More sharing options...
adam7288 Posted July 14, 2015 Share Posted July 14, 2015 Sir, LED is a form of LCD. It has to do with the backlighting. What a pet peeve! Link to comment Share on other sites More sharing options...

I am pretty sure an "LED screen" is an LCD screen with LED backlit. Link to comment Share on other sites More sharing options...
daorbed9 Posted July 14, 2015 Share Posted July 14, 2015 The iMac is a different type of IPS panel and is of the A++ grade so its pretty even color/light. Link to comment Share on other sites More sharing options...
TAZMINATOR Posted July 14, 2015 Share Posted July 14, 2015 I just touch screen on the Dell and got a ton of ripple, nothing on the iMac. Then your Dell is LCD. That's why it's not same as iMac. That's the reason you have headache from that. If you want headache-free reading on Windows PC, get a LED or OLED monitor.. Or you try the f.lux and that monitor and see if it helps... if not, get a new one.. On mine, I use the brightness down to 15 and I read fine these days. On 100 brightness, it hurts my eyes.

LCD: https://en.wikipedia.org/wiki/Liquid-crystal_display LED: https://en.wikipedia.org/wiki/Light-emitting_diode I like LCD better because no reflections on the display. I can use it any time of the day or night. I use LED in the dark room or low light as long as no light is facing at the monitor. If use it in day time, you can see reflections all over the screen.

I just looked at the spec of the iMac and it said 21.5-inch (diagonal) LED-backlit display with IPS technology; 1920-by-1080 resolution with support for millions of colors IPS is a type of LCD. You are probably thinking of OLED screen which is something different. Link to comment Share on other sites More sharing options...

I have Acer monitor which same as iMac. but I wish my Acer has same screen resolution as iMac. Both Acer and iMac have reflections on the glass.

Ryoken Posted July 14, 2015 Share Posted July 14, 2015 I donno about now, but for the longest time Apple Screens and Dell Ultrasharps used the exact same panel, only the Mac ones got the glossy finish.. Also, since Apple controls the hardware, you have to remember all the settings are optimized for it in terms of their display calibration. Link to comment Share on other sites More sharing options...

I can see my reflection on the iMac screen if it is bright outside. The screen on the Dell is matted and there's no reflection. I have no idea what's that call though.

Mine is matte as well, which is why you and I have ripple effects on the screen.. I don't have reflections on my 2 LCD monitors except the Acer monitor which is glass.

Draconian Guppy Posted July 14, 2015 Share Posted July 14, 2015 A plethora of things first and foremost, Factory color calibration Second would be hardened surface vs plastic one on dell / finish also helps if the display has a glossy finish colors will looker a bit more vivid vrs a matte finish. third better quality IPS display. Just because they are same speced, doesn't mean they use the exact same components. As others pointed out, refresh rate, etc. Fourth windows optimization in FONTS for lcd screens are notorious, google "clear type". both your monitors are led backlit, so that is not obviously not the issue. Are you reading in the same conditions? eg. black font over white background? Link to comment Share on other sites More sharing options...
Mockingbird Posted July 14, 2015 Author Share Posted July 14, 2015 Are you reading in the same conditions? eg. black font over white background? It's the same book, so I would sure hope so. Link to comment Share on other sites More sharing options...
LUTZIFER Posted July 14, 2015 Share Posted July 14, 2015 From what I remember reading, reflections on the screen have to do with they type of layers the manufacturer has used. But I could be wrong. My laptop screen is definitely an LED (and I know LED is still an LCD), and it doesn't hurt my eyes, nor do I get any type of annoying reflections on it, nor does it ripple when I touch it, and I can see it perfect in direct sunlight, etc. etc. The proper term for an LED screen is LED-lit LCD.

T3X4S Posted July 14, 2015 Share Posted July 14, 2015 I dont know, but I have a pretty good monitor - and looking @ the GUI on WIndows 10 makes me think about doing the unthinkable.... switching over to mac Link to comment Share on other sites More sharing options...
PaulATMOS Posted July 14, 2015 Share Posted July 14, 2015 I've always liked the glossy coating on the Mac screens. I wish Dell would offer the option of either matte or gloss. Link to comment Share on other sites More sharing options...
