Flux - or how to make your LCD like an E-ink screen

carthoris · 09-13-2011, 04:59 AM

Hello. you know that Eink technology is claimed to be how the future generations are going to read.there a great deal of discussion about the benefits of an eink screen vs. a backlit LCD, in regards to eye strain because staring at a PC screen is less comfortable than looking at the eink screen or paper even after we adjust the brightness intensity down to lower levels. Flux is your answer, and it's free. anyone heard or use it?

Let me know what do you think.

Heard about it, use it. This doesn't make an EInk screen out of your LCD, however. All I can say about it is that it does make looking at an LCD screen more comfortable later in the evening, but still, you don't get the contrast EInk gives you. Neither do you get the battery life, for battery-powered devices.

Also, since this has nothing to do with Calibre, I'm moving it to an appropriate forum.

No, I've never heard of it. Sounds interesting, thank you for pointing it out.

And, carthoris, welcome to MobileRead!

Question back: Are you in any way affiliated with this program?

F.lux adjusts the apparent color temp of your LCD display to correspond to the outdoor sunlight for the given time of the day in your part of the world. I have used it for years as I am on a computer for 10-20 hours daily and feel it can't hurt at least add that sort of thing to help my eyes and relaxation. DOn't know if it really works but I don't believe it will hurt.

It also lets you manually adjust the apparent backlight temp so it is the same all the tiime as well. Very handy utility.

I can say I do notice an improvement in my eye fatigue at the end of the day when I am running F.lux. And hey, it's free.

Flux is fairly cool. I like the concept and it's rather easy on the eyes.

Nexutix · 09-13-2011, 11:17 AM

Like E-Ink? No. It reduces "blueness" on the screen.
I started using F.lux a month ago. Changed my life. My eyes don't hurt anymore.

Jacquelyn Smith · 09-13-2011, 11:43 AM

I've been using F.lux for a few months now, and I definitely notice a difference for nighttime computer work.

While it has nothing to do with making your screen look like e-ink, it could be cool for toning down the kelvin at night before bed. Seems simple and decently crafted. tryin it out.

pendragginp · 09-13-2011, 01:57 PM

That's a great idea! Going to give this a try.

afa · 09-13-2011, 02:30 PM

Never heard of it before. Just downloaded and tried it out right now, and I already think it's great.

Thanks for the recommendation, carthoris.

I used f.lux for a couple of months but ended up not liking it and uninstalling. I didn't like that the brightness of my monitor varied with the time, I didn't like that the brightness changed while I was reading it,...and I ended up not liking that my monitor seemed dim a lot of the time.

pendragginp · 09-13-2011, 09:31 PM

I've tried it now - LIKE. =)

Ouch. It breaks color management profiles. Every LCD screen, deskktop or laptop, generally has massive blue shift. Everything is overly blue, with reds and greens washed out. You can fix this by either calibrating your monitor (expensive, time-consuming, but the best option) or finding an icc profile from someone with a similar monitor who's already calibrated and using that. However f.lux resets back to the monitor's default. That's awful.

Edit: I tried the Windows version. According to the "recent updates", the OS X version actually respects color profiles. The Windows version quite obviously does not. So maybe this would be decent on a Mac, but it's unusable under Windows.

Does anyone know if the Linux version would work on an Android tablet?
Or if there is a comparable app for Android?

I tried hard to find anything like it. Nothing (yet) exists for Android or iOS devices.
