I can assure you that your argument about video resolution and screen size is completely irrelevant. Hence the reason my Galaxy Nexus resolution looked phenomenally better than my Droid 2 and the same reason my S4 video PQ looks even better than my Galaxy Nexus.

...and that's only a 4.65" screen held at a max distance of 18 inches.

It is absurd to argue that it is OK for Chrysler to cut corners simply because the screen size is only 7ish inches and only 24 inches away from your face when can buy a 7 inch 1900x1200 IPS screened tablet (Nexus 7) for $229 at your local Staples. $499 at the same Staples store will get you 2560x1600 10.1" that I can assure you, looks far more impressive than even the 10.1" screens than were available 18 months ago.

Again, simple laziness is the only excuse Chrysler has. They could have installed seat mounted Samsung tablets, and it would have been far more groundbreaking than their half-assed attempt.

Sorry...but no. It may have looked better because the graphics engine was changed or different, or more likely because you thought it would look better (confirmation bias). Slightly better, perhaps...not "phenomenally" better by any means. Your eye can only pick out so much detail at the distances given. Look closer, and sure...you can begin to discern more differences.

Oh....and for video, display speed (pixel update rate and response time) is FAR more noticeable than resolution on these scales. THAT may well have been what you were noticing more with your various smartphones, rather than resolution in and of itself.

Re: 2014 Durango - Features and Changes

Whatever you say. I know what my eyes see, and the clarity (even on still pictures) on my Galaxy S4 is better (hands down) than my Galaxy Nexus.

Yes, my kids will notice that Up (would never let them watch Sponge Bob) looks very different on their 7 inch screens at 20" compared to the 55" inch at 48" away in our family room.

Apart from that fact, the one that would have paid for it (me) will know that he got duped out of $1800 for $400 worth of tech that was touted as a major feature upgrade.

Well, coming from an engineer's perspective I'd say marketing is working well on you

Well, hmm. Okay, I'll tell you what. Go buy that run of the mill set of commercial displays in a store and put it in your vehicle. Then, let me know how well it works in the temperature extremes your vehicle will be exposed to. You ARE aware that small high resolution displays perform very poorly when exposed to cold temperatures right? And you're aware that standard commercial grade displays will basically eat themselves if exposed to the hot and cold extremes that will occur in a vehicle right?

While I certainly believe cost has something to do with the display choice, you aren't factoring all the information in before getting all bowed up. These displays are more expensive to begin with as they have to be rated to wider temperature ranges (and trust me...that shoots costs up quickly). Most are also rated for vibration resistance.

But the point is, there are LOTS of differences between any 2 display technologies. Everything from panel type, backlight technology, color calibration, refresh rate, and even screen coatings. And in all likelihood...those are the differences that make a "hands down" difference in image quality at the screen sizes and resolutions were talking about.

Hence, why you can go into best buy and see two different TVs with the same resolution and size and one having a vastly superior image vs the other.

Note, I'm primarily talking about images and movies here. Resolution will have a much more noticeable impact when thinking about reading / web browsing, etc.

Its much easier to market resolution though ( more pixels) than it is to market higher quality pixels. Same goes for imaging/cameras.... More megapixels are better for certain things, but other factors are a bigger contribution to overall oicture quality.

Well, like factory navigation, factory entertainment is rarely a good "value" from a pure tech standpoint. I value the built in OEM convienece and integration into audio system. Others don't.

That all being said, these display panels' quality might be crap, stellar, or somewhere in between. If they're crap, it will be because of other choices that were made, not particularly the resolution.

Jury is still out...

Page 37 from Durango media book I picked up at NYC Auto Show says the following possibly conclusive information: "Mounted on the back of the front seats is an available all-new class-exclusive Blu-ray video rear entertainment system. This new system features two high-resolution 9-inch screens, one on each front seat back. Each screen offers four-times better resolution when compared with previous models and allow customers to watch their movies on Blu-ray or standard DVDs or play their high-definition media interface [HDMI] gaming systems via inputs for HDMI cables or RCAs for each screen integrated into the front seat backs. Wireless headphones are included as is a wireless remote."

Wow, I assumed "two high-resolution 9-inch screens"+Blu-ray+HDMI= High Definition monitors. Goes to show, never assume. Now to calculate if QVGA to VGA equals four-times better resolution. 320x240x4=640x480. Yes folks, the Durango comes with two 9-inch VGA screens with 4 times better resolution than QVGA. Shhh, don't tell the kids, they won't notice. And don't tell the spouse either that I spent $2000 on two VGAs. ...Hey spouse, they came with remotes, headphones and are resistant to extreme temperature differences. :'(

On the bright side, if I add my future two screens together they equal exactly 2/3 the pixel count of one 720 HD screen (640x480x2)/(1280x720)~.67

Well according to Lechner Scale (coincides with THX results), the optimum 720 HD resolution from a 9-inch screen is in fact about 2 feet. So maybe resolution does matter. Your visual perception arguments hold much better for 1080 which drops to 1.2' using THX scale. Probably best to let the little ones just look out the window (assuming not nighttime) with all the objects at much higher scale. ;-)
