Default Some Games/Apps running at lower resolution on my Nexus One compared to my Streak. (56K warning)

Really sorry for all the screenshots.

I own a Nexus One and Dell Streak and one thing that I find disappointing is that some apps don't run at the native resolution on the Nexus which makes things look blurry compared to my Streak.

Examples: (all screenshots taken with the Android SDK)

ExZeus:
Nexus:

Streak:


Speed Forge 3d:
Nexus:


Streak:



Here is the Engadget app on both devices:
Nexus:

Streak:

I initally thought that due to the huge difference in screen sizes the N1 may "blow up" the image to look bigger but it seems that Gameloft games run at the native resolution and look fine on both handsets:

N1:


Streak:


Now, I understand that the PenTile display will have an effect on image quality Vs my Streak but why does the N1 seem to be rendering things in a lower resolution compared to my Streak?

Any ideas?

Dell Streak Resolution: 480 x 800 pixels
Nexus One Resolution: 800 x 480 pixels

However, AMOLED displays are different than your traditional displays:

When we read tech specs for products released by large, reputable companies, we tend to take their word for it that they’re being honest. I mean are we REALLY going to grab some tools, shimmy open the device, and make sure we’re getting what we paid for? No.

Well…. maybe some of us, but that’s not the point. When you read the Nexus One screen resolution was 800 x 480 pixels it was a selling point, and chances are you weighed that as a factor when making your purchase. Well a report from Luke Hutchinson of Ars Technica is claiming that the effective resolution of the Nexus One is actually much lower – 653 x 392.

How is this possible? If you want the full tech-heavy explanation you’ll have to read the entire article, which is definitely deep to say the least. I’m not saying the story is accurate or inaccurate – and Google has yet to comment on the issue – I’m just letting you know the opinion is out there. I would ASSUME that the Nexus One does support 800480 pixels resolution, but the AMOLED technology utilizes those pixels in a different manner to accentuate brightness over clarity.

The Nexus One screen is based on the “PenTile subpixel layout” which Hutchinson explains in great detail. He raises the following question, which seems to be the anchor of his contention:

Quote:
Even though no single pixel contains all three color elements, is it legit to say this display has 480800 pixels as claimed by HTC and Google?
I think it is absolutely fair to say. The pixels are there and they exist – nobody ever told you what was going to LIVE in those pixels, right? And Hutchinson admits that the hardware resolution is indeed accurate (800 x 480) and that he is challenging the “effective resolution”. In fact as Hutchinson explains the blurriness of the pixel discussion itself, you start to realize he isn’t claiming the Nexus One pixel specs are misleading, just that the practice of how pixel resolution is quantified is – as a whole – fuzzy business.

This probably isn’t the last we’ve heard of this, because according to CEO of Nouvoyance – Candice Elliot – values can be tweaked in the PenTile display driver hardware. And if something can be tweaked in a display driver, rest assured there are modders, hackers, and software engineers who will use that as their own personal playground.
The N1 is Beautiful, no doubt, but if dev's don't take things into account like this, it's not going to look good across all devices. Gameloft makes their games as "HD" games for the N1 and take this into account for devices with AMOLED displays.

Hope this clears things up a little.

Good point Talderon. I forgot that the Gameloft HD titles were designed for 800x480 displays!

It does puzzle me that the N1 is capable of rendering games at 800x480 internally and they display fine on the display (albeit a little blurry due to the AMOLED as you mentioned) but some games like ExZeus seem to be rendering noticeably lower rez on the N1 (to me at least).

I still think my N1 is the best phone I have ever owned tho. Awesome phone, especially with FroYo!
