I've recently bought myself a slimport adapter so I can hook my g pad up to a TV (1920x1080).
The g pad appears to downscale its native resolution of 1920x1200 to the resolution it outputs over hdmi (in my case, I'm outputting 1920x1080).
As I'm displaying movies on my g pad's screen @ 1:1 aspect ratio, this downscaling from 16:10 to 16:9 obviously leads to distortion.
To remedy this, I'm using "wm size $resolution" to change the g pad's resolution to 1080x1920.
The problem I'm having is that the window manager is doing some stupid stuff with the virtual softkeys in landscape mode at this custom resolution.
See screenshot here:
@ default 1920x1200
@ 1920x1080
Does anyone know of a solution to this problem?
How do people successfully use the g pad's slimport to hdmi functionality when the TV is a different aspect ratio to the device?
I'm still stuck on this; is this a flaw with the stock rom for which there's no known solution?

You have to change dpi settings too. Can see instructions here or use Resolution Changer Pro from Play Store.

Does anyone know of a trick or method to change or force a given resolution for the display output via MHL?
I ask this because it appears to default to the highest resolution available on a given monitor, but 1080p is gimped at 30Hz, which is extremely bad. If I can force the adapter to display at 720p 60Hz at all time then that would be awesome!
I originally have a Note 8.0 but also use a friend's note 2 sometimes for giving video out to a Projector. So, I use an MHL to VGA Converter and a 5pin to 11 pin adapter.
The problem is that both the devices randomly pick a resolution everytime I connect it to the projector. Sometimes 720p, sometimes 4:3 VGA. I just want to fix on a resolution. VGA only rarely comes up, but I actually want it because the projector is natively 4:3 and fills up the screen better with it.
Is there anyway I can select the VGA resolution permanently? Like selecting a resolution in Windows?
I found a libhdmi.so file on the Note 8.0 which contains all the info. About resolution, it has everything from 640x480 to 1080p modes. Is there anyway, I could modify it to get the same resolution all the time?

So when using the Slimport adapter with the Nexus 7, the 1920x1200 16:10 image is scaled down to a 1728x1080 16:10 image.
The 1728x1080 image is displayed on a 1080p 16:9 TV with black "pillars" on the left and right sides.
For me, this is completely undesirable.
I am hoping that there is a custom rom out there that offers more slimport output options.
Such as:
-Changing the Android workspace to 1920x1080. Letter boxing on the tablet and pixel perfect on the TV.
-Changing the Android workspace to 1920x1080. Vertical stretching on the tablet and pixel perfect on the TV.
-Retaining the Android workspace at 1200p. Vertically squashing the TV image to 16:9 for a 1080p image with distorted aspect ratio with no black bars. (distorted AR can be reversed with many Video player apps and Picture viewer apps).
Any of those is more desirable to a 1728x1080p pillar boxed output. Any help on the issue would be greatly apreciated.
I've posted a feature request on google groups, asking them to consider adding more output resolution options to Android. http://productforums.google.com/forum/?hl=en+#!category-topic/mobile/android-devices/cgKZEwu4CZg
Downscaling 1920x1200 to 1728x1080 involves un-even averaging of pixels on both the horizontal and vertical. Out of the many other ptotential options for display output, this has to be the worst.
I agree with you guys, there should be a better solution.
I have a 1920x1200 monitor, which is perfect for 1:1 direct output, but the N7 2013 still output at 1728x1080. It does not look good, especially when watching videos. The downsizing also causes a visible performance drop, there is a slight lag when interacting with the UI.

Awesome, thanks!
I have a nice 1080p projector I'd love to drive with the Nexus 7 over Slimport. Performance is great, but the picture has letterboxing on the left and right due to the 16:10 aspect ratio of the tablet. Is there any way to get the Nexus 7 to output only the top 1920x1080 (ignoring the permanent soft button bar)?

Yes, there are ways. Unfortunately none of them's easy. One way is to change the screen resolution but that requires root. The other way is to add support for external display in a video player app. As of 4.2 app developers are able to detect and handle mutliple displays at once. So it's for instance possible to detect that external display is attached, discover what resolution it supports and output video to the external display at a native resolution. I am quite surprised that the native video player does not support that. It shoud work by default that way.

Could you please tell me which slimport cabel you are using? is it SP10002? I am struggling to get a perfect one
According to my TV, the output resolution is 720p. How do I change the output resolution to 1080p?

Since the phone's own native resolution is 720p and with mhl cable You only mirror the screen of Your phone, I think You can't change the output signal.
I guess...
But hey! Good luck! Maybe You'll find something! :good:
