I just got a USB to HDMI cable, or can be called a MHL cable for my SGSII, but the output resolution was only 720*480(not 800*480, not 1080P, not 1080i) after the phone had been connected to the LCD screen(the screen reported this information).
I tried to set the monitor to "Full Screen" mode, but it just upscaled the image, the resolution still remained at 720*480.
Anyone has any idea about this problem?
BTW, I'm using the SiyahKernel with the stock ZSKI3 ROM.
Thanks!!
Open up the video player, it outputs at max resolution.
It does this because the system UI is running at a low resolution, so it can't output higher.
Like you I was under the distinct impression when I purchased my GS2 that the phone would output 1080p through MHL. Sadly this has not been the case. I was wondering if I was forgetting some setting but based on this thread it appears I'm not.
Wouldn't have been a deal breaker but it's still too bad.

Let's be clear.
The phone DOES output 1080p through the onboard video player. Open up a 1080p video and try it out.
Using the Samsung MHL adapter, I can do 1080i to my 32" Vizio (the only HDMI monitor I have access to). I see this resolution even when not running the video player; i.e. on the main "desktop" and app drawer screens. Of course, that's upscaled, but it still looks pretty good.
The Vizio supports 1080p, but for whatever reason, the MHL adapter won't provide it. I haven't spent a lot of time on this, but maybe I'll take another look at it over the weekend.

I did try the 1080P video playback as soon as I got the MHL, but like I said, the resolotion which the LCD screen reported is only 720*480, no matter in what kind of UI or application.
I had a LG Optimus 2x few months ago, and the HDMI on it worked perfectly with the same LCD screen.
Actually i noticed some interesting things when playing with the MHL. As i got a Samsung P2770HD screen i got basically all the connections. When i plug the phone directly by the HDMI plug screen reports full HD resolution (upscalled ofc, wondering if changing lcd density could give this some smoothness), but when i plug it trough the same cable but with a HDMI-DVI converter on the end the screen reports a lower resolution, phones native one if i remember correctly (which looks actually smooth and not pixelated, but i think there were all the fancy monitor's software enhancements on).

I've got a feeling you got this instead. www.ebay.com.au/itm/3-FT-Generic-Hi...AU_MobilePhoneAccessories&hash=item2567cc3a59
Excuse me, but at a first glance i dont think such cable could give any output at all, from what i understand of the mhl protocol the signal is different (quoting wikipedia "Other than the connectors being used, no USB nor HDMI technology is being used. It is exclusively MHL signalling through the connectors and over the cable. Other proprietary and custom connections are also allowed."). Fortunately we got an easy way to know, Thread starter, does your cable have also the power connection? And do you use it?
I wonder in the Note outputs at 720p?

I see the HDMI output quality very poor
I believe it has to be related to software or cable/monitor hardware, because my stuff gives me full hd resolution. Maybe compatibility issues, as we are using mhl adapters?

what rom are you use ?
Stock, Kies supplied ki4 CF-rooted. Nothing fancy as u can see. Also my screen is a samsung P2770HD, which might be helping. As I posted a page before, I get low resolution when connecting to DVI trough an adaptor.

I use stock KI3 and you should test on some larger LCD 40-46"
When I finally get my hdmi - dvi - d-sub converter i'll try to use
Some of the projectors in the university, that might give interesting results. Anyone tried to use better lcd density values to compensate for the upscalling?

Also can be the cable. Some ebay cables doesn't support HD resolution.
When I use HDMI output (on a 1366x768 TV), on the left and right part of the screen a part is missing, like a side crop. Is it the cable's fault (not original)? I can find any hdmi setting at all.
bonus question: SuperOneClick v2.3.3 is the best rooting for 0.42?
Thanx!
Hey,
I might be wrong, but could it be because it outputs at 1280x720 which is smaller than your 1366x768 TV?
Or do you mean it cuts off part of the image?

As of my current understanding / testing when connected to a HDTV / monitor etc via MHL, currently the ONe x mirrors the screen, so you get 720p. It doesnt look all that good (I have tested on a few native 1080p Tv's, and some look better than others.
I would assume that the hardware is easily capable of outputting 1080p (rather than just mirroring the 720p screen of the phone ?)
Any Devs, or any opinions as to whether this is something that could ever be expected from HTC, or possible to add to a custom rom..
I understand that other lower spec'd HTC phones can output 1080p (even though their screen native resolution is lower.. - Sensation XL or Evo 3D - sorry not sure which one exactly..).
I have to be honest I was pretty bummed when I connected it to the TV .. I just sort of expected it would do 1080p out of the box....
Also I understand that Media link HD only currently offers 720p mirroring of the screen.. Does anyone know if this is likely to support 1080 (maybe wifi bandwith limitation ..)
the lower spec phones i.e. the evo 3d that i own will only output 1080p at 24hz making everything laggy. also it doesn`t seem to be 1080p at all but simply upscaled by the tv itself. the images are not sharp at all but look fine from a distance. if i set the phone to output a 720p it will display at 60hz and image quality will be similar if not the same. if you look at the specs you will see that the tegra 3 cannot output to 1080p howver the tegra 3 + can. maybe a good dev will be able to help you out since i intend to buy a tegra 3 device too.

Could not stand still here but if you check nvidia's site it says that HDMI: 1920x1080 so it is capable of 1080p

Hey all , just playing around with my One x through MHL and noticed its only outputting at 640x480 @60hz !
It should be 1280x720 at least.
Ive checked on a few screens around my home.
I have this Adapter http://www.amazon.co.uk/gp/product/B007K8NN9U/ref=oh_details_o03_s00_i00
Anyone else have similar issues?
I wants Full HD's
There should be something wrong either with your MHL adapter or your software, its working pretty well with my ONE X and im getting 720p with no prob...
which adapter do you use ? I might just get a new one!
I use samsung Micro usb to MHL i used to use it with the galaxy note and S2
My girl friends sensation fills my 42" 1080p screen perfectly while outputting via MHL but my ONE X has borders the whole way round. It also does this on a smaller 720p screen.
Guessing its a Tegra issue.

Are you using a HDMI-to-DVI adapter by any chance? During connection handshaking, the phone queries the external display for 1280x720 60Hz, if not found, it will drop down to 640x480. You can use MonInfo the check your televisions's EDID info:

The CE mode IDs are what are being scanned, and you need to be talking to an HDMI port for this.

This is a known problem with One X unfortunately. It's shrinking the output image if the display has overscan modes, rather, it should be checking if the display has underscan modes and output 1:1 by default. I've submitted this issue as a bug to HTC, and am still awaiting a reply from engineering.
I don't believe this is a problem with Tegra, because the Transformer Prime will display full screen when the HDTV is configured for 1:1.
Ah thanks for the info. I'll will also mention this to them. Hope a fix comes out as its a PITA.
I'm also noticing that the image is broken up in to lots of mini squares when playing MKV. Perhaps this is MK player rather then MHL adapter. Anyone else noticed this?
The small squares look like bad image scaling , there almost overlapped. Circles look jagged etc
I'm using the official Samsung MHL 2.0 adapter that I bought direct from samsung.com due to all of the fakes out there. My main issue I've seen is with Netflix but I'm sure it happens all over. I'm using this on an older 720P TV but the screen does not fit exactly. The outputted picture is a little larger than the TV's display so it cuts off a little on the sides. It is not completely unwatchable by any means but still sort of aggrivating. I don't know how to change the size of the picture being output. DPI change? I don't know what size to make the DPI for a more appropriate 720P picture.
Has anyone else had any issues with anything like this? Any ideas? Thanks in advance.

This is probably just overscan which is normal for a TV (as opposed to a Monitor). It has to do with the fact that old signals/tvs were not completely reliable so they just snipped a bit off the edges to compensate. Roughly... Wikipedia has an article about it.
In my experience there is no easy fix. I've found that no matter what I do I either end up with a black ribbon around the edge or I lose some picture to overscan.

Solution. Get a 1080p TV. Haha. But seriously, you tried all picture settings on TV? If that doesn't work then more than likely you will have to live with it. I dont think DPI changes will fix it. And how the heck did you score a mhl2.0. I've had one in my cart for two months and it is still backordered. Ugh.

Lol your answer is more heart breaking than you can imagine. I have a glorious 60" 1080p panel that is in storage right now because I'm having some work done in the house so I'm using my old backup TV. But....I picked up the adapter right from Samsung for 20$ with their coupon from my note 3 purchase. I will try it on a 1080p eventually I was just curious if anyone had any ideas. Thanks for your input and I hope you get yours soon!
