My mac mini 2011 can not set 720P through HDMI

I have the same mini and have tried it on an LG and a Sony HDTV with HDMI.

If you have another monitor that you can plug the mini display port into you should try that and then connect the HDTV. Then check system preferences to see if the TV is recognized . If so you can then try different settings in the display settings.

For one thing, the mac mini in display settings does support 720. HDMI to HDMI works fine. Try shutting down the Mac mini and then turn the TV on with HDMI to HDMI and once the TV is on then try turning the Mac mini on. Unfortunatly some TVs do not work as a monitor. Make sure you have it on the right HDMI out put on TV.

Wrong!!!! The Mini will set the display to any display

format, be it 720p,1080i,1080p. I have mine set to 1080p!

The issue here is that for some reason the Mini is not getting

the correct display information over HDMI.

Do have multiple HDMI ports on the TV and have you tried

different ones?

Also, try zapping PRAM.

Resetting PRAM and NVRAM

1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.

Make sure the TV is on before doing this.

You are connecting DVI to HDMI? If that is truely the case,

then you will only see computer type resolutions. You need to

connect HDMI to HDMI to get the HD type resolutions.

Yes ,I have a Lg l226wtq monitor, when I connect it to Mac mini from dvi to hdmi interface, it work fine. I can change display settings, but it have only 1280* 800, 1360* 768, 1024*768, 1280* 960 ets . My needed item 1280* 720 is not exist. (Sony HDTV klv32bx205 need 1280*720, 720p only) .

.if i use another pc in windows os , i can set 1280*720 to monitor.

I have no apple keyboard, I hope Mac os lion can set any display settings like windows os.

I feel Mac os is not so good.

While the official HDTV standards are either 1280x720p or 1920x1080i or 1920x1080p very, very few TVs have a physical resolution of 1280x720 pixels. Most so called 720p TVs actually have a physical resolution of 1360x768 (or thereabouts).

So, if you are detecting and getting a choice of 1360x768 this is what you should use.

This strangeness of 720p TVs really, really annoys me. No video exists at 1360x768 pixels it is going to be 1280x720 or 1920x1080. If you show that 1280x720 on a 1360x768 screen it has to be enlarged to fill the screen or you will get big black borders. If you enlarge it to fill the screen then the video pixels do not exactly match the physical pixels reducing the sharpness of the image.

Note: if a computer with the same TV is detecting a choice of 1280x720 then this is almost certainly being scaled by the TV itself up to the physical resolution of 1360x768. It is unlikely to mean the TV has a physical resolution of 1280x720.

Ironically, most people with a so called 720p TV which has a real physical resolution of 1360x768 find that they can only detect 1280x720 and in reality would get better results if they could use 1360x768 since with a proper 1 to 1 match you get sharper text from your computer for example.

Of course the samething applies trying to play a 1280x720 video on a 1920x1080 screen but at least you have the possibility of playing 1920x1080 video at a 1 for 1 perfect match.
