You have to click on the :apple: then software update while the adapter is hooked up to mac and monitor / TV.

Yep done that, and no updates pop up. Downloaded it manually and when I install it says it does not detect a mini display port connected, which is impossible as I am using my external monitor as I'm doing all of that.
 
just updated, didn't help with my wavy screen on my Sharp HDTV 3764U.

Some TVs don't fully support VGA or DVI even when it says so on the tech specs. Even using a DVI to HDMI adapter, the picture can look pretty bad because the Mac outputs 480p, 720p, 1080i or 1080p but most 720p TVs actually have 1366 x 768 pixels and do pretty bad at upscaling 1280x720. If you have a HDMI ínput that also says "DVI" on it (most Samsung TVs have that) use that, then your Mac can do all the scaling and output at the TV's native resolution. This basically gives you 768p which is especially nice when downscaling 1080p, viewing pictures or whatever you do when you hook up you Mac to a TV.

Couch computing (aka sitting lazily on the couch and doing stuff on the laptop) is so much better when you have a huge display and wireless keyboard and mouse. :p
 
Many schools are hardwired for VGA, at least several I've been to. Try to explain the benefits of DVI to many, and you will be greeted with a lot of blank looks.

True, when projectors came out, every school and company got a few, fixed it to the ceiling and put the cable through the wall with a convenient VGA socket on a convenient location. Few people are willing or capable to put another cable in there. Display standards come and go. Right now you'd need: VGA, DVI, HDMI and DisplayPort goung through the walls. :eek:
DisplayPort can actually carry each of those formats, but then people can't figure out the adapters and software...
 
And gives you more resolution, less interference and, in the case of HDMI, reduces cable clutter. ;)

oh it's great. I'm sold. In time it will happen, just don't get too surprised if money is a consideration before switching to a better standard.
(unless you volunteer to foot the bill)

Are you using a macbook pro? try switching to the 9600m GT graphics chip first.

The Sharp actually in PC mode has 768 on the tech specs which is what I am using. Besides 720p resolution is 1366x768 anyways. The wavy screen is not a wavy picture, but seems to be interference from the fan. The waving seems to be very noticable when the fans kick on past 3000rpm (according to istat) from the macbook..

It's a shame this sharp doesnt have a 1080p mode like my parent's sony tv :(.



I hope this can be fixed via firmware.

I don't know if this has anything to do with what your saying, but I also noticed some waviness on my HDTV (Samsung). I was able to fix this though by lowering the refresh rate from 75 Hz to 60 Hz. It looks great now.
