Hello fellas,

So I plugged-in my MacBook Pro (from DVI) into my Westinghouse 32" 720p LCD TV (into HDMI) which has a native resolution of 1366 x 768.

Specs here.

I am having troubles getting a sharp image on the TV.

When I open-up System Preferences > Display I get a window on my MBP and one on the TV. 1366 x 768 isn't listed in the available resolutions. Some of the ones listed show "Interlaced" between parenthesis. If I click on the highest resolution setting available 1920 x 1080, the image flickers a bit and it is visible.

Anyone knows how to set this up properly?
 
I used DVI-HDMI with my Mac Mini on my 26" HDTV, it can't output that resolution so you'll have a little blank space either side of the screen. Adjusting the frequency settings in System Preferences > can help with the sharpness...

Wouldn't advise using a resolution higher than the TV is meant for. That's why I want to get my hands on the Sharp 32" 1080p unit

Far as I can tell, you need to use a VGA connection for the full 1366x768.
 
The television should have something along the lines of 'View Mode' to fit the output to the TV. I use Dot-to-Dot on my Sharp Aquos for best results!
 
Thank you guys.

Here is screen shot of what I see on the TV.

How can higher resolutions than the TV native be available in System Preferences > Displays?

What does the "Interlaced" mean?

I don't have a VGA cable. I will procure one this week and try DVI-VGA (I have a VGA port on the TV) as opposed to DVI-HDMI.

Just guessing, but your Mac can probably tell that the HDMI connection can output 1080

Yes, perhaps.


Just pick the 720p setting and be done with it... what's the big deal?

Which resolution is the 720p setting?



Check under "Options". There may be a "Best for Video" option. Try un-checking it, if on.


It isn't checked and it's grayed-out.

I am attaching a screenshot.

I don't believe you can get 720p over hdmi, you'll probably have to use a vga cable.

Understood. Didn't know that.

I thought that by going the DVI-HDMI route, I'd get a better picture quality. So in fact, for a 720p LCD TV, is there any advantage to using HDMI over VGA when both port are available on the LCD TV, or does it depend on the particular TV model/ brand?

Looks that way doesn't it?

I have a similar TV but didn't have a DVI-HDMI connector so used the DVI-VGA adapter that came with my MBP. It immediately recognised the native resolution of the TV and used it. I had to do the auto adjust on the TV itself to get the sync right but after that the picture was excellent.

Sometimes the simplest solution is the best :rolleyes:

HDMI does 720p. The problem is that it only does 720p (ignoring 1080i/p for the moment).

720p = 1280x720 but the screen has a resolution of screen is 1366x768 so you get a black border on the screen if you use 1:1.

VGA solves this issue by allowing you do the native res.

However some TV's have a fully DVI compatible HDMI port (samsung R8 series) which allows you to use the native res over one of the hdmi ports.

There aren't many of these screens though!

Very insightful thank you.

Currently trying to find a VGA-VGA cable to use with my DVI-VGA adaptor & the MBP and the TV.
 
I have a SOny Bravia KDL 32D3000. Because I don't want those borders, I'll go for a mini-DVI to VGA connector on my MacBook. Here is the back of my TV. If I use the VGA port, does that mean I can't connect a jack-to-RCA cable ?

I just installed my Bravia KDL-32D3000 in the living room :p The HDTV is absolutely awesome, but I have some problems using it with my MacBook. I used a mini-DVI to VGA adaptater, a VGA cable, and a jack/jack 3,5 cord for the sound.

However, the TV is not detected by the MacBook. I still get video output, but it doesn't recognize the TV and doesn't offer me the 1360x768 resolution. At max, I get a 1280x768 res. This is also not working over 60hz, otherwise I get a 'signal unknown' on the TV.

Damn, I really should have gone the hdmi road for the video, I thought I wouldn't get any hassle using a VGA connection, but it looks like I'll have to use SwithRes or a software like that, even with VGA.

- what should I do about the resolution ?
- what frequency should I use ?

Thanks, I really need help :)


Edit:

Here are the screen specifications with the VGA input :
- 640 x 480 à 60 Hz
- 800 x 600 à 60 Hz
- 1024 x 768 à 60 Hz
- 1280 x 768 à 60 Hz
- 1360 x 768 à 60 Hz

This is the last one that I can't choose on my MacBook. Any help ?

Make sure your Macbook is running in extended desktop mode and not mirrored mode. When you connect it to the TV via the PC Input(VGA), it should auto-detect the correct resolution.

When I connect my BRAVIA to my MBP, I just plug it in and it autodetects everything.
 
I'm indeed using the extended desktop. It works fine, except that it doesn't detect the screen and the 1360x768 resolution :(

Is there a driver to install or something to do on the MB, so that it could detect the Bravia like the MBP does ?

See if there are any settings you can change to affect the VGA input on the TV set.


Since I started this thread, I bought a DVI to HDMI cable a VGA to VGA (which I use with the Apple DVI to VGA adaptor) and after trying both, the effortless and best image is obtained using the VGA input of the TV.

It works very well on my TV: I just plug the cable into the DVI port. My TV auto-detects the source and turns itself on and my MBP detects the TV and sets the reolsution and color profile. Love it when it "just works".

Now for the sound-out from the MBP I wanted to use the Airfoil app for there is a delay in transmitting to the Aiport Express which makes the app useless when used to watch movies (image-sound out of sync) while the MBP is plugged into the TV. So I just the headset jack on the MBP to get sound out.
 
I have a mbp and have the same problem when I hook it up o my 32" JVC. It's a bitch to get working and when I finally do it's very distorted and an overall nasty image. I haven't gotten it to work with other tvs yet, so instead of buying my next tv. I'm going to buy an apple 30" display for my mbp, ps3, :apple:tv, and eyetv (through my mac pro which I'm getting soon).

I would love a 30" ACD but I cannot justify the cost. It's still too expensive compared to the alternatives out there. But if I were to buy a 30" computer monitor, I would also get the Apple Cinema.
 
grayed out 'best for video'

Yes, perhaps.




Which resolution is the 720p setting?






It isn't checked and it's grayed-out.

I am attaching a screenshot.

Does anybody know why the 'best for video' option is grayed-out and how to resolve this problem? I'm having the same issues and nobody really answered RichardF (I'm not trying to hijack your thread)
