MBP/HDTV Resolution Mismatch

Hi all, long time lurker here.
I'm having a problem (obviously) getting my mbp (purchased june 2011) to connect to my shiny new insignia hdtv. i've got a thunderbolt to hdmi that's working swimmingly, i've been able to get the sound out of the external speakers. so far so good.
but. my mbp runs at 1680x1050, and my tv apparently doesnt, so when i mirror my displays i lose some off the top and bottom (the menu bar and an oomph off the top, about the same off the bottom) and i've got black bands on the left and right side of the tv display. how do i match my resolutions? i can't figure this out...

The manual may say that only lower resolutions are supported - but I am having great success with a different model.
My LC-37D90U (via DVI) connects at 1080p. (1920x1080p)
I have the 'View Mode' set to 'Dot by Dot.' At first I didn't - and I thought I was going to have to mess with one of the display config utilities. Have you tried configuring the digital input option for the DVI port? I had another Sharp which gave you the option to select the input signal. This helped out too. My old model was the LC-37D7U.
Hope this helps...

Laptop to HDTV / resolution problem

When I hook my laptop up to my hdtv and startx, X starts at a wrong resolution, how would I go about fixing this?

You could try out xrandr or lxrandr (a really nice frontend) to set the proper resolution.
A simple
xrandr --output LVDS --auto --output HDMI-0 --auto
worked for me. Get the right outputs by running xrandr without any parameters.

New MBP changes resolution when logging out

I have a brand new MacBook Pro 2.2 GHz Intel Quad Core i7 with a high resolution glossy display which have a native resolution of 1680x1050 pixles. But almost every time after I log out the resolution changes to 1440x852. In System Settings the resolution says 1680x1050 but under it it says (usable resolution 1440x852), and it's clearly the latter that is upscaled. Also it appears like I'm having two screens, which I'm not, and I can't change the brightness of the screen. On top of it all, the computer gets very slow.
The only thing that seems to get rid of this bug is by disable automatic graphics switching in Energy system preferenses, but I kind of want automatic switching...
Is this a bug that is going to be fixed soon, or will I have to have it repaired?

to test the issue try to install gfxcardstatus (so you can see which card you are using) and logout using intel card (close all app or open some like itunes, appstore...), the logout is ok.
now, to try using ati open app like cheese,firefox...
you can also switch card directly using gfxcardstatus .
i don't know if it is a bug for some new mbp or for all.

HDTV Resolution not supported, Desktop lost

I connected a HDTv to my G4. The image was great but circles were ellipses. I changed the resolution several times but one lost everything on the panel. It looks like a dark curtain. Changing the sets mode to a different input and then coming back shows part of the desktop. It is stretched and very low in resolution. The mouse and keyboard do not function.
The television has been tried on two computers, both with ATI cards. This sequence of steps reocurrs with both DVI and analog, VGA, ports and cables. The PRAM has been zapped with no result. Yasu has been run.
The old monitor still works fine when reconnected. The TV monitor works fine with the Tiger install disk.
Is there anyway to clear the computers memory and get this monitor working.

The settings associated with moniors can be found in preferences files (.plist) that also have the name "windowserver" in them. If you search on the term windowserver you should find at least two occurances. One will be com.apple.windowserver.plist and one will be com.apple.windowserver.xxxxxx.plist where the Xs will be some random string of characters and numbers. If you trash those files, it should be like starting over with the TV.

HDTV Resolution and WMV format

How do I export my HDTV Composition to a wmv format using presets. I tried to render with presets but I get a message "After Effects:AEGP Plugin Media IO Plugin:
MediaIO2 error: )x4
Not enough memory to complete this encoding." How do I fix this issue and render my project?

What exactly are your composition settings and what preset do you intend to use? This warning is usually coming up, if there is incorrect pixel aspect ratios and resolutions somewhere...

HDTV resolution question

Hi gang,
My HDTV can display 1080i and 720p. Technically speaking, should one be better than the other? I plan to do some head-to-head comparisons with various video and picture sources, but I was wondering if there was a well-established "preferred" mode.
Cheers!

Hey, Phil...
1080i has more lines for higher resolution and is interlaced... 720 less and progressive scan. Most don't have a choice. They usually have one or the other. If it were me, I would choose 1080i because there is more picture information. Then again, it also depends on the source format and the compression. If the data isn't there for 1080i then you will probably default over to 720.

HDTV resolution compatibality with MacBook

Hi,
I am trying to buy a HD Ready TV which also has a VGA input but wondering if i'll get my macbook resolution (1280 * 800) as the tv's is 1366 * 768.
actually hoping for higher resoultions when connected to the tv - atleast 1080i (otherwise whats the point in getting a big display)
can anyone give any idea on this? because most the the hd ready (720p) tv's come in that (1366 * 768) resolution... does it mean thats the max i can get plugging the macbook.
many thanks

Many HDTVs that have 1366 x 768 native resolution will accept 1080i input and process it and scale it down to 1366 x 768. That might work from a Mac but can be very dependent on the brand and model of TV.
There isn't really much point in running 1080i into a TV with that resolution. Most of the extra detail will be missing since the screen can't render it. Ideally you would want to run the TV at it's native resolution of 1366 x 768.

Random external monitor (HDTV) resolutions

Prior to the 10.5.6 update, I had no problems with connecting (VGA) my MacBook to my 27" HDTV at a resolution of 1366x768. No black bars, no distortion, no problems. To assist in my case, let's just say, I had wallpaper "A" for my MB screen and wallpaper "B" for the HDTV.
But ever since getting the update, I sometimes get another wallpaper background which we can call as "C". Another problem. The resolution changed from 1366v768 to 800x600. I couldn't find my default tv resolution anymore other than 1024x768 and a host of others. The closest one was 1280x768 which would leave black bars on the sides. The display prefs window calls it "Display" instead of the TV name.
However sometimes it works like how it used to and you can tell because:
1. The wallpaper is switched to "B" which was how I had originally set it up.
2. The resolution is 1360x768 and covers the full screen.
3. The display window in Sys Prefs shows it with the TV name instead of a generic "Display" tag.
Anyone out there who can help? Seems like Mac OS X uses some kind of a monitor profile but it's driving me nuts.
Thanks in advance for your comments and suggestions.

Forgot to add this but I also did a PRAM/NVRAM reset holding the CmdOpt+PR. Sound settings defaulted but no change in the TV resolution.
I tried a safemode login but still no luck with the HDTV.

Mavericks & MBP retina resolution change

Hello
I did a search before writing this, and since I found no posts, I am posting this.
I upgraded my 2012 retina MBP to Mavericks as soon as it came available.
No problems at all installing.
But I just noticed this:
on system information, I read under display:
Built-in Retina Display 3840 x 2400.
As long as I remember before the upgrade of OS X, I used to read 2880 x 1800...
(I set the display to "more space" under System preferences)
So, is it only me?
I went to check Apple's site of MBP retina (2013's) and it also reads : 2880 x 1800 native resolution...

Hello
I had a similar problem with Doom 3 and I've found a solution: it's due to the feature "Automatic graphics switching" being active. To prevent this from happening you need to disable it in System Preferences --> Energy Saver and uncheck this option. For further convenience you can install and use the application gfxCardStatus. Anyway, it's weird to have this happening in Doom 3 and have no issue for instance in Quake 4.
Hope I can helped.
Best regards,

Which HDTV resolution

Not sure where to post this one so I'm going to copy and paste and try a couple of forums and hopefully I can get a quick answer.
Thing is, I ordered a new TV today (arrives Saturday), a Pioneer 436SXE, but I'm now wondering whether to go back to the store and swap it for an LG 50PX4D.
Reason being that the resolution of the pioneer is 768 x 1024, which seems a bit strange since 720p HD TV is 720 x 1280. Now it may well be that the conversion is seamless but it seems a bit pointless to me.
So I'm all ready to go back to the store, after all the LG is 50" against the pioneers 43" and the res. is WXGA (1366x768).
The down side is that the LG is £ 200 more, doesn't have a digital sound processor (but I'm not a super quality audio guy anyway) and apparently blacks are blacker on the pioneer.
However, just as I've about decided on the LG, I consider the output of the mac mini I want to connect to it with a HDMI connector/switch. I assume the mini has a 768x1024 output, which ties up very well with the pioneers screen at 768x1024.
So now I am completely undecided, and if I'm going to change the order, I really need to do it tomorrow.
Questions I have are that I assume the pioneer will work well with the mac mini, but what about the LG. I'm sort of guessing that the TV will resize the output from the mac mini, but how will it look, will my picture get stretched or can I rely on the TV using different sized pixels and it simply being down to aspect ratio which I believe is 16:9 for both TV's. Or will the output from my mac mini simply use up 768x1024 pixels on the LG and leave the rest black.
Anyone with any input please provide it, as I say I need to decide soon.

Got the 50" Plasma and a 17"MBP, guess I'll just get the cable and see how it works, before committing to the mac mini.

MBP Bad Resolution - noticeable??

Hi, I'm thinking of getting a Macbook Pro 13", but I have heard that it has low resolution is it really noticeable???

Hi Jakob,
The MBP is 1280x800. That means, compared to a higher res display, the items displayed will be larger, but fewer will fit on the display (because they're larger).
The 13" MB Air has a higher res 1440x900 display. This will fit more items on the display, but they will be smaller. For some people (me), that is a deal breaker. I run my 15" 1440x900 at 1280x800 to get larger text.
If you're concerned about sharpness, I'd recommend going to a store with both the 13" MBA and MBP so you can compare them for yourself. I suspect you'll find the 13" MBP 1280x800 to be sharp enough. If res is a big deal to you, also consider the high res 15" or 17".

HT3131 MY macbook pro will only connect to my TV when the lid is open. When I close it to enter clamshell mode my TV gives me a error message saying "resolution mismatch." i have tried switching cables and using different TV's. it works on all my other TV

It works all my other TV's except my Magnavox 39 inch. i have made sure that the resolutions are compatible.

Yay! Solved my own question; just did a hard shutdown, worked like a charm! Funny, didn't before. But who am I to question salvation?

Screen Resolution mismatch. Can I force resolution prefs of remote machine?

Using Apple Remote Desktop, or Timbuktu, I'm connecting to a remote server that does not have a monitor attached.
Problem: I only have 2 screen resolutions available on the remote machine: 800 x 600 or 1024 x 768.
My local screen resolution is 2560 x 1600 (using a 30" Cinema Display).
Question: Can I change the display preferences of the remote machine to give me the same resolution as my local machine? (2560 x 1600)?

You are running the server in what's been referred to as 'headless' mode, meaning no monitor. Without a monitor installed the video card will default to one of three VESA compatible resolutions, 640X480, 800X600, or 1024X768; because it does not sense any EDID data on the display port.
You need one of these:
http://drbott.com/prod/db.lasso?code=0153-GHDD
which will allow you to set the display resolution on the remote 'headless' unit using the 'Displays' System Preferences panel. You don't even have to reboot the server to make it work, just attach the device and set the resolution to what you want to the limit of the video card's resolution. Settings will be preserved across reboots as the device present the correct EDID data to the video card even with no monitor attached.

[Solved]Catalyst 8.6 HDTV resolution incorrect HELP!!

After upgrade from Catalyst 8.02 (I know upgrade has long been in the queue for me), I cannot get my desktop resolution up to the 1360 (?) x 760 (?) (I forget the exact numbers but it was 13xx x xxx) My xorg.conf hasn't changed. I took a look at /etc/ati/ but I can't make sense of how it detects my TV.
If anybody has any suggestions please help!
*edit*
Just in case anybody else runs into this problem. I solved it by added Option "IgnoreEDID" "true" in the Screen section (xorg.conf).

From your Xorg.0.log:
(II) fglrx(0): DRIScreenInit done
(II) fglrx(0): Kernel Module Version Information:
(II) fglrx(0): Name: fglrx
(II) fglrx(0): Version: 8.49.7
(II) fglrx(0): Date: May 12 2008
(II) fglrx(0): Desc: ATI FireGL DRM kernel module
(WW) fglrx(0): Kernel Module version does *not* match driver.
(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work
You have to quit X, then rmmod and modprobe the kernel module - you're still using the old one. (a reboot would technically fix it too)
# rmmod fglrx
# modprobe fglrx
# dmesg | tail
The dmesg output should say you've successfully loaded the 8.501 driver.

Screen size and resolution mismatch after 2008-008 update.

This is very odd. My screen is shifting around every time I move the mouse on my macbook pro. It appears that the mac doesn't think the full resolution will fit on the screen, and so shifts a few pixels up (or down, left, right) whenever I move around the screen. It's very difficult to use since it distorts whatever I'm reading. I've tried selecting different display resolutions: 1440x900, 1280x800, & 1024x768, but the problem persists even on lower resolutions.
Could be a red herring, but I've checked the install.log for errors and found a couple instances of this sequence:
Dec 22 07:42:04 gseven : update_prebinding[25268]: update_prebinding: too many errors (101)
Dec 22 07:42:04 gseven : update_prebinding[25268]: update_prebinding: error: terminating
Dec 22 07:42:04 gseven : update_prebinding[25268]: update_prebinding: error 256 running updateprebindingcore
I don't know if that could even be related. Anyway, does anyone have an idea how to fix this?

Hi xerhino, and a warm welcome to the forums!
Good work on your part!
Hope your doing OK with the Snow, Ice, and Winds!
