Twist s230u second display bad resolution

Hi I just bought a ThinkPad Twist S230U (3347-6LU) with Intyel HD 4000 graphics adapter and I try to connect my external 22" LCD monitor (1680x1050) using the miniHDMI to HDMI cable, but when I extend the desktop to the second display only have the 1920x1080,1280x720 and 1024x768 choices.
How can i add the correct resolution (1680x1050)?
Regards,
Alejandro Castrejon

I'm having a similar problem. When I plug the HDMI cable into the laptop, the screen does a quick flash to black like normal, but there's no signal to the external monitor. After a few seconds, the monitor goes into "HDMI power saving mode." I've tried multiple cables, multiple adapters, and even tried hooking it up to an HDMI projection system at my office. Same result with everything--laptop acts like an external display has been connected, but there' s no picture at the destination.
This used to work without a problem, so I don't know what's changed. I tried updating the display driver and even went back to Windows 8 and up to 8.1 again. Nothing. It's a huge problem because I travel and present for a living and some of the venues only have HDMI. I bought a minidisplay to HDMI adapter, but it would be nice to use the native port.

Resolution Limitations with Second Display

What´s the maximum video resolution macbook MB403 can drive?
I´m using a second display (Samsung wide screen syncMaster 226BW, and after configuring it at 1680x1050 - which is the usual resolution for this type of display, I realized that the actual resolution was not greater of 1280x800, although the video configuration set indicated and normaly accepted the 1680x1050 as the second display resolution.
Is there a configuration setting I have forgotten?
It seems that 1280x800 is the higher resolution accepted by macbook own display. Is there any relation or limitation related with a second display?
Thanks.

So does anyone have experience with the Envision 22" LCD display (G2219w1)?
It works well with my 5-year-old PowerMac G4 BUT with the MacBook the whites and grays are tinged with color and the overall colors are overly saturated. Moreover, the pictures are grainy and text is muddy. I can't seem to find a good match of resolution after trying several combinations. It's reasonably sharp at 1680x1050 but the image is quite small (about 3" border on all sides which is pretty much the same size as the MacBook).
Is there anything I can do? I've tried lots of adjustments on the LCD and in the display configuration on the MacBook.

Png file displayed on web has very bad resolution

But on my Mac it is sharp. It was a pdf in Acrobat "Saved as..." a png. Very frustrating problem begs for solution. Thanks in advance.

You've identified that Acrobat's export of the image to PNG was spot on ("... on my Mac it is sharp.").
Some possible sources of the web based image being of "bad resolution" present themselves.
--| Some web based image hosting services provide uploaders that actually downsample an image.
This is to reduce the image file's size and results in destructive remove of pixels. File size is smaller and resoultion can/does take a hit.
--| There may be an issue related to the brower used. You could always install and try out other browsers to check this.
--| You local machine may have a failing graphics card.
There may be other issues. A web search might turn up some leads.
Regardless, neither Acrobat nor Adobe Reader are web browsers and neither are "image viewers" for image file formats such as PNG.
Be well...

Thinkpad Twist s230U no internal display, works on HDMI and mini display port

Hi,
My Thinkpad Twist does not display anything when turned on except on external monitors. The Device manager shows a greyed out internal display icon, says it is not connected.
1. Could this be the power connect ribbon cable p/n DC002C003W00 have a fractured wire(s)? I have tested for open circuit between PWR1 and PWR2 connectors and there are 4 sequential pins which are open circuit. Is this normal?
2. The touch screen works
3. There appears to be absolutely no LED backlighting working
4. Is there a possible fix for this and if so is it the power cables or some physical problem with the ribbon cables OR is it definitely a new display that is needed using existing cables?
Thanks in advance
Andrew

The last 4 pins on the connector are unused I have determined so it is not the power ribbon cable connector.
I found two wires fractured in the LCD ribbon cable right at the point where it feeds through the twist mount. I expect this could be a common problem after use. After repairing these two wires it did not fix the screen problem. I have ordered a replacement LDVS ribbon cable and will report back once I have replaced that.

Cannot Disable Auto-Rotate on Twist s230u

I want to completely disable the screen auto-rotation on my Twist s230u and prevent it from re-enabling at all. The only modes I use it in are tablet mode or laptop mode, so I have no use for this. Is there a way to do this?
The checkbox under the Screen Resolution section of Display Properties doesn't seem to do jack. The screen still rotates when this is unchecked. I've also rolled back the driver of the Lenovo PM Device from 1.67 to 1.66 as per this thread. Can't say I've noticed a difference after this either.
Any other ideas? Thanks.

Dear Redv
Welcome in lenovo forums
All what you need to Disable the auto Rotate Screen is to press on the highlighted button as shows below :-

Messed up color display and resolution because of mini-DVI to video adapter

Once I connected the mini-DVI to video adapter to the tv and got weird colors on my screen for a while but then it worked out, then after a while I disconnected the cable and turned my computer off. After that, everytime I turned my macbook on, the color is fine for two seconds and then it turns into a weird offset color, really bright colors, kinda sketchy and just a few colors, and a weird resolution and display obviously, but then I just connect my Mini-DVI to video adapter and disconnect it again (quickly) and the color returns to normal. How can I make the normal colors stay and not have to connect the mini-DVI to video adapater everytime I want to see the normal color display and resolution??
please help!

Open the Universal Access pane of System Preferences, click on Seeing, turn off the White on Black, VoiceOver, and Zoom options, and drag the Contrast slider all the way to the left. If the issue persists, create a new folder on the desktop, drag half of the items from the Library/Preferences/ folder of the item in the Finder's sidebar with the house icon into it, and narrow down the files until you've isolated the one responsible.

Can you help me fix my screen? It randomly has a bluish tint, bad resolution and horizontal flashing lines

Hi all,
It's a 15" 2.4 Ghz Intel Core 2 Duo MBP running on Leopard 10.5.8, bought spring 2008.
About a couple of weeks ago, my screen started randomly switching to a strange blue / purple tint along with a bad resolution (can't really read text on screen) and flashing horizontal lines in the background. It started worrying me given I'm working with it all the time and am hoping for this machine to hold on for a few more months until I can buy a new one.
It would happen randomly for a few minutes at a time and then revert back to normal screen.
I found a lot of references to a similar problem in a few threads such as this one:
https://discussions.apple.com/thread/1456983?tstart=0
My screen has gone strange again now and isn't reverting back to normal so far even after I tried restarting it. It was normal for 2 min only ans then back to bluish. I tried all the display fixes indicated in the threads but none of them work and I'm not exactly sure my issue is the same given I can still see the tint and horizontal lines in particular if the screen saver goes on, and the resolution on screenshots I've seen of other people having blue tint screen issues seems to be normal (as in text is legible).
Any ideas on how to fix it? Do you think it might be more of a software or hardware problem..? Would it help if I try upgrading my Mac OS?
Thank you very much for your time

Thanks a lot for the reply, I was worried would say that outright. Screen just only reverted back to normal after a couple of hours. As you said probably best to bring it in for diagnosis, I'll try to do that asap though of course I'm nowhere neaar any AASP at the moment.

Using second display via eMac's mini-DVI to VGA adaptor

Hi,
I've got a 19inch widescreen display from Acer, model no. AL1916W. I have apple's mini-DVI to VGA adaptor and have connected the second display to the point where it mirrors the screen on my eMac, however I don't want it to do this.
What I had intended is that the second display would act as an extension of my eMacs screen, so I can drag windows across for extra space. Is this possible with the eMac?
Put more specifically, I want to be able to put logic's main (arrange) window on the Acer widescreen, and then have whatever else on the eMacs screen? Is there a workaround to do this?
help much appreciated,
Toby

Hi,
It's funny you should send me that link, I actually found that a couple of hours after posting this and tried it. It worked perfectly, I now have the widescreen running in it's native resolution and working as a separate screen which I can drag stuff in and out of. I came back on here to mark the question as 'answered' but I couldn't find how.
thanks for your help,
Toby

Setting Up Second Display - ADC to DVi - DVI to HDMi to Widescreen TV

Trying to set up the widescreen TV as a second monitor for visitors.

My video card has a VGA and an ADc connector. Connected my 19" monitor using VGA connector.
Got a Belkin ADC to DVI adaptor for the ADC output.
Got a DVI to HDMI cable to connect to the TV.
Everything plugged together Ok.
On powering up the Mac, the Widescreen TV shows the grey screen with the apple symbol and the spinning wheel, this disappears and the 19" monitor comes on. This displays the desktop picture, but no icons appear and that's all that happens. Power off theMac, power off the Widescreen TV, power on the Mac and it comes up normally. The grey bootup screen appears on the 19".
So how do I get the system to recognise BOTH displays. I've played with the System Preferences, but because the system won't recognise both screens I can't switch on the mirror option.
Any thoughts on the problem welcome.
Ta.

From this information from my system profile:

I take it that OS10.5.5 is detecting my Viewsonic VA1912w Screen connected to the VGA; but for some reason has decided that there is NO display (my HDTV via HDMI) connected to the ADC.
I've been playing with this for a day or two now. With both screens attached and powered on I power on the G4. The grey "boot up" screen with the Apple logo and spinning wheel appears on the HDTV screen, meaning the Mac has found it and is using it. While this is happening the Viewsonic is grey.
Then both screen go black, the Viewsonic goes blue, then puts up an old desktop picture, while the HDTV remains black. And that's all that happens.
I have to disconnect the HDMI cable from the HDTV, power down the HDTV & the Mac, then power on the Mac again to get it back.
So why would the Mac detect the HDTV, then decide it's not there?
I've tried adjusting the display settings and frequencies to no avail.
Anyone?

x x x x x x x x x x X X
...with 10 rows of 3 as opposed to 8.
I have had trouble finding an adapter to use to convert this to VGA (which is what I meed to connect my second monitor). I've searched the Apple Store online to no avail, as well as Google. Perhaps I've had no luck because I don't know the name of this part.
Any help is much appreciated!

Hello! Does the port look like the one below? If so you'll need an adapter. Tom
Actually, HERE is the page i was looking for that shows and describes all dvi connections.

Using a second display

I just purchased a 15" Powerbook and have attached a 23" Cinema Display. I have several questions:
Is it possible to turn off the second display without physically detaching it from the PB?
Is it possible to turn off the PB screen and just use the second display? (I know about getting a second keyboard and keeping the PB closed.)
When I have the two displays in "mirror" mode, I am not getting a full screen on the second display when i use the highest resolution on the second display. Is there a way to correct this and still maintain the highest resolution on the second display?
Thank you very much.

Hi cerett --
I have to preface my responses by saying I don't have a second display attached to my PowerBook. That said, I think I can answer the first two of your three questions. Here goes:
• Is it possible to turn off the second display without physically detaching it from the PB?
I think your 23" ACD has a power button, right? If so, why can't you just power down the ACD if you want to turn it off without physically detaching it from the PB.
Alternatively, and this also goes to my answer to your second question, you could turn down the brightness to the point where the screen is totally dark. Now, this doesn't seem like an ideal solution by any means, because you'd still have power running to the ACD for no reason, but it would seem to accomplish what you want anyway.
• Is it possible to turn off the PB screen and just use the second display? (I know about getting a second keyboard and keeping the PB closed.)
You write that you already know how to use your PowerBook with the display closed. See: http://docs.info.apple.com/article.html?artnum=86286 So, it sounds like you would like to leave your PB open, but just not have the display on. If so, it seems to me you could just decrease the brightness (using the F1 key or, of course, System Preferences > Displays > Display) to the maximum extent possible so that they display goes totally dark. May not be an ideal option (see above analysis), but it would seem that it should work for you.
Sorry, but I can't help with your third question. I'm not sure, but you might increase your chances of getting the information you need, if you reposted that third question in the Apple Cinema Displays forum, here -- http://discussions.apple.com/forum.jspa?forumID=981 -- as the answer to this question may have more to do with the characteristics of the ACD than of the PB. I'd wait to see if someone comes along here first, and, if not, then repost there.
Good luck.

My Mac Pro Desk Top computer no longer can "see" my second display??

I've tried reversing the connections on the back of the MacPro but it still doesn't "see" the second display. I've had these two displays hooked up for years with no problems. I recently upgraded to Mountain Lion and I just had the MacPro in the Apple Store for a "One To One" transfer of data to my new MacBook Pro laptop. When I brought it back home it still worked fine. I then was cleaning up some stuff and I know I went into my "Users and Groups" panel in System Preferences and I did remove some items from the "Login Items" list that open automatically so maybe that is the problem?? I know the second display is getting power and recognizes it's connection to the compuiter because when I disconnect it, it says, "no signal" and when I reconnect it, it just goes to sleep. Advice appreciated.

Some of the graphics cards that had two DVI connectors had one Dual-Link (suitable for all resolutions including wider than 1920 wide) and one Single-Link (suitable for resolutions up to 1920, but not wider). This does not appear to be your problem, since both are less than 1920 wide.
The "Drivers" business is a complete Red Herring (Not Applicable), as the Mac does not use Drivers for displays -- it uses a unified driver for the Display CARD, and customizes it based on the capabilities reported by the Display when connected. In order to get this to work, the display must correctly self-identify.
To verify that the display is correctly detected, look in:
About This Mac > ( More Info ) > Graphics and Displays ...
... a correctly self-identified display shows its Name and its maximum resolution. be skeptical, this information does not update when you plug/unplug the display, and you have to close and re-open this window (or possibly the entire program) to get the information to refresh after a change.
If either display provides a USB cord, it must be plugged in to complete the display connection and provide display ID and control (this is much more common with Apple displays that third-party displays).
Is there any evidence of trauma to the display connectors or cables? Any bent pins on the connectors?

Driver for a second display

I have an AOC brand monitor and the proper DVI connections to add it as a second display, however it doesn't work as plug and play and the AOC website only has windows drivers and says to contact Apple tech support for an appropriate plug and play driver. Where can I find a driver for this?

You should not need any drivers, unless it is some specialized monitor that does more than a normal DVI display (such as touch screen or 3D).
What is the native resolution? An iMac can go up to 1920x1200 pixels for an external display that is DVI (which is a typical 23" or 24" widescreen display). Larger displays (higher resolution) will not work.

When I connect a second display both displays start to cycle on and off.

I am connecting a second display that works on both my macbook and macbook pro. When I connect it to my imac, both monitors start blinking on and off.
Any ideas?
Thanks

Long story short I solved the problem, and it was totally a model issue. It is the HP w2207, which apparently has a problem with iMac 24 inch, the nvidia graphics card, mini DVi to DVI and 10.4 in particular. You see these two devices, just don't get along very well. The imac tries to auto set the monitor at one resolutions and the monitor tries to auto set itself at another, and they will continue to do this indefinitely. However both when I switched to a VGA cable, which I believe prevents the monitor from auto setting itself, and when I upgraded to 10.5 solved the problem.
Personally I didn't mind the upgrade, as I was planning to do it anyway, and is definitely the better solution as there is noticeable difference in the color between the two cables.
Anyway thanks for the help everyone.
