Cisco Codec C90 screen refresh/flicker

Hi guys,
We are currently experiencing issues where we have a Cisco Codec C90 with two outputs to two screens (HDMI1 & 2) Every now and then (randomly) we will see a quick horizontal flick run up the screen similar to a refresh…
This can some times happen on either screen. From the codec outputs they enter into an AMX switcher which then leads on to the displays etc… Now, it seams reseating the HDMI cables between the codec and AMX seems to resolve the issue for the interim until it returns later on.
I am trying to see in the logs of the codec if there is anything that matches the time that this occurs as we are in between if this is the codec or AMX controller that has the issue?
Below are the logs where I have seen the screen connected to HDMI#1 flicker within this minute; I have limited exp with codec fault finding so was wondering if someone can see something that sticks out to them?

Any help much appreciated!

From those messages it looks like the endpoint is seeing the external source disconnect and then reconnect (and then renegotiate the EDID info). So I'd been looking at your AMX switcher - have you got another one you can swap it with to see if the issue stays with this room, or follows the switcher? Or can you bypass it with a different cable or device?

Help!! Helix Screen Issue - Refresh/Flicker in Some Cases: Do You Have the Same Issue?!

I'm hoping somebody reads this and does the quick test below to help see if I found a Lenovo Helix display issue, or if just mine is defective!
I just received my Helix Core i7/8GB RAM/256GB SSD/4G LTE. (I have udpated all software, drivers, and Windows. Screen set at normal 32 bit color, 50/60 Hz refresh rates tested - default options unchanged.)
Under some circumstances, I can see some flickering on the screen, like on an old CRTs when you set the refresh rate to very low. I've done some tests, and here is one quick way to reproduce it....can someone else try it so I can see if my Helix is defective?
Keep your helix in normal portrait mode. Open the Windows sticky notes (the built-in app since Windows 7 that lets you put a "postit" on the desktop). Put that note in the upper right corner, so it takes like a quarter of the screen. Leave it on for 2-3 minutes at least (5 minutes best). Then swipe on the right side to bring the charms menu, click settings: now the larger blue vertical bar showing settings/shutdown button etc shows up. Right there, on the blue bar, where the sticky notes used to be underneath, mine flickers a LOT sometimes, and sometimes it's just a little. It goes away after a few minutes. It's exactly and only where the sticknotes were (the rest of my desktop pic is blue).
It's not a software bug. The issue persists on that spot of the screen if you immediately reboot, and progressively diminishes until some time has passed (~2 minutes). The issue also stays in the same physical location if you rotate the display to vertical. It's not a software issue with stiky notes, it's just the color; if I take a screenshot of the color and leave it at the same location on the screen dsktop, then bring blue like the settings bar, it does it. It seems that having yellow on the screen displayed for a few minutes, followed by blue, does it.
So this is visible easily if you have a desktop picture with blue on it (like ocean/beach).
On some occasions too, it just seems that changing completely colors make the overal screen refresh rate seem low; this is very subtle and lasts only for a few seconds. What I'm more worried about is the above test, the flickering is obvious to anyone looking at the screen.
Can somebody try? Again, the yellow of the sticky notes needs to stay on screen for a few minuets, then bring the blue bar of the settings menu on top, and see if you see the "flickering".
Thanks so much in advance!
Nicolas

Anyone? At least someone from Lenovo? I have a limited time to decide if I keep my Helix or not. If I get no reply I'll just have to return it...and I haven't found another alternative tablet that works for me (12" screen, Core i5/i7 and 4GLTE).
BTW, the issue I have isn't hard to see on my tablet. Just use the default windows sticky notes and bring the settings bar on top of it after a few minutes, and you'll see.
My guess is it could be related to the burn in issue posted on this forum. I only see the flickering if the image is left on for a couple of minutes then changed. Only a couple of minutes is needed, not long. BTW I showed it to several poeple, without saying anything, they all saw it immediately.
Not a driver issue. Tried latest drivers, no change. Also, tried an Asus tablet (Vivo Tab) for comparison, I don't see this issue at all, no problem.
Even weirder, it really seems to be specific colors doing that. Leave yellow on the screen and switch to blue. But not any yellow. like the sticky notes have a gradient in color, well only part of the color of the sticky notes make the screen flicker when blue is then displayed on top after that.

Turning off screen refresh

Hi,
We have a screen written in Forte UDS that highlights cells in different colours. Upon scrolling, these are updated to ensurevthe highlighting is correct. This does however cause a flicker on the screen as each cell is refreshed.
Is there a way of turning off automatic screen refresh, so we can do this, and then turn it back on again once we're finished ?

Black screen (or screen refresh) during the process of start up. T400, Vista home basic.

My 2 weeks old T400 Vista home basic can start up successfully. But every time when I start or restart it, during the start process, after inputting the password, there are 4 times of black screen (or screen refresh). Is it normal? Thanks.

Is there a way to speed up Premiere's screen refresh when editing?

Hello all!
I've been doing a lot of editing in the time-line. I'm editing two concurrent video tracks, and three concurrent audio tracks.
Whenever I split or delete portions of a clip, Premiere re-draws the tracks which takes several seconds (maybe 7 seconds or so?).
I know it doesn't seem to be a lot of time, but I am making many edits and it slows me down.
I know that if one "turns-off" the fancy graphics that display little video pictures and audio waveform displays that this screen refresh goes faster.
But is there some I should be setting to optimize my computer specific to screen refresh?
I believe I have mucho RAM, 500 gig of "extra" disk space, a fast dual core processor and am running Windows XP.
My project is located on a secondary drive.
Would a fancy video card help speed up the screen refresh?
Thanks!

Hunt,
(By the way, thanks to everyone for all the time that they're putting into this thread. I didn't think that it
would have evolved into such complexity ..)
My Windows Hardware Acceleration was set "all the way to the right".
I tried it "all the way to the left" and then, just one "notch" less than "all the way to the right".
(Hope that makes sense!)
It didn't fix the problem :-(
(Do I need to re-start Windows when I change this setting? I did not do that ..)
Here is some more information:
I think I had first noticed the video latency last August. I had attributed it to a lack of hard drive space and
installed a new internal hard drive (I have four 500G sata hard drives in my computer.)
Also, I had installed Premiere 7 on my computer about two weeks ago. (I have been using "3" to date.)
Both 3 and 7 act the same way, so I'm thinking that the issue probably isn't caused by a corrupt installation of Premiere.
I would suspect having both 3 and 7 installed concurrently as the culprit, but the issue existed long before installing 7.
If it were a system RAM failure, I'd suspect that I'd see a far more catastrophic failure?
And, when the video is playing "catch-up", I'm not seeing excessive drive activity, so I'm not sure
how big a role that the hard drove(s) are playing in this anomaly.
re: hard drives - the only set-up that I changed in the BIOS when installing hard drives was to turn on the
SATA interface for the drives .. maybe I've missed an optimization?
Maybe I need to go thru the "optimize your PC" list ..
Last thought for now: Is my Nividia GeForce video card adequate? I've got another video card that I can try.
Thanks copiously again!

How to change screen refresh rate in windows 7sp1 and windows 8.1 iso image using dism

sir when i install windows 7sp1 and windows 8.1 then after the completion of setup when first time windows boots up then task bar is not shown and display is not clear and when i check under monitor settings the screen refresh rate is 60 Hertz and when i
set the screen refresh rate from 60 Hertz to 75 Hertz, then everything is OK, plz tell me why this happens?
why windows 7 sp1 and windows 8.1 automatically sets the screen refresh rate to 60Hertz instead of 75Hertz.
how can i set screen refresh rate 75 Hertz permanently in iso image using DISM ?

That is not a function of DISM. Resolution and refresh rate capabilities can be determined by multiple causes. Drivers are one, another is that most modern displays will report their capabilities to Windows.
You can specify display settings with an answer file however:
<Display>
<HorizontalResolution>640</HorizontalResolution>
<VerticalResolution>480</VerticalResolution>
<ColorDepth>16</ColorDepth>
<RefreshRate>60</RefreshRate>
</Display>

Could be the graphics card, run the Apple Hardware Test
If the hardware test doesn't reveal any problems, use Lion Recovery.

Selection screen refresh

HI,
my question here is related to selection screen refresh.
in the program one parameter is defined like below.
PARAMETERS :P_EINT LIKE YFR1FIT_SALE_REF-POST_CODE DEFAULT 'EINT' OBLIGATORY VALUE CHECK.
In the table YFR1FIT_SALE_REF table the field POST_CODE the values were maintained at domain level. So, when i selected the F4 help on this field, all the domain values are appearing in the pop-up and also the validation of the data.
Now i have changed that, instead of domain, i have given the check table for this field. Though i did this change at table level, it looks these changes are not reflecting in the program. The program still showing the values maintained at the domain level, but not from the check table.
When i went to SE51 and given this program and 1000 as screen no, i noticed that the flow logic is not updated as per the latest changes. its still refering to the domain level values for validation..
So, to overcome this problem, it looks i have to update the flow logic of the screen 1000, which is created by default. Do you have any idea on how to correct this or refreshing the flow logic for the screen 1000.
Thanks for your time.
Regards,
Srikanth

As per [Input Help Hierarchy in the ABAP Dictionary|http://help.sap.com/saphelp_nw04/helpdata/en/9f/dbaa5435c111d1829f0000e829fbfe/content.htm] Check Table should have overridden the Domain Values in search help.
Please try to activate the screen 1000 (you can go through SE80) once again. Ihave faced such problem earlier.
But even if the problem persists check if you need to insert TABLES statement.. just dicing a though if it works.
You can paste the code also.

Screen refresh problem where data is entered and the screen doesn't refresh

Many people in the company are experiencing the odd screen refresh problem where data is entered and the screen doesn't refresh to show the updated result in corresponding cell formulas.
Microsoft have issued a hotfix to fix the issue for Excel 2003 as shown. Microsoft released a hotfix for this problem (<a href="advisory?ID=978908">KB978908</a>). Display memory tends to pick up data from hidden sheets and pastes it
into the active screen. No impact on the file. This occurs when protecting and unprotecting worksheets in VBA. I also suspect that enabling and disabling screen refresh contributes to this problem. In any case there is a fix, albeit with the following disclaimer:
As of yet I have not been able to find a fix for this for office 2010 and 2013, Any suggestions would be great.

Hi,
Based on your description, Excel does not show the text strings when you typing. It may be caused by the cell format, if we set the cell format as ";;;" in custom format, it will not display the text that you typed.
And the issue may be caused by the third-party input method, there are some compatibility issue between them.
If the issue still exits, please try the following methods
Verify/install the latest updates
Repair your Office program

Screen refresh problem in kde4 with konsole, nvidia and compiz

Hi,
I have for the last month or so been experiencing really slow screen refreshes in konsole. What happens is that the text often doesn't get refreshed and you end up with the cursor not on the correct line, blocks all over the konsole window and blank areas of text. Minimising and maximising the konsole windows seems to refresh them as does using compiz's scale plugin. As I spend pretty much all day using konsole this has been really annoying. I have today however found a fix in this bug report:- https://bugs.launchpad.net/ubuntu/+sour … mments=all
This was to go into ccsm, enable workaronds under utility and make sure "Force syncronization between X and GLX" is ticked.
Thought I'd share is this has really been doing my head in, so hope this helps someone else!

Screen refresh problem with Windows 7

Hello all,
I've recently begun testing Oracle with Windows 7 on a new HP 2540p notebook computer. I've encountered a very strange issue so far. After logging into Oracle, and Windows switches to Windows Basic theme, I should be taken to the main Navigator screen. But instead, the screen is simply white. If I drag (or nudge) the title bar just a bit, the screen refreshes and I can see the menu items. Then if I click on something (or even use hotkeys - ALT+F to get the file menu, for example), I don't see anything happen. But if I move the window just a bit, the screen refreshes and I can see that it did actually take my input, it just didn't re-draw the screen. I'm wondering if this may be a graphics driver issue (I do have the latest driver for the Intel Graphics Media Accelerator HD adapter), or if someone could point me toward a resolution to this problem. Any help is much appreciated.

Dear All,
Same problem of REFRESH PROBLEM also faced by but only a single and specific Windows 7 client.
if you have resolved the issue , so please share with us.
Thanks

Satellite M55-s3315: Screen refresh rate is 60 Hertz?!

I have bought Toshiba m55-s3315 analog m50-s.... with intel 910 built-in, shared dynamic 128 mb memory; screen - 14.0" WXGA widescreen display with Toshiba TruBrite . Only refresh rate i get is 60 Hertz. I have updated intel chip software and toshiba also ... I would like to know is it possible to get more than 60 Hertz. The only way is to get 85 Hertz is to add extarnal monitor. I there oportinity to get at least 75 Hertz screen refresh rate ??? It was possible with my old HP Pavilion ze 5000.
May be someone could explain me??
Thank in advance!!!

Hi
I have noticed that on some Toshiba notebooks the screen refresh rate is fixed on 60 Hz. I have two of them. On Tecra M1 is fixed and on Satellite 1900 not. I have tested it and there is no difference if the refresh rate is changed.
The TFT technology is much better than on usual monitors where the display flickering is visible on lower refresh rate. On display you will not see any flickering. In my opinion there is no reason for panic.
Enjoy the life!!!

Questions
1) Accelerated Graphics Port - there is enabled if yes that that it is necessary to make that it became accessible.
2) whether Frequency of hertz with 60 can be raised even up to 75.

Hi
I have noticed that on some Toshiba notebooks the screen refresh rate is fixed on 60 Hz.
The display refresh rate is not important on the notebook screens.
TFT matrix doesn't have such thing as refresh rate. It doesn't blink.
TFT like all other LCD screens doesn't have refresh rate parameter, only reaction time.
Your eyes are safe ;)
Ps: As far as I know the AGP port is not available.
