I have a Samsung LA40M81BD HDTV and I tried connecting my HP Pavilion laptop to it via VGA but the HDTV does not seem to detect any signal from the laptop.

I think the laptop knows there is an external monitor connected to it because when I open up the Intel Graphics display, I can see the option to choose either the laptop or monitor as my display. I have selected *all* the display resolutions for the external monitor and nothing appears on the HDTV. I tried using Powerstrip but nothing changed.

I reported the problem to Samsung. They sent a technician who then replaced a board in the HDTV but it still doesn't work. I just want to get something displayed on the HDTV - even if it means at 800x600 with overscan problems and the lot!

Can any guru on this forum help? I can't think of any other solution. Thanks!

Change the "TotalDTDCount to say "1" then add the new DTD to HKR,, DTD_1 (remembering to add the 37,01 to the end). Re-install the drivers and you should be good to go.

You just need a suitable DTD. If you can get your Dad to send you the Intel Diagnostic Report when we could have a go at creating one that might work.

V End of Blanking Interval = Vsize + V_Front + V_sync + V_back

Hello archibael,

Thanks so much. I've been using DTDcalc 1.02 to create the 1080p48 an 1080p50 (with reduced front H porch) custom resolution with success within Vista.

I now have the two customs resolutions within Intel Graphic configuration panel and can successfully select 1080p48 mode for the desktop (54KHz/48Hz). I can play HD-DVD and BRD on my Sony G90 with no judder and sharp picture.

All is working very nice except one single thing : each time I boot the HTPC, Vista is telling me that "the Display driver was not responding but has been recovered correctly" and swap back the desktop to 1080p60 mode (I need to re-select the 1080p48 mode from the Intel control panel, each time I boot up the HTPC...)

Intel DD is 15.8.2
Vista Ultimate SP1
My HDMI switcher : Yamaha DSP-Z11 A/V amplifier with passthrough mode activated.
My display : G90 with moome IFB-HD HDMI input board (max monitor supported mode = 1080p60)

Any idea why the 1080p48 mode cannot be keeped by Vista at boot ?

Thx.

John

P.S. I get 7.1 PCM on HDMI from PowerDVD 7.3 HD player through P5E-VM HDMI M/B on my AV amplifier !

Hi John,

Sorry it's me responding but Archi doesn't seem to have been around much for the last week or so (work commitments I would think).

Do you have UAC enabled? If so try launching something that creates a UAC prompt and see if you get the same "Driver Not Responding" message.

I know it seems like a strange question but there are issues with certain parameters in custom timings that can cause the sort of behaviour you're seeing. The one I seem to remember most (although I don't have my documentation to hand) is if you have an odd number value for "H Start of Sync Pulse".

Hope this helps. If not Archi should be along soon I hope.

Hi vl99,

There seem to have been a few reports of this nature (laptops and Samsung TV's) over the past few weeks. I'm sorry to say I haven't been able to help at all

I bet if you were to connect a standard VGA monitor it would work first time. When you selct the TV from the Graphics Tray are you configuring it as a single display, clone or extended desktop?

Try booting windows into "Safe mode" with the TV connected and then restart. I had an issue last week with a G35 system not syncing with a Panasonic Plasma and booting into safe mode then restarting seemed to force something (not sure what) and it worked on the next reboot (not very scientific but...).

Also, if the Laptop is "seeing" the TV you should be able to get an Intel Diagnostic Report which contains the EDID information for both displays. Create the report and post it. It may not help but we can try comparing it to the other examples I've seen (and it will tell us what driver version you are running).

One final thought, are you running Vista? If so try disabling Transient Multimon Manager (TMM).

To disable TMM do the following;-

Press the Windows Key and type "Task Scheduler"
Navigate to Microsoft\\Windows\\MobilePC
Right Click on TMM
Select Disable
Reboot

I admit this is a stab in the dark but it's worth a shot.

Yes, UAC still activated on my unit (what a boring stuff ). To let DTDCalc been able to write the registry, I've been forced to run it with full administrator privileges by changing the DTDCalc.exe properties... How to create an UAC prompt ? Sorry but I'm a newbee on Vista

Here is the parameters I've stored for the 1080p48 mode :

Pixel Clock = 118.681MHz
H Active Pixels = 1920
H Start of Sync Pulse = Hsize + H_Front = 2008
H End of Sync Pulse = Hsize + H_Front + H_sync = 2052
H End of Blanking Interval = Hsize + H_Front + H_sync + H_back = 2200

V Active Lines = 1080
V Start of Sync Pulse = Vsize + V_Front = 1084
V End of Sync Pulse = Vsize + V_Front + V_sync = 1089
V End of Blanking Interval = Vsize + V_Front + V_sync + V_back = 1125

You may be right : my "V_Sync" value is 5 : odd number... Maybe I should try "6" value . Not sure if I update the 1080p48 mode with this new "V_Sync" value, I can replace it with DTDCalc in the registry ...

I'll let you know

Hi Stu,

Rather than runnning the risk of trying to create a DTD from scratch, I did a bit of digging and found an old post from Archibael on the Intel Software Community forum where he was helping someone else with a 6710b laptop.

The resolution they were working on was 1280x800 which is 16:10 so hopefully this will be OK for your Dad.

The DTD is 9A 20 00 90 51 20 1C 30 40 88 13 00 00 00 00 00 00 1C

Put this DTD in place of the current values under DTD_1 in the ini. Don't forget to comma separate and add 37,01 to the end

Archibael also points out that this resolution may not be allowed by the video bios so just in case also add

9A 20 F8 98 41 20 1C 30 40 88 13 00 00 00 00 00 00 1C to DTD_2. This is 1272x800.

Change the TotalDTDCount to "2" so that both options will be available when you reinstall the drivers.

Good luck.

Hmmm. This may not be it then. I don't think the "V_Sync" value caused the problem. Sorry

To get a UAC prompt just try opening Device Manager.

Sorry, yes, work presses, and also I spent the weekend hiking the Grand Canyon (highly recommended!). Is it possible the Persistence trick would kill this reboot issue?

OK Wo0zy, I will also try to disable UAC prompt/pop-up to see if this will solve the problem...

Hi archibael,
I have a Toshiba Satellite Pro U300-116 notebook with Intel GM965/X3100 graphic adaptor, which I connect to a Sony VPL-AW15 projector trough VGA-out.
The native resolution of the projector is 1280x720. Although I have installed the latest video drivers from Intel and the latest bios from Toshiba’s site I cannot obtain the specific resolution.
I have also used DTDcalc 1.02 to create custom resolutions but it seems that the specific resolution is blocked from the BIOS.
I have to note that I succesfuly obtained 1280x718.

According to the sony manual the optimum signal from the PC would be:
1280x720
fh=44.772 KHz
fV=59.855 Hz
Sync= H-neg, V-pos
HSize = 1664
Can you please recommend the optimum DTD parameters to use?

Thanks in advance.

Hi John,

Don't disable UAC, I just wanted to know if the UAC prompt also causes the "Driver not responding" error.

The Persistence trick is only valid for drivers older than 15.8.2 I believe.

If you are running such a driver, DPlettner found a fix (see http://www.avsforum.com/avs-vb/showt...938473&page=35 post #1037).

Not much you can do to get around a BIOS block (except hack the Modes Removal Table in the BIOS... which I would probably chance but which I don't advocate for the amateur).

I would personally go back to the 1280x718 DTD that worked for you and modify it to be 1278x720 instead. In my experience lines of resolution seem to have a greater chance of triggering random errors than horizontal number of pixels. But if it's working for you and you're happy with it stay with 1280x718.

Please help! My HL-S5087W will not accept a 1080p signal over HDMI from my HTPC.

I am using the onboard graphics of my Asus P5E-VM HDMI using driver version 6.14.10.4935 for Windows XP Home. My TV reports the following EDID:

Unless I'm mistaken, the DTD "02 3a 80 18 71 38 2d 40 58 2c 45 00 09 d5 52 00 00 1e" is the standard timing for 1080p60.

I have used DTD Calculator to set up this resolution according to the instructions. When I try to switch to it I get about 4 seconds of brilliant picture before the TV insists that it does not support the signal that is being delivered. The TV is able to display another 1080p60 source and I am able to view the signal from the computer on another 1080p monitor without issue.

I have tried so many different configurations that I'm convinced that the TV is not behaving correctly, but I'm hoping that I'm just doing something stupid because that is much easier to fix.

Please, what am I doing wrong? Thanks in advance.

You're doing the right thing, but it seems like the TV isn't syncing well to the signal. Perhaps the TV is finicky about the exact pixel clocking; the DTD you specified is certainly the right one-- not only is it the standard for 1080p, but your TV is expressly asking for it. Try a slight tweak up or down on the pixel clock (modify the initial byte up or down a bit from 02 to 01 or 03).

It is calling out 1080i as the "native" resolution of that TV, so perhaps that would work better.

Wo0zy,

I've tried connecting the HDTV as single display, clone and extended desktop. None works.

On your suggestion, I tried booting the laptop in safe mode with the HDTV connected and then rebooted the laptop in normal mode. Still didn't work.

Will try to get the EDID information for the HDTV but if I'm not mistaken (I've searched for it before), I couldn't find it like I easily could with the laptop's screen. I'm running Windows XP Home, by the way.

I'll probably need to look for a PC/laptop not using Intel Graphics card and test it out. I'm beginning to see the light fading fast at the end of the tunnel ...

I bet if you were to connect a standard VGA monitor it would work first time. When you selct the TV from the Graphics Tray are you configuring it as a single display, clone or extended desktop?

Try booting windows into "Safe mode" with the TV connected and then restart. I had an issue last week with a G35 system not syncing with a Panasonic Plasma and booting into safe mode then restarting seemed to force something (not sure what) and it worked on the next reboot (not very scientific but...).

Also, if the Laptop is "seeing" the TV you should be able to get an Intel Diagnostic Report which contains the EDID information for both displays. Create the report and post it. It may not help but we can try comparing it to the other examples I've seen (and it will tell us what driver version you are running).

One final thought, are you running Vista? If so try disabling Transient Multimon Manager (TMM).

To disable TMM do the following;-

Press the Windows Key and type "Task Scheduler"
Navigate to Microsoft\\Windows\\MobilePC
Right Click on TMM
Select Disable
Reboot

I admit this is a stab in the dark but it's worth a shot.

I would personally go back to the 1280x718 DTD that worked for you and modify it to be 1278x720 instead. In my experience lines of resolution seem to have a greater chance of triggering random errors than horizontal number of pixels. But if it's working for you and you're happy with it stay with 1280x718.

Thanks for the immediate response Archibael!

I have used the 1280x718 resolution but I don't know what exactly DTD I have to insert to DTDCalculator in order to match the specific fH, fV, Hsize etc parameters.

Can you please suggest specific DTD values to use?

Thanks again!

Really sorry to hear that

If the TV is connected and recognised (even if there is no picture) the Intel Diagnostic report should give you the EDID for both displays (don't forget to save the report as the EDID isn't included until you do).

Another spurious question Are you overclocking your system at all?

This is the other scenario that caused the "Driver" errors for me. Even ensuring that my RAM frequency was "fixed" didn't help.

I'm rubbish at OCing but in this case the system was rock solid until I did anything which "stressed" the graphics. Just a thought.

Thanks for the quick reply archibael. I will try tweaking the pixel clock and see if that gets me anywhere.

I did notice that it is calling out 1080i as the native resolution and it does accept a 1080i signal, but it nearly gives me a seizure every time I try to drag anything. I don't understand why a set that accepts 1080p would say that 1080i is the "native" resolution unless it is down converting. If this is the case Samsung and I will be having words.

Well, it would certainly not be the first time an EDID was lies. Believe me (and Wo0zy will back me up on this), having helped a bunch of people try to transfer EDIDs to DTDs and thence to usable resolutions, the number of EDIDs which are just plain wrong is amazing.

Okay, I tried tweaking the pixel clock both up and down a few notches and the signal still cuts out after a few seconds. The TV's manual even states that the 1080p input is EIA/CEA-861-B compliant, so I guess I have to get on the phone with Samsung and tell them that their manual and EDID are both wrong. That should be fun.

Thanks for trying to help.

Bizarre. Don't know why the two aren't playing well with one another. That fact that you get several seconds of good picture before it dies just adds to the nuttiness-- it's obvious it's transmitting right or you wouldn't get anything from other monitors, and it's obvious it's receiving right or you wouldn't get 1080p60 from other sources. If the timings were that off, you'd get a distorted picture.

Try

F3 39 80 18 71 38 2D 40 58 2C 45 00 00 00 00 00 00 1E

It's not 60Hz, it's 59.94Hz and might work better.

Rather than runnning the risk of trying to create a DTD from scratch, I did a bit of digging and found an old post from Archibael on the Intel Software Community forum where he was helping someone else with a 6710b laptop.

The resolution they were working on was 1280x800 which is 16:10 so hopefully this will be OK for your Dad.

The DTD is 9A 20 00 90 51 20 1C 30 40 88 13 00 00 00 00 00 00 1C

Put this DTD in place of the current values under DTD_1 in the ini. Don't forget to comma separate and add 37,01 to the end

Archibael also points out that this resolution may not be allowed by the video bios so just in case also add

9A 20 F8 98 41 20 1C 30 40 88 13 00 00 00 00 00 00 1C to DTD_2. This is 1272x800.

Change the TotalDTDCount to "2" so that both options will be available when you reinstall the drivers.

Good luck.

Wo0zy

Hey I changed those values and sent him the new file to install.
I made him go to update driver and did it that way. All seemed to go ok but the resolutions still arn't appearing in the display properties. The only other thing i could see was that the monitor type installed was "Plug and play" could this affect this?
Thanks
Stu

Unlikely Stu.

Could be a video bios issue but I would have thought the 1272x800 resolution would at least show up if that was the case.

If you just did a driver update through device manager then it's possible that the new ini file didn't get read. I would suggest removing the drivers (through control panel) and then reinstalling (ensuring that the new ini file is in the driver installation folder obviously ).

If that doesn't work you could either get him to install DTDCalc or manually add the DTD's to the registry. DTDCalc would be quite simple to use as you already have the DTD's. If you go for the registry method you'll need to search for all instances of DTD_1 and change the values to your first DTD then search for all instances of DTD_2 and change the values to your second DTD. Finally search for all instances of "TotalDTDCount" and change the value to 2.

You might find "Logmein" would be a useful tool if your Dad is nervous about either DTDCalc or Reg editing.

If you want us to check the new ini please feel free to post it.

Hey woozy thanks for all you help so far.
I got him to install logmein and dtd calc.. i've added the dtd you've supplied me to the registry. They still don't appear, I also went in and check the registry to see if they were there and they are.... im lost

Sorry to hear that

Other than a full driver reinstallation I really don't know what else to suggest.

What language is the OS installed as? I assume English from your posts but non-english installs appear to have this problem occasionally.

Have you "un-ticked" the "Hide Modes..." button under Display>Advanced>Monitor?
