samsung spf-72h display panel stuck

Recommended Posts

Hi all,

 

I'm new to your forums here. I would like to receive some assistance for a problem I have with Aida64 and the Samsung LCD plugin.

 

I've recently purchased a Samsung spf-72h LCD screen panel for use with Aida64. However, after setting up the panel and installing the drivers for the operation system, the device get's stuck after serveral minutes. The is a recurring situation. The operation system is Windows home server 2011 and the Aida version is 5.7.

 

The display panel itself is working fine but the problem is that is get's stuck after a while. It works fine and smooth for a couple of minutes. After the device is stuck, I need to restart Aida64.

 

Firmware in use: M-CE7AS1WW-1004.0

LibUSB driver: LibUSB-Win32 v1.2.6.0

 

Is anybody able to assist me with this problem?

 

Thanks in advance.

 

Regards,

 

Ken

Ok, thanks for the infomation.

 

Is there nothing I can do to resolve this?

 

Higher compression level en lower refresh rate for instance?

I think those could help. It's definitely worth fiddling around with it a bit, maybe you can find an optimal setting where it keeps working for hours without issues.

That doesn't help, even with compression level to the highest setting. Setting the refresh rate to 500 ms doesn't help either.

 

Does it actually mean that this device in in your compatiblity list and doesn't work properly at all?

Samsung SPF devices are very odd, and we have exactly zero documentation on them. What we do in AIDA64 is using a trick that the mini-monitor software (by Samsung) uses. It should work on all SPF devices we've listed, but we cannot guarantee that all devices with all firmware combinations work flawlessly. Maybe yours have a defect (either a hardware defect or a firmware issue) that causes your device to work unreliably. Maybe it's overheating -- and maybe it would work exactly same way with Samsung's mini-monitor mode as well. It's not possible to diagnose that remotely I'm afraid :(

Ok, thanks for the information again.

 

Is there another brand/device which you can recommend for usage with Aida64?

 

Preferably between 4.3 inch and 7 inch, with at least a resolution of 640x480

 

Thanks.

I'm afraid there aren't many active (currently sold) devices on the market that falls into that category :( So we generally recommend using an old Android tablet or iPad for such purpose.

But I'm glad you've managed to make it work with a more relaxed update frequency ;)

I also have a SPF-72H (LP07CELSS).
After a firmware update to 1012 everything worked fine. No overheating (display refreshes every 1.1 seconds). Is it possible to shorten the interval or is it already completely exhausted?


Very important info for all. Do NOT install Samsung Frame Manager for Vista 64-bit v2.00 on Windows 10 64Bit v1809 (Build 17763.292) on any CASE. You will get a BSOD and you will have to reinstall the operating system.

 

Edit:

I noticed that the SPF-72H hangs at irregular intervals. When the case arrives you have to switch it off and on again so that it continues to run properly. But I don't find the frame to be above average warm. I am therefore not very sure that it is due to overheating.

In case you have a low update frequency configured, but the refresh rate is still rather long (over 1 second), it means the Samsung USB protocol is the bottleneck.  I'm afraid we cannot fix it from our side.

As for the hanging, it could still be due to overheating in case the controller chip inside gets too warm and the heat is not transferred properly out of the frame PCB.  Disassembling the frame and directly inspecting the chip's thermal state during operation would be a good idea, but I'm not sure if you can disassemble the frame easily at home...

I screwed on the case of my SPD-72H and exposed the circuit board. You can touch the chips with your bare hand without any risk of burning.
I am convinced that the problem is not caused by overheating.

Too bad, I think the SPF-72H should be on the list of non-functioning picture frames.

I'm sorry to hear that SPF-72H fails to provide a stable mini-monitor mode function.  We'll add a warning to the AIDA64 LCD Guide about this.

I am now trying to play a little at the update frequency. Now set it to 1200ms, if necessary I will increase it step by step by 100ms.
