To all users of SPFs: I found the way how to control SPF brightness. I found the way how to switch back to storage mode after AIDA exit (however developer already knew it). I send this to developer

Would be great to add it next to the jpg 0-99 field ^^

Try to lower the compression setting even more, and see if it helps. As for the LibUsb drivers: you can only install them when the SPF device is in mini-monitor mode. Try to remove the Samsung drive

Ok I will ask them. What kind of data can you process to put it on the photo frame  ?

AIDA64 was originally designed to monitor sensor readings (temperatures, voltages, fan speeds), but later it got extended to cover generic system readings like CPU core clock speed and RAM utilization. We've already exceeded the original goal of the hardware monitoring module, but we're up to adding more features as long as they are about monitoring a certain system state or property. Passing the output of another software to an external LCD doesn't fall in that category :) That other software should be responsible of outputting its displayed data to the external screen.

Possible malfunctions my PhotoFrame. I removed the driver samsung PhotoFrame continues to work with the drivers LibUsb. As soon as I turn off the photo frame and then turn on again LibUsb driver no longer see her.

I also noticed that the Frame does not store the setting after turning off. For example install a brightness level of 100%, turn off - turn the brightness to 80%. It is also very often a window pops up with the demand to format the memory of the photo frame. I'll try to update the firmware hope this will fix the problem.

The problem was in the photo frame. I bought another similar model, and after removing the drivers samsung she continues to work.

 

How to find out the maximum image size that can take a PhotoFrame? Model SPF -72H. Please explain to what gives change parameter HWMonSPLCDJPEGLimit?

 

 

created new skin :)

JPEG limit is only need to be configured when there's an issue while using complicated LCD layouts. Do you find any issues with your old or new layout?

I can not understand the reason why the photo frame freezes. It can work stably and 5 minutes and 5 hours! Then, the image freezes and sometimes there are artifacts.
When I used HWMonSPLCDJPEGLimit parameter with a value of 120-200 seemed to me that the photo frame runs longer. If I use compression degrades picture quality and photo frame freezes often.
This problem occurs on the old and the new photo frame.
There is a suspicion that the photo frame is overheating! I'll try to come up with cooling.

The way it works is that each of those Samsung SPF devices have a limit of a certain maximum JPEG file size. If you pass a bigger file, they will malfunction, and you have to reset them to make them work again. The problem with JPEG is that it's not easy to predict the resulting file size from the input bitmap. So when you specify a JPEG quality of e.g. 80%, the resulting file may be 200KB or 210KB or 180KB, depending on how complex the rendered bitmap is. And since with AIDA64 you can build a dynamic layout, one that may look less complicated or more complicated, depending on the system state, it's not easy to find a proper JPEG quality setting. Sometimes 80% would work for hours, but then a frame comes where the 80% setting yields into a bigger JPEG file, and then the frame freezes. That's why we've introduced the JPEG file size limiter, that will automatically lower the JPEG quality in case the resulting file gets too large. The problem with that setting is that you have to play with it a lot to find the right size for your SPF device. Samsung sadly doesn't publish that data, and AFAIK there's no information on that on the internet anywhere either :(

Perhaps the problem in all SPF-72H models. I have installed a different compression quality and at 10% it still freezes. I deleted all the pictures and leave only the clock and it still freezes.

It is possible of course. SPF-72H is one of the oldest SPF series devices, so it may not work as reliably as newer models like SPF-87H and 800P :(

I found out why the photo frame freezes! The culprit turned out to be a bar!
When I removed all the bars freezes stopped!

Sounds interesting. And also, it doesn't really make much sense :) Unless by removing some visual elements the JPEG image size falls under a certain limit where the device stops failing ;)

I removed the other elements. Problem still exists! But when I removed the bars freezes stopped! For me it's just a mystery, but true!
I'll draw the bars and add these elements through the  item "gauge". I want to test my theory!
 
I hastened to conclusions! Was wrong! One photo frame hung after 14 hours, the second after 10 hours. Deleting bars affect the duration of the work, but did not fix the problem! I noticed another feature when the photo frame freezes after the next turn, it does not work for long. Last my guess - overheating. I'll try to arrange cooling, see what happens.

Every time the photo frame (spf-87h) is powered on, the following menu pops up and we have to choose one by hand. Is there any way to make it into mass storage mode or monitor mode automatically?

AFAIK there's no way to automatically turn the frame on into a certain mode of use. This is a firmware limitation of the SPF device :(

Same issue with the SPF-83H.

 

I will open the back and see if reducing the heat helps reducing the amount of freeze.

I found out the causes freezes!
1. Overheating. This problem, I decided to gluing radiators on the chips. Also I removed the back cover.
2. usb cable length. I had two cables, one 2.5 meters, another 1.5 meters. With a short cable Photo Frame longer worked. I bought a cable even shorter by 0.6 meters and Photo Frame became very rarely freezes. Perhaps if the cable is connected directly to the computer's motherboard and reduce its length to 0.4 meters the photo frame will work stably.

Hi, removing the back cover means that the power buttons and so on are dandling, not neat.

I noticed that heats makes it crash.

 

I cut a piece of plastic to let the lcd breath ^^

^That's a very nice config you have there. :)

 

Hi everyone,

 

What's the latest model Samsung DPF that's supported and available to purchase right now? Preferably Black + 8~12"

 

Thank you

AFAIK none of them are produced anymore, so you cannot get them brand new anymore. The last series consisted of the 800P, 1000P, 800W and 1000W models. I'm not sure if the "W" version was a successor to the "P" version though.

Great that works fine.

would be good to add in the import windows the *.splcd.axlcd filter on top of the existing *.sensorpanel

It's not really that straightforward. Those files are not 100% compatible with each other. That's because LCD layouts can have multiple pages, while the SensorPanel layout can only have one page. So if you design a multi-page LCD layout and you import it as a SensorPanel layout, your pages will be joined and several of the LCD items may overlap with each other. In which case you need to re-adjust the positions of those items to fix it up.

      hi all, newbie here! this is my first post so i hope it has landed in the correct place..  be gentle!

      i have installed the 'simple' version of a64, is it possible to run multiple instances of the sensor panel? i have the sensor panel running in a 5 inch screen located inside my case but have a room change planned which will put the case high on a shelf out of my eye sight so i would like a second display for stats placed under my main monitor. i plan to use a larger screen say a 10.1 'ultrawide (if thats the correct term) as i like the extra real-estate. what are my options?
      on a similar topic, is it possible to create an 'unpublished' senor panel before removing the currently used panel? or would i have to save the current panel to file or something then start a new panel?
      also can anyone point me to gauge resources, ie pre made gauges? or an easy to understand tutorial for how to diy them? total novice here, but can follow an idiots guide!

      i have included the final evolution of my first attempt using the provided gauges etc, it took me ages to get rid of the green dials.. i finally gave up trying to figure it out in a64 so i just changed the hue on the 5inch monitor lol. really hoping to learn the skills to create something like i have seen on here.. some really nice work on the share your panel thread, some of those must have taken ages!!! impressive. 
      any advice greatly received, but remember your talking to an a64 absolute novice!!
      Thanks folks.

      Hey guys!
      Im hoping for some input regarding my question. I saw, AIDA64 is supporting a lot of different displays and interfaces. Now which one to choose? Heres some more input from me about what im looking for:
      [Mandatory] 5-8 inch LCD display [Mandatory] only USB powered [Mandatory] black frame design to match my case, if possible [Optional] A flat, not too thick one [Optional] small bezels if possible [Optional] No buttons neccessary, i want to place it inside of my case. [Optional] an internal USB connector to directly connect it to the motherboard At the moment im using some Aquacomputer Vision OLEDs which are working fine. But i can already see some burn in and they are pretty small. Since theres no LCD coming from Aquacomputer anytime soon, im thinking about using AIDA64 to get my data on screen. I have 3 of those OLED on each of the drive bay covers, this is more or less the space i have available
      I have attached a screenshot of the system with the OLEDs and their current placement for you to visualize.
       
      Thank you for your suggestions!

      Hey there,
      Installed the new card but i do not see all the sensors, like i did on my 2080 ti.
      Also, when the GPU is idle (low clock) the GPU Clock field on my sensor panel and LCD appear and disappear sometime. Also,
      app takes way longer to load.
      If any logs are needed just let me know.
      Cheers!

      Hey, new to Aida64 so be gentle,
      I have 2 Raspberry Pi 7" touchscreen display. One has a pi connected to it and the other is just the panel. The panel has just a usb port and a micro usb port. What's the easiest way to get this up and running as an external monitor? I've been running ModBros but I'm looking for something more customizable. 
       
      Also, other then the one forum post, is there anywhere to get templets to get a start from and build off of that?
