SN75DP126: some problems with the TS3DV642 and SN75DP126 applications

Kevin

Would you please send me the SN75DP126 and TS3DV642 schematic?

Thanks

David

Hi David,

I already have a message to you ,please check.

thanks

Kevin

Kevin

Does the issue with the DP or the HDMI path?

Thanks

David

Hi David

Please check message , thanks

Kevin

Kevin

I saw the schematic and it looked good, does the issue happen with the DP or the HDMI path?

Thanks

David

Hi David,

Yes, DP/HDMI will happen.

thanks

Kevin

Kevin

Does the issue happen with other resolution or only this resolution? And does this issue happen with other monitors or just one particular monitor?

Can you probe HPD_SOURCE pin (pin 19) of DP126 and see if it goes low when there is a black screen?

Thanks

David

With behavior different from system to system, I don't think this is a DP126 hardware issue. Looking at the UL Benchmark website:

I'm having stability issues when running loop testing and get error about display resolution changing.

While the loop tickbox in Custom tab does disable most of the anti-tampering checks, when loop testing for hours in full screen mode, the run can be interrupted if some background application draws a popup or task bar notification as it causes a switch back to the desktop view. 3DMark cannot recover from such display mode change.

For very long stability stress tests we recommend testing using the windowed mode. Windowed mode is not interrupted by task bar popups or other interrupts from background applications, only actual driver crashes or general system instability will stop the test. When looping all parts of a test, there are loading screens with light load between each part. For maximum load set the stress test loop to loop a single part of a test - Fire Strike Game Test 1, for example - and the loop will be continous without loading screens. Note that when looping, the run will never produce a score.

Also we recommend disabling Scan Systeminfo from the help tab for loop testing - you are not going to get a result file anyway, so there is little point in gathering hardware data and in very long loops the hardware monitoring dataset (temperatures, clock frequencies etc.) can be so large that it could in theory cause stability problems.

I would reach out to UL Benchmark for their support as well.

Thanks

ok, thanks David great support.

Hi David,

Is there any progress update in UL Benchmark?

thanks

Hi David,

How do contact UL Benchmark for SW update support?
Designing the product?
Or TI ?

thanks
