HGY, Could you please attach the DX Diag report for your system? (Start -> Run -> dxdiag -> Save All Information).
- Could you also provide me the model number of the monitors you are trying to use?
- Are you using adapters, converters?
- Motherboard model number?
Dear Sylvia, the monitor is Asus VE228. The Tv is Sharp LC-52DH65E. Both have HDMI inputs. Motherboard is Asus P8Z77-V Premium which was one of the world's most expensive board. One of the cables is a DisplayPort HDMI adapter. The other output of the board is HDMI. Currently I do not use the Thunderbolt interface. The order of the displays does not matter. Theoretically this hardware is able to handle these displays as I saw this config working for one day. So this should be a driver issue. I saw lots of similar issues on the web. I am afraid I have to donate some money to AMD and the electricity supplier company by buying a video card. Thanks for any help in advance. However, I am afraid that this will be never fixed.
Here is the dxdiag output:

Thanks for the information HGy.
Would you please try using the following Graphics driver version 3945? Intel® Download Center
Are you able to get video from each monitor when using single display using the same cables and adapters?
The Displayport output does not work even in standalone just as before. However, I saw that working on this machine once even as a secondary output. The driver only saw the display attached to it once immediately after a display driver update through windows update. But even that very same driver version did not work anymore after one day. It was mentioned in some forum that this is related to a driver initialiazation problem.
Did you install the graphics driver I mentioned on my previous post?
Can you try doing a system restore on your computer to the last working state?
Yes, I did.
No, it was a long ago. Since then the system was even reinstalled with a newer windows.
It seems that you are using cables or adapters that are not being recognized on your system with the new drivers.
The recommendations I can give are the following:
- Use another display port to HDMI adapter.
- Try to use straight connection HDMI to HDMI and DP to DP
- Test another monitor or TV
- Use the graphics driver provided by Asus.
If you remember which was the driver version you were using before having this behavior please let me know. We may be able to find it so you can install it on your computer again.
We have 2 monitors connected to a system and it is working just fine, but we are using straight connection to the HDMI port and Display port outputs.
It did not work even with the very same version.
AFAIK my adapter is passive so it should have worked always or never. Only cable resistance could be an issue I guess.
Do you use DVI as the primary display? In that case it really must work AFAIK. However, it seems according to your last sentence you used HDMI and display port. Unfortunately, I cannot try it with direct links as I do not have any monitors with DP.
Hgy, I do have dual display on my laptop using a DVI to DVI cable (straight connection)
I’m going to check if we have a DVI to DP cable for testing.
According to some forums it always works when the primary output is DVI. So if it is really true it is likely that it will work for you if the adapter is not too bad.
But my motherboard does not have any DVI outputs; it only has HDMI, DisplayPort and Thunderbolt.
Let me check this behavior with the engineers.
Ok, thank you very much in advance.
