ENVY TouchSmart 15 - j134na: TouchSmart HP ENVY 15 - j134na display flicker

display monitor began to waver a bit as he isset to 40 Hz and it is set to 60 Hz of course.

It's like that in the programs, windows and ubuntu 14.04

I do need to update the bios or something?

Thank you

Today, I finally got.
I find it unhealthy to watch the screen at 40 Hz so reinstalled windows 7 x 64 again.

The flickering started right after I installed intel driver hd 4600...

After a full day of reinstall drivers intel and nvidia I finally got.

The flickering starts when you Dim your monitor, so when it is set to 100% or 0% I did not flicker

  • HP ENVY notebook: Purge display backlight

    I bought this laptop and after I opened the box, I went for a video to see the display features. Then I noticed that there are white Spots\Screen bleeding on the edges of the screen. I have returned the laptop to the dealer and he told me it was not a fault or defect and that it would not change. Simply, they do not accept that it is an acceptable condition to replace the laptop. He agrees that this happens to a lot of products and he knew that it was the issue in its many products, but refused to return. I need advice...

    Thanks in advance...

  • HP envy 15-j104sl: display not working not properly

    Hello

    I have a Hp Envy 15-j104sl, unfortunately after a fall, the screen does not work properly: sometimes, the left part or the entire display turns white and it is impossible to use it unless I move the screen / hinges in another post.
    The glass is not broken, I think the problem may be in the base/hinges lower/some other type of contact works not very well.

    I am really disappointed with the online Hp support: I can't find location to send my laptop for repair, and I can't even call help if I have my warranty has expired.

    It's a bad display cable or possibly the display panel. It's going to not need a repair by a technician. Where do you live (country)? I'm not clear if you say your warranty is or has not expired?

  • HP Envy 7 - stupid display question whenever he loses the power of food

    I have a HP Envy 7 with double graphics chips.

    Whenever I unplug it from the power outlet, he returned to the chip of lowest power... and applications / internet page I had opened earlier becomes black.

    And if I start new applications or open new Web pages, there is a delay of 1 to 2 seconds before the screen is loaded.

    It remains like this when the power is restored, and I have to restart the computer for the sort.

    Just one of many things that I don't like this machine, but currently the most boring.

    Is this a known issue?

    Hello

    It is something that can be changed by a setting.

    Right-click on an open space in the office and select Configure switchable graphics.  In the Catalyst Control Center, remove the tick at the bow of the option switch automatically to the GPU when on battery power saving .  Now just click apply and it is changed. Close the control center.

    having the same problem as the other. Cannot get the printer to use the photo with photo tray 4 tray x 6.  But I did specify in setings to use the photo tray.  My new 5741 DID see and recognize the tray and paper but invariably printed on paper 8 x 10.  ?????  using windows 8.1 and photo gallery.

    Welcome to the HP community @fredstir,

    I read your post on your Officejet 5740 do not print to the photo thew tray and wanted to meet you with my suggestions. If you have not tried to uninstall the printer software, restart the PC and then reinstall the printer once again, try it. You can run the Installation Wizard for Windows HP printer to find and install the printer for you.

    Also see this link and try the following steps: HP ENVY, printers Officejet - display of the 'Photo Tray problem' error

    Let me know what happens when you try to print to the photo tray afterwards. Try another program to see if that makes a difference.
