How to solve HD 4600 massive repainting problems?

[idata]

Dear all,

we bought a new laptop with i7 4712MQ technology, and HD 4600 operating as graphics device.

We have serious repainting problems.

What happens lookslike this:

application starts, then is scaled to only an upper left part of the display, though in full screen mode (maximized).

I changed starting mode of the application form to "central screen" and "normal size", but the calculated centre then is not the centre of the display but the centre of the very same upper left part of the display as before.

Every next form/screen is then scaled to full window, using also the full display. But fonts are looking a bit strange, some being scaled down, others not.

From now on, only those parts of the screen will be repainted correctly, which are in the same upper left area of the display as is/was the starting form.

I will attach some screenshots to demonstrate the problem.

OS is 8.1 pro, x64, all updates installed. Used Intel Driver Update 2.5 to update graphics drivers to v win64_153631.4414 (OEM had 10.18.14.4294 on board).

Problems were with 10.18.... and with the current 153631.

So far, problems only show in WinForm-Apps designed with Visual Studio, but there is not much on the machine besides VS, ie, Firefox....

VS itself is running fine, no repainting problems. But it's next to impossible to debug the application or to run it as stand-alone .net application.

The same configuration runs fine on machines with other graphics devices, including "onboard/shared memory" type, so I am reluctant in assuming it's a VisualStudio/WinForms/.net problem.

I tried all possible combinations of scaling or not the display and reverted back to "default settings" after none of these proved to be of any help.

What can I do?

It's pretty much impossible to work seriously like this.

Thank you very much in advance,

André

Hi Andre_Knappstein,

Please try with this method, installing the latest driver manually.

Hellen,

thank you very much for your time dealing with our problems.

Unfortunately, I have been unsuccessful in installing the recommended driver. As far as I understand, it requires Windows 10 as prerequisite.

Consequently, it has not been recognized by the "update driver" method accessible according to the how-to-sheet you provided.

Manually executing the setup of the 15.40 driver yields "system minimum requirements not met for this software" (translated by me from German message...)

We are operating on 8.1 pro on a board with haswell architecture (4th Gen) i7-4712 MQ

For that architecture, it seems that 15.36 is the latest usable branch and we already installed that.

If you have any further idea on what we could try to solve this, please advise.

If no other options are left, I am willing, for a test, to upgrade to Win10, just to see if that fixes the problems, but would then have to return the laptops to the supplier and exchange them for other models, since we can't upgrade company systems to Win-10 now.

Thanks in advance,

André

Hi Andre_Knappstein,

It is important to mention that we sell our Intel chipsets and processors to third party manufacturers and they design their own computers with their own features, settings and capabilities. For that reason they design their own drivers, to meet the exact specifications on their computers. I recommend you install the latest customized driver released by your manufacture. Also I would suggest you to make sure that your Laptop has the latest BIOS version, and chipset driver. Regards,Hellen.

Hi Andre_Knappstein,

Thought I would just check in and find out if you were able to resolve this issue. Regards,Hellen.

Hellen,

thanks for asking, but unfortunately no progress here.

I re-installed the device using the OE M's "drivers and utilities DVD", checked for further updates and there were none.

Problems persist.

Contacting the OEM (Terra) probably is not worth a try, why should they deal with retail customers.

I contacted the reseller, but did not receive any answer so far.

My resources for wasting time on that options are limited; in the end we will probably have to sue them for exchanging the device for a better configurated device.

We can't use that device as is. Imagine you go into presentation with potential customers and your screens scrabble like that... you won't make a single contract.

We have some 200 devices and I found out that this is indeed the one-and-only with this Intel HD Graphics, and also the first and most likely last we ever bought from that OEM.

If there is any solution or final resolution, I will post again here.
