Not able to set a resolution below 4k on 4kTV

[RGeig]

Hello,

I have a strange bug with the last 3 or 4 drivers with Intel 4600 from a

Intel Core i5-4590T CPU (Win7x64).

I connect the HDMI-out to a 4k TV, but I only want 2k (1920x1080 60Hz) resolution because 4k is

only supported with 30Hz.

But the resolution output is always 4k. If I change it to 1920x1080 the resolution stays at 4k but the

picture is smaller (1920x1080) with a black border around it.

I can scale/stretch the picture in the Intel utility to full screen, but it always stays at 4k.

Even if I try to override it with "Show all settings" in the display driver and select 1920x1080x32 60Hz

I can not get a normal 1920x1080 60Hz resolution. It change automatically to 4k with 60Hz which results in a scrambled picture 😞

The only driver which was working was one from 2014 with manual override.

Is this a known issue ?

I would recommend testing our beta driver version 4206 and let us know your findings.

I just tried it.

Now it is a little bit better.

After the installation of the beta driver the picture was OK. Perhaps because of the setting of the old driver.

Changing it to another resolution like 1600*900 for testing results in a stretched 1920*1080 picture.

Changing it back to 1920*1080 is goes back to 4k with a stretched 1920*1080 picture 😞

After being one time to 4k it doesn't matter witch resolution is selected. The output is always 4k.

But the manual override woks with this beta.

Using "show all modi" and selecting 1920*1080*32 60Hz show a real 1920*1080 resolution with 60Hz.

Some improvement, but not fixed.
