What model Sony TV are you using?
I have a Bravia KDL-32LL150 w/software v. 1.014
Thanks, we are investigating this.
I am experiencing the same problem. I have a Gigabyte Z77 motherboard (not sure what model), i7 3770K connected to a Samsung SyncMaster 2443 monitor.
Thank you for your help!
I have not determined a solution using the HD4000 graphics in my set up, and yours is the first response in nearly 3 weeks to my post.
I have to have my KVM, and needed to move forward, so I added a graphics adapter (HD7750 from XFX). That adapter, and it's drivers, function correctly, and have since installation. It is not expensive ($100+-), but still irritating to have to purchase it since I "paid" for graphics at the needed level in the CPU/Motherboard combo. The wheels of progress turn slowly though and I can't wait.
I have never seen this behavior in any other graphics combination. Besides my in-house needs, I use the KVM to connect systems I'm working on (for malware removal or such) and for set up and loading new systems, so there have been dozens of variations.
Hopefully Intel will find some answer, someday.
Good luck to us all!
After posting here, I did some more research and found a reg hack that seems to work, at least for now. I edited a couple of values in the following key. Keep in mind my monitor has a 16x10 aspect ratio and 1920x1200 is its native resolution.
DWORD value PrimSurfSize.cx = 1920, decimal
DWORD value PrimSurfSize.cy = 1200, decimal
According to the post I found, it doesn't solve everyone's problem, but it seems to work for me.
I'm still hoping Intel will come up with a proper and permanent solution. I use an 8 port KVM to work on seven PCs, and while I have nVidia, ATI and Intel video, this is the first time I have experienced this problem.
We have identified the cause of the issue and are currently working on a solution to resolve it. I will post updates here as more information becomes available.
you are my hero !
I have had that boring issue with my HD4000 and an ASUS VK266H Monitor as well.
On my 2 other machines with Windows 8 Pro x64 and Ubuntu x64 and different GPUs also attached to the KVM switch I did not have such problems.
Thank you very much for your posting, your solution is working for me - you made my day :-)
Robert_U - do you have any updates for us? We would all benefit from a driver that allows the use of a KVM. We want to see that the display resolution settings remain fixed.
Looking forward to a solution!
I have the same issue on a HP Elitebook 8470p/WIN 7 64 bit/HD 4000 Driver version 18.104.22.16812 (3/26/2012) connected to a KVM. I am also hoping to run this laptop in dual-monitor mode. The odd thing is that when I switch to another computer on the KVM, the laptop suddenly thinks that the monitor is connected and all display settings return to what I want on the laptop while I am connected to another computer. The driver appears to be recognizing the opposite. (shows proper settings when I am connected to another computer and reverts to 1024X768 when selected)
I installed the new driver version 22.214.171.12471 (3/19/2013), rebooted and now I cannot set a higher resolution (max = 1366x768) on the larger display (Samsung 245BW). The Intel Graphics Control panel can't even recognize the type of display connected!!
Next, I downloaded and installed a previous version - 126.96.36.19932 (12/12/2012) - At least I got my resolution options back for the larger monitor! Unfortunately, the system will not keep the display resolution settings. NOTE: I have 2 other HP laptops with Radeon HD 6470M display adapters that do not have this problem. If Intel can fix this issue, I will be come a fan. If not, I will encourage HP to drop the Intel display adapters.
I have an HP ProBook 6470b with the same graphics chips and the same problem. It works fine connecting it to my LG 17" monitor directly, but when going through the KVM it eventually reverts back to some unknown configuration and won't let me pick a resolution higher than 1366x768. Every other PC on the KVM works fine, recognizes the monitor and automatically sets the correct resolution. I tried the registry changes, but they do not work in my case. Intel needs to fix this!
The latest drivers from Intel have fixed the problem for me. I am now able to enjoy my HD monitor!
The driver version is 188.8.131.5265 - you can update your drivers by going to this link:
Last weekend, I built a new computer using an Asus P8H77-I motherboard and Pentium G2130 (@3.2GHz) CPU with integrated graphics, with Windows 7 64-bit Home premium. I use a Belkin Omniview Pro2 8-way KVM, and a Samsung Syncmaster 2443BW (same as the gent above).
I experienced no issues when switching screens with the default Windows 7 video driver, but as soon as the full Intel driver is installed, I get the referenced behaviour. The "Intel HD Graphics Control Panel" shows no values under Display (everything is blank!). Screen Resolution shows ""1.Display device on: VGA" with 1024x768. If I select 1920x1200,it works fine until I switch over to another computer and back. I was also unable to install the Samsung monitor driver..
It appears to be related to monitor detection not working with the Intel driver routed through the KVM VGA.The same setup works great if one uses a direct cable from the VGA port to the monitor. It detected the monitor via PnP correctly, and I was able to install the Samsung monitor driver.
The bad news is that this is with driver version 184.108.40.20665, dated 2013-05-07, module WIN64_15319.
Changing the default x and y resolution as mentioned above to default to 1920x1200 does work around my current issue, but I would prefer the driver be fixed rather than rely on a hack forever.
