When working with Windows VMs through VMware vSphere Client 6.0, some users encounter a frustrating display issue where portions of the guest OS interface get cut off at the bottom and right edges. This occurs in both:

• Dedicated console windows
• Tabbed console views

The problem persists regardless of:

- VM reboots
- ESXi host restarts
- Client machine reboots
- Display resolution changes
- Multi-monitor configurations

This behavior stems from a mismatch between three components:

1. The VMware Remote Console (VMRC) display scaling
2. The guest OS resolution settings
3. The HTML5 console's viewport calculations

In ESXi 6.0, the console implementation doesn't properly handle DPI scaling from modern Windows 10 systems, causing viewport miscalculations.

Method 1: Manual Resolution Adjustment

Force a compatible resolution in the VM:

1. Edit VM settings → Video card
2. Set maximum resolution to 1600x900
3. Configure Windows display settings to match
4. Check "AutoFit" in VSphere Client View menu

Method 2: Registry Hack (Windows Guests)

For Windows VMs, modify DPI scaling behavior:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontDPI]
"LogPixels"=dword:00000060

[HKEY_CURRENT_USER\Control Panel\Desktop]
"Win8DpiScaling"=dword:00000001
"LogPixels"=dword:00000060

For power users experiencing this with development environments:

# PowerShell script to auto-adjust resolution
Add-Type @"
using System;
using System.Runtime.InteropServices;
public class Resolution {
    [DllImport("user32.dll")]
    public static extern int SetDisplayConfig(
        uint numPathArrayElements,
        IntPtr pathArray,
        uint numModeArrayElements,
        IntPtr modeArray,
        uint flags
    );
}
"@

[Resolution]::SetDisplayConfig(0,$null,0,$null,4)

For production environments, consider:

• Upgrading to ESXi 6.5+ with improved console handling
• Using VMware Remote Console (VMRC) as standalone application
• Implementing Horizon View for better display management

Remember that display artifacts may temporarily reappear during VM migrations or snapshots - this is normal behavior for the 6.0 version.

When working with Windows VMs through VMware vSphere Client (version 6.0.0), many users encounter a frustrating display issue where portions of the VM's screen become inaccessible. The bottom and right edges of the virtual machine's display extend beyond the visible console area, making it impossible to interact with certain UI elements.

This issue manifests in both console viewing modes:

• New Window Console: The standalone window shows scrollbars but critical screen areas remain unreachable
• Tabbed Console: The integrated tab view crops the display without any scrollbar option

Before we dive into solutions, let's address what typically doesn't work:

// These common approaches usually fail:
1. VM reboots
2. ESXi host restarts
3. Client machine reboots
4. View -> Auto-fit settings adjustments
5. Basic resolution changes (only provides partial fixes)

Solution 1: Modify VMX Configuration File

SSH into your ESXi host and edit the VM's configuration file:

# Navigate to the VM directory
cd /vmfs/volumes/datastore1/VM_NAME/

# Edit the VMX file
vi VM_NAME.vmx

# Add these parameters:
svga.autodetect = "FALSE"
svga.maxWidth = "1280"
svga.maxHeight = "1024"
svga.vramSize = "16777216"

Solution 2: Adjust Windows Display Settings

Within the Windows VM, modify these registry settings:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{GUID}\0000]
"DefaultSettings.XResolution"=dword:00000500
"DefaultSettings.YResolution"=dword:00000400
"Attach.RelativeTo"=dword:00000001

Solution 3: Update VMware Tools

Ensure you're running the latest version of VMware Tools:

# PowerShell command to check version
Get-WmiObject -Namespace root\cimv2 -Class Win32_Product | Where-Object {$_.Name -like "*VMware Tools*"}

# Update command if outdated
msiexec /i "path_to_vmware_tools.msi" /qn

If using the HTML5 web client is an option, try accessing your VM through:

https://your-esxi-host-ip/ui

The web client often handles display scaling better than the traditional client.

After implementing any solution:

1. Completely power off the VM (not just reboot)
2. Refresh the vSphere Client inventory view
3. Verify display settings in both the VM and client
