Windows 7 Not Detecting Display Resolution?

Aug 1, 2012

I have a Toshiba LED TV that I use as a secondary display. Up until today, it worked fine at 1920x1080. Now for some reason Windows is detecting it as a generic UPNP display and it it only let's me set it up to 1600x900. I have tried installing updates and drivers, but I cannot fix it.

I reinstalled windows 7 and everything was working fine until today i opened my computer and suddenly screen resolution was changed automatically.

Page Failed To Load - Changing Windows 7 64bit Display Resolution?

Apr 28, 2012

Win 7-64 on Gateway FX6860 i7 system 8gm ram tons of HD space. Got "Page Failed to Load" error attempting to change my Windows 7-64bit display resolution. This used to work, but no more ( don't know what might have caused it). I ran "sfc /scannow". SFC reported that there were corrupted files that could not be repaired or replaced and to look at CBS.log. I did but can make no sense out of it.

Can't Get Monitor To Display Same Resolution Between 2 Workspaces

Jan 11, 2013

Can't get monitor to display same resolution between 2 workspaces - Microsoft Community Copy/paste of text in OP (posted Nov 21, 2012): Ok, so here's my setup:HP EliteBook 6930p with ATI Radeon HD 3450 graphics card. Win 7 Pro 32 bit installed.I have 2 workspaces, both with docking stations.Workspace 1 (primary work site) had 24" wide (primary monitor) and 19" wide monitors.Resolutions that Windows let me set were 1920x1080 and 1440x900, respectively. These monitors were also hooked to the docking station via DVI and VGA cables, respectively.Workspace 2 had a 19" standard monitor (1280x1024, VGA, set as primary) and then I would open the laptop beside it for the dual monitor (1280x800).Today I have pulled the 19" wide from workspace 1 to replace the 19" standard at workspace 2. Windows, however, will only let me set the resolution to 1280x720 (still using VGA). Even taking off the "hide modes" option or going into the ATI Catalyst Control center to try and force it does not work. I've also tried switching between which one is primary or even making it single monitor display (on the 19" wide). 1440x900 is simply not available.

Resolution Settings Dual Display Problem

Aug 10, 2009

I have a dual head setup that works ok. My issue though is that whenever I do a reboot, I have to go into display resolution settings and re-enable "extend" displays.

Is there a way to make this persistent? It's just annoying doing a reboot and having to spend time re-organizing your desktop every time.

Apple 30" Cinema Display Resolution

Nov 22, 2010

I used to use a MBP as my main computer, coupled with a 30" Apple Cinema Display (Model A1083 - purchased three years ago). I recently purchased a PC (i7-950 3.06 GHz; AMD Radeon HD 6850 1GB; Windows 7 Home Premium 64-bit) to use as my home computer, and the MBP for mobile purposes. However, I cannot get the new PC to recognize the native resolution of the Apple Cinema Display (2560x1600). The monitor shows a maximum display resolution of 1200x800. I am using the only connection the monitor has to hook into the PC -- DVI-D Dual Link.In the screen options, under Control Panel, it shows the monitor as "CINEMA" but the drivers reflect "Generic PnP monitor".

From what I can discern, people used to use WinACD (WinACD | Download WinACD software for free at SourceForge.net) as a fix for this common issue, but the file has been discontinued and the last version was made for WindowsXP.

Extended Display Resolution Showing Different Things

Feb 2, 2012

My daughter is a teacher and just got a new smart board installed. She has a Epson projector hooked up and can only get duplicate as an option in Windows 7. It will not let her use the projector as an extended display. She need to be able to change resolutions on each desktop as her laptop is wide screen at 16:10 and her smart screen is 4:3 ratio. She is a math teacher and needs to be able to make correct circles and graphs on both, one has circle while the other displays an oval. I have changed the resolution and can get one or the other to work right, but not both. As far as I know the only way to have different resolutions on each is with extended display.

Unable To Find A Single Resolution That Will Provide A Good Display On All Websites

Nov 1, 2011

I am unable to find a single resolution that will provide a good display on all websites. As a result I am adjusting it when moving from one site to another. Not difficult to do, but if I could rid myself of this chore, it would be great. Problems are wrong screen size and garbled text.WIN 7 premium, 64 bit, using 32 bit IE9 due to the lack of a flash player that will work on 64 bit IE9.

Resolution Is Not Giving High Resolution

Sep 10, 2011

I have Dell Optiplex GX260 system. I intalled Windows 7 Ultimate on that. The resolution of screen is fine but it is not supporting 1280 x 1024 resolution and videos are not playing properly. It was not taking audio drivers as well but when I ran the SoundMax drivers for XP in compatibility mode they were installed. But display drivers are not getting installed. I even tried the various driver from Nvidia for XP/Vista/Win 7, but none of them works.

Windows 7 Not Detecting HDD

Jun 14, 2012

My brother was trying to restore his friends laptop and during the process the power got disconnected and the C Drive got wiped--I believe. I decided to fix it I would do a fresh install of Windows 7.

Everything was going great and I got the recovery disk to install, but my problem was the Hard drive wasn't showing up as unallocated disk space. The drive did show up, but not as any free space. I tried to do some tutorials in diskpart to fix the drive, but to no avail.

Now, I can't even get windows, or BIOS to detect the drive. The last diskpart command I did was to reformat it. It wasn't the quick reformat, but the one that takes an extremely long time. That's when I noticed it wasn't detecting anymore.

Here's some pics of what I'm seeing:

Windows 7 Not Detecting Usb Devices

Aug 30, 2011

I've lost all my usb drivers and windows will not connect or recognize any usb device when I install it. Here's the message I get from device manager:Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39). I've tried everything possible to correct the situation even reloading the intel chipset from Asus web site. Windows no longer will detect a flash drive or external usb drive. I'm at the end of my rope and I don't envy the thoughts of a reinstall. Is there a way to reinstall the usb drivers?Any one can point me in a direction.

Windows 7 Not Detecting Monitor Using VGA Input?

Jan 12, 2012

My new PC with windows 7 won't detect my old Acer v243w monitor. I was hoping to use dual monitors, with this monitor connected via vga into the motherboard and my other monitor connected by DVI into the graphics card. The graphics card I am using is a Radeon HD6870. It has DVI slots and an HDMI slot but no VGA slot.

Even when the Acer is plugged into the motherboard by itself using VGA it does not get detected then either.

Is it simply a case of getting a lead which will convert my VGA lead from the Acer monitor into a DVI output which I can then plug into the graphics card?

Or perhaps there is a way of enabling VGA support, maybe via the graphics card or something? It seems odd to have a VGA socket in the motherboard if it is not going to work.
