Dell Ultrasharp Monitor too bright?

Most Dell customers are calling Dell Technical support complaining that their monitors are too bright, even though the monitor's brightness settings are set to zero. And even if the technical support would replace the monitor, still same issue.

I've tested Dell UltraSharp 2408WFP, one thing I do noticed is, since it's ultrasharp, the picture is really crisp and yes, bright.

I've tried to see it for myself. Here's the specs of the computer I used.

MSI GX620.
Processor: Intel Core 2 Duo P8400
Memory: 4GB DDR2, 800
Video Card: Nvidia 9600MGT
OS: Windows Vista Home Premium 32-bit

The results. The monitor's brightness settings are set to zero, and still it's too bright.

The thing that i found is, most video cards are not designed for ultrasharp monitors, so technically the brightness settings of the video card is set to 50%.

I tried to lower the video card brightness settings to zero then adjusted the brightness settings of the monitor to my preferred settings, then viola, everything's pleasurable to my eyes.

All video cards have independent brightness settings.
For Nvidia you can access the Nvidia controll panel
For ATI you can access the Catalyst Control Center
For Intel you can access the display settings.

Hope these would help you. Because replacing the monitor won't fix the issue, since the monitor is working as designed.

A Quick Look at ATI 5870


The battle continues between ATI and NVIDIA.
With Nvidia's GTX 295, ATI's 4870x2 was far left behind gaming graphics card market.

ATI's big come back? Sept. 23, 2009.
I know my blog is a bit late. kindda busy at work. But anyways, i was able to get my hands on this monster card. and I can say, as soon as ATI would release the x2 version of this monster. Nvidia's GTX295 will be eaten alive. But I don't think Nvidia would give the crown that easy.
I saw in other forums that Nvidia is now developing their 300 series video cards.

Here's the quick peek on ATI's 5870 features and specifications.

Windows Update Causing STOP Error 0x0000007E

Windows update KB973879 has been pulled from Windows Update and is being worked on.

For now simple system restore should fix the issue, else uninstall this update by booting to safe mode.

Issue: System blue screens either when disconnecting a USB device, using safely remove hardware or when system is resuming from standby/idle state.

Workaround: Uninstalling windows update KB973879 and hiding this update from available update is currently seem to be fixing the issue.

In case if removing update KB973879 doesn’t fix the issue, we need to remove remaining two updates KB970653 and KB972036.
