Washed Out Color With NVIDIA Graphics

I recently purchased a brand new ASUS VE278H 27" LED-backlit monitor.

While a wonderfully big and bright display (especially paired with my NVIDIA GeForce GTX 1060 video card), once set up (using the DVI interface) dark colors, particularly blues and blacks, appeared washed out.

BEFORE: Blue / black wallpaper on DVI, note the rather nasty gradients.

After some research (most of which seemed to focus on display issues related to using the HDMI interface), I did find a solution which seemed to help in my case.

Generally with NVIDIA I install their Control Panel to tweak cards with an NVIDIA chipset. There's a setting under Display => Change Resolution called Output Dynamic Range which purports to preserve shadow and highlight details.

By default this setting is "Limited", but by changing it to "Full" and then clicking Apply, I was rewarded with the beautifully silky-smooth blues and blacks I expected.

AFTER: Significantly richer, silkier color.

Why not have this set to Full by default? It is a mystery for NVIDIA to address. 🤔

LogMeIn Laptop Screen Stays Blank After Remote Session

LogMeIn is an excellent online service which offers a free method of remotely controlling a PC via web browser. 

Recently I encountered a minor glitch, however, and whether LogMeIn or Windows 7 or nVidia are the culprit, I'm not sure.

I had remoted in to my Dell Latitude E6410 laptop using the latest free version of LogMeIn. It is equipped with Windows 7 64-bit and NVIDIA NVS 3100M display adapter, each with the latest updates and drivers available. 

All seemed fine via remote, but when I returned to the office I found that although my secondary monitor activated normally, my laptop display remained seemingly asleep and unresponsive. I tried using the key combination of the Windows key and P then clicked Extend to try to have Windows reinitialize the displays and wake everything up, but no joy.

I then tried just changing one of my Display settings, the Resolution, to a different value in order to have Windows enable the Apply button, and then clicked it. 

After doing this, my laptop screen was no longer blank.

Dell Latitude E6410 Sound Problems

The time came a few months back at my workplace to replace my venerable Dell Latitude D800 with something newer, better, faster. That replacement arrived in the form of the Dell Latitude E6410.

Dell Latitude E6410

Featuring an Intel Core i5 64-bit CPU, 8 GB of RAM, and Windows 7 Pro, I expected great things, and in many respects, I got them. Performance was leaps and bounds ahead of my old D800; tasks that my D800 plodded through like building and debugging an ASP.NET / C# website or searching through thousands of files in my local source repository proceeded many times more quickly. 

Unfortunately, I was dismayed to discover that the sound provided by the onboard IDT HD92xxx device, utilized by the NVIDIA NVS3100M video hardware, stuttered frequently. Whereas my old D800 never missed a beat, literally, even through the most challenging tasks, this brand-new, supposedly state-of-the-art machine couldn't play MP3 audio without hiccuping many times throughout any given track!

Apparently this is not an isolated issue. One thread on Dell's support forums described many users' similar issues with erratic sound. Various other posts online that I found blamed the IDT hardware, such as the first review listed for this related IDT product, followed by a couple of other reviews for same which immediately reminded me of good old Baghdad Bob...

"good, and very nice"

I decided to take a reverse shotgun approach, meaning rather than pump a few satisfying rounds of buckshot into my employer's laptop out of sheer aggravation, I'd run through a short list of steps based on research I'd done into the problem so far.

To visualize the problem, I downloaded and ran the DPC Latency Checker, which represented the stuttering issue in the form of the big, ugly red lines representing relatively huge latency leading to stuttering audio.

If I were typing the way the audio stutters, it miiiight look liiiike ttttthhhis.

Dell Latitude E6410 driver download page
on Dell's support site was my first stop. I downloaded the latest available drivers and installed them, including those for audio, video, chipset, and even the touchpad. Following the experiences related by others in the Dell support forum, I also updated to the latest BIOS.

Updating the BIOS, as described in the Dell support forum thread, helped things somewhat, but the stutter was still recurring intermittently. I also completely uninstalled Dell ControlPoint System Manager, which I noticed made the stutter markedly worse when active.

I also tried using PowerMizer Manager, a free utility which lets you control and, if desired, prevent your video adapter from downshifting performance based on demand, which can cause undesired latency.

Most recently, though, after installing the latest drivers supporting the NVS 3100M from NVidia's driver download site, I've found that the stutter has improved significantly. Now, the DPC utility shows that latency is overall much improved, but still the stutter occasionally rears its ugly head.

Definitely better than before.

In summary, here are some suggestions if audio stutters on your Dell Latitude E6410:
