Intel Graphics Drivers - Hue issues?


I'm running Windows XP SP3.


The embedded graphics controller is the Intel GM45 Chipset / Mobile Intel 4 Series Express.


The OEM drivers (it's a Dell Inspiron 1545 laptop) are provided only up to 6.14.10.4990 (Dell driver code R203389).


I usually like to stick with OEM drivers on Dell stuff, since they often have tweaked it for the specific machine. But I needed to run an app that refused to run on the old video driver (it's dated 2009). So I went to Intel's site, downloaded the newest driver (6.14.10.5355), and installed it.


It's working fine except...the screen seems a little "warmer" than usual. I.e., my whites seems slightly reddish. Oh, its ever so slight, in fact my friend was unable to confirm, but then he doesn't look at this screen every day.


Its not enough that its 100% conclusive but it definitely seems to be a little warmer. However the gamma/hue corrections do not seem to have changed, at least the driver panel reports them the same. I'm not using any gamma profiles of any sort, just default (what you get, or don't get, with a clean XP install).


I noticed the new drivers have the ability to customize gamma on a per-color basis (RGB), while the old drivers simply had a master gamma. The new driver also allows the gamma to be set below 1.0 (previous drivers didn't). Nonetheless, all the settings still appear to be the same as before the upgrade: (Brightness: 0, Contrast: 50, Gamma: 1.0). (zero brightness is more or less centered on the slider, so it seems to be the way the driver labels the midpoint.)


Is it possible the screen is actually "warmer" with the new drivers? Or am I just imagining things? Is there any way I can test it? Preferably without buying extra fancy gizmos.


Example: I turn down the Red brightness to the point where whites look bluish, yet human skin in a photo still looks more reddish-pink than it does with the old drivers.



Answer



It's very possible to have your screen colors mess up on you. However, the only was to test the colors is fairly subjective. You can try the Lagom Monitor Tests to see if they can make a problem apparent. in particular the Lagom LCD Gamma Calibration test page may be able to help you discern if this color change is real or only a feeling.


On the other hand, what does it matter if it IS warmer if it FEELS warmer. This is not an ethical or moral issue, so follow your preference. It's your monitor and the way the picture feels to you matters more than a test. I'm somewhat color-blind in the reds and greens, but it affects pretty much entirely how I see all colors. I have my monitor set up so that it displays closer to how I actually perceive the world. Even if the monitor isn't warmer, if it feels warmer, turn it down.


Sorry, that got kind of philosophical, but hopefully that website helps concretely.

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...

linux - Extract/save a mail attachment using bash

Using normal bash tools (ie, built-ins or commonly-available command-line tools), is it possible, and how to extract/save attachments on emails? For example, say I have a nightly report which arrives via email but is a zip archive of several log files. I want to save all those zips into a backup directory. How would I accomplish that? Answer If you're aiming for portability, beware that there are several different versions of mail(1) and mailx(1) . There's a POSIX mailx command, but with very few requirements. And none of the implementations I have seem to parse attachments anyway. You might have the mpack package . Its munpack command saves all parts of a MIME message into separate files, then all you have to do is save the interesting parts and clean up the rest. There's also metamail . An equivalent of munpack is metamail -wy .

ubuntu - Why does my USB hdd returns SG_IO: bad/missing sense data?

I am able to boot and run commands from external USB hdd; the message in question appears for about 45 seconds then booting continues. GRUB2 is installed on internal HDD. When choosing to boot directly to /dev/sdb the message doesn't appear, however boot time is about the same as booting to internal HDD. /dev/sdb: Timing cached reads: 1018 MB in 2.00 seconds = 508.97 MB/sec Timing buffered disk reads: 80 MB in 3.03 seconds = 26.37 MB/sec pfeiffep@de:~$ sudo hdparm -i /dev/sdb /dev/sdb: SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 10 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 HDIO_GET_IDENTITY failed: Invalid argument Gparted correctly identifies the drive as SAMSUNG MP0402H. Any ideas how to remedy the HDIO & SG_IO messages?

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...
