Which is better?
Hi,
I have an Acer 1600x900 K2O2HQL monitor connected to a Win10 PC. After Windows update I noted that the monitor image was blurry and streaked. I looked into the matter and downloaded an Acer device drive for Win8, the latest listed by Acer and installed it. It fixed the problem, but the image is still not as crisp as the Acer Logo on power up. Acer also lists a drive for Win7. Which is better? Is there any good compatible driver for Win10. Thanks. |

So this is a question about what drivers are available for the video card on the Windows 10 PC ? According to this Walmart advert, the K202HQL is 1366x768. Typically a video driver needs to make 1360x768 or 1368x768, as "horizontal divisible by 8" is preferred. To make 1366 on a modern GPU, that can be done with an outboard Silicon Image chip sitting next to the video card GPU. It apparently has the clocking options to hit 1366. https://www.walmart.com/ip/Acer-K202...nitor/49688385 You can use Moninfo to tease out the details of the monitor right now, using the "real time sampling" option. Scrolling down the right-hand pane, after querying the monitor, should give a list of resolutions from the monitor. https://www.entechtaiwan.com/util/moninfo.shtm Then we have to find out some details about the video card on your computing device. I think Windows 10 may have removed the custom resolution box, but the hardware will continue to support mode line programming, as that has been in silicon for *50 years*. No matter what the price, I do not in general recommend anyone buy a 1366 monitor... If they want to putz around, a 1440x900 (like the end of line I bought at Staples) is a much better purchase. I haven't had a problem getting a video card to drive that. My monitor had one bad pixel, but I expect that's a function of the panel class used (they're not using "A" panels in that thing, so you can't actually cherry pick a good panel from the lot). In any case, it is possible to make your setup work nice. It's just getting harder and harder and harder, to do. (Thanks, Microsoft.) Paul |

Did you check the Windows setting for screen resolution to make sure it matches the monitor's native resolution? If screen resolution doesn't match monitor resolution, the OS has to interpolate the rendering which can cause loss of focus, color tinging, and other artifacts. From what I've found little online for the specifications on the Acer K2O2HQL monitor (probably it's very old), its native resolution is 1366x768, not the 1600x900 that you mentioned. You are trying to use a resolution in the OS that exceeds what the monitor itself can support. Go to Settings app - Display - Display. When installing the monitor's driver (very likely just an INF file to define the device), is the correct monitor listed there under "Color profile"? If you monitor is not listed, is Generic listed? For generic, you'll likely have to make sure *you* pick a screen resolution that matches the monitor's resolution. What is the "Display resolution" setting there? Then click on "Advanced display settings" and click on "Display adapter properties for Display 1" and go to the Monitor tab. Is the "Hide modes that this monitor cannot display" option enabled (or grayed out if the driver prevents selecting unsupported modes)? Is it just text, or is both text and graphics (e.g., icons) fuzzy? If just text, did you check Clear Text is enabled? Enter "cleartext" in the taskbar's search box to check if Clear Text is enabled or not. |

Thanks Paul,
While Acer does make a 1366x768 monitor, it is not K2O2HQL. The Walmart ad says it is K202HQL ABD. The Amazon ad says it is 1600x900, its native resolution.

So, did you check the screen in Windows is running at the same resolution as the native resolution for the monitor? Did you check Clear Text? |

Piriform's Speccy reports the monitor's resolution. So does the msinfo32.exe tool alrady included in Windows. I am not sure that is the current resolution or the maximum resolution reported a reported by the monitor (via the EDID from the monitor). The monitor has both VGA and HDMI connections, but the OP didn't say which he is using. https://en.wikipedia.org/wiki/Displa...#Physical_link DDCv1 could only identify if the monitor supported resolutions higher than 1024x768. Looks like later versions serialized the data transfer, so more of the EDID (Extended Display Information Data) could be retrieved from the monitor. https://en.wikipedia.org/wiki/Extend...ification_Data While VGA supports up to 1080p (1920x1080), image quality degrades at higher bandwidths due to the intrinsic nature of analogue signalling. https://en.wikipedia.org/wiki/Video_Graphics_Array Today, the VGA analog interface is used for high-definition video, including resolutions of 1080p and higher. While the transmission \ bandwidth of VGA is high enough to support even higher resolution playback, there can be picture quality degradation depending on cable quality and length. How discernible this degradation depends on the individual's eyesight and the display, though it is more noticeable when switching to and from digital inputs like HDMI, DVI or DisplayPort. I've seen users that reported problems when using VGA that sufficiently cleared up to their satisfaction after replacing the video cable with a higher quality one. With analog, like VGA, the quality of the cable and its connections significantly impact the quality of the signal. In monitors that still have VGA input, the scalers (to convert analog to digital) in the digital monitors have degraded because VGA is an antique standard that was getting phased out 10 years ago. I don't know the vintage for the OP's monitor, and the video card was never mentioned (or the mobo brand and model if the OP is using onboard video). If the OP has an HDMI port on his unidentified video card (already known his monitor has it), he should invest in getting an HDMI cable. And, no, not use a VGA-to-HDMI converter. Unless the OP configured Windows 10 otherwise, it will push driver updates. I have that disabled. If there are new drivers, I'll get them from the device manufacture *if* they provide anything better than what the old drivers are doing okay, so far. As yet, we don't know what was in the unidentified Windows update mentioned by the OP. |

True. From your other post, in this day and age, it is very daft for a company to have the same model number with different specifications depending on region in the world. |

Why not take a look at your monitor driver, to see you have the correct file ? Not all monitors have monitor drivers. The "Westinghouse" brand LCD monitors, have no monitor files, and all of those show up as "generic monitor" in Device Manager. Yet, the screen always works well... because the EDID table provides the information used to make the thing work. The monitor driver is optional. Companies like NEC, provide a lot of (vanity) monitor drivers for their customer. Like this one. nl1765.cat security file nl1765.icm color calibration table (generic, unlike a Spyder one done for the monitor) nl1765.inf has a few registry changes (you should read those!!!) === === === has the device string for Device Manager example: NEC-LCD1765="NEC LCD1765" If any file is going to screw up, that's the INF one. Other than that file, and any information (that might actually be ignored by the video card driver), it's between the EDID and the video card, to work out the resolution choices Monitor EDID ------- serial ---------- video-card select possible res, use it ------------------------------ (video signal) The INF file is anonymized during installation. nl1765.inf gets changed to "oem23.inf". That would be the twenty third file added to the INF folder. if you do a content search against the INF folder, using a string like my example "nl1765", you will be able to find the INF file which is actually being used at the moment. Your first hint regarding the analysis, is to start with the Device Manager and see if a vanity string is present for the LCD monitor. If it says "generic whatever", then you know that no monitor file is present, and the EDID table provides what the video card is looking for. If a monitor driver has been used, then track it down... and read it. Check the INF for "dumb stuff". Paul |
