Replacement screen and now brightness won't increase

Q: Replacement screen and now brightness won't increase

Hi all,

Bit of a tricky one here.

I just bought a replacement screen for my Dell Studio 17 1745. I don't believe it is actually a dell replacement part but here is the link. http://www.laptop-lcd-screen.co.uk/laptopparts/DELL-STUDIO-17-1745-17.3-LAPTOP-SCREEN_12053.asp

Anyway fitted it, fairly straight forward, had some bother with a dodgy display cable but other than that seems to be working fine. Now here's where it gets tricky.

If I press brightness on the f keys, or through the system display properties I get nothing, not even mildly brighter or dimmer, yet the on screen brightness display shows up. Figure that one out! I'm totally stumped I've tried uninstalling and reinstalling the AMD HD drivers and got nowhere. I tried downloading a third party brightness and display adjustment piece of software but it couldn't even recognise my screen let alone let me do anything about the brightness.

And (this might help but to me it only makes things more confusing) when I start up the screen is so dark it's virtually off, no backlight or something I don't know but I can see a vague negative image of the windows logo. But once loaded the desktop and all programmes run normally, except the issue with not being able to change the brightness (which by the way isn't a huge problem, I'd increase slightly but it's fine).

Can anybody help me? I'm out of ideas

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: Replacement screen and now brightness won't increase

Does the replacement have exactly the same part number as the original screen ?
It should be written on the back of the screen assembly.

Assuming that it does double check all the cable connections, especially those to the inverter (which usually controls the brightness). Is it the original inverter ?

One blaring problem is the screen isnt bright AT ALL. for example, when holding up my cell phone next to the display on this page its obvious that the color white on the 7570 isnt really white but a faded gray color. Is there any way to make the screen brighter or calibrate the colors so white is actually white or is dell just using garbage panels for their inspiron line.

A:New Inspiron 15 7570: Any way to increase screen brightness?

I assume you've already maxed out the display brightness using the keys on the keyboard dedicated to that purpose?  If so, make sure Adaptive Brightness is disabled under Advanced Power Options > Display since that can sometimes reduce brightness due to ambient lighting.  If that still doesn't get you where you want to be, then it's possible the display simply can't go as bright as you wanted, although comparing to a smartphone isn't exactly fair.  Smartphones are designed to be usable outdoors, which requires far higher brightness to achieve, whereas laptops typically are not designed for that particular use case -- but the result is that smartphones will practically always be brighter than laptop displays.

I recently decided to upgrade my default screen in my T450s to a newer 1920x1080 ISP screen that I found on Amazon. The old one was getting scratched by the keyboard because I keep the laptop in my backpack during school. I had been doing some research and apparently a lot of 14" screens out on the market have a white listed EDID with Lenovo, and thus aren't compatible with the brightness funcion keys (I think I understood that correctly, I'm no tech genius). Is there any way to make the brightness keys work with the new screen, or should I return it and buy a different screen with a Lenovo friendly EDID. Please help, I've spent way to long trying to fix this issue.  I have... - (re)Installed many different video drivers from intel and lenovo.- Tried editing the EDID of the new screen to match the EDID of the old screen.

I have a really old monitor and it's very dark. I have the brightness turned all the way up on the monitor but it's still really dark. Does anyone know a way to get it brighter? Is there a program or something that I could run that brightens the display up?

I know this is possible because you can adjust the brightness in games and then minimize the game and Windows will be brighter. I just need some more practical way of doing it.

I don't know if it'll matter but I've got an NVIDIA GeForce3 (Ver. 6.14) graphics card.

And no, I'm not buying a new monitor quite yet.

You may be able to adjust the brightness in the display properties of your video card. Go to Display in Control Panel and then to settings and Advanced. My ATi card has gamma and brightness settings, yours should have some sort of setting too.

I like to set brightness to 50% at all times, but over the time it resets to the full strength (probably because of games), so I have to cut it by half again to 25% and then again to 14%, until it can not be lowered anymore, last time I ended somewhere around 3%.

I tried to set it to full, uninstall GPU drivers, restart, install them again, but it never got fixed.
It is not really a problem, I have it at 18% right now, I am just wondering, what is causing it?

A:Why does brightness increase over the time?

Display control centers usually mess with these settings.

For example AMD catalyst control center or Intel HD control center run services which might reset whatever you do.
making fixed changes there ( In control center ) could solve or at least explain what is going on.

Also Windows updates ( on fresh Windows usually ) reset screen settings.

I have a new z500 that I've downgraded to Windows 7 64bit. For the most part I have everything working. I accidentally hit the brightness + (yes, +) and it instantly dimmed the screen to where it is barely viewable. It seems that hitting that one key decreased the brightness to the minimum amount. I've rebooted, looked for a setting in the BIOS, hit the Brightness +/- and can't increase the brightness. It is interesting because the other hot keys work correctly. I've even upped the brightness in the Control Panel, but nothing seems to work. The screen is extremely dim whenever the machine is powered on (including the BIOS), not just in Windows. I tried a lot of intel chipset drivers, the available Intel HD 4000 drivers in Win8 and win7 too, but nothing working. Can someone please help with how to up the brightness?

I am not sure is this is the place to discuss this, but I'll give it a go.

I am currently running windows 7 (x64)on a laptop with 1GB of ram. And it runs really slow (like the 'I need to wait for the characters to show up when typing' kind of slow).

Ok, this x64 part was a mistake of course. I liked the idea to be able to run programs, even when there would be only a x64 edition of it.

I tried running window xp on it before and it works really well driverwise, however what kept me from downgrading until now is the following.

While in windows 7 there is an option to adjust the screen brightness in the power options and my screen can be really bright when I do not use this. I don't think my back-light is dimmable (or is it? I am talking about a Sony Vaio VPCW21S1E), the function probbably just adust the pixel 'transparency'.

I tried different programs under windows xp to change the screen brightness but most of them behaved really buggy. Any suggestions?

A:canot increase screen resolution

do you have a driver disk for your display adapter, if not, download drivers for it.

Then go to device manager again, select the display adapter, hit remove, reboot and let windows reinstall it. If windows finds the drivers for it fine, if not, install the drivers you downloaded, that should fix the problem one way or the other

also you should check and make sure your monitor is being detected properly in display properties.
same tab as resoloution, choose settings, monitor, is the monitor correct.

I'm using a Lenovo IdeaPad s10-3t, and its native resolution is 1024x600. Reading up on the 'tubes, I've been able to (as best as I can describe it) "virtually" increase my resolution to either 1024x768 or even 1152x864. (I accomplished this by editing some registry value.) From what I can tell, it then just resizes the screen to fit on my monitor. The problem here is that my native display is widescreen, and these increased options are not, so the screen gets stretched.

Is it possible to change my "virtual" resolution to something like 1366x768 or some other greater widescreen resolution and have it resize to my screen?

I've noticed this happen twice. All of a sudden the screen flickered for just a second and the colors on the screen got brighter. By brighter I mean the the actual color changed (ex. my blue taskbar looked grayish). Both times my laptop was plugged in and the second time it happened I simply unplugged the computer and it changed back. After plugging the adapter back in the screen went to plugged in settings, but did not change the colors. The two times were separated by about two weeks.

I'm curious what might be causing this. It's probably just some little bug with a driver but I wanted to know what you guys thought.

A:Screen brightness changes on its own?

Your computer's got an ambient light sensor to detect and automatically adjust screen brightness based on surrounding lighting. You'll have to disable the setting. Lenovo has their own energy management program that has a setting for it, but I'd imagine there's something in the Control Panel (maybe Power Options?) that allows you to turn the setting off.

Hi: Did you install the graphics driver?  That would be the only suggestion I can offer. This package provides the driver that enables the Intel High-Definition (HD) Graphics in supported notebook models that are running a supported operating system. If high-definition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver. http://ftp.hp.com/pub/softpaq/sp75501-76000/sp75508.exe Check to ensure you see the Intel graphics adapter listed in the device manager under the display adapters device manager category. If you see a Standard VGA Adapter, that means the graphics driver did not install.

Now, when I right click and select display settings, the brightness adjustment bar is no longer there.Currently the display is too bright and is quite glaring causing eye strain.Any help would be welcome.ThanksDaniel
