How to improve VGA quality? I have a 1080p LG LCD Monitor.
It has 2 inputs, DVI and VGA. I have two different types of cables, HDMI-DVI and VGA-VGA. I tried connecting my laptop to the monitor.
My laptop has two outputs, VGA and HDMI. When I use the HDMI output, the image on my monitor is sharp and clear. When I use the VGA output and the VGA-VGA cable, the image on my monitor is blurry.
Is there any fix?
EDIT: My VGA connector also has one peculiarity. From the point of view of the sockets, Pin No. 9 is missing, for both ends. (although it may unused)

The vga cable has a lower resolution than HDMI and the HDMI cable is designed to carry the 1080p resolution along with sound. Stick with the HDMI cable it's much better as you found out. | My System Specs | | System Manufacturer/Model Number Custom built OS Windows 7 Ultimate 64 bit CPU AMD Phenom II X4 965 Black Edition Motherboard Gigabyte GA-MA790X-DS4 Memory GSkill 4 X 2 GB PC 8500 Graphics Card XFX Radeon HD 6790 D Sound Card On board RealTek HD Monitor(s) Displays Dual monitors:Samsung SyncMaster S20B300 Screen Resolution 1600 X 900 Keyboard Logitech G510 Mouse Razor DeathAdder PSU Ultra X4 750 watt fully modular Case Thermaltake Overseer RX 1 full tower Cooling Core-Contact 92 mm CPU Cooler Hard Drives Seagate Barracuda 1TB (primary)

Are you sure my problem is due to the limitations of VGA?
My VGA connector also has one peculiarity. From the point of view of the sockets, Pin No. 9 is missing, for both ends. (although it may unused)
Lastly, I've been checking other forums, where they say that HDMI produces no noticeable video quality improvement over VGA. | My System Specs | | OS Windows 7 Home Premium 64bit |

VGA is very old and is worse than HDMI, but for most non-TV resolutions it's the same, and all VGA cables I know have all the pins. This post says what the pin 9 does on a VGA.
I'd frankly buy another VGA cable just in case. | My System Specs | | Computer type PC/Desktop System Manufacturer/Model Number custom built OS Win 7 Pro 64-bit 7601 CPU AMD Phenom 9650 QuadCore, revision DR-B3 Motherboard ASUS M4A78 Memory 4,00 GB Graphics Card NVIDIA GeForce 9800 GT Sound Card Realtek High Definition Audio Monitor(s) Displays Fujitsu Siemens P19-3P Screen Resolution 1280 x 1024 x 32 bits @ 60 Hz Oh yeah, 4:3 rocks!

Was running Win Xp from a IDE drive. Yeah. Was a pain.

Thanks. But what do you mean by non-TV resolutions? My monitor is 19" 1080p.
I notice a substantial drop in image sharpness, still not sure if that is considered normal. | My System Specs | | OS Windows 7 Home Premium 64bit |

non-TV resolution is a resolution of a computer screen. TVs are different, and depending on model they may be throttling down input from VGA for uhm... marketing reasons.
VGA is able to handle 1080p just fine (you don't notice the difference between VGA, DVI and HDMI), so I think your cable is damaged/old/defective. Cables can screw up things and I fixed quite a few "video issues" by changing the VGA cable. Quote: I notice a substantial drop in image sharpness, still not sure if that is considered normal. It's not normal.
Can you check that windows is set to run at the right resolution? (right click on an empty spot of the desktop, and select Screen Resolution to access the relevant settings panel) the VGA cable you are using (that lacks pin number 9) prevents the monitor from telling its specs to the computer, so you have to set the resolution manually.
Again, buying a VGA cable with all pins in their place allows the screen to communicate with the computer, and if that was the case Windows 7 will start spamming popups saying "this resolution is not optimal" offering you to set it to the screen's native resolution. | My System Specs | | Computer type PC/Desktop System Manufacturer/Model Number custom built OS Win 7 Pro 64-bit 7601 CPU AMD Phenom 9650 QuadCore, revision DR-B3 Motherboard ASUS M4A78 Memory 4,00 GB Graphics Card NVIDIA GeForce 9800 GT Sound Card Realtek High Definition Audio Monitor(s) Displays Fujitsu Siemens P19-3P Screen Resolution 1280 x 1024 x 32 bits @ 60 Hz Oh yeah, 4:3 rocks!

I'd frankly buy another VGA cable just in case. Well, tell that to bassfisher6522. I tried another VGA cable and got the same result. | My System Specs | | OS Windows 7 Home Premium 64bit |

Heh, I'd say the port on either the laptop or the monitor is damaged then. Try using the VGA on another monitor, and if it works fine the broken port is the one of the monitor.
Also, what is that laptop's graphic card? Intel ones sometimes hate some screens for unknown reasons. | My System Specs | | Computer type PC/Desktop System Manufacturer/Model Number custom built OS Win 7 Pro 64-bit 7601 CPU AMD Phenom 9650 QuadCore, revision DR-B3 Motherboard ASUS M4A78 Memory 4,00 GB Graphics Card NVIDIA GeForce 9800 GT Sound Card Realtek High Definition Audio Monitor(s) Displays Fujitsu Siemens P19-3P Screen Resolution 1280 x 1024 x 32 bits @ 60 Hz Oh yeah, 4:3 rocks!
