Hi everyone... well its been a frustrating few days for me ![]()
Solution 1: Make sure the computer BIOS is updated - Done, but no help
Solution 2: Ground pins 6,7,8,10 - not attempted yet
Solution 3: Update TV firmware - not attempted yer
Solution 4: Does pin 9 have +5V - yes, it does.
Someone please help by answering my questions on #s 2 and 3 in the original post! In the meantime I'm going cable shopping again...
Hey all... I bought a LN40A550 recently and was keen on hooking it up to my laptop (HP dv6000t) as a monitor. Of course, I found that using the VGA cable I had the PC detects the TV just fine (and allows me to configure 1920x1080, 60Hz too) but the TV wont "whiten" the PC source.
After a lot of googling and searching, I landed on this forum and found some hope. Now, I've done a lot of info-mining and come up with this list of solutions... but I have supplementary questions on almost all of them. Would appreciate the help if someone could answer them:
Solution 1: Make sure the computer BIOS is updated
My question: does this apply to HP laptops too? I use an NVIDIA GeForce 9400 video card btw. The BIOS on the laptop is probably a year or so old.
Solution 2: Ground pins 6, 7, 8, 10 of the 'bad' VGA cable and see if it works
My question: Do I do this on both ends (I have a male to male cable)? Also, is it enough to just loop a wire around the target pins and connect it to the metal casing, or will I need to find my soldering iron?
Solution 3: Update TV firmware...
Question: Is this necessary? I have the new 40A550 with the 40,000:1 contrast ratio... will it have the latest firmware? What is the latest version?
Also, I have no idea how to go about a) checking the firmware version, and b) updating the firmware if that is indeed recommended.
Solution 4: Check if pin 9 has a +5V for the TV to detect
My question: It probably does, but I'd have to buy a multimeter to be absolutely certain. My circuiteering days are long behind me
Can I assume it does and carry on?
Also, does the TV detect a change in potential, or the potential itself? Knowing that might mean I just need to change the sequence in which I boot my systems.
I'm posting this from work and won't be "implementing" any solutions for at least 7 hours... so would really appreciate your clarifications on any solutions listed above, or any additional tips.
Hat tip to budwich for the fantastic cabling tips btw...
