I bought a 40" Element ELEFW408 for dirt cheap to use as a computer monitor for web browsing and the occasional game/movie (my projector is for the heavy gaming sessions/movie watching). Unfortunately this TV has a heavy bias towards making all but pure reds look more like magenta-red (you get what you pay for, right?).
Disappointed with the picture adjustment settings available -- Color, Tint, Sharpness, Brightness, Contrast, and Color Temperature, and only Contrast, Brightness, and Color Temp can be changed when the TV detects a PC input -- I decided to dive into the service menu to see if I couldn't find some hidden settings that would help make this display a bit more palatable to the eyes (hit Menu on the remote, then type 0000):
Here is the first screen. Everything highlighted in green are menus I've entered. Yellow
are menus I haven't entered but have a good idea of what's in them. Reds
are what I'm completely clueless about and am too scared to enter without further advice from the community, hence this thread. Greens
are menus I've entered and will go over in this thread. The first option was supposed to be highlighted yellow, but I forgot and am too lazy to edit the pic.
This is where the "Others" option takes you, and right away my pupils widened. What's this? More color adjustment settings? Couldn't be! Let's dig deeper to see what we can find. First let's try the promising "Color Temp" option...
Holy ****! Success! Here is the menu that lets you set the default color values for the three color temperature options available in the user menu (Cool, Normal, Warm). Unfortunately my excitement was short lived as I noticed that while the classic Gain and Offset adjustments are available, the one setting I needed the most in order to get rid of that magenta glow -- Hue -- is missing. Still, even with these options alone I was able to get closer to a more natural picture after playing with these settings for awhile (I have to eyeball everything with test patterns on Lagom.nl
since I can't afford fancy calibration gear). I hit "Save to EEPROM" numerous times after trying one adjustment then moving to the other, which I hope isn't damaging anything! (It isn't, right?)
Let's keep digging further to see what else we can find...
The "Video Quality" and "Sound Quality" menus were pretty boring -- Just a place to change the default settings for each picture and sound mode (Vivid/Standard/Movie/etc. - Music/Movie/Flat/etc.) -- so I skipped on taking pics of them as they have the exact same options as the user menu. But curiously enough, the "Video Quality" menu lets me adjust the settings that are greyed-out when using a PC input, except Tint. I still left them as default, as the ability to adjust "Color" isn't very useful when dealing with PC inputs, especially since I have the more accurate Gain & Offset dials to play with now. Sharpness was already at where it needed to be as well judging by this test pattern
. Moving on to "Curve Setting"...
That opens this submenu. Let's try "Video Curve Setting" first:
Well this is where I get a little lost. The highlighted option "Curve Setting" scrolls through all the user menu picture adjustment settings, even the ones that are greyed-out when using a PC input. I'm guessing that this controls the strength curve of the user settings i.e. when Contrast is set to 0 in the user menu it's actual value is 80. (OSD_0 = 80). Makes sense to me. I bet I could play with the Color curve to get rid of what's left of that magenta hue, but I've decided to leave these settings alone just in case my theory's wrong.
And here's the Sound Curve menu. Seems to be the same concept, except for audio. If I'm not using headphones I'm using my 7.1 setup, so none of these settings are useful. Next!
Alright so next on the list is "OverScan". I'm already getting a 1:1 pixel ratio out of this TV, so no need to even risk going into this menu and screwing things up. Still, my curiosity is starting to get the best of me. MUST. RESIST. URGE. TO. ENTER. MENU.
Next is "Aging Mode" and "Other Setting". The latter we'll come back to in a second, but first let's talk about "Aging Mode". This option is the reason why I'm scared of entering other screens without consulting you guys first. Every option in this menu looks like it'll take you into a submenu, right? That's not the case with "Aging Mode". The second you hit it, the screen goes immediately blank then starts cycling through Red, Green, Blue, Black, and White. Apparently this menu is for breaking in the TV before you do your calibrations. Might be useful for fixing stuck pixels/image retention as well. What scared me so much is that there seemed to be no way to exit this mode. After trying every single button on the remote and bezel I eventually took a deep breath and hit the power button. Thankfully the TV went back to normal after powering back on.
Next on the list of menus I've explored is "Audio Setting". This is all gibberish to me so I don't mess with it. But part of me still wants to know what this is all about. But for now, let's move on to the grand finale, the "Other Setting" screen:
More Gibberish! "TI MODE"? "SSC Settings"? What is all this nonsense? But wait, among the nonsense what have we found? A BACKLIGHT SETTING!?!?!?
What's this doing here??? Why isn't it in the user menu? This bastard was cranked to 100%! While it looked absolutely stunning
in the store (especially for a $250 TV), 100% backlight brightness is absolute insanity
at home. I set it to a more reasonable 40% for daytime viewing, and 10% at night. I just don't understand why it's buried deep in the service menu instead of hanging out with the other user picture settings. Was it a beta feature that wasn't ready for release in time to ship? It seems to work just normally, but I can't help but wonder if I'm harming my TV every time I adjust it (twice a day). The fact that I don't have to "Save to EEPROM" every time I adjust it does make me feel a bit better about playing with it, but still...
So to tl;dr
everything up: Gain/Offset and Backlight are the only settings in the service menu I'm comfortable enough with to mess with. The following settings are a complete mystery however, and I'd love to hear everybody's input on what they could possibly do:
Others > ADC Setting
Others > Shipment
Others > Other Setting > Power ON Mode
Others > Other Setting > TI MODE
Others > Other Setting > SWAP MODE
Others > Other Setting > Uart Mode
Others > Other Setting > SSC Setting
Others > Other Setting > Key Debug
Others > Other Setting > Factory IR Mode
Others > Other Setting > Mirror Control
Others > Other Setting > Rest PreChannel
Thanks in advance for the feedback.
Oh and mods, I couldn't decide if this thread should go in Display Calibration or LCD Flat Panel Displays. Feel free to move it where it fits best.
