Need help identifying LCD Panel type

Hi,

I've been reading this site for quite some time and only now took the courage to make a contribution and becoming a member :)

For about 5 years I've been using the same LCD and am thinking about an upgrade. Not that there is something wrong with it, just want to use a 16:9, I figure it's better to have almost two full pages side by side while text editing or programming.

I'm trying to figure out from what point I should upgrade to... I can't identify the Panel Type of the current LCD that I have. The monitor is a 19" Sceptre X9G Komodo IV S1902D - I've searched the net and couldn't find its type. I'm almost sure it's not TN: Color and brightness stay the same even when looking from all 4 sides, it has 75Hz refresh rate and a snailish 25ms response time. I've used a TN panel at work and don't really like it for photo processing and overall use. Then it can't be one of those top of the line Panels (PVA?) since it was about $500 new in '04...

I'll include the specs, hope someone can let me know what kind of panel it has.

For more info, it can be found here.


Thanks, Josh
 
Hi Josh

Try looking at the panel from belw (angle +45 degrees). If contrast is reduced a lot and colours become almost "complementary"/screwed then your're sure that it's a TN panel.

If not, then it's probably not a TN. :)
 
Hi Mistar

Quite strange, when looking from below at any angle, contrast, color and brightness remain the same, even if I were to touch the LCD, probably at an angle of <10 degrees. It baffles me since I can't compare it to other e-IPS, PVA or other types of displays since no stores around here seem to carry them.
 
FYI...

All 16:9 LCD monitors (1920 x 1080) use TN panels.

If you are looking for a non-TN panel 16:10 monitor (1920 x 1200), then you will need to a minimum of $575 (based on Newegg.com prices).
 
According to the following thread, the poster states the X9G Komodo IV uses a TN panel. However, s/he does not state the source of the information.

The listed Response Time of 12ms is probrobly GTG instead of BTB. BTB fell out of favor several years ago because "Black To Black" response times are higher than "Grey To Grey".

It's a 19-inch non-widescreen monitor several year old. Back in the days we actually had some 18-19-inch IPS based monitors. TN panels were not as common.

I don't see any X9G Komodo IV in the list? Only a X7G Komodo IV and some other X9G komodo monitors?
 
Every where I'm finding it says it's a 24bit panel, so it can't be a TN. It's most likely an IPS since they were more popular back then than VA based panels.
 
If viewing angles are good then it must be a IPS.

Back in 2003-2004 there existed the LG.Philips IPS (LM190E01-C4 / LM190E02) and the Hitachi IPS (TX48D11VC0CAB) both having a response time of 25 ms.
LG.Philips also made a IPS called LM190E05 but this was a 18 ms panel.

All of the panels have been found here: http://www.flatpanelshd.com/panels.php
 
I thought I should post some pics of the angles but I guess you guys (and gals) probably know how those angles look like. Let me know if I should post some pics, just in case...

Great info with the panel manufacturers, Mistar, I'm thinking about opening the back case and look for further data, hopefully printed on the back panel itself.
Any chance for such details to be found in there?
 
Yeah, I think you will be able to see the full spec on the panel there. :)

The OP stated he was looking into purchasing a 16:9 LCD monitor in his second paragraph which is why I stated they are all TN panels.

Here's the rub...

Manufacturers have listed 6-bit TN with 2-bit FRC as "8-bit" in the past; which translates to "24-bit".

Also, since all other Sceptre's X9G Komodo series monitor (from the link I provided) are TN panel based, it is very likely the "IV" is also TN as well.
