Re: Don't get ripped off on an SXGA+ screen for your X61/X62

I'm still getting to rebuilding the screens (I'm getting to the work here and there). Most will be in good shape once I finish, but I've had to carefully disassemble and evaluate each one. I'm getting there--- I need to finish my T70 QXGA rebuilds first. I'll get back in touch with people when scree...

Re: Legit SXGA screens available for X62 builders

Still re-rebuilding the Chinese screens, just so there are no surprises. Sorry about the lag, I don't have as much free time right now as I used to :-|

Re: Don't get ripped off on an SXGA+ screen for your X61/X62

Mine happens specifically when I close the screen but don't turn it off. That seems to me like it's a temperature problem or something, since the screen would be heated up by the laptop body (maybe). In my case the edge turns completely white, regardless of what's being displayed and I can repeated...

Here is a picture from the german forum of a T60 with a very similar effect:

Yeah, it's in the same place but looks quite different from what I'm seeing.

Re: Don't get ripped off on an SXGA+ screen for your X61/X62

Thanks, but I do have lots of dark gray test images. *nod*, just giving you my specific worst-case test screen for the examples here. I can say that the retro-tv effect can get better by time. Takes several months. I always thought the effect was due to static electricity in the layers of the scree...

Re: Don't get ripped off on an SXGA+ screen for your X61/X62

I tweaked it the other direction and the problem disappeared. By how much did you turn it? Tried it on a screen without the retro-tv effect with no visible effect. I have two screens with darker left side edge and corners. But I cannot imagine how I could have managed to change the adjustment of VR...

Hi Xiphmont. Are the digitizers on these SXGA screens pen-enabled or just touch? Would be interested in a couple of screens if pen-enabled as well. Thanks. Regards.

https://xiphmont.dreamwidth.org/92996.html tl;dr summary: many (most?) of the 12" HV121P01 SXGA screens with a 'bathtub ring' or 'retro-tv' effect around the edges are not defective, VR1 simply got knocked out of adjustment.

Re: Don't get ripped off on an SXGA+ screen for your X61/X62

Tangentially related question, I have a pair of X60s-es with spotty screens so I'm scouting for replacements. It's not just a drop-in replacement for IPS screens, is it? (Even with just the XGA one.) In this somewhat old guide for putting an IPS in non-Tablets, it mentions a converter cable is requ...

Interesting. My SXGA+ has the damaged polarizer pattern sometimes (when it gets hot / close the lid with the screen on), but I get a white ring around the edge with that exact shape. Is that the same or something else? I pulled this from a tablet with everything on it (clips, digitizer, front plate...

As it has long received a test kit. It looks like my LEDs are degraded. :( Now I can get a maximum of 40-50 nits units.
Perhaps, this problem was due to overheating.
