The display on my Access Indigo (VERSION TWO) was hard to read unless the room was dark.
This annoyed me so much I was willing to risk damaging it to replace the display with one that was easier to read.
I ordered the following:
* LED back lit. The original was fluorescent front lit.
* More blue than than indigo in color.
* The 4 screw holes are a tiny bit too small. They had to be shaved larger with an x-acto knife.
I'd rather have gotten a nice OLED or fluorescent display, but was unable to find a source matching the same form factor.
The most important thing when hunting for an alternative LCD display is getting one with a matching form factor. The Virus C/Indigo 2 use the uncommon 84mm x 44mm form size. Any other size will not fit without additional modifications.
Unsoldering the ribbon cable from the original display was difficult. Soldering it back on the replacement was a paint too.
In hindsight, I'd source out a ribbon cable with single in-line 16 pin connectors on both ends and solder pins onto the LCD module.
Here are some photos
While taking it apart I noticed this ad hoc revision on the DSP.
Use an x-acto knife to widen the screw holes a bit.
The original display (top) handled bleedthru from the fluorescent lamp by painting over it with black paint (or fingernail polish). I did the same with the replacement (bottom) using a permanent black marker and electrical tape.
