Sooooo ... I went and bought a used and cheap LCD Philips 19" TV that had a lot of inputs (SCART, HDMI, Composite, ...). I figured that for 20 euros, and with a brand like Philips, I could not go wrong.

Well, I was wrong. It has very active anti-aliasing filter and deinterlacing, so the pixels are merged and too smooth, you cannot differentiate clearly one pixel from another. Furthermore, the image "vibrates", it is not static and very tiring for the eye, unless you sit 2 or 3 meters away.

Frustrating.
Back to square one.

The SCART inputs on LCD TVs are always crappy quality image for home computers and consoles. They use chips made for VHS that apply deinterlacing algorithms, and are cheap. Yours sounds like it’s even worse than my LCD TV, which looked decent on still images, but for moving characters deinterlacing artifacts started to appear.

I really recommend the OSSC for the image quality and zero latency. It was recently reduced a bit in price too. What display you connect to it then doesn’t really matter, as long as it has HDMI input. I use a nice 23" Dell U2312HM, it is low-latency and has an IPS display with good colour reproduction, it’s 16:9 but looks good and I don’t mind the letterbox bars.

True, OSSC is about 130 euros without VAT here : https://videogameperfection.com/products/open-source-scan-co...
It might be the best solution after all ...

EDIT : I'm confused though. What is the output resolution that the OSSC is able to do with our MSX ? And what does the PAL MSX outputs ? 288p ? 576i ?

EDIT 2 : Chinese ones are less expensive, about 125 euros, shipping included.

PAL MSX outputs 288p normally, 576i in interlaced mode.

You bring up a point though. Although I use an NTSC turboR usually, my Dell monitor handles PAL as sent by the OSSC well. However it is not a standard HDMI resolution, so compatibility will be less than NTSC which outputs 720p in x3 mode. I notice that on my Samsung TV in the living room PAL only x2 mode works (576p, also a standard resolution), while NTSC works in x1-x4 modes.

They are developing a next generation OSSC which also has a frame buffer giving it more flexibility to make a trade-off between latency and compatibility / flexibility, however I think it’ll take a while before that becomes available.

Yes, it seems to me that the NTSC inputs have an advantage over PAL with the OSSC.
. NTSC gives 720p with x3 mode
. PAL gives only 576p with x2 mode

How small are you looking to get? I'm currently using an 8" field monitor for my file server, it's one of the Chinese ones sold under various names on Amazon. I've also got a 10" monitor that I use with my Altair clone. That one only has HDMI and VGA, but it's easy enough to use with something like a RetroTink converter.

Check out "Raspberry Pi" monitors on EBay or Amazon. There are a bunch in the 8-10" range.

Also, you might look for a Dell 2001FP monitor. I found one at a thrift store, and it has done every video format I've thrown at it: PAL, NTSC, VGA, even HDMI to DVI. The only thing it can't handle is 50Hz HDMI - but my other computer monitors deal fine with that...
