PMDG 777 FSX Display issue

Hi

I posted this in another forum but sadly did not receive any response, I am using FSX SP1 and SP2, my graphic card is AMD Radeon HD6800 series with the most latest driver being in 2015 as it is an old Graphic card.  However please see the photo, as you can see the text looks compacted, for example the ground speed, "GS" the font looks squashed along with the readout of the wind direction "090".  I would be very grateful for any help.

Thanking you in advance.

I use Windows 10

 

My specification is:

Intel R Core i-5 -3450 CPU@ 3.10Ghz 3101 mhz, 4 Cores

Installed Physical Memory RAM 8.00GB
